Hi John,
I'm getting very confused about this. I tell you what I did.
To check the Jonas problem of null Classloader I simply wrote a few lines like this:
public class TestCL(){
public TestCL(){
System.out.println("this.getClass().getClassLoader()="+this.getClass.getClassLoader());
}
public static void main(String [] argv)
{
new TestCL();
}
}
the result are
java TestCL --> not null
java -Xbootclasspath/a:TestCL.class --> null
(this seems right according to SUN docs)
as a service (with a nt service installer we wrote) --> null
note that as a service The classpath is passed to JNI_CreateJVM(...) function as:
-cp Test.class
so it should be equivalent to the command line switch (even tried putting in the
CLASSPATH env var)
The same problem, I guess is in Jonas
In class org.objectweb.jonas_ejb.deployment.api.DeploymentDesc
we have:
(line 219)
ClassLoader cl = DeploymentDesc.class.getClassLoader()
which is passed to the singleton constructor.
Don't know how to solve the problem.
Thanks,
Vincenzo

A voice cackles in Calvin's radio:
