I never got that when I used Tomcat with Tapestry.  How are you
starting Tomcat up?  I always used the Tomcat plugin for Eclipse and
it worked pretty well.  Another option for development is to use
Jetty/Jetty Launcher/Eclipse.  Jetty starts up much faster.  As for
hot code replacement, it works pretty well as long as I edit inside a
method.  It fails if I add class instance variables or modify the
method's signature.

/dev/mrg

Hello,
I use Cayenne with Tapestry and tomcat.

I fetch data from the DB using Cayenne The application runs well until I make 
change on the Java file like Home.java I have to restart TOMCAT new. Restarting 
the Application doesnot solve the problem.
Changing the Home.page or Home.html does not create the error.
The error i get is:
------------------------------------------------------------------------
      java.lang.ClassCastException
      de.model.MenuObject cannot be cast to de.model.MenuObject

------------------------------------------------------------------------

Anybody knows why or how can i solve this?

I face this problem only with Cayenne, cos using a sample List does not creates 
this effect.

Thx in advance.
