Hi, I have my beans written in 2.x. I have a project to convert the session beans (stateless) from 2.x to 3.0.
As soon as I put the below line, the compile breaks at this line.
As a result, I cannot use annotation such as: @Stateless in the code. Can someone tell me what am I doing wrong? I am using JBOSS4.0.1sp1 currently with this web application.
Also, how do i find if my
are 2.0 or 2.1?
In the existing code, I do see: ejbCreate(), ejbActivate(), ejbPassivate(), ejbRemove() code used and no annotations used, so I know it is not
Also, in the same JobServiceBean.java file, I do below code:
* @ejb.bean type="Stateless"
* @ejb.env-entry description="The path for middle-tier files."
which is telling me it is Stateless. if I change it to Stateful, the bean becomes Stateful in the resulting (on the fly made) ejb-jar.xml.
Also, when I compile the code, on the fly using xdoclet, the following 4 files are being generated: JobService.java, JobServiceHome.java, JobServiceLocal.java, JobServiceLocalHome.java
Can someone tell me, what kind of bean am I dealing with? (is it remote/local home/localhome)?
I am new to Java, EJB world. I scanned through some documentations about
. Any help would be appreciated. Thanks.

Please look at
4 documentation to see the EJB version supported.
As per their docs, "JBoss AS 4.2 and above supports EJB3 out of the box. Note that JBoss AS 5.0 supports the full EJB3 feature set".
