JSP page and the pageContext.forward() method
I am running JSP pages on a coldfusion site so that a CF page (i.e. login.cfm) hosts my login.jsp page. I want to reload the JSP page without having to reload the cfm page each time. pageContext.forward() does do this, however, it only forwards on to a new page. I want to be able to reload a page with the new URL parameters (e.g. when there is an error, login.jsp will reload and give the user an error). What is a method to reload the page with the proper URL variables?
The following code does not work:
pageContext.forward("login.jsp?operation=user_edit&jsessionid=" + f_URLEncode(session.getId()));
Because it runs from the login.jsp page (the forward command only goes to a new page)
Just to clarify...
I log into your site. The first page shown is the CF page. The CF page automatically redirects me to the JSP page. Then what, exactly?
Does the login page automatically determine my URL, attempt to validate it, and if it doesn't work, it reloads the page?
The reason I ask is because there is a difference between the resulting HTML page and the JSP class file that generates that HTML page. Generally speaking, most web servers, particularly Tomcat, do not recompile the JSP class file, they just simply pass the parameters to the existing class file, and a new HTML page is generated.
So technically speaking, every time you visit the login.jsp page, you will get a brand new HTML page. The contents of that page are the same because you presumably pass the same parameters to the class which hasn't changed. But in other words, no, you can't forward to an "old" page that was previously generated by the class - each time the web server calls that class, it creates a "new" page.
Or are you saying that every time you attempt to forward to the login.jsp page, the system erronously calls the CF page instead?

The content type for office excel 2007 in jsp page and the mime-type in we
Hi,
In my system MS Office 2007 is installed. I am trying to generating excel sheets from JSP page by setting the content type "application/vnd.ms-excel" in jsp page and as well as in web.xml file. I am getting the below message
The file you are trying to open, 'xxxxxxxx.xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
Then finally the excel file is opening and displaying properly. If in my system MS Office 2003 is installed , then the above message is not coming.
I have changed the content type according to Excel 2007 <%@ page contentType= "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" %> and in web.xml file the mime type to
<mime-mapping>
<extension>xlsx</extension>
<mime-type>application/vnd.openxmlformats-officedocument.spreadsheetml.sheet</mime-type>
</mime-mapping>
even the content type is changed according to office excel 2007 , i am getting the same above message.
My client is asking not to display the above message. So how to prevent that message ?
It's very great if any body reply me as soon as possible.Hi Akash,
I am not using the POI. I am generating the excel sheet using the below code.

How can I stop the execution on a JSP page and start it again
Hi
I am making a program that simulates how to manage transactions when accessing a database by using locks. I have run into a problem and I hope someone has the time to help me.
When a user does an update the transaction commits and releases its locks when the program executes
<%stmt.executeUpdate("commit!"); %>
I need to put a break in to stop the program executing this statement, to illustrate the lock is set correctly.
I have tried to put in an alert box but this does not prevent the rest of the java code being executed.
I have tried to use prompt boxes, JavaScript functions, but these functions cannot have any java code in them.
I have tried using the java.swing JOptionPane boxes but this didn?t work either
I have tried to get input from the user but I don?t know how to retrieve this data on the same page. (As far as I know you have to use submit and even refresh the page or retrieve it on the next page).
Does anyone know how I can stop the execution on a JSP page and start it again (on same page)
MetteI already have another client (Tomcat jsp application) running and it throws a SQLException correctly when I don�t put in a commit=true statement and don't close the database connection.
But the problem is how to get the code above to stop to illustrate I have set this lock.
I have tried to use the JOptionPane but because my program is running in a web browser I cannot use the JOptionPane dialog box.
I have tired using an alert box but it executes the commit statement before the alert box is dispayed. So this does not work
While (i < 2)
if( i==1)
%>alert(�The transactions commits when you press Ok�); <% //what it to stop execution here
else
stmt.executeUpdate(�commit�);
I am not using threads so I cannot use the sleep function.
I am using mysql and have already configured it to detect deadlocks and how long to wait for locks.
Thanks for your help

class paths are short. Here is my jvm.config (pretty standard):

is used
# if not then it must be the path to the JRE itself
java.home=I:/JRun4/jre

# 2) ../jre
# 3) registry (windows only)

I can not forward calls. I go to call forwarding, turn it on, copy and paste my phone number into the correct field (including the international dialling code).
I then tap the Call Forwarding button, which takes me back one stage and the Call Forwarding button goes to off after a couple of seconds. Anyone who can help?Yes, a blocked call will go immediately to your voice mail.
If you would rather not have that behavior, ask your cellular carrier if you can block that person through the carrier. -
Single signon between JSP page and Net.Data page
I am trying to setup a single signon between a JSP page hosted on a tomcat server, and a Net.Data page hosted on an IBM HTTP server. Both of these servers are running on an AS400. The JSP page (www.jsppage.com/menu) contains a link to the Net.Data page (www.netData.com/page2). In order to access www.jsppage.com/menu the user needs to login. Once this happens I want them to be able to go back and forth between the two pages without having to log in when they switch servers. Page navigation is handled through myServlet.java so that when a user clicks on a link the request is forwarded on to myServlet.java where the servlet determines where to redirect the user to. The servlet uses
RequestDispatcher requestDispatcher = getServletContex().getRequestDispatcher(url);
requestDispatcher.forward(request, response);
to forward the user to the correct page. This works fine for the JSP pages but when I forward to www.netData.com/page2 I get an error telling me the address doesn't start with a /. I also need to send the user name and password for the net.data pages to avoid the second login window to popup.
I understand that the requestDsipatcher.forward() method directs the browser to a page that is relative to the current root directory. If I try to use response.sendRedirect(url) I get sent to the right page but the signon window pops up. I would appreciate any help.I am trying to setup a single signon between a JSP

The servers keep track of the user by storing a cookie on the clients computer. The cookie is only valid for the domain that created it.
So, to make this work you need to send the username and password as part of the sendRedirect. the forward() method won't work.
What you could do is create some code on the .net machine that accepts username, password and target URL as input. Once it receives those parameters it should perform the .net login procedure and redirect to the correct page.
In your servlet you should pass those parameters on to the .net machine and the user should get the correct page without ever seeing any login windows.
Make sure to use https if you decide to follow this scheme since http will transmit the username/password in cleartext.

Submit the jsp page containing the textarea
Hi,
I have a jsp page containing the textarea and a submit button. This page is submitted using POST. In the next page the content of the textarea is obtained and displayed. Can anyone let me know if there is any maximum limit on the characters in the textarea?
I am using JRUN3.1.
If the characters in the textarea is increasing 2000 characters, in the next page if i try to get the content of the textarea i am getting as null???
please help me out.Hi,
There is a limit as to how much data that can be passed using the GET method. Dont remember it at the top of my head now.
It would be better to use the POST method.

How to redirect a JSP page after the session is killed
Hello!
I am quite new to JSP. I have a question about how to redirect a jsp page after the session is killed. Could anyone help?
thanks a lot in advance!You can't, directly. There's no connection betweenthe server and browser.
even after invalidating the session. we can do it
directly using the statement
response.sendRedirect("....");
or we can use the meta refresh tag.if session is invalidated and if we try to do response.sendRedirect(".. ") it throws IllegalStateException -
How to Link another JSP Page in the same portal component
Hi Guys,
I am a new guy to SAP, currently, I want to add href link to another JSP in the same component, so I used <a href="<%=webpath%>/jsp/AboutPage.jsp">, but obviously, the link can not display target page due to privilege restriction, does anyone know how to resolve this problem? thanks very much!
Best Regards
JamesThanks srinivas,
Sorry for late response, too busy yesterday.
Currently, I want to create a URL link in the page which links another JSP page in the same portal component, but the problem is this JSP page is under PORTAL-INF folder, so due to privilege problem, I can not create the link like the following:
<a href="jsp/test.jsp">Link</a>
I konw if I move test.jsp out of folder PORTAL-INF, the above way should work, but then, I found the JSP page can not access componentRequest and get resource bundle object.
Am I clear, please let me know, thanks!
Regards.

Pass the data back from the jsp page to the java code
Hi,
I have written an iView that receives an event using EPCF and extracts data from the client data bag.
I need this iView to pass the data back from the jsp page to the java code.
I am trying to do this using a hidden input field, but I cannot get the code to work.
Here is the code on the jsp page.
<%@ taglib uri="tagLib" prefix="hbj" %>
<hbj:content id="myContext" >
<hbj:page title="PageTitle">
<hbj:form id="myFormId">
<hbj:inputField id="myInputField" type="string" maxlength="100" value="" jsObjectNeeded="true">
<% myInputField.setVisible(false);%>
</hbj:inputField>
</hbj:form>
</hbj:page>
</hbj:content>
<script language=JavaScript>
EPCM.subscribeEvent("urn:com.peter", "namedata", window, "eventReceiver");
function eventReceiver(eventObj) {
var url = eventObj.dataObject;
var funcName = htmlb_formid+"_getHtmlbElementId";
func = window[funcName];
var ipField = eval(func("myInputField"));
ipField.setValue(url);
var form = document.all(htmlb_formid);
form.submit();
</script>
Here is my java code
package com.sap.training.portal;
import com.sapportals.htmlb.InputField;
import com.sapportals.htmlb.page.DynPage;
import com.sapportals.htmlb.page.PageException;
import com.sapportals.portal.htmlb.page.JSPDynPage;

public DynPage getPage(){
return new ListSalesOrderDynPage();
public static class ListSalesOrderDynPage extends JSPDynPage{
private String merong;
public void doInitialization(){
public void doProcessAfterInput() throws PageException {
InputField reportfld = (InputField) getComponentByName("myInputField");
if (reportfld != null) merong = reportfld.getValueAsDataType().toString();
public void doProcessBeforeOutput() throws PageException {
if ( merong != null ) setJspName("merong.jsp");
else setJspName("ListSalesOrder.jsp");

After receive event, then call java script function "eventReceiver" and call "form.submit()".
But .. PAI Logic in Java code doesn't called ...
Where is my problme ?
Help me ...
Regards, Arnold.Hi Arnold,
you should not do a form.submit yourself. Instead you can put a component called ExternalSubmit to your page:
ExternalSubmit exSubmit = new ExternalSubmit("EX_SUBMIT"));
exSubmit.setServerEventName("MyEvent");
This results in a java script funtion on the page which is called "_htmlb_external_submit_". If you call this function the the form gets submitted and your event handler is called.

Ive just learned that i can use loadjava to load jsp pages into the database.
Ive just learned that i can use loadjava to load jsp pages into the database. How is that possible. How can someone go to my lets say, index.jsp page and actually see it if its inside the database? What authenticates it? Where would you set the parameters to tell http(apache) to look inside the db for the pages?
Any ideas?Thanks for the reply. If I put the file on the database, does it have to be in a particular location? I've put it on the database server, launched sql*plus (as APPS) and ran the following:
execute dbms_java.loadjava('-v', 'ZebraGetPrinterFromXML.class');
PL/SQL procedure successfully completed.Then when I try to run a process that uses this I get this:
ORA-29540: class ZebraGetPrinterFromXML does not exist -
Stored application and the ExtendedAppAttributes.isStartable() method
Hi,
According to MHP 1.1.3 sub-chapter 10.14.2 the application could be launched also when:
- not_launchable_from_broadcast is set to "1"
- is_launchable_with_older_version is set to "1"
- some older version of this application is stored (but not the current version)
So it seems that the ExtendedAppAttributes.isStartable() method shall return true in this case.
However the specification describing this method says nothing about the is_launchable_with_older_version flag. Instead of it says:
"+An Application is not startable if ... The application is signalled as not_launchable_from_broadcast and is not stored...+".
Does it mean that application is stored also when the is_launchable_with_older_version flag is set to "1" and any older version of this application is stored (but not the current version)? And the ExtendedAppAttributes.isStored() method shall return true in this case?
Or the ExtendedAppAttributes.isStartable() method has nothing common with the possibility of application launching? That is, even if it returns false the application may be launched/started by the terminal/another xlet.
