Hi guys!
I was able to reach JNDI-Namespace and EJBs in WebSphere with a TestProgramm. It was a simple class, that tries to access it.
WebSphere ships some batch-files to start Clients, that want access WebSphere-JNDI. These batches call a com.ibm...WSLauncher class, that calls the "own class" (my TestProgramm) by invokation.
I tried the same with Tomcat and edited the batches accordingly. I found out, that WSLauncher uses his own Classloader. AND TomCat uses his ownt too. Furthermore TomCat ignores some system-properties (like classpath, if set).
The occurring problem is, that the com.ibm....InitialFactory cant be instanciated (cause TomCat Classloader tries to, but only WS-Classloader is able to). (By the way - imho its imossible to reach WS-JNDI via another CtxFactory than the one from WS itself)
Just for people who are interressted :-)
Anyway - each suggestion would be welcome ^^
