Title: Standalone Client, ClassNotFound problem

Hi Erich,

 

It could not instantiate the class UIBrowserService (which is in ulc-base-client.jar) because it could not find it.

 

How did you set up the ULC client to use the URLClassLoader?

 

ULC client uses Thread.currentThread().getContextClassLoader() for loading classes if it is not null else it uses the default class loader used to load ULC UI classes.

 

I hope this helps.

 

Thanks and regards,

 

Janak

Hello

I try to launch our application as Standalone Client. If I add all the required jar's to the CLASSPATH then it works fine. But if I setup an URL Classloader and set it up so that it uses the same jars I get the following Exception.

Unfortunatly it only says "Got ClassNotFoundException", it would be interesting to know which one it's missing.
I'm using ULC6.1.1, with earlier versions (6.0.x) I did not have this problem!
