Where to Place .dll files in TOMCAT?
Hi All,
I have a java web application running on TOMCAT 6.0 which is accessing
few .dll files.I am getting "UnsatisfiedLinkError" while running my
application. I have copied these .dll files in System32 folder. Could anyone
please tell me where should i place these .dll files to get my app working.
Please help.
Regards, Sunny

If you are running as a service, using the standard Tomcat wrapper, then you
should place the dll files in the same directory as tomcat6.exe (usually
%CATALINA_HOME%\bin). If you are running from the startup.bat script, then
they need to be somewhere on the %PATH%.
I wouldn't recommend placing dll files in System32 unless absolutely there
is no other option. However, if it isn't working with the dll files in
System32, then you are missing dll files that they depend on in the %PATH%
(aka dll-hell ;).

Martin,
I believe the OP doesn't know what an .so-file is.
I'm also not sure if there's something like "execute-privileges" in Windows.
Besides, he's talking about Tomcat 6, and I can't find anything like a
"shared"-folder in Tomcat 6.
My knowledge about all this library-stuff on MS Windows (btw: Which
version? Vista? XP?) is quite limited, but I believe it's a bad idea
in general just putting this stuff into a system-folder like system32.
If those libraries are called via JNI (which is something I also
dislike), they have to be put into $CATALINA_HOME/lib.
You also have to set the Java-property java.library.path accordingly.
A brief overview can be found here:
http://forums.sun.com/thread.jspa?threadID=780109
Please note that this description is for Tomcat 5 - meaning don't put
them into lib/shared but into lib.
My preferred solution would be to put those dlls int
[your_app/WEB-INF/lib] so that a strict separation from your app-files
and Tomcat is maintained, however, I believe that setting the property
java.library.path within your webapp won't help since the
Tomcat-class-loader might interfere, but I'm not sure about that -
comments on that, anyone?

place jar file in the $TOMCAT_HOME/shared/lib
place the .so in $TOMCAT_HOME/shared/lib
JAVA_OPTS:
java.library.path=$TOMCAT_HOME/shared/lib
and of course ensure $TOMCAT_HOME/shared/lib has execute privileges.
