JNI Library can only be called once from statefull session bean

[Former Member]

Hello,

I have deployed a stateful session bean, that call a C++ Library. The library path is added to LD_LIBRARY_PATH, and the first time I call this method, it works just fine, but if I try to recall the same method again, I received a java.lang.UnsatisfiedLinkError.

I tried to redeploy the app, but nothing. It's only if I restart the application Server, that the first call succeed.

Have any of you seen this behavior before ?

Regards.

Hello,

Thank you!

I guess that my problem was indeed that my library might be loaded more than once, in 2 places.

Hello,

had the same problem with self developed jni library. the problem i had was that the libray got loaded every time i called a method (causing a unsatisfiedLinkError when calling the method more than once).

maybe your are loading your library every time you use the bean with system.loadlibrary? loading the library once could be achieved inside a static constructor for example

Hi Thierry,

Check your classpath I think it is not being set.

Also try to give your class path in the environment variable in your system settings.
