Maven 2 EJB 3.0

[Bhiku Mhatre]

I am trying to compile a ejb 3 project using maven2. However, I am running into following issue.

[40,1] annotations are not supportedin -source 1.3
(try -source 1.5 to enable annotations)
@MessageDriven(mappedName = "jms/mymsgbean", activationConfig =


The project structure is
parentProj
ejbpoj1
ejbpoj2
ejbpoj3


Here is the parentproj.pom file.

<project>

Does anyone have a solution?
Important input: JAVA_HOME point to JDK 5.0

Thanks,

Is this happening to beans in all your sub-projects or just one? Is there anything in the sub-project POMs that could override the setting? Or any system/user settings that could override this?

[Bhiku Mhatre]

I resolved the problem. The issue arised due to faulty inheritance. Now that inheritance is set properly, it is working.

Thanks Natan for looking into the problem.

[Bhiku Mhatre]

Hmmm. Looks like I reported the success prematurely. The EJB 3.0 problem still persists.

Here is my pom.xml

<project>
<modelVersion>4.0.0</modelVersion>

<parent>
<groupId>com.acme</groupId>
<artifactId>ejbs</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>

<artifactId>abcdMassageBean</artifactId>
<packaging>ejb3</packaging>
<name>abcdMassageBean</name>

</project>
upon trying compile target, following error is thrown.


Please note: When packaging is set to ejb, it works fine.

The maven-ejb-plugin page gives this plugin configuration for building to the EJB3 spec -

  <build>
    ...
    <plugins>
      ...
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-ejb-plugin</artifactId>
        <configuration>
          <ejbVersion>3.0</ejbVersion>
        </configuration>
      </plugin>
    </plugins>
  </build>

So you would leave packaging as 'ejb' and the above configuration should make your EJB 3.0 spec.

Nathan,
Thanks for quick reply. I tried and it worked. I was refering to documents on Maven forum which it appears are obsolete. I am very close to packaging an ear file. However, another error is thrown in the following script of ear generation project.


Here is pom.xml

Thanks once again for your help.

[Bhiku Mhatre]

Resolved the issue by stating ejbModule instead of ejb3Module and type to be ejb instaed of jar. Please note, with these changes, Still, ejb3 files are inclueded.
The question is, when is one suppoesed to use ejb3Module Tag? It appears to be redundant and misleading tag.

Thanks.
