I'm trying to create a Web Bundle for a sample GWT application.
I am using the GWT plugin to generate the test application and added EclipseRT Virgo Server Facets to the project. The basic structure of the project was as follows:

br.teste.web.gwt
| __src
   | __ Br.teste.gwt
      | __ ...
| __war
   | __WEB-INF
      | __web.xml
      | __lib
         | __gwt-servlet.jar
   | __META-INF
      | __MANIFEST.MF

MANIFEST.MF

Manifest-Version: 1.0
Class-Path:
Bundle-Version: 1.0.0
Bundle-Name: TesteGWT
Bundle-ManifestVersion: 2
Web-contextPath: webtest
Bundle-SymbolicName: br.teste.gwt

If I compile the project and run directly by GWT it works, but if I deploy directly in VIRGO TOMCAT Server the application loads but clicking on the button an RPC call fails with ClassNotFoundException

java.lang.ClassNotFoundException: br.teste.gwt.server.GreetingServiceImpl
org.eclipse.gemini.web.tomcat.internal.loading.BundleWebappClassLoader.loadClass(BundleWebappClassLoader.java:306)
java.lang.ClassLoader.loadClass (Unknown Source)

I understand that my WAB is not with the classes in classpath.

Any help?

Try importing the missing package(s) in your manifest.

Have you installed a bundle which exports the package br.teste.gwt.server?

Hi Glyn,
No because my teste app has only this bundle.
This test application is self contained and all that is needed is inside the bundle.
This is possible right?

The class br.teste.gwt.server.GreetingServiceImpl is in WEB-INF/classes

Add the location of your classes to Bundle-ClassPath in the manifest. In your case this should be . and WEB-INF/classes I guess.

Add the Bundle-ClassPath in the manifest did the trick Smile

But I had to add each classpath entry one by one, which in a large application can be a pretty boring.
I thought that for a WAB Bundle the OSGI container import the contents of the WEB-INF/classes and WEB-INF/libs into the classpath.

Manifest-Version: 1.0
Class-Path: 
Bundle-Version: 1.0.0
Bundle-Name: TesteGWT
Bundle-ManifestVersion: 2
Web-ContextPath: webtest
Bundle-SymbolicName: br.teste.gwt
Bundle-ClassPath: /WEB-INF/classes, /WEB-INF/lib, /WEB-INF, ., WEB-INF/lib/gwt-servlet.jar
Import-Package: javax.servlet;version="[3.0.0,3.0.0]",
 javax.servlet.http;version="[3.0.0,3.0.0]"

Thanks Frieder and Glyn for the help!
