6. Edit the generated controller in “grails-app/controllers/HomeController.groovy” such that it looks like:
   

   class HomeController {     def index = {         render “Grails using embedded GlassFish!”     } }

7. Refresh the web page in the browser and it looks like:

   

   and clicking on “HomeController” shows the output as:

   

More details about GlassFish embedding in Grails are available here.

This application can also be deployed on stand-alone GlassFish v3 Technology Preview 2 a
s explained here. This blog explains how to configure JNDI resources for a Grails application and I plan to explore that in upcoming days.

Once the Servlet engine in Grails is made configurable then GlassFish can be used as the target deployment platform from “run-app” script.

NetBeans 6.5 M1 provide extensive support on Grails application development – details are available here.

Technorati: grails glassfish v3 embedded netbeans

There are several JavaScript libraries that can be embedded in your webapplication to create a visually appealing interface. Script.aculo.us is one of the popular ones and is built on the Prototype JavaScript Framework. The library provides an easy-to-use, cross-browser user interface JavaScripts that allows you to create fancy effects commonly visible on web pages these days.

This blog entry gets you started by using Ajax.Autocompleter that allows for server-powered autocompleting of text fields. Basically, you type a character in a text field and suggestions for possible correct values starting with that character are shown . This is achieved by by sending an Ajax request to the data source on server, passing the typed character in the request and processing the response to display on the web page. This effect was first popularized by Google Suggest.

In this TOTD (Tip Of The Day) we will create a simple web application with a text field in a JSP page that will use Servlet as the data source. The Servlet retrieves the parameter from the RequestContext, uses Java Persistence API to query the database and return response in the expected format. We will use:

• NetBeans IDE 6.1 for Web app creation/deployment
• GlassFish v2 UR2 as deployment platform
• MySQL database server bundled with Mac OSX 10.5.4

Let’s get started!

1. TOTD #38 explains how to create a MySQL Persistence Unit. Please follow the steps there to create a new Web application and Persistence Unit. Follow the steps listed below after the PU is created.
   1. In Project Explorer, expand “Source Packages”, “server” and open “States” class. Add the following NamedQuery:

      @NamedQuery(name = “States.findLikeName”, query = “SELECT s FROM States s WHERE LOWER(s.name) LIKE :searchString”),

      at the position shown below:

      

   2. In “StatesServlet” class, replace the commented code in “processRequest” with the following fragment:
      

      String searchString = request.getParameter(“autocomplete_parameter”);             List<States> list = em.createNamedQuery(“States.findLikeName”).                     setParameter(“searchString”, searchString.toLowerCase() + “%”).                     getResultList();             out.println(“<ul>”);             for (int i = 0; i < list.size(); i++) {                 States s = list.get(i);                 out.println(“<li>” + s.getName() + “</li>”);             }             out.println(“</ul>”);

      and fix the imports by right-clicking in editor pane and selecting “Fix Imports”.

2. Download & Use Script.aculo.us libraries
   1. Download latest Script.aculo.us libraries from here (version 1.8.1 as of this writing) and unzip them.
   2. In NetBeans, right-click on “Web Pages”, select “New”, “Folder” and specify the folder name as “javascripts”.
   3. From the unzipped Script.aculo.us bundle, copy all files from “src” and “lib” directory to the newly created “javascripts” folder.
   4. Expand “Web Pages” and open “index.jsp”. Add the following fragment in HTML <head>:
      

      <script src=”javascripts/prototype.js” type=”text/javascript”></script>         <script src=”javascripts/scriptaculous.js?load=effects,controls” type=”text/javascript”></script>         <script type=”text/javascript”>             window.onload = function() {                 new Ajax.Autocompleter(“autocomplete”, “autocomplete_choices”, “/Autocomplete/StatesServlet”, {});             }         </script>

      and the following in HTML <body>:

      <input type=”text” id=”autocomplete” name=”autocomplete_parameter”/>         <div id=”autocomplete_choices” class=”autocomplete”></div>

      These fragments are part of the original tutorial.

   5. Optionally, specify a stylesheet to render the result nicely
      1. Create a “stylesheets” folder in “Web pages”.
      2. Right -click on the newly created folder, select “New”, “Other…”, “Other” category and “Cascading Style Sheet” file type. Give the name “autocompleter” and click on “Finish”.
      3. Replace the generated template with the following contents:
         

         .autocomplete {     position:absolute;     width:250px;     background-color:white;     margin:0px;     padding:0px;     overflow:hidden; } .autocomplete ul {     list-style-type:none;     margin:0px;     padding:0px;     overflow:auto; } .autocomplete ul li.selected { background-color: #ffb;} .autocomplete ul li {     list-style-type:none;     display:block;     margin:0;     padding:2px;     height:32px;     cursor:pointer; }

      4. Add the following fragment in “index.jsp” in <head>:
         

         <LINK href=”stylesheets/autocompleter.css” rel=”stylesheet” type=”text/css”>

Now the show time … right-click the project and select “Run”. This deploys the project on GlassFish v2 and brings up “http://localhost:8080/Autocomplete/index.jsp” in the default browser window. The default page looks like:

As you start typing characters in the text box, Ajax.Autocompleter sends a request to the Servlet (specified using the “/Autocomplete/StatesServlet”) by passing the typed characters as query parameters. The servlet returns an unordered HTML list. Typing “A” in the text box shows the following output:

and Firebug output looks like:

Typing “C” in the text box shows the following output:

Typing “Mi” in the text box shows the following output:

A request to the Servlet is made everytime a letter is typed. The minimum number of characters that must be entered in the field before a Servlet request is made can be altered by passing the arguments to Ajax.Autocompleter function as shown below (changes highligted in bold):

window.onload = function() {                 new Ajax.Autocompleter(“autocomplete”, “autocomplete_choices”, “/Autocomplete/StatesServlet”, { minChars: 2 });             }

Some potential fun ideas to make this entry more meaningful:

• Servlet can access data from a RESTful endpoint and transform the data to an unordered list
• Autocompleter data source return data in JSON format
• Autocompleter used in a HTML <form> and “afterUpdateElement” is used to process the selected entry, may be filter the data shown

This TOTD (Tip Of The Day) shows how to create a Persistence Unit (PU) for a MySQL database using NetBeans IDE. This PU can then be used in any of Java EE artifacts (JSP, Servlet, EJB, …) for database interaction.

1. In NetBeans IDE, create a new project
   1. Create a new NetBeans Web project and enter the values (“Autocomplete”) as shown:

      

      and click on “Next”.

   2. Choose GlassFish v2 as the deployment server and then click on “Finish”.
2. Set up the database
   1. Start the database as:

      ~ >sudo mysqld_safe –user root Password:<YOUR PASSWORD> Starting mysqld daemon with databases from /usr/local/mysql/data

   2. Create a user, create the database and grant the privileges to newly created user as:
      

      mysql> CREATE USER duke IDENTIFIED by ‘duke’; Query OK, 0 rows affected (0.00 sec) mysql> create database states; Query OK, 1 row affected (0.00 sec) mysql> GRANT ALL on states.* TO duke; Query OK, 0 rows affected (0.00 sec)

   3. In NetBeans IDE, Services panel, right-click on Databases and click on “New Connection…” and enter the values as shown:

      

      and click on “OK” and again on “OK”.

   4. Right-click on the newly created database and select “Execute Command …” as shown:

      

   5. Create the database table as:
      

      CREATE TABLE STATES (       id INT,       abbrev VARCHAR(2),       name VARCHAR(50),       PRIMARY KEY (id) );

      and click on the green button to run the query as shown here:

      

   6. Following the same instructions, populate the table using the following SQL:
      

      INSERT INTO STATES VALUES (1, “AL”, “Alabama”); INSERT INTO STATES VALUES (2, “AK”, “Alaska”); INSERT INTO STATES VALUES (3, “AZ”, “Arizona”); INSERT INTO STATES VALUES (4, “AR”, “Arkansas”); INSERT INTO STATES VALUES (5, “CA”, “California”); INSERT INTO STATES VALUES (6, “CO”, “Colorado”); INSERT INTO STATES VALUES (7, “CT”, “Connecticut”); INSERT INTO STATES VALUES (8, “DE”, “Delaware”); INSERT INTO STATES VALUES (9, “GL”, “Florida”); INSERT INTO STATES VALUES (10, “GA”, “Georgia”); INSERT INTO STATES VALUES (11, “HI”, “Hawaii”); INSERT INTO STATES VALUES (12, “ID”, “Idaho”); INSERT INTO STATES VALUES (13, “IL”, “Illinois”); INSERT INTO STATES VALUES (14, “IN”, “Indiana”); INSERT INTO STATES VALUES (15, “IA”, “Iowa”); INSERT INTO STATES VALUES (16, “KS”, “Kansas”); INSERT INTO STATES VALUES (17, “KY”, “Kentucky”); INSERT INTO STATES VALUES (18, “LA”, “Louisiana”); INSERT INTO STATES VALUES (19, “ME”, “Maine”); INSERT INTO STATES VALUES (20, “MD”, “Maryland”); INSERT INTO STATES VALUES (21, “MA”, “Massachussetts”); INSERT INTO STATES VALUES (22, “MI”, “Michigan”); INSERT INTO STATES VALUES (23, “MN”, “Minnesota”); INSERT INTO STATES VALUES (24, “MS”, “Mississippi”); INSERT INTO STATES VALUES (25, “MO”, “Missouri”); INSERT INTO STATES VALUES (26, “MT”, “Montana”); INSERT INTO STATES VALUES (27, “NE”, “Nebraska”); INSERT INTO STATES VALUES (28, “NV”, “Nevada”); INSERT INTO STATES VALUES (29, “NH”, “New Hampshire”); INSERT INTO STATES VALUES (30, “NJ”, “New Jersey”); INSERT INTO STATES VALUES (31, “NM”, “New Mexico”); INSERT INTO STATES VALUES (32, “NY”, “New York”); INSERT INTO STATES VALUES (33, “NC”, “North Carolina”); INSERT INTO STATES VALUES (34, “ND”, “North Dakota”); INSERT INTO STATES VALUES (35, “OH”, “Ohio”); INSERT INTO STATES VALUES (36, “OK”, “Oklahoma”); INSERT INTO STATES VALUES (37, “OR”, “Orgeon”); INSERT INTO STATES VALUES (38, “PA”, “Pennsylvania”); INSERT INTO STATES VALUES (39, “RI”, “Rhode Island”); INSERT INTO STATES VALUES (40, “SC”, “South Carolina”); INSERT INTO STATES VALUES (41, “SD”, “South Dakota”); INSERT INTO STATES VALUES (42, “TN”, “Tennessee”); INSERT INTO STATES VALUES (43, “TX”, “Texas”); INSERT INTO STATES VALUES (44, “UT”, “Utah”); INSERT INTO STATES VALUES (45, “VT”, “Vermont”); INSERT INTO STATES VALUES (46, “VA”, “Virginia”); INSERT INTO STATES VALUES (47, “WA”, “Washington”); INSERT INTO STATES VALUES (48, “WV”, “West Virignia”); INSERT INTO STATES VALUES (49, “WI”, “Wisconsin”); INSERT INTO STATES VALUES (50, “WY”, “Wyoming”);

3. Create and configure the persistence unit
   1. Right-click on the newly created project and select “New”, “Entity Classes from Database …” as shown:

      

   2. In DataSource, select “New Data Source…” and enter the JNDI name “jndi/states” as shown:

      

   3. Select “STATES” table in “Available Tables:” and click on “Add >” and then “Next >”.
   4. Click on “Create Persistence Unit …”, take all the defaults and click on “Create”.
   5. Enter the package name as “server” and click on “Finish”.
   6. Expand “Configuration File”, open “persistence.xml”. Unselect “Include All Entity Classes” check box, click on “Add Class…”, select “server.States” and click on OK. The updated view looks like:

      

   7. Select the XML view and replace <properties/> with
      

      <properties>         <prop erty name=”toplink.jdbc.user” value=”duke”/>         <property name=”toplink.jdbc.password” value=”duke”/>     </properties>

      The username and password values must match the ones specified during database creation. The updated “persistence.xml” looks like:

      <?xml version=”1.0″ encoding=”UTF-8″?> <persistence version=”1.0″ xmlns=”http://java.sun.com/xml/ns/persistence” xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation=”http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd”>   <persistence-unit name=”AutocompletePU” transaction-type=”JTA”>     <jta-data-source>jndi/states</jta-data-source>     <class>server.States</class>     <exclude-unlisted-classes>true</exclude-unlisted-classes>     <properties>       <property name=”toplink.jdbc.user” value=”duke”/>       <property name=”toplink.jdbc.password” value=”duke”/>     </properties>   </persistence-unit> </persistence>

4. Create a Servlet to perform the database operations
   1. Right-click on the project, select “New”, “Servlet”.
   2. Enter the class name as “StatesServlet” and package as “server” and click on “Finish”.
   3. Add the following fragment in the beginning of the class:
      

      EntityManager em;     @Override     public void init() throws ServletException {         EntityManagerFactory emf = Persistence.createEntityManagerFactory(“AutocompletePU”);         em = emf.createEntityManager();     }

      Alternatively, you can use resource injection to populate the EntityManager. Use the following fragment, instead of the above, to achieve that:

      @PersistenceContext(unitName=”AutocompletePU”)     EntityManager em;

   4. Replace the commented code in “processRequest” with the following fragment:
      

      String abbrev = request.getParameter(“abbrev”);             List<States> list = em.createNamedQuery(“States.findByAbbrev”).                     setParameter(“abbrev”, abbrev).                     getResultList();             if (list.size() > 0) {                 States s = list.get(0);                 out.println(“Found ” + s.getName() + ” with abbrev \”" + abbrev + “\”");             } else {                 out.println(“No matching state found with \”" + abbrev + “\”");             }

      and fix the imports by right-clicking in editor pane and selecting “Fix Imports”.

   5. Right-click on the project and select “Undeploy and Deploy”.

Now let’s try it!

Invoking “curl http://localhost:8080/Autocomplete/StatesServlet?abbrev=CA” shows the following output on command prompt:

Found California with abbrev “CA”

Alternatively, you can enter this URL in browser as well to see the output as:

Invoking “http://localhost:8080/Autocomplete/StatesServlet?abbrev=CB” shows the output:

Even though MySQL is used as the database in this case, any other database can be easily used for creating this portable PU.

   ~/testbed/jruby-1.1.3/samples/rails/helloworld >../../../bin/jruby script/generate scaffold runner distance:float minutes:integer JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL       exists  app/models/       exists  app/controllers/       exists  app/helpers/       create  app/views/runners       exists  app/views/layouts/       exists  test/functional/       exists  test/unit/       exists  public/stylesheets/       create  app/views/runners/index.html.erb       create  app/views/runners/show.html.erb       create  app/views/runners/new.html.erb       create  app/views/runners/edit.html.erb       create  app/views/layouts/runners.html.erb       create  public/stylesheets/scaffold.css       create  app/controllers/runners_controller.rb       create  test/functional/runners_controller_test.rb       create  app/helpers/runners_helper.rb        route  map.resources :runners   dependency  model       exists    app/models/       exists    test/unit/       exists    test/fixtures/       create    app/models/runner.rb       create    test/unit/runner_test.rb       create    test/fixtures/runners.yml       create    db/migrate       create    db/migrate/20080721153737_create_runners.rb

6. Start MySQL database, create and migrate the database:
   

   ~/testbed/jruby-1.1.3/samples/rails/helloworld >../../../bin/jruby -S rake db:create (in /Users/arungupta/testbed/jruby-1.1.3/samples/rails/helloworld) ~ /testbed/jruby-1.1.3/samples/rails/helloworld >../../../bin/jruby -S rake db:migrate (in /Users/arungupta/testbed/jruby-1.1.3/samples/rails/helloworld) == 20080721154435 CreateRunners: migrating ==================================== — create_table(:runners)    -> 0.0097s == 20080721154435 CreateRunners: migrated (0.0104s) ===========================

   Now “http://localhost:3000/runners” page is shown as:

   

   After adding couple of entries, the page looks like:

   

   Now, let’s try to run the same application on GlassFish v3 stand-alone build.

   TOTD #33 explains how to build GlassFish v3 workspace. Alternatively nightly or promoted builds can be downloaded as well.

7. Start the v3 server as:
   

   ~/testbed/glassfish/v3/snapshot/glassfish >java -DJRUBY_HOME=/Users/arungupta/testbed/jruby-1.1.3 -jar modules/glassfish-10.0-SNAPSHOT.jar Jul 21, 2008 9:40:41 AM com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on Apache Felix OSGi platform Jul 21, 2008 9:40:41 AM com.sun.enterprise.glassfish.bootstrap.ASMainOSGi getSharedRepos INFO: /Users/arungupta/testbed/glassfish/v3/snapshot/glassfish/domains/domain1/lib does not exist Welcome to Felix. ================= . . .

8. Deploy the application as:
   

   ~/testbed/jruby-1.1.3/samples/rails >~/testbed/glassfish/v3/snapshot/glassfish/bin/asadmin deploy helloworld Command deploy executed successfully.

   and the GlassFish console shows the following output:

   Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.web.war-util [65] Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.persistence.jpa-connector [25] Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.scripting.gf-jruby-connector [13] Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.core.security [22] Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.web.gf-web-connector [86] Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.connectors.gf-connectors-connector [53] Jul 21, 2008 9:47:49 AM com.sun.grizzly.jruby.RailsAdapter startRubyRuntimePool INFO: Starting Rails instances Jul 21, 2008 9:48:01 AM  SEVERE: JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Jul 21, 2008 9:48:02 AM com.sun.grizzly.jruby.RubyObjectPool$1 run INFO: JRuby and Rails instance instantiation took : 12852ms Jul 21, 2008 9:48:02 AM org.glassfish.scripting.rails.RailsDeployer load INFO: Loading application helloworld at /helloworld Jul 21, 2008 9:48:02 AM com.sun.enterprise.v3.deployment.DeployCommand execute INFO: Deployment of helloworld done is 13326 ms

   The deployed application at “http://localhost:8080/helloworld/runners” looks like:

   

Rails powered by the GlassFish Application Server explain in detail about the several benefits of using GlassFish for Rails development and deployment. Rails/GlassFish Deployment Stories gives a good idea of how to structure your own application.
