Creating and Invoking a Web service using GlassFish in NetBeans, IntelliJ, and Eclipse - Part 2

In this second part of a blog series (part
1), I plan to explore the steps to develop/deploy/invoke a Web service
on GlassFish using IntelliJIDEA
IDE.

Searching in the help bundled with the IDE on "web service from Java" returned
no results relevant to Web service. I found several (1,2,3)
people asking "How do I develop Web service in IntelliJ 6.x?" but all
the questions are unanswered. The online
documentation does not seem to talk anything about Web service. Searching
on intellij.org gave no results. Finally I found some lead
after searching in the forums but there is no help on "Enable Web Service
Support" as mentioned in the post. Another response
in the forum requires you to add @javax.jws.WebService manually, pretty primitive. So
I decided to ask the question (1,
2) in
the forum. 

After discussion in the forum I found that IntelliJ does not support creation
of Web services natively but instead support it through a Web
service plugin. The plugin, at the time of this writing is "0.6 build
2" with few skeptical comments but anyway worth a try. This plugin supports

JWSDP 2.0 so first I'll investigate how Web services can be deployed on GlassFish and then come back to this plugin.

Here are the steps I followed to successfully build and deploy a Web service:

1. Create a Web module (requires 12 clicks for default settings), say with
   name "hello". On Deployment Descriptors tab, select the default
   "Web Module Deployment Descriptor" and delete it as shown
   here. This is not required for deploying a Web service in GlassFish v2.
   Take all other defaults.
2. In the "Project" pane, click on "src", add a new
   package "hello" as shown
   here.
3. Select the package "hello", add a new class "Hello" as
   shown
   here.
4. Click on the Project, right-click and select "Module Settings".
   Select the module and remove "j2ee.jar" as shown
   here. Add a new module library, javaee.jar, from GlassFish lib
   directory as shown
   here.
5. Add @javax.jws.WebService annotation to the class and add a
   method as shown:
   
   
   
   

   @WebService<br>
       public class Hello {<br>
       &nbsp; public String sayHello(String name) {<br>
       &nbsp;&nbsp;&nbsp; return "Hello " + name;<br>
       &nbsp; }<br>
       }

6. Select "Build", "Make Project" (default shortcut
   Ctrl+F9).
7. Configure and Run GlassFish v2 in IntelliJ. I
   added GlassFish
   v2 M4 using the following steps.
   1. Select "Run", "Edit Configurations ..." menu.
   2. Click on "+" in top-left corner to add a new configuration and
      then select "GlassFish Server" and "Local" as shown
      here.
   3. Specify the location of GlassFish by clicking on "Configure"
      button.
   4. Select the domain (default value "domain1") in "GlassFish
      Server Settings".
   5. Add a new server by clicking on "+" in top-left corner and give
      the location where GlassFish is installed as shown
      here. Ignore the "There are no modules to deploy" warning
      as this will be fixed during Run. Now GlassFish is configured.
   6. To run the GlassFish instance
      1. Select
         "Run", "Run" (default shortcut
         Shift+F10) menu item. 
      2. Run configuration window displays the
         warning message "There are no modules to deploy". Go to
         "Deployment" tab and selecting the newly created module to deploy
         as shown here .
      3. Check "Deploy Web Module" check box and click
         "Configure" button and select "Create web module war
         file". A warning is displayed "Warning: 'Glassfish Web
         Module Deployment Descriptor' is not defined" as shown
         here. This message can be ignored as no GlassFish specific
         deployment descriptors are required.
      4. Click "Run" button.
8. Once the GlassFish server has started, the endpoint is hosted at http://localhost:8080/hello/HelloService?wsdl.

The key point to note here is that no Deployment Descriptors (either standard
or application serve specific) are required in the WAR file. The deployed WAR
file in GlassFish consists only of the compiled class. 

The only way IDEA support creation of Web service clients is through Web
Services plugin so I'll explore it in another blog. So the recommended way is to use NetBeans
5.5.1 to invoke
the Web service.

Enjoy Web services deployed on GlassFish
in IntelliJIDEA! And remember, GlassFish v2 uses Web
Services Interoperability Technology (WSIT) that gives you interoperable Web
services with Microsoft .NET 3.0 framework.
