I'm getting this on HEAD and Branch_3_0 when I try to call a method (not
a CMP accessor) on a simple CMP bean I have (enclosed) deployed with no
problems.
The Bean is meant to be a simple example of how to plug a persistent
layer into my new pluggable HttpSessionManager for Jetty/JBoss. The
trouble is, because of this, it does not work !
Is this a JBoss problem, or is my bean rubbish - If my bean is rubbish
could we have a more helpful exception?
Cheers,
Jules
P.S.
All dds are generated by xdoclet from the Bean's src.
I run xdoclet from Ant thus:
<ejbdoclet
sourcepath="${top.dir}/src"
destdir="${top.dir}/output/ejb/src"
ejbspec="2.0"
excludedtags="@version,@author"
classpath="./src:./output/ejb:./lib/jboss-j2ee.jar:./lib/xdoclet.jar:lib/ant.jar:lib/log4j.jar"
>
<fileset dir="${top.dir}/src">
<include name="**/session/ejb/*Bean.java" />
</fileset>
<packageSubstitution packages="ejb" substituteWith="interfaces"/>
<!--

<jboss version="3.0"

typemapping="Hypersonic SQL"

destdir="${top.dir}/output/ejb/META-INF"
/>
</ejbdoclet>
<!-- build ejb classes -->
<javac

debug="${debug}"
>
<classpath refid="ejb-classpath" />
<include name="**/session/ejb/*.java" />
<include name="**/session/interfaces/*.java" />
</javac>
</target>
P.P.S.
Feel free to abuse me - I know very little about EJBs....
