Tapestry Development w/o restarts.

["Jan, Andersson" <Ja...@agriculture.gov.ie>]

Hi,
For every change in the .java files I need to restart the App Server for the change to take effect. 
Actually the whole web application breaks with this exception if I dont restart:
(java.lang.ClassCastException: sso.engine.SSOEngine
	at net.sf.tapestry.ApplicationServlet.createEngine(ApplicationServlet.java:608)
	at net.sf.tapestry.ApplicationServlet.getEngine(ApplicationServlet.java:393)
	at net.sf.tapestry.ApplicationServlet.doService(ApplicationServlet.java:205)
	at net.sf.tapestry.ApplicationServlet.doGet(ApplicationServlet.java:172)
	at javax.servlet.http.HttpServlet.service(HttpServlet.java:195)
	at javax.servlet.http.HttpServlet.service(HttpServlet.java:309)
	at javax.servlet.http.HttpServlet.service(HttpServlet.java:336)
	at com.evermind[Oracle9iAS (1.0.2.2.1) Containers for J2EE].server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java:508))

Using Oracle9iAS OC4J 1.0.2.2.1 Application server (Which is Orion). Would it be true to say that this is the way it works?
Or is this a OC4J (Orion) specific problem and has anyone seem it before?

Thanks, 
Jan
