New Windows, Struts, IE 5 and sessions dying
Summary: Any known bugs and workarounds with Multiple Windows in IE5, Servlet Sessions and Struts 1.0b1? Detailed Version: We are using Struts 1.0b1 and Tomcat J2EE form-based login security on our website. The user requests a protected page and is automatically redirected by Tomcat to the login page from which they login and enter the site. The password and username gets stored in a session automatically by Tomcat for use in further protected pages. No problem there - it works perfectly. However when we open a new window using the javascript functions window.open(url), window.showModelessDialog(url) or window.showModalDialog(url), things go badly wrong. The moment the new window is opened the user has to log in again in the main window before they can do anything else. Had a look at the HttpServletRequest and the the j_username and j_password variables appear to be deleted from the session attributes the moment you open the new window, but the cookie with the session id still appears to be present. After considerable effort we have narrowed the problem down to Struts itself. If we open the new window with a url that is just a static file (html,gif etc) the session doesn't get lost. If we open the new window with a url that is a jsp file that doesn't involve struts once again everything continues working fine. But the moment we open the new window with a struts url (ie *.do) the session gets lost in the main window. Has anyone else had this problem? Any known bugs in Struts 1.0b1 that we should be aware of? Any known solutions/workarounds? Help! Thanks, Graeme.
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: invalid multipart request in beta 3
Peter that's a very similar error to what I am getting and I am doing the same thing (migrating from b1 to b3 with file uploading).

RE: invalid multipart request in beta 3
Are you using IE 5.5? Coz there are some documented issues with IE5 and below and file uploads in Struts. Unfortunately I AM using IE5.5 and this is not working for me in Struts 1.0b3 where it was in Struts 1.0b1 so something has definitely been broken in either b2 or b3. > -Original Message- > From: Peter Doyle [mailto:[EMAIL PROTECTED]] > Sent: Thursday, 7 June 2001 4:29 a.m. > To: [EMAIL PROTECTED] > Subject: RE: invalid multipart request in beta 3 > > > The form tag uses enctype "multipart/form-data".

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: Override the presentation of html:errors
You have some control over the format of the font and background etc by setting the errors.header and errors.footer properties in your ApplicationResources.properties file You can put html tags in these headers and footers eg. errors.header= errors.footer= where errorMessage is configured via a stylesheet Regards, Graeme. -Original Message- From: Jeff Trent [mailto:[EMAIL PROTECTED]] Sent: Wednesday, 2 May 2001 8:36 a.m. To: [EMAIL PROTECTED] Subject: Override the presentation of html:errors Short of writing my own taglib (which I'd like to avoid if I can), how does one iterate over the errors collection to present them in a different way. Any examples would be helpful... Thanks, Jeff
File uploads and Struts
Anyone here know where I can find a tutorial or explanation on using the tag for file uploads? The struts documentation is fairly thin on this area. Regards, Graeme.
