Hi All,
I have, to the best of my ability, followed the docs on configuring
APR but I am getting "java.lang.UnsatisfiedLinkError" and, so far, not
been able to resolve it. First, some details of my environment :
OS - RHEL 5 x86_64
Java - 1.6.0_29-b11
Tomcat - 6.0.33
Libs - libtcnative 1.1.20
APR - Distro provided 1.2.7
SSL - Distro provided 0.9.8e
I extracted the bundled native tarball located in bin/ and then ran
configure like so -
$ ./configure --with-java-home=/usr/local/jdk/
--prefix=/usr/local/tomcat/ --with-apr=/usr/bin/apr-1-config
--with-ssl=yes
then "make" and "make install" results in the libtcnative shared libs
being installed in tomcat/lib. I then edit tomcat/bin/setenv.sh to
make sure the various environment variables are set correctly so that
it can find the native libraries. My setenv.sh looks like the
following
CATALINA_OPTS="$CATALINA_OPTS
-Djava.library.path=/usr/local/tomcat/lib:/lib64:/usr/lib64"
LD_LIBRARY_PATH=/usr/local/tomcat/lib:/lib64:/usr/lib64
export LD_LIBRARY_PATH CATALINA_OPTS
I then, for debugging purposes start Tomcat from tomcat/bin with
"catalina.sh run" so that I can see the logging directly. It shows the
following
$ ./catalina.sh runlibtcnative-1.so
LD_LIBRARY_PATH = /usr/local/tomcat/lib:/lib:/usr/lib <-- debugging

I am stumped as to why I am getting "UnsatisfiedLinkError" - all
appears to be OK and consistent with what the install guides
recommend. Additionally, ldd does not show any missing dependencies
for libtcnative-1.so -
