I have a JSP struts application that uses Spring to integrate with the services/dao/database. Basically, struts uses spring to get the data from the DB, it builds the form and forward them to the JSP files. I have a header file that is injected in each JSP file using Tiles. I would like to show "Welcome John Doe" on each page inside th...
Hi, I have a bit of an issue for my JSP site. I have it divided into three sections: a main folder within which a "resources" and an "actions" folder are. I house the files which show the site in the main folder, and validaton and action files in the "actions" folder. Upon entering a site, a user must login. I validate whether a user ...
Having replaced a <jsp:forward page="URL"> with a response.sendRedirect("URL");, I find I know lose the session once the redirect occurs. Is there a way to preserve the session with a redirect, or to reconstitute the session cookie and send it along with the redirect? I know I could use JavaScript via window.location = "URL";, but that ...

I have a JSP that has a Spring form in it. The form's command object is added in the controller before the JSP is rendered. Spring binds the form in the JSP to this command object, and will correctly handle it when submitting a NEW instance. However, I would like to persist the command object via DWR (which also works correctly), an...
I have a JSP, which includes another JSP via <jsp:include>. I also have (what I think is) a standard error page setup. The problem is that when an exception occurs inside the included file, it doesn't "bubble up" to the including JSP. Instead, it inserts the error page mid-way through processing the included JSP. Strangely enough, it...
In a jsp, how do you post a form without changing the page? In essence, I'm trying to: 1) First, kick off a servlet on the backend with a post to process the HttpServletRequest. 2) Second, once the servlet completes, a response message will be posted in a DIV on the page using prototype's Ajax.Updater function. All without leaving...
I am playing with Google's AppEngine Java support. I have a fairly simple set of JSP pages, and was looking at the logs today, and saw that I was getting a BufferOverflowException from the following JSP file: <% response.sendRedirect("index.jsp"); %> I simplified the file to just this, and I still get the error. Any ideas? Here is th...
I have done some research, and majority of the examples I have found use forms (obviously for user input) to collect data which is then passed to another JSP page through the request object. My question is: "Is it possible to pass a parameter between JSP pages IF the parameter hasn't been set in HTML tags?" Thankyou, Lucas ...
Is there a way to get which JSP is currently rendered, with JSTL or Struts (or without)? like _ _ file _ _ in Python and PHP? ...
Hi, I have code which generates some HTML, but when I try to output this content in a jsp all '<' are replaced with '<' and all '>' with '>'. Here is the piece which renders the result: <c:out value="${data}"/> Can someone please explain what causes the character replacement, and how it can be avoided? PS: I've tried escapeXml...
Hi. I've managed to deploy a .war to the Jboss web container containing and read the pom.properties located under /META-INF/groupid-dir/artifactid-dir/ To access the file I've used the following code inside a JSP in the same war: ServletContext servletContext = getServletConfig().getServletContext(); InputStream in = servletContext....
Hi there, Firstly, I have done my research and already know that JavaScript = client JSPs = server side. I don't want to waste your time. My situation is that I want to execute JSP code from an event (not from a HTML form). I have a HTML link (<a href="...">XXX</a>), which is NOT within <form> tags; it just an ordinary HTML link. Thro...
I've noticed that the javascript client-side validation feature of the struts 2 framework uses a javascript file that comes inside the struts2 JAR file. The javascript file gets included somehow in the JSP page apparently by just using a tag from the framework. If I manage to do this it will be extremely helpful for the many javascript ...
I'm new to JSP and Tiles, as well as Java. We are currently replatforming our site using these, but I am confused as to when something should be put into a view preparer vs coming from the controller. For example, the current page I am working on will have a tile for pagination, including the content type (X of Y content-type). My origi...
