TOTD #99: Creating a Java EE 6 application using MySQL, JPA 2.0 and Servlet 3.0 with GlassFish Tools Bundle for Eclipse

TOTD #97 showed how to install GlassFish Tools Bundle for Eclipse 1.1. Basically there are two options - either install Eclipse 3.4.2 with WTP and pre-bundled/configured with GlassFish v2/v3, MySQL JDBC driver and other features. Or if you are using Eclipse 3.5, then you can install the plug-in separately and get most of the functionality.

TOTD #98 showed how to create a simple Metro/JAX-WS compliant Web service using that bundle and deploy on GlassFish.

This Tip Of The Day (TOTD) shows how to create a simple Java EE 6 application that reads data from a MySQL database using JPA 2.0 and Servlet 3.0 and display the results. A more formal support of Java EE 6/Servlet 3.0 is coming but in the meanwhile the approach mentioned below will work.

Lets get started!

1. Configure database connection - The key point to notice here is that the MySQL Connector/J driver is already built into the tool so there is no need to configure it explicitly.
   1. From "Window", "Show Perspective", change to the database perspective as shown below:
      
      
   2. In the "Data Source Explorer", right-click and click on "Database Connections" and select "New ...":
      
      
   3. Search for "mysql" and type the database name as "sakila":
      
      
      
      This blog uses MySQL sample database sakila. So please download and install the sample database before proceeding further.
   4. Click on "Next >" and specify the database configuration:
      
      
      
      Notice the "Drivers" indicate that the JDBC driver is pre-bundled so there is no extra configuration required. If you are using a stand-alone Eclipse bunde and installing the plugin separately, then you need to configure the MySQL JDBC driver explictily.
      
      The URL indicates the application is connecting to the sakila database. Click on "Test Connection" to test connection with the database and see the output as:
      
      
      
      and click on "Finish" to complete. The expanded database in the explorer looks like:
      
      
      
      The expanded view shows all the tables in the database.
2. Create the Web project & configure JPA
   1. Switch to JavaEE perspective by clicking "Window", "Choose Perspective", "Other ..." and choosing "Java EE".
   2. Create a new dynamic web project with the following settings:
      
      
      
      Only the project name needs to be specified and everything else is default. Notice the target runtime indicates that this is a Java EE 6 application. Click on "Finish".
   3. Right-click on the project, search for "facets" and enable "Java Persistence" as shown below:
      
      
   4. Click on "Further configuration available ..." and modify the facet as shown below:
      
      
      
      Make sure to disable "orm.xml" since we are generating a standard Java EE 6 web application. Choose "sakila" as the database. Click on "OK" and again on "OK" to complete the dialog.
3. Generate the JPA entities
   1. Right-click on the project, select "JPA Tools", "Generate Entities" as shown:
      
      
   2. Choose the schema "sakila":
      
      
      
      and click on "Next >". If no values are shown in the schema drop-down, then click on "Reconnect ...".
   3. Specify a package name for the generated entities as "model" and select "film" and "language" table:
      
      
      
      and click on "Finish". The "film" and "language" table are related so it would be nice if all the related tables can be identified and picked accordingly.
      
      Anyway this generates "model.Film" and "model.Language" classes and "persistence.xml" as shown below:
      
      
      
      Also notice that "web.xml" and "sun-web.xml" have been explicitly removed since they are not required by a Java EE 6 application.
   4. "model.Film" class needs to modified slightly because one of the columns is mapped to "Object" which is not a Serializable obect. So change the type of "specialFeatures" from Object to String and also change the corresponding getters/setters accordingly. The error message clearly conveyed during the initial deployment and so could be fixed. But it would be nice to generate the classes that will work out-of-the-box.
4. Create a Servlet client to retrieve/display data from the database
   1. Right-click on the project, select "New", "Class" and specify the values as:
      
      
      
      and click on "Finish". This class will be our Servlet client.
   2. Change the class such that it looks like:
      

      @WebServlet(urlPatterns="/ServletClient")
      public class ServletClient extends HttpServlet {
        @PersistenceUnit
        EntityManagerFactory factory;
      
        protected void doGet(HttpServletRequest req, HttpServletResponse resp)
               throws ServletException, IOException {
          ServletOutputStream out = resp.getOutputStream();
          List list = factory.createEntityManager().createQuery("select f from Film f where f.title like 'GL%';").getResultList();
          out.println("<html><table>");
          for (Object film : list) {
            out.print("<tr><td>" + ((Film)film).getTitle() + "</tr></td>");
          }
          out.println("</table></html>");
        }
      }
      

      
      and the imports as:
      

      import java.io.IOException;
      import java.util.List;
      
      import javax.persistence.EntityManagerFactory;
      import javax.persistence.PersistenceUnit;
      import javax.servlet.ServletException;
      import javax.servlet.ServletOutputStream;
      import javax.servlet.annotation.WebServlet;
      import javax.servlet.http.HttpServlet;
      import javax.servlet.http.HttpServletRequest;
      import javax.servlet.http.HttpServletResponse;
      
      import model.Film;
      
      

      Basically, this is a Servlet 3.0 specification compliant Servlet that uses @WebServlet annotation. It uses @PersistenceUnit to inject the generated JPA Persistence Unit which is then used to query the database. The database query return all the movies whose title start with "GL" and the response is displayed in an HTML formatted table.
   3. Right-click on the project and select "Run As", "Run on Server" and select GlassFish v3 latest promoted build (this blog used build 61) as:
      
      
      
      and click on "Finish". The output at "http://localhost:8080/HelloJPA/ServletClient" looks like:
      
      

Simple, easy and clean!

TOTD #98: Create a Metro JAX-WS Web service using GlassFish Tools Bundle for Eclipse

Now that you've installed GlassFish Tools Bundle for Eclipse 1.1, lets use this bundle to create a simple Metro/JAX-WS compliant Web service and deploy on GlassFish. These steps will work with either Eclipse 3.4.2 or 3.5 with WTP Java EE support.

1. Lets create a simple "Dynamic Web Project" as shown below:
   
   
   
2. Name the project "HelloMetro" and take all other defaults:
   
   
   
   Click on "Finish" to complete the project creation.
3. Metro allows to create a Web service from a POJO class. So let's add a POJO to the project by right-clicking on the project and selecting "New", "Class" as shown below:
   
     
   
   Specify the package name as "server", class name as "HelloService" and click on "Finish".
4. Add a simple method to the newly generated class as:
   
   

   public String sayHello(String name) {
         return "Hello " + name + "!!";
   
   }
   

5. Expand the project, go to "HelloService.java" in "server" package, right-click, select "Web Services", "Create Web service".
6. Click on "Web service runtime: Apache Axis" and select "Metro (JAX-WS) Runtime" as the Web service runtime as shown below:
   
   
7. Move the slider on the left to top. This will enable testing of the deployed Web service. The completed configuration looks like:
   
   
   
   and click on "Next >".
8. Select the checkbox "Copy Metro library jars to the project" to resolve the references correctly as shown below:
   
   
   
   and click on "Next >". This bundles the application and deploys to GlassFish and provides an option to test the deployed Web service as shown below:
   
   
   
   Clicking on the "Launch" button shows the following output in the browser:
   
   
   
   The WSDL is hosted at "http://localhost:8083/HelloMetro/HelloServiceService?wsdl".
9. Click on "sayHello" method, click on "Add" and enter the value as "Duke" as shown below:
   
   
   
   Click on "Go" and the response is shown as:
   
   
   
   Clicking on "Source" in the response window shows the SOAP request/response messages as shown below:
   
   
10. Alternatively, you can click on "Finish" to complete the dialog. Then click on "Run" menu item, "Launch the Web Services Explorer" to see a screen as:
    
    
    
    Enter the URL of the WSDL in "WSDL URL" box as "http://localhost:8083/HelloMetro/HelloServiceService?wsdl" and click on "Go". Now you are seeing the similar screen to test the Web service within the integrated browser as shown below:
