IBM/LANDP classes and J++ 1.1

I need to write a Java application using Microsoft J++ 1.1 under Windows NT 4.0. In this application (a LANDP-Server) I have to call some 'third-party' classes that need a special DLL in the System directory. The application compiles without any problems, but when i start it using JVIEW, I get the following error message:

"Could not load LANDP/JAVA for Windows NT DLL java.lang.UnsatisfiedLinkError: ldpjnt.dll cannot
load because RNIGetCompatibleVersion export not found (new behavior.)"

The ldpjnt.dll comes with the third-party classes, so I do not have any influence on it.

I hope someone can help me with this.
