Resource Sharing

[ew...@vividsolutions.com]

Hi all, 

I have an application that uses a JNI to a .dll file. I have since started
another application that I want to use the same .dll file but when I try to
run it I get the following error:

Exception Report:
Cannot allocate servlet instance for path
/mapstats/servlet/webade.sample.mapstas.MainServlet

Root Cause:
java.lang.UnsatisfiedLinkError: Native Library
C:\WINNT\system32\JWindows.dll already loaded in another classloader

I guess what I am wanting to know is, how I can get these two apps
to play nice together and share the .dll?

Thanks

To make sure that your native code can be used from more than one web app,
you will need to ensure that it is loaded by a class that is also shared
across web apps.  The easiest way to do that is to put the class in a JAR
file under the "lib" directory.
