Thanks David,
Again, I want to start the prolog engine, so I need to load the
library of prolog when I start Tomcat 5.5.17. I think the command line
is: java -Djava.library.path=$PLLIBDIR $1
But I do not know where to put this command line in Tomcat in order to
load the prolog library when Tomcat starts. I am using Linux.
This is the error I get when using jpl methods to call prolog, just
because the prolog engine is not yet started.
Caused by: java.lang.UnsatisfiedLinkError: no jpl in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682)
at java.lang.Runtime.loadLibrary0(Runtime.java:822)
at java.lang.System.loadLibrary(System.java:992)

Many thanks,
Tu

Your log message sited below is not related to accessing jpl.jar. It's
just a message stating it couldn't use the new native APR connector and
is falling back to the traditional Coyote connector.
As far as an external jar file, best practice is include it in your
webapp in WEB-INF/lib. In $CATALINA_HOME/shared/lib if you are using it
accross multiple webapps.
