Hey Guys,
Well ... I did the JNI interfacting with an Entity bean using Weblogic 5.1 .
It does it ..... But theres no proper documentation for it .. so i had to do
the rnd myself...
You could declare the JNI methods as native in yr Entity Bean.
Use System.loadLibrary to load the dll in yr Entity Bean Class
And in the C++ code do not forget to give the COMPLETE and i repeat the
Complete path of yr Entity bean Class(include the package too).
Should you have any questions ... do not hesitate to mail me.
Regds,
Samir Mathur

Likewise, our AppServer supports JNI. That being said, I
STRONGLY recommend using CORBA to integrate native code
into your EJB application. Having developed quite a bit
of JNI code (and mountains of CORBA code) I can easily
vouch for the fact that integrating C or C++ code using
CORBA is substantially easier than using JNI.
