Re: Classpath problems with tomcat on Linux 9
Figured out my problem. I wasn't placing the class file in a subdirectory of the WEB-INF/classes/package. Solution: created UserData.java with package name userdata created directory WEB-INF/classes/userdata placed UserData.class in WEB-INF/classes/userdata Thank you all who responded, and anyone else that read this and spent more then the time to click the delete button on it. -Andy.

Re: Classpath problems with tomcat on Linux 9
Still no luck. I'm basically trying to do exactly the same thing that the jsp-examples/checkbox is doing and I can't get Tomcat to recognize my UserData.class file. I've tried placing my UserData.class file in every location possible, and no luck.

Hi Andy, I'm porting over to TC5 and I've not had any problems with it finding my classes, *BUT* I don't put any classes into the base directory itself, but below that.
