I recommend SDN's JSP forum : http://forum.java.sun.com/forum.jspa?forumID=45
And for JSP Tag Libraries this mailing list : http://jakarta.apache.org/taglibs/#MailingLists 1) I tested your jsp: include, both files returned the same size when tested with Firefox's page size extension tool. I got 19KBs in both cases. But if you just look at the size of test.jsp *before* it translates and processes the request, it's size is 0.1 KB because of the code it contains. 2) This syntax <%@ include file="request.getParameter("f")" %> , is not correct. The correct syntax only allows a URL in the file attribute as shown here: http://java.sun.com/products/jsp/syntax/2.0/syntaxref209.html#1003408 , since the include is a directive and not a JSP action. Another option is to use JSP Tag Library (JSTL 1.1) : c:import tag. The details for this tag are here: http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/index.html But this first requires you to install JSTL 1.1, and knowledge of how JSTL and Expression Language works (If you want to use JSTL - since it is better than JSP scriplets and JSP expressions) -Rashmi ----- Original Message ---- From: Xuekun Hu <[EMAIL PROTECTED]> To: Tomcat Users List <users@tomcat.apache.org> Sent: Monday, January 15, 2007 1:23:21 AM Subject: Questions about JSP programming Hi, Sorry for the off-topic questions, since I didn't find a good forum to discuss JSP programming. :-). If you have any recommendations, I would be very appreciated. I have two questions. 1. I wrote a test.jsp to test dynamically return a static file from the request parameter. ////--- test.jsp <jsp:include page='<%= request.getParameter("f") %>' /> The problem is that the return size is always greater than the request file size by 1. For example, the static file is 512byte, however it return 513 byte. The result is repeatable. Does anyone know the reason? 2. I implemented the test.jsp by another include usage. ////---test.jsp <%@ include file="request.getParameter("f")" %> However tested with lots of simulaneous request of the same jsp, some request will get "500 internal server error"!. What's wrong? Thanks in advance.
