getting line numbers instead of (compiled code)

[Christoph Kukulies]

I dug out an old example I wrote some time ago
and I'm wondering why I'm suddenly getting a Nullpointer Exception:

/servlets/servlet/Auftr_Baustein

Kuku's RMIJDBC Access Demo

Error: 500

Location: /servlets/servlet/Auftr_Baustein

Internal Servlet Error:

java.lang.NullPointerException
        at Auftr_Baustein.doGet(Compiled Code)
        at javax.servlet.http.HttpServlet.service(Compiled Code)
        at javax.servlet.http.HttpServlet.service(Compiled Code)
        at org.apache.tomcat.core.ServletWrapper.handleRequest(Compiled Code)
        at org.apache.tomcat.core.ServletWrapper.handleRequest(Compiled Code)
        at org.apache.tomcat.servlets.InvokerServlet.service(Compiled Code)
        at javax.servlet.http.HttpServlet.service(Compiled Code)
        at org.apache.tomcat.core.ServletWrapper.handleRequest(Compiled Code)
        at org.apache.tomcat.core.ContextManager.service(Compiled Code)
        at 
org.apache.tomcat.service.connector.Ajp12ConnectionHandler.processConnection(Compiled 
Code)
        at org.apache.tomcat.service.TcpConnectionThread.run(Compiled Code)
        at java.lang.Thread.run(Compiled Code)


I cannot remember when my example ran last time and whether it
was before I introduced tomcat as the servlet executor.

Anyone I gotta live with the current
configuration and have to get my examples running again.

Where should I look for? Could it be a security policy
problem that I'm trying to open a socket via rmijdbc?
Could a .jar file be missing? How can I traceback the error into my code?

Help!
