William, Isn't it best practice to place ones JSPs rooted under /WEB-INF. This ensures that your JSPs are never directly accessible from the outside while still allowing your ActionBean's to forward to them.
If you followed this then Tomcat nor any other Web Container would succeed in placing a slash and matching your JSP structure. Or am I missing something...? --Nikoloas Rose William wrote: > Hi there, > > I found the recent discussion on the mailing list about clean URLs > seemingly failing to find the right event handler when a form is POSTed, > and saw a variety of solutions to creating the URL oneself. > > After trying to debug the same issue myself, I think the reason for this > behaviour is tied up in Tomcat bug 32424 (see > https://issues.apache.org/bugzilla/show_bug.cgi?id=32424). > > > My web app is set up with DynamicMappingFilter applied to /*. > > I have a WEB directory structure like this: > > /jobs > /edit.jsp > /list.jsp > > I have an action bean annotated like this: > > @UrlBinding("/jobs/{$event}/{fullName}") > > There is a list event, new event and save event: > > //@DefaultHandler > @DontBind > @HandlesEvent("list") > public Resolution list() throws SchedulerException { > s_log.debug("in list()"); > > return new ForwardResolution("/jobs/list.jsp"); > } > > @HandlesEvent("new") > @DontValidate > public Resolution newJob() throws SchedulerException { > s_log.debug("in newJob()"); > > return new ForwardResolution("/jobs/edit.jsp"); > } > > @HandlesEvent("save") > public Resolution saveJob() throws SchedulerException { > > return new RedirectResolution(JobAction.class, > "edit").addParameter("fullName", this.jobDetail.getFullName()); > } > > > > In edit.jsp, I have a form like this: > > <stripes:form name="jobEdit" id="jobEditForm" > beanclass="myorg.action.JobAction"> > [form fields] > <stripes:submit name="save" value="Save" /> > </stripes:form> > > > What happens is that when the page is rendered, I get HTML like: > > <form id="jobEditForm" name="jobEdit" action="/contextPath/jobs" > method="post"> > > > The important thing to note here is that /contextPath/jobs resolves to a > folder -- the one that contains edit.jsp and possibly other resources. > Ostensibly, DynamicMappingFilter caters for such things because it waits > until the request 404's before handling it.
