Moving from Struts 1.0b1 to Struts 1.0b3
Currently having a problem with migrating code from using Struts 1.0b1 to Struts 1.0b3 Everything seems to work fine apart from the fact that the validate methods on our form beans (ie subclasses of org.apache.struts.action.ActionForm) no longer get called successfully. I have had a look through the release notes and cannot find any reasons why these methods would no longer work. Any ideas people? The following error is what gets thrown in the tomcat log. java.lang.ClassCastException at org.apache.tomcat.facade.RequestDispatcherImpl.forward(RequestDispatcherImpl .java, Compiled Code) at org.apache.struts.action.ActionServlet.processValidate(ActionServlet.java, Compiled Code) at org.apache.struts.action.ActionServlet.process(ActionServlet.java, Compiled Code) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:509) at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.tomcat.core.ServletWrapper.doService(ServletWrapper.java, Compiled Code) at org.apache.tomcat.core.Handler.service(Handler.java, Compiled Code) at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java, Compiled Code) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java, Compiled Code) at org.apache.tomcat.core.ContextManager.service(ContextManager.java, Compiled Code) at org.apache.tomcat.service.connector.Ajp12ConnectionHandler.processConnection (Ajp12ConnectionHandler.java, Com piled Code) at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java, Compiled Code) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java, Compiled Code) at java.lang.Thread.run(Thread.java:479) Thanks in advance.

Moving from Struts 1.0b1 to Struts 1.0b3
As no-one has provided any thoughts on this one I thought I would repost and give a bit more detail on how the error is being caused. Problem: The validate(mapping, request) method on the ActionForm class is not completing sucessfully in Struts 1.0b3 where it was in Struts 1.0b1. Detail: This is a form that has a couple of struts file upload controls on it (as well as text fields etc) so I suppose that might be related somehow. The exception being thrown in the log is :- java.lang.ClassCastException: org.apache.struts.upload.MultipartRequestWrapper at org.apache.tomcat.facade.RequestDispatcherImpl.forward(RequestDispatcherImpl .java:144) at org.apache.struts.action.ActionServlet.processValidate(ActionServlet.java:21 37) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1564) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:509) at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.tomcat.core.ServletWrapper.doService(ServletWrapper.java:404) at org.apache.tomcat.core.Handler.service(Handler.java, Compiled Code) at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java, Compiled Code) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:79 7) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:743) at org.apache.tomcat.service.connector.Ajp12ConnectionHandler.processConnection (Ajp12ConnectionHandler.java:166) at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java, Compiled Code) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java, Compiled Code) at java.lang.Thread.run(Thread.java:479) Does anyone have any ideas? This one has got me totally stumped and without a solution we will have to remain on Struts 1.0b1.

Re: Moving from Struts 1.0b1 to Struts 1.0b3
Graeme Miller, As a solution you can have your controller do the validation instead of validating in the form bean. Let me know if you need any further help.

RE: Moving from Struts 1.0b1 to Struts 1.0b3
Unfortunately in my case the controller is not reused but the form bean is, meaning if I was to do this validation in the controller I would have to do it for every Action that uses this bean. Thanks for the suggestion but it looks like I will have to stay on b1 until a more stable release of Struts comes out (maybe the 1.0 final release?) > -Original Message- > From: Biswas Amalendu [mailto:[EMAIL PROTECTED]] > Sent: Thursday, 7 June 2001 3:31 a.m. > To: [EMAIL PROTECTED] > Subject: Re: Moving from Struts 1.0b1 to Struts 1.0b3 > > > Graeme Miller, > > As a solution you can have your controller do the validation > instead of > validating in the form bean.

Re: Moving from Struts 1.0b1 to Struts 1.0b3
Could you subclass the Actions so that they can reuse the validation code? Be sure to register this at Bugzilla if you believe it is a bug.

RE: Moving from Struts 1.0b1 to Struts 1.0b3
Graeme Miller, I was trying to replicate the situation that you have and I think what you need to do is, go to your struts-config.xml and for your specific action tag turn the validate to "true" if the validate() method of the form bean should be called prior to calling this action, or set to "false" if you do not want validation performed. Let me know if you need any further help.
