Re: Tomcat can't find Java Beans
This is really bad. I just reloaded the application and it started running properly, Tomcat can now find the bean... I hadn't created the tomcat6 user yet. I believe yesterday, in the midst of all those back and forth e-mails, I must have fixed something, possibly related to permissions. The way I installed Tomcat all resources are owned by the root and something might have been inaccessible. I'm sorry for taking your time like this and inadvertently creating such an amount of mail traffic.

If you want to keep Tomcat on port 8080, you don't need to do anything other than run it under its own userid (and fix the file ownership, of course). Using jsvc is appropriate when you want Tomcat to use port 80, which is normally accessible only to root. Another alternative is to leave Tomcat on 8080, and use iptables to route requests for port 80 to 8080. Running Tomcat as root is a major security risk, since a small bug in a webapp could open up the whole file system to abuse. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

You installed Tomcat as 'root', but are now running it as 'tomcat6'? Make sure the whole tomcat installation is owned by the tomcat6 user, if that's what you're using to start Tomcat. N.B.

Tomcat can't find Java Beans
Hello everyone, Tomcat 6.0.20 on Ubuntu 9.10. I'm trying to deploy simple web applications that either use beans or servlets. I'm now down to very simple examples like this one: http://www.roseindia.net/ejb/introduction/javabean.shtml This is basically a html file, a jsp file that deals with a post and a java bean. I'm compiling the java files and copying the resulting .class into WEB-INF/classes, using the directory structure to match the package names. Invariably, when the bean is called Tomcat returns an error saying the bean is invalid (see example below). It seems that Tomcat isn't finding the .class files; do I need to configure something for Tomcat to find the beans? I though that for Tomcat 5 and beyond that wasn't needed. Thanks for your help, Luís - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
