How I managed to run a standalone Oracle SOA Suite Worklist basic client

Escenary:

• Standalone command line remote client.
• No IDE.
• Basic client funcion: print all tasks for a hard-coded user.
• Based on "Invoking BPEL Worklist API from Remote Server with Java [Amis blog]" and buddy's help.
• I ran it on Java 1.4. It's not working on Java 5 for me. Java says: "java.lang.SecurityException: class "com.collaxa.cube.ExceptionIndex"'s signer information does not match signer information of other classes in the same package". But works also on Java 6. Ups.
