I'm not sure what OS X uses, but on unix it is the LD_LIBRARY_PATH, or on Windows the PATH. Try and get the code to output the environment before it does the load library call and make sure that the locations for all the dependant libraries are there.

I tried setting java.library.path before, but when setting LD_LIBRARY_PATH and DYLD_LIBRARY_PATH (Mac OS X/Darwin) it seems to work!! :-) However, it only works when I'm running Tomcat from the startup script from command line. When I try to start Tomcat from Eclipse plugin, it still doesn't find the library =( Which makes it harder to debug... Anyone familiar with setting library paths to be found from Eclipse/Tomcat plugin?? TIA, Josef - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
