About jsp:forward

Hello everybody, sorry for my bad english.
Finally, I let my old post to ask my question differently:
Is it possible, with ADF, to start the application like this:
in web.xml:
<welcome-file>index.jsp</<elcome-file>
in index.jsp:
<jsp:forward page="/home.jsf"/>
Because personally, the only method I found is:
in web.xml:
<welcome-file>index.jspx</welcome-file>
with the appropriated configuration in web.xml (particularly a filter implemented manually).
If the answer to my question is yes, please, is it possible to see you web.xml file?
Thanks in advance.

Thanks for your answer.
In fact, nothing is bad with:
<welcome-file>/home.jsf</welcome-file>
But know if it is possible to use <jsp:forward page="/home.jsf"> could maybe help me to understand some things about the use of filters.
Personally, as I said before, I can effectively use <welcome-file>/home.jsf</welcome-file> but this implies to implement a filter.
In others libraries (even with Trinidad), this filter is never needed.
So, I try to understand the difference between those two methods.
And any information about this interest me.
Thanks in advance.

Qns about jsp:include and jsp:forward

It is said that <jsp:include>'s flush is only fixed to "true". Which means the page cannot pass its full control to another page using <jsp:forward> tag.
Is there any ways to overcome this problem? Using both in the same jsp and allow it to passes full control.

Hmm.. I'm using the form action to call back the jsp itself to validate something, and the include to add in another jsp file together with the original jsp to produce some addon visual effects.
So saying if validate is true, forward to another jsp.
So the form action.. cannot be use I think.

How do i pass a url with query string using the jsp:forward tag

This snippet of code gives a 403 error
<jsp:forward page="testpage.jsp?test=1" />
How do i rectify it?

Well better way to go about for the job is to use
setAttribute("name","value");method in the first page
and then in next page use method
String s=getAttribute("name");to retreive the value.
Url rewritting or using Query String has some disadvantages ,which are handled by above mentioned approach.

Filter problem with jsp:forward

Greetings,
I was trying to implement compression filter in oc4j. Basically wrap a HttpResponseServletResponseWrapper using a GZipOutputStream for supported browsers. However whenever for eg: I have a.jsp which does jsp:forward page =b.jsp I can see in TCP monitor IllegalStateException response already committed. But I dont see any stack trace in server logs. The buffer size is 2048 and I am pretty sure it did not get filled up before the forward. I would appreciate if anybody has seen such behavior using wrapped response in OC4j(the same code works fine in tomcat and websphere). Also one thing I observed is that for every jsp:include the filter is being called (to handle this I create the wrapper if its not already there and maintain entry count into filter and decrement when I exit filter and finish gzip response when entry count become 0,which works fine). I believe that this is not a part of 2.3 spec.Even in 2.4 spec if the filter config in web.xml is not set to any value by default the filter is supposed to be in request scope. I really appreciate any pointers in resolving this

I am pasting the stack trace for broken pipe exception. Please let me know if anybody knows the resolution. Please let me know if there is any other way to enable compression of jsp in oc4j in 9 version. The same code works in Jboss/tomacat websphere ! Also from the stack trace we can see that filter is being called for each forward and its not as per 2.3 servlet specification. Even in 2.4 by default the filter is supposed to work at request level.
Also I have another question oc4j seems to be using hard coded value: if length is more than 100k or so it uses Transfer-Encoding chunked. Is there any clean way of disabling this behaviour for .js files? the reason is for some reason Internet explore does not cache the javascript files properly (sporadically ) when chunked response is used for javascript files.

Hi,
Yes, I was able to code this sucessfully and got it working. Here is the code I used...
<%
String fortune = (String) request.getAttribute("fortune_string");
%>
<HTML>
<HEAD><TITLE>Fortune Sample Application</TITLE></HEAD>
<BODY BGCOLOR=#FFFFFF>
<H2>The Oracular Servlet greets you!</H2>
<p>
Your fortune is...
<%= fortune%>

<p>
<hr size=0>
<p>
<FONT SIZE=2>Sample Applications
<jsp:forward page="/ias-samples/index.html">
</jsp:forward>
</BODY>
</HTML>
and I got it working. I believe the code is missing some tag, which I tried, but got error in KJS like...

How to use TARGET in jsp:forward ???

In a link I can use TARGET to display the page in another frame like this:
<a href="http://localhost:8080/cars/Menu.jsp TARGET=FrameRight>Counties</A>
Is it possible to do something similar when forwarding a page with the jsp:forward standard action??
<jsp:forward page=SomePage" /">Would help me out if it was possible.</a>

No. It is not possible, '<jsp:forward' is not meant for opening the page in a said location. It simply forwards the request to the target jsp. Then your taget JSP will take care of resonding to the request.
If you want to open the page (jsp) in another frame, just stick on to the anchor tag and append your query string to the target jsp.
<% String query = "?name=xxx&age=30&dept=22"; %>
<a href="Target.jsp<%=query%> target="frameright">Counties</a>

Problem in jsp:forward

hi,
i have a jsp page from where i have to call my servlet.but it is mapped in xml by other name.so what should i do?can i call that servlet using named mapped into the xml.
can i do this?
<jsp:forward page="/servlet/web.xml mapping"></jsp:forward>
it's urgent.
so please help me.
kamlesh solanki

hey man,
how u doin?
your problem is quite funny. here in servlet configuration in the xml file there is what we call servlet mapping<servlet-mapping>.
here is how we map a servlet to a kind of url:
<servlet-mapping>
<servlet-name>
havet
<servlet-name>
<url-pattern>
/havva.jspa
</url-pattern>
</servlet-mapping>
nbow when calling this servlet using this url pattern it now behaves as if its in the main application directory just like where jsps are so u will forward to it like a jsp.
thats the shizzy.
ok call it like this now
<jsp:forward page="havva.jspa" />
or
<jsp:forward page="havva.jspa"></jsp:forward>
since u may be used to this style of calling the tag.
stay cool and let me know if u had any problems.

Jsp:forward failed with 'Response already committed'

I got a "Response already commited" error when using logic:forward or jsp:forward inside a JSP page fragment that is part of a Struts Tiles layout.
Here is the code fragment included in the layout.jsp.
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<logic:notPresent name="user" scope="session">
<logic:forward name="login" />
</logic:notPresent>
Here is the error message:
[ServletException in:/WEB-INF/tiles/verifyLogin.jsp] Exception forwarding for name login: java.lang.IllegalStateException: Cannot forward. Response already committed. (Servlet 2.3, SRV 8.4)'

Jsp normally buffers output in a 8k buffer and write it to the output stream (i.e. "commits") it when:
1) it is explicitly flushed
2) the buffer overflow
3) an jsp include is invoked
My code is in a layout.jsp file which is referenced in a tiles-definition. The tiles definition is tiles:inserted in a top-level jsp file. I am not sure if tiles uses jsp:include or if there is a way to get jsp:foward to work in the layout.jsp.

Problem using jsp:forward in java script

hi,
when I use jsp forward tag inside java script i'm getting a problem that
when the jsp is invoked it is getting forwarded to the page specified in the forward tag, without checking the if conditions. Following code may give you a better idea.
<html>
<script>
function test()
if(document.f.htemp.value=="true")
alert("jus");
else
var s=document.f.htemp.value;
alert(s);
<jsp:forward page="success.jsp" />
</script>
<body>
<form name="f" method=post>
<input type=text name=htemp value="true">
<input type=button onclick="test()">
</form>
</body>
</html>
please help me,thanks inadvance

chandu

What pgeuens means is that you can't mix javascript and jsp/java code in this way.
ALL of the jsp/java code gets executed at the server end.
This produces an HTML page (with embedded javascript) which gets sent to the client.
The client then runs javascript code in response to events (onLoad, onClick, onChange etc etc)
So in this case, the jsp:forward will always be executed, because as far as the server is concerned, the javascript is just template text.
If you WANT to do a conditional forwarding on the server side you do it in java ie (horribly using scriptlet)
<%
if (testCondition){
%>
<jsp:forward>
%<
%>Or if you want to test what the client has entered client side, all you can do is submit the form, or navigate to a URL
<script>
function test()
if(document.f.htemp.value=="true")
alert("jus");
else
var s=document.f.htemp.value;
alert(s);
document.f1.action="success.jsp";
document.f.submit();
</script>You cannot run JSP code based on your javascript code.
Java. Javascript. Not the same thing.
Hope this helps,

Jsp:forward URL problem

Hi,
I have 2 pages X.jsp and Y.jsp
The content of X.jsp is a simple
// send an email here
<jsp:forward page="Y.jsp">
</jsp:forward>
The content of Y.jsp is only "Mail is sent" message.
The problem is that everytime page X is loaded,
the browser displays Y.jsp content, but the URL in the Address box of the browser still displays X.jsp
This leads me to reload problem, even though the page displays the "Mail is sent" message, the URL still shows X.jsp, and everytime the browser is reloaded, another mail is sent.
How to make the URL change to Y.jsp ?
TIA.

One simple solution is not to use forward. You can use HTTP redirection rather than forward.

Jsp:forward param not getting included in my query string

Hi,
On a particular JSP page, mine.jsp, I am forwarding to a servlet ...
<jsp:useBean id="HotelResortDBBean" class="com.lvcva.database.HotelResortDBBean" scope="request" />
<jsp:forward page="/meetings/meeting-venues/results">
<jsp:param name="sqftRange" value="${empty param.meetingsqft ? -1 : param.meetingsqft}" />
</jsp:forward>This forwards to a servlet, when I query "request.getQueryString", it comes up null. However, when I enter the URL, "mine.jsp?sqftRange=-1", the query string returns "sqftRange=-1" as expected. Can someone tell me what I'm doing wrong in the above that is causing the jsp:param to not be added to the query string?
- Dave

a forward does not create a new request, and thus the query string is not altered. If you want the query string to change, use a redirect in stead.
note: even though the query string does not change, the new parameter IS added to the HttpServletRequest object, so you can still fetch the new parameter from it even with the forward.

JSP forward issue

I have a web application deployed on weblogic 8 server. I have a jsp (AddNewUser.jsp) which forwards to a servlet (CreateUserServlet.class) with the following code :
<jsp:forward page="/admin/CreateUser?userID=new"/>In the CreateUserServlet class, I have overriden init(config) as follows:
public void init(ServletConfig config)throws ServletException {
         super.init(config);
        context = config.getServletContext();
}In the doPost method, I have some debug statements as follows:
public void doPost(HttpServletRequest request, HttpServletResponse response) {
System.err.println("--------CreateUserServlet start------- ");
//initialization code here
context.getRequestDispatcher("/WEB-INF/jsps/admin/createUser.jsp").forward(request, response);
}The flow of actions is :
1. User clicks on a link to AddNew.jsp which forwards to the CreateUserServlet
2. The servlet performs some initialization (not shown) and forwards to createUser.jsp page
3. The createUser.jsp page contains a form which the user fills and clicks "save".
4. The form calls another servlet which saves the new user to the database.
The problem now which I have is that the web application works perfectly on 4-5 test machines except for the client ( what luck huh?). For him this is what happens
1. He clicks on a link to AddNew.jsp, he gets forwarded to the createUser.jsp page (as expected..no problem here!)
2. He enters some data and clicks "save" and the new user gets saved to the database.(as expected..no problem here!)
3. Now, when he tries repeating by clicking on the link to AddNew.jsp page, the debug statement "--------CreateUserServlet start------- " does not get printed to the console!!(HERE IS THE PROBLEM!) but he still gets forwarded to the createUser.jsp page! This is creating a problem because my initialization code is being skipped.
So, the client is able to enter a new user the first time he visits the section but is not able to add thereafter.
Any clues please?

I wonder if what is happening is when he clicks the link to AddNew.jsp teh browser is pulling the page out of cache. That would explain why he gets the CreateUser form without hitting the CreateUserServlet.
It is easy enough to check by enabling the access logs for your server. Then when he clicks on the link check the log to see if the request was recieved on the server and teh responce code is 304
If it is a caching problem there are pleanty of examples of the HTML meta data tags to prevent cahcing on the forum if you search for them.

Missing Parameters when JSP Forwarding

I am having difficulty with passing parameters when a forward occurs from
one JSP to a second JSP. When I try to get those parameters on the second
JSP I am getting nulls since it never actually receives them as parameters.
Here is what the code looks like ...
first JSP
======
<jsp:forward page="second.jsp" >
<jsp:param name="arg1" value="hi" />
<jsp:forward>
second JSP
========
String arg1 = request.getParameter( "arg1" )
This situation is occuring for me on iPlanet Web Server 4.1. (Fyi, when I
use the same JSPs on Tomcat through JBuilder, the parameter is passed to the
second JSP.) I am wondering if if I am missing something on how iPlanet
wants me to do pass arguments when forwarding or whether I just need to find
an alternative way to accomplish my goal. Thanks in advance.

In your second JSp try using.
String arg1 = (String) request.getAttribute('arg1");
I'm not sure if this is correct but from my understanding of Servlets you can not set a parameter programatically without overriding the ServletRequest. However, you can set an attribute. If this does not work then the following absolutely will:
JSP 1
<% request.setAttribute("args1","hi");
<jsp:forward page="second.jsp"/>
JSP 2
<% String param = (String) request.getAttribute("arg1"); %>
Hope this helps

Jsp forward problem, I think.....

I have a default.htm page that takes in a feild, EMP_NUM. Once the user
          hits the Submit button, I run a select statement(select.jsp) to see if that
          number exists. If it does then I forward the contents to correct.jsp, if the
          number doesn't exist then I forward to failed.jsp.
          Today is Tuesday, and last Friday I was working on this and everything
          worked fine, in fact perfect. I came in this morning to do some more
          testing, specifically catching errors in my try and catch, example - to make
          sure they enter in a number, and after I type in a number and hit the submit
          button, it trys to go to the next page, but displays nothing, the page is
          blank. Where has before, when everything was working fine on Friday, my
          correct.jsp page or my failed.jsp page would be displayed.
          From Friday to Tuesday I had not made any changes to my files. The only
          thing different, that I can think of, would be that on Friday I would have
          stoppped weblogic and this morning I started weblogic again. This is why I
          think this is a weblogic issue or syntax on my part. I have tried to restart
          my computer, restart weblogic, and I even deleted the .java files that
          weblogic creates and places in the weblogic/myserver/classfiles/jsp_servlets
          folder.
          Below is my source code.

          Sounds like you have some debugging to do. If you didn't reinstall WLS and it worked fine before,
          then I doubt it is a WLS problem.
          Is your page really blank? Try show source in your browser? I think you have some mismatched
          <table> </table>. Try it in both IE and Netscape - one of them forgives you for mismatched table
          tags.
          Add some System.out.println() in your code to see what is being executed.
