For sometime, I've been encountering an error in my JAX-WS application in Maven when deploying it to Websphere. The error occurs when your web service's return type is a List. Here's the exact error:
[javax.xml.bind.JAXBException: java.util.List is not known to this context]
Exporting the war file using IBM RAD will not let you encounter this problem. Unfortunately, RAD does not have a Maven plugin so we are using the native Eclipse IDE. So we've come up to a solution using the jaxws-maven-plugin to make sure the application will run properly in Websphere. Add this into your pom.xml :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>compile</goal>
</goals>
</execution>
</executions>
<configuration>
<target>1.6</target>
<source>1.6</source>
</configuration>
</plugin>
<plugin>
<groupid>org.codehaus.mojo</groupId>
<artifactid>jaxws-maven-plugin</artifactId>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>wsgen</goal>
</goals>
</execution>
</executions>
<configuration>
<destdir>src/main/java</destDir>
<sei>ph.com.src.endpoint.WsEndpoint</sei>
<keep>true</keep>
<verbose>true</verbose>
</configuration>
</plugin>
The <sei> should be the location & name of your service endpoint interface. It will I think sort of override it so that no error will occur. :)
