tomcat, native apr connector under linux, problem - WTF?

[Maciej Mrozowski]

hi
I've got the following (common I guess) problem when starting tomcat (under
eclipse):

<console_output>
2006-06-05 19:50:26 org.apache.catalina.core.AprLifecycleListener

I've compiled native connector from the source (taken from
tomcat/bin/some_tar_gz), and put it in $CATALINA_HOME/lib. Then I followed
instructions (there's readme shipped with source code) and added connector
to $CATALINA_HOME/conf/server.xml:


<Connector port="9010" enableLookups="false" redirectPort="9443"
protocol="org.apache.coyote.http11.Http11AprProtocol" />

Then I added
CATALINA_OPTS="$CATALINA_OPTS -Djava.library.path=$CATALINA_HOME/lib"
to $CATALINA_HOME/bin/setenv.sh
I also experimented with LD_LIBRARY_PATH

and... nothing as you see java.library.path is unchanged...

I also put these libraries in JAVA_HOME/jre/lib/i386 and... nothing

there's native library directory listing:

<code>
maciek@reaver ~/opt/tomcat/lib $ ls -la

drwxr-xr-x 2 maciek users 4096 2006-06-05 22:07 .

-rwxr-xr-x 1 maciek users 5788 2006-06-05 22:06 libtcnative-1.so.0.1.3
</code>

Library compiled without any fancy CFLAGS, using gcc defaults (i guess -O2),
not stripped

I'm using tomcat-5.5.17 (with servletapi-2.4 library), sun-jdk-1.5.0.06 on
gnu/gentoo box

Can you give me some ideas (in example what am I doing wrong)? - or maybe
some reasonable workaround

I need tomcat as native as possible

thx in advance

Any update on this? Im running into the same issure.

I have the the tcnative files under /usr/local/apr/lib

i have Djava.library.path set to /usr/local/apr/lib in Catalina_opts.... I am still getting an error that the native library is not found everytime i start my tomcat instances..

Any help would be appreciated.
