Problems running JNI code inside Tomcat 5.0.28

[Joe Krause <JK...@multivisioninc.com>]

Hey Folks,

We have a C++ SDK that we HAVE to integrate using JNI. We are able to
create a console Java app that works perfectly (and beautifully) using
JNI and our C++ SDK. When we wrap this up in servlets and attempt to run
it within Tomcat 5.0.28, we get an UnsatisfiedLinkError:

java.lang.UnsatisfiedLinkError: nativeMethod
	com.mv.jni.MyNewString.nativeMethod(Native Method)
	com.mv.jni.MyNewString.test(MyNewString.java:6)
	com.mv.HelloWorldExample.doGet(HelloWorldExample.java:46)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:697)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:810)

The stack trace above is actually from a highly oversimplified "Hello
World" prototype example (which also works in its console app form but
not servlet form). We have checked and doubled checked everything -
static initializer for the *.dll (did I forget to mention this is in
Windows?) and the -Djava.library.path=C:\tomcat\shared\lib. 

There must be something we are overlooking which will get this to work
within Tomcat. Does Tomcat prevent native code from being loaded or
accessed? Has anyone run across this problem before or know how to fix
it? Any tutorials???

Thanks

Joe
