Hi
I am having some trouble configuring a web application on Tomcat 6.0.14 that
is calling native
libs via JNI on Red Hat Ent 3.0.
I have not been able to configure it successfully and I am running out of
ideas.
I get errors like this
java.lang.UnsatisfiedLinkError: Native Library WEB-INF/lib/libfoo.so
already loaded in another classloader
at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1525)
And also ClassNotFound, also if I run everything from a standalone app it
works fine.
What discovered so far is this:
http://wiki.apache.org/tomcat/HowTo#head-a4b7185ee95d0cf14a48f92c08d1eb66b561139d
"one cannot place the native libraries OR their JNI interfaces under the
WEB-INF/lib or WEB-INF/classes directories "
"both this class and the shared library should be placed in the
$CATALINA_HOME/shared/lib directory."
Actually $CATALINA_HOME/shared/lib directory doesn't exist on my
installation so I created it and as test
I created and placed a dummy javalibrary in a .jar file in this location. I
created a dummy WebApplication
and included this library via the netbeans IDE and instanciated the library
class within the WebApps Serlet.
I noticed when I build the project with netbeans it copied and included the
java library into the WebApps .war
file (in the WEB-INF/lib directory structure which is not allowed for JNI
apps) . So I removed this before putting
the .war file into the Tomcats WebApps directory.
I have tried both setting AND not setting the CLASSPATH env variable but
according to
http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html
Tomcat ignores CLASSPATH anyway.
Does anyone have any ideas ?
Thanks
