RE: Struts JBoss / Tomcat and From
Title: Struts JBoss / Tomcat and From Gregory Thanks for the input. It has been bothering me using ActionForm in the EJB layer, as you say it mixes view and model. The nested properties idea is great, thanks.

I thnik, this is not a clean design, since you make your EJB code dependent on Struts. Struts beloongs to the web layer, EJB to the businness layer. Your EJB do not need things like HttpRequest, so'd try to make them independet from the servlet.* package. I'd suggest a simple redesign. Use simple beans as value object and nest them in your action forms. Struts supports nested properties, so will not need to create delegating propertry setters and getters in your action form. (unless you want to do some conversions - ActionForms' properties should be string based, value objects should use the "real" type of the property) -- gR P.S.: Of course it would be nice, if struts.jar could be installed in server scope instead of application scope. I suppose, it would need some changes in the class loading in ActionServlet. - Original Message - From: Nortje, Andrew To: '[EMAIL PROTECTED]' Sent: Thursday, September 20, 2001 10:50 PM Subject: Struts JBoss / Tomcat and From I have deployed my app using JBoss/Tomcat. I recently started using the ActionForm as value objects in my EJB's. JBoss now needs struts.jar in the class path, so it can find ActionForm, so I put sturts.jar in JBOSS_HOME/lib/ext. This works fine put it kills struts. Struts now throws a ClassNotFoundException for my ActionForm's. If I remove the stuts.jar from the JBoss class path JBoss dies and struts works again.
