1. You have to release the ClassLoader that loaded the native library--1.2
states explicitly, in the JNI Spec, that a native library can only be loaded
into one ClassLoader at a time. WHY they do this is beyond me, but it's
hinted that this is a security issue. Check out the JDK1.2 changes to the
JNI Spec, under the "JNI" link off the index.html file in the JDK 1.2
documentation bundle (either downloaded or on javasoft.com).
2. I haven't a clue--are you positive the Vector contains something at the
servlet before it is sent back?
And yes, it's a bit off-topic, but until there's a JNI mailing list, we'll
just growl and make threatening noises at you.... <grin>
Seriously, you might also try the advanced-java list, at "
[EMAIL PROTECTED] " The guys/gals on there might be better
able to assist you with the JNI issues.
