Sorry, no old jboss.jar (or other old jBoss jars around).
I already checked this, and now I have re-checked, re-re-checked
and checked an extra time just to be sure.
I'm pretty new to all this classloader stuff, but after some
debugging I think I know what happens:
1) In the ejb-jar.xml file for the Nextgen BMP Bean (in file
src/deploy/TestBeans.jar), we have a resource reference:
<resource-ref>
<description>A jdbc connection for the BMP bean</description>
<res-ref-name>jdbc/myDatabase</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
2) I don't think that this datasource is resolved anywhere, so
a default datasource should be used.
3) In org.jboss.ejb.Container.setupEnvironment(), the bean
environment (including resource bindings) is set up.
4) If the reference has not been resolved, and it refers to
a javax.sql.DataSource, a default datasource must be found.
5) Default datasource is found as follows: Iterate over the
JNDI initial context, and try to load every class name found
here to see if the loaded class is assignment compatible
with DataSource.
6) The three classes that i have problems with seem to
be listed in JNDI, but cannot be loaded by the classloader.
7) The exception stack is:
java.lang.ClassNotFoundException: class
org.jboss.security.EJBSecurityManagerDefaultImpl
at javax.management.loading.MLet.findClass(MLet.java:641)
at java.lang.ClassLoader.loadClass(ClassLoader.java:297)
at java.lang.ClassLoader.loadClass(ClassLoader.java:253)
at org.jboss.ejb.Container.setupEnvironment ...
I think the problem is with 5) above, and that we should try
something smarter to get a default datasource.
Anybody know where to get the JMX RI source ?
It a bit annoying not knowing what MLet.java does at line
641, and the JMX RI docs doesn't say much.
