Hi, I have just installed Apache1.3.14 + modssl + tomcat 3.2b5 on Solaris 2.6 and am trying to call a native method from my servlet (this worked fine under JavaWebServer2.0). The shared library is definitely being loaded (ie no exception is thrown when I tried to load it separately, the lib is on the LD_LIBRARY_PATH etc) but "UnsatisfiedLinkError" is still being thrown indicating the implementation of the native method is not found. I havent done anything special to tomcat for JNI, I was a bit baffled by the purpose jni_server.xml and jni_workers.properties files! I only need to call a C program from within a class called by the servlet, don't need to call java methods from the native code. Has anyone come across anything like this? Many thanks, Mike.
