Hi, I encountered an error when my application tries to load a RSA Algorithm provider class from JAVA. The exception stack is as follow:

I've googled the error message and most of posts says it's because JVM cannot find sunjce_provider.jar. However, I can find the file in /Library/Java/Home/lib/ext folder.

The platform is Mac OS X 10.6 and Java version is 1.6.0_17.

My questions are:

1. Why JVM does not search /Library/Java/Home/lib/ext for jar files?
2. Can we change CLASSPATH or java.ext.dirs property by modify any config file?
3. Any suggestion to solve this problem?

Thanks in advance.
