I'm happy to say that I have discovered the solution to this problem as well as my problem with NoClassDefFoundError for HttpServlet...
It wasn't related to Wicket in any way. The problem seemed intermittent and now I know why. It depended on what directory I was in when I started Tomcat. I wanted to save myself some typing, so I made symbolic links to $CATALINA_HOME/bin/startup.sh and $CATALINA_HOME/shutdown.sh and put them in ~/bin, which I've added to my path. I know there is some code in those shell scripts to detect if the command that called it is a symbolic link and take appropriate actions based on that, but I guess it doesn't work perfectly. I've changed my symlinks to actual scripts, with two lines each. Change to the Tomcat directory, then run startup.sh. Now everything works fine every time :) Thank you all for your time and consideration. -- Vince On 9/4/07, Ghodmode <[EMAIL PROTECTED]> wrote: > > I'm having a problem deploying a Wicket application, so I create a basic > HelloWicket app and I'm still getting the problem: > > java.lang.NoClassDefFoundError: > org/apache/wicket/protocol/http/WebApplication > > Apache Tomcat 6.0.14 > Java 1.6.0_02-b05 > Wicket 1.3.0-beta3 > > I think that this is a Tomcat problem.
