Jerome, what I found out was that the java.library.path property is a 1.2 specific
property. As I was using the IBM JDK 1.1.18 it did not help. I then switched to the
Blackdown 1.2 pre-v2 JDK and it did help. But only the first time the servlet was
run. In order to run the servlet successfully one must shut Apache down and restart
it each time.
Obviously this is not acceptable.
The problem has something to do (IMHO) with the implementation of the Apache
"adaptable" classloader. If I circumvent this classloader by splitting up the code
into 2 JAR's and put them in the wrapper.classpath things seem to work better. My
understanding is that doing this allows the JDK to use the "system" classloader
rather than the Apache-Jserv classloader. I could be all wet here but it does seem
to help. The 2 JARs' contents are:
1st JAR: class that loads the JNI library;
2nd JAR: everything that is 100% Java (some classes use the class in the 1st JAR)
I am still looking for a "real" solution. I will let you know if I find out
anything.
