Values on the jsp page not loading after refresh
Hi All,
I have a problem in getting the values back onto the jsp page after a refresh. After the first refresh i get null values.
Let me know what i should use: is it 1. request 2. application or 3. session scope? I have to keep my application running for ever (as long as the server is running) refreshing every 3 minutes. So i used application scope but in vain.
Also i am using requestDispatcher and forwarding the req,res. I came to know that this method has some problems if we use request attributes. Do i need to use a send.Redirect instead?
Let me know the correct procedure.
Thanks in advance.

Thanks in advance.r u forwarding request to same page. ?
try using sendRedirect with URL rewriting:
for eg .
response.sendRedirect("/myPage.jsp?id="+idValue+"");
and access id on page submit.
as
request.getParameter("id");
This should work .

Passing values to the JSP page - Urgent
Hi all,
I have to pass the user id value to the JSP page. I have written the following code in the doInitialization() method
IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
IPortalComponentContext myContext = request.getComponentContext();
IPortalComponentProfile myProfile = myContext.getProfile();
IAuthentication ia = UMFactory.getAuthenticator();
IUser portalUser = ia.getLoggedInUser(request.getServletRequest(), request.getServletResponse(false) );
s = portalUser.getUniqueName();
IPortalComponentSession componentSession = ((IPortalComponentRequest)getRequest()).getComponentSession();
Object o = componentSession.getValue("myEvents");
myEvents = (LoadEvents)o;
//myEvents = (LoadEvents) myContext.getValue("myEvents");
myEvents.setUserId(s);
myContext.putValue("myBeanName", myEvents);
I have also defined myEvents as a bean in my JSP page with scope APPLICATION. But I get User Id as "NULL".
Thanks in advance.

Help needed urgently to get the values from the jsp page.
hi,
I am badly stuck into this problem.Please help me and find a solution.
I am using ms-access and jsp.
my database structure is as given below:
m_emp_no | from_date | to_date | approver| status |
1002 | 22/9/2008 | 23/9/2008|1003 |pending
1004 | 29/9/2008 | 30/9/2008|1003 |pending
2044 | 15/9/2008 | 16/9/2008|3076 |pending
now this is exactly a leave apply scenario where a page is displayed and the user has to fill in the details to apply leave.then the approver has to approve that leaves so even, he should get the details in his account.
for example here 1003 has to approve leaves for 1002 & 1004.i am able to fetch data from database for the particular approver here is the coding:
<html>
<body>
<h2 align="center"><u><b><span style="background-color: #FFFFFF"><font color="#C0C0C0" face="Comic Sans MS">Leave

</tr>
</table>
</td>
</tr>
</table>
</form>
</body>
</html>{code}
this will display both the rows but when i try to retrieve the values into update.jsp using the code given below it gives me only one value which is the first 1002.
{code}approved=(String)request.getParameter("approved");
id=(String)request.getParameter("id");{code}
but i need both the values to be inserted into the update.jsp only then the approver will be able to approve the leaves individually with respect to the m_emp_no.
please help me out.
thanks in advance.My comments below are all between (((((( and ))))))

I have tried installing the older version Firefox 3.6. After entering the URL on address bar it does not load after pressing enter or CTRL+ENTER
This issue can be caused by an extension (AVG Safe Search can cause this) that isn't working properly.
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

The page is working fine. That is we can move the values in the left field to right as single or group.After submitting I need to get the values in the left & right fields respectively.
I have used the method
request.getParameterValues("lstProviderLeft");
and pointed this to an array of strings,but it returns 'null' .
How can I solve the above problem....Post your comments on this issue
Thanking uprobably the request.getParmeterValues will not work in this case as the name of the 2 select boxes are different....
You can do this utility by using Javascript....concantinate the values of the 2 select boxes and put the concantinated strings (with a delimiter) in two hidden fields and capture the same fields in the target JSP/Servlet.
I have modified ur code...have a look...

How can I make the jsp pages not displayed by using the navigation class?
I'm right now implementing a function on my program GUI . It's like whenever I click "STOP THE SERVER" button on the main page, I need those jsp pages relates to the server running to be not displayed, even by directly type in the URL(that's just stay in the main page), How can I do that? I heard that a navigation class might do it, but I'm not sure how. It might be great if some experts could help me!! Thanx a million !!

ECP Page not loading after installing SP3 on Exchange 2010 CAS&HUB Server
I have installed SP3 on my Exchange CAS Server after that OWA was not working, hence I have reset owa, ecp,ews,oab, autodiscover & active sync virtual directory from EMC. After that OWA is started working.
But While accessing ECP , content is not loading properly. I have reset virtual directory of ecp 2 times but problem is still same.

Pages not loading until refresh
Hi all,
Recently I have noticed on my Ipad and PC that webpages like google for example do not load, they get stuck until I refresh then it will go through and load the page. Also youtube has problems when I am using the ipad with certain videos just refusing to load. Wat can I do to rectify this problem!
Thanks
I am using a Netgear R6300 routerCould be a DNS problem. Try using Google DNS instead - 8.8.8.8 and 8.8.4.4

Page not loading until refresh still in 4
I don't know if anyone else gets this and I would be interested to know why it happens.
Occasionaly I will pick a site that just sits there try to load. Reselecting it makes it load no problem.
What could cause this?
One other thing that bugs me the search forum bar on the right of you screen why does it have a small search bar within a bigger one, its been that way for a long time.
Many thanksHi,
What could cause this?
That's usually symptomatic of DNS lookup issues. Try using the DNS settings provided by [OpenDNS|www.opendns.com] to see if it makes any difference.

Dodgy coding on the forum page, nothing more than that I'm sure Apple will eventually get around to fixing it. -
Pages not loading after pressing the enter button

Web pages not loading after removing **** blocker
I installed a **** blocker on my iMac and was not able to open certain sites. I removed the **** blocker and still can't open sites (not ****). I ave unplugged and plugged. I have reloaded Safari and the OS X. I have downloaded software from anti-spam to malware and still I can't access certain sites.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software. -
How to load only the jsp page even after applying template
Hi,
I have a webpage template with header,footer, Dynamic Menu etc. Now I assigned this .jtpl template to all my existing fases jsp files.
The problem is when I submit a form in jsp, the entire page including template gets loaded again by which we can notice significant time for loading menus and other things.
Is there any way to avoid this entire template loading and make only the jsp page to load? Please help
May be this can be achieved by frames. But I dont have idea on how I can merge template with frames. If someone can provide that even would help me better.
Thanks in advance.Hi
I found the solution .
<html>
<head>
<script language="JavaScript">
function checkRefresh()
if( document.refreshForm.visited.value == "" )
alert('first ime');
// This is a fresh page load
document.refreshForm.visited.value = "1";
// You may want to add code here special for
// fresh page loads
else

Get Javascript Value in a JSP page
Let's say this is my javascript function in a html page
.<head>
<!-- Function getFields -->
function getFields(){
if (row >= 0){
for(var i=0; i<costForm.elements.length; i++){
if(costForm.elements.type == "text" || costForm.elements[i].type == "hidden"){
dynTableFields[i] = (costForm.elements[i].value)? costForm.elements[i].value : "";
if(costForm.elements[i].type == "select-one"){
dynTableFields[i] = costForm.elements[i].selectedIndex;
</head>
How do i get the costForm.elements.length value in another jsp page. Coz the html page has dynamic rows by the users. and i need the values in the jsp page to know how many rows the user created.
using normal request.getParameter("costForm.elements.length") doesn't workrequest.getParameter() will only get data that's been submitted thru a form or the query string of a URL. You'd have to record the length in a hidden field to read it on the back end, and then you can't just loop thru the fields like that in JSP on the server anyway, unless you have all fields named with a prefix and number, like: field1, field2, field3, etc.
