I am using Proxygen to generate proxies for a jar and have the following problem:

C:\Program Files (x86)\IAI\CLAT\wdclint\lib>proxygen.exe clapi.jar
jni4net.proxygen - Copyright (C) 2009 Pavel Savara - licensed under GPLv3
Can't load class org/apache/log4j/net/JMSSink
Can't load class org/jdom2/xpath/jaxen/JDOM2Navigator
Can't load class org/jdom2/xpath/jaxen/JDOMCoreNavigator
Can't load class org/jdom2/xpath/jaxen/JDOMNavigator
Can't load class org/jdom2/xpath/jaxen/JaxenCompiled

java.lang.NoClassDefFoundError: javax/help/HelpSetException

However, as the screenshot shows, the classes are there. (JMSSink is at the right place, too.)

Can someone give me a hint what I could do to solve this?
Thank you!

Best regards,

Hi Koch,
Did you append to solve this issue?
Unfortunately I have the same and didn't mange to find out why. or any useful information in the web or at

JAR with Classes are current in CP, I also try to set all files at the same place - nothing seems to work.

Process and with something like this:
Can't load class com/my/require/class/name1
Can't load class com/my/require/class/name2
Can't load class com/my/require/class/name3

will generate CLR
will generate CLR
will generate CLR
and than
proxygen done

But my require classes are not there.

Any tip will be more than welcome.
