Tomcat classloader and JNI questions
I am working on getting Jmagick to work with Tomcat-4.1 and JDK 1.4. I have heard that it is possible but no one can quite describe how so I've been doing some experimentation with it. It does work if I use this command to start Tomcat: # LD_LIBRARY_PATH=/usr/local/lib java -Djava.endorsed.dirs= -classpath /usr/java/j2sdk1.4.0_01/lib/tools.jar:/var/tomcat4/bin/bootstrap.jar -Dcatalina.base=/var/tomcat4 -Dcatalina.home=/var/tomcat4 -Djava.io.tmpdir=/var/tomcat4/temp org.apache.catalina.startup.Bootstrap start where of course the .so file is in /usr/local/lib. So, I have two questions related to this: First, why should LD_LIBRARY_PATH be necessary? I am doing this under Linux, and I put /usr/local/lib in /etc/ld.conf, and reran ldconfig, so I shouldn't need to set the LD_LIBRARY_PATH. But if it is necessary, is there some way to modify the startup scripts to take care of this, so I can use them instead of having to start java directly from the command line? Second, it does not make sense to me that I have to include the jmagick.jar in the classpath in the command line. Tomcat's classloader has many options and places to put things, but I tried putting the jar in CATALINA_HOME/lib, CATALINA_HOME/common/lib, and WEB-INF/lib, and it does not work in any of those cases. The only way to get jmagick to work is to add it to the command line classpath. Is there any other way, and if not, is there a way to modify the standard startup scripts so that they include it, so I don't have to run java directly? Thanks! After I get this all figured out I'm going to write it up and post it. The good news is that Jmagick does definitely work with Tomcat and JDK 1.4; the bad news is that it's not documented how to do this, so I'll change that. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

The ONLY way to get the JVM to load the shared libs is if the jmagick.jar is in the classpath itself. Would this be considered a Tomcat bug, or is this just the way it is with JDK 1.4? If this is the only way to do this, there should probably be an extra config files for adding more jars to the JVM's own classpath.

RE: Tomcat classloader and JNI questions
put it in /common/lib and restart tomcat so that it sees it. Tomcat completely ignores the classpath, so I'm not sure how that made a difference here.
