forward to pageB?
Thank you.gimbal2,
Thanks for the response. I did try it and I got a
compile error. I just realized that the error was
regarding a different issue.

Which jar file is required for jsp dynpro page programming ?
Hi all:
I use NWDS wizard to create one small jsp dynpro page application. However the project has some errors, it said "
This compilation unit indirectly references the missing type com.sapportals.htmlb.page.DynPage (typically some required class file is referencing a type outside the classpath) Test1.java NewParProject1/src.core/com/xinao/test line 0
" However, I found the class DynPage is not found in current project.
I have already added com.sap.portal.htmlb_api.jar into my project.
Where can I locate and find that jar file (which include the DynPage class ) ?Hi,
Refer the following link content. It has answer to your question.

Help required In JsP :emergency...
i want to display a set of data in a jsp page . on one jsp page , i select one date
this date is present in a form, nd it is passed onto a servlet file from where, a database query is accessed
this query compares the date entered by user, and that date present in a database table
then, selects other relevant data, and is stored in a bean
this bean is now added to an ArrayList from this ArrayList, using a for loop, i display those data in the next
page.
But I can't do this ..please let me know..what is the exact procedure..........this is an emergency situation for
me...so i will be looking for a quick reply...
Thanks & regardsyou mean getting the data from the beans and iterate it to the jsp? http://www.engineeringserver.com/blog/2008/01/30/coding-nasty-works-arounds-every-programmer-should-to-that-atleast-once/

The request parameters don't go to the "page.jsp"...
If someone else runs into this, here is how I solved the problem -
If you create a PrintWriter object with the autoflush option, it
doesn't flush the underlying buffer till you call println on it. I
looked through the generated code for the servlet, and it was doing a
JSPWriter.print() to output information.
So, I changed the ResponseWrapper to keep a handle to the PrintWriter
object, and then flush it in the filter, and that works.
Why the same code behaves differently in JRun & Weblogic, I'm not sure

Help required with locking of pages!!
Hi,
We have two different instances of HTML DB , when we export the application from one instance to another and install it there , the page locks donot seem to get carried ...is it designed to be this way or are we missing out something here...
Regards
NaveenNaveen - The page lock info stays with the development environment and does not go with the application.

Help!!!why the flag " jsp:forward" don't work?
the code like this:
<%@page buffer="none" autoFlush="true" %> //attention: buffer="none"
<%
long i=0;
for(i=0;i<10;i++)
out.println("@@@@@@@@@@@@@@@@@");
%>
<jsp:forward page="test.jsp" />
but it not turn to the page "test.jsp".Why?but it not turn to the page "test.jsp".Why? because of your page buffer being none.
According to the API:
forward should be called before the response has been committed to the client (before response body output has been flushed). If the response already has been committed, this method throws an IllegalStateException. Uncommitted output in the response buffer is automatically cleared before the forward.
Having a buffer of "none" means that any output you do is sent immediately, and is committed. So you can't forward/redirect after you start output.
Solution: give the page a buffer. Remove that page directive, and it should work.

Hello Techies,
I m New to JSP . I need to forward pages according to the if condition. I worked out the code as

<%@ page import="java.sql.*" %>
<html>
<body>

String str2=request.getParameter("password");
try

con=DriverManager.getConnection("jdbc:odbc:Login","sa","");
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from Login");
while(rs.next())
String str3=rs.getString(1);
String str4=rs.getString(2);
if(str1==str3)
out.println("Connection Succeded");
%>
<jsp:forward page="try.jsp" />
<%
break;

<TABLE border=2>

Here i m have created DSN namely Login and i m also having respected datas in database. It work fine showing me the results but it is not forwarding to the First.jsp file. I m having that file in the same folder
Here i m using Tomcat web container 4.1. Plz give me a suggestion. All suggestions are welcomed.

I have 3 pages ...1) index.jsp 2) Forward.jsp 3) welcome.jsp
I have 2 fields in the index.jsp once upon filling & hit submit it has to to go Forward.jsp page...in the Forward.jsp..i have coded only one tag with
<jsp:forward page="welcome.jsp" />
I have one question...once the page comes to Forward page...will it display the contents of the Welcome .jsp in the same page itself...or it will go to Welcome.jsp page..
As i saw it will display the contents of Welcome.jsp page in itself...
Please let me know...
Regards
GnaneshI understand your question only because I have a set up totally identical to yours. The thread Matt suggested does explain the situation (i.e. the server passed control to another page but the client doesn't know that), but doesn't necessarily give a good solution a problem that you may have, and that I do have:
If the user sees the welcome page, and for some reason decides to "reload", the forward page is re-executed, even though it has done its job. This could be a problem for session management if you specifically don't want that job being done twice in a session. Now you could hack around that, but I'd really rather see a neat solution. Is there one? -

Anybody have any ideas?
Thanks.Well, the simplest way to do this would be:
public class MyClass extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) {
String buttonName = request.getParameter("myButtonRequestVariable");
if ("update".equals(buttonName)) {
request.getRequestDispatcher("UpdateToCompAccount.jhtml").
forward(request, response)
} else if ("delete".equals(buttonName)) {
request.getRequestDispatcher("DeleteCompAccount.jhtml").
forward(request, response)
} else {
request.getRequestDispatcher("ErrorPage.jhtml").
forward(request, response)
public void doPost(HttpServletRequest request,
} But that can get unwieldy if you've loads of buttons. Have you studied the concept of Model View Controller (MVC)? -

at java.lang.Thread.run(Compiled Code)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>
<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...
[15/Feb/2002 11:23:49:7] info: --------------------------------------
[15/Feb/2002 11:23:49:7] info: jsp.APPS.fortune.fortune: init
[15/Feb/2002 11:23:49:7] info: --------------------------------------
Null text data??
2002-02-15 11:24:16 - error-the file '\fortune.jsp' generated the following pars
e exception: org.apache.jasper.compiler.ParseException: C:\iplanet\ias6\ias\APPS
\fortune\fortune\fortune.jsp(17,0) Expected "param" tag with "name" and "value"
attributes after the "params" tag.
In your case, I suspect, either the parser is not able to convert the .jsp file appropriately, or some inappropriate tag. If this doesn't help please send me your code & I can help you on this regard.

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>

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 solankihey 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.
Maybe you are looking for
