Hi Matt, Today I was trying to port one legacy application from JRun to Tomcat & facing same problem with URL. URL.setURLStreamHandlerFactory.java.lang.Error: factory already defined 1. I tried out setting -Djava.protocol.handler.pkgs=<my.package> pointing to where my CustomURLStreamHander is present in catalina.sh 2. Added the required jar common/lib & other mentioned places
As you have said both didn't help as "java.protocol.handler.pkgs" setting is not working. http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/org/apache/naming/resources/jndi/Handler.html I also did not find anything about this is Tomcat configuration files. Do let me know if you find some solution to the same. Thanks, Praveen M.
