Re[2]: Struts in Tomcat 4.0
Hello Craig,
Thank you, now all is ok. But one problem. If I set -security option
to start Catalina then I view exception 'ClassNotFound' at struts
datasource init moment. Remove -security option - works fine.
Jar with JDBC driver is in JAVA_HOME/jre/lib/ext directory. This
driver uses JNI to connect to the database. May be problem disappeared
here?

In theory, JAR files that are placed into $JAVA_HOME/jre/lib/ext are
supposted to receive all security manager permissions. But that hasn't
always appeared to happen in my case. But it's hard to debug without a
stack trace.
One thing to try would be placing the JDBC driver inside your /WEB-INF/lib
directory instead. Of course, if you do this you will also need to edit
the catalina.policy file to give this JAR file the permissions it needs to
load a JNI-accessed library.
