JSP :: Please Wait Page
Hi,
I have a jsp page which displays over 100 records from the database. While the fetching is done it shows me a blank screen. How can i avoid it? I want to show the user a page which displays a waiting message, while in the background the fecthing of the recodrs is processed. and as soon as the fetching is done..i want to redirect to it.
please help me out on this.
Thanks in advance.
One way to do this is...
Insert a page between the requesting page and the actual page that fetches the records.
In short if you have some thing like A -- > C (where A is the page that carries a link to C and C is the page that fetches the records), change it to A --> B --> C(where B is a page on which you display your nice 'Wait' message. In the source code for B, put an HTML meta tag like...
<head>
<meta http-equiv="Refresh" content="0; url=<put the URL pointing to page C here>">
</head>

Implementing a "please wait" page in a pageflow portlet
Hello-
I am using a page flow to trigger some actions on a remote system. The action
can take a few seconds to complete, and I would like to show an intermediate page
directly after invoking the action that would display a "please wait" message
while the action is finshing.
I was able to acomplish this outside the portal by the following:
-User clicks button to invoke action
-action just forwards to wait.jsp
-javascript in wait.jsp calls the actual remote action that takes a while
-when remote action has completed, action forwards to result page
This works fine outside the portal...I am simply auto-submitting a form on the
wait.jsp page with the proper action. The problem is that I can't get it to work
in the portal. I am unable to find a way to generate the proper url on the wait.jsp
page to submit to the action to that the page flow stays "inside" the portal.
If anyone has implemented this type of behavior in the portal, I would appreciate
any thoughts...
thanks,
HowieUnfortunately href generates the url internaly (with a quite complicated
algorithm), so I don't think you will find anything. A dirty manual
url generation (by examining some sample urls generated by netui:anchor)
probably might be much faster.
However, if you find something nicer I would be glad to hear about it.

Hi Don-
Thanks for the reply-
I tried using the <netui:anchor> tag, but the problem is that it generates the
entire <a href> tag...I need just the url value so that I can use it in the javascript
to auto-refresh the page to the proper action...
I may try poking around the API to see if there is something I use there...

Hi Howie,
I think you could try at least two methods:
1. Try to use netui anchor, which will generate a valid url for both
portal and standalone pages. One of the pageFlows probably should be
nested in the other one, so you can link it without problems.
If it doesn't work, or you can't use netui:anchor for some reason here
is another tip (It is not too nice, but I think it should work):
1. Try to get the last part of the URL: run the pageFlow without portal,
so you can get an url that points to it.
It will be something like this:
host/application/folder1/.../folderN/someAction.do or
host/application/folder1/.../folderN/somePageFlow.jpf
I guess you will need the .../folderN/someAction.do part as the relative
URL of the pageFlow/action.
2. Add a netui:base tag to your jsp page. It will create a prefix for
each urls on the page, so you can use the url you got in 1.
I'm not sure, but the url you got from 1 and 2 may overlap, in this case
you simply remove the overlaping part from 1.
Hope it will work,
don

Adobe PDF displays "please wait" preview in OPEN file under Windows XP
An Adobe form created in LifeCycle 8.2, enabled for Adobe Reader version 9, displays "Please Wait" page in the preview in place of the actual document form view. Is there a way to disable this error meassage?
Hi,
no you cannot change this behavior.
This messages is present in all XFA forms (dynamic PDF's) you create with Designer and will be displayed when the PDF viewer cannot handle the XFA data inside the PDF.
In general only Acrobat and Reader support XFA forms, most of the other PDF viewers don't. -
Question about Page Builder behavior - how to get a "please wait message" ?
Hi all together,
I got a question about Portal Framework / Page Buider handling iView Integration.
We are working with a lot of App Integrator iViews and often the pages includes with app integrator are loading longer than the rest of the portal. So there is the idea to put in a "please wait while loading message" for the enduser.
I analysed the html code, the page builder is generating and foud out 3 diffrent approaches how the page buider is rendering the IFRAME with the integrated application configured with an app integrator iView.
My question is how can I influence this behavior to put a "please wait while loading message"?
Different types of iView integration in the client I have seen:
a) direct loading of the content in the IFRAME (<iframe id="" ... scr="/mysource">)
b) Filling the iframe with 'about:blank' and loading the content later by filling a form with JS
( <iframe id="" .... scr="about:blank">and after the iframe <form id="" action="mysource" ...>
c) Filling the iframe with a html file from the portal layout and loading the content later by filling a form with JS (similar to b)
( <iframe id=""" ....scr="/irj/portalapps/com.sap.test.mylayout/html/blank.html>
I checked that variant b) is getting generated when loading a page with different components on the side (not only the app integrator iview) and variant c) is generated when just one app integrator iView is positioned (no portal page).
Goal: To get the "please wait picture" I want to know how to get variant c) in cases of different elements on one page
So I would be able to put this picture on the HTML-Page in the Portal layout (blank.html)
Hope, someone with a deep portal / page builder know-how can help me out!
Another way: Does anybody knows another way how to put a "please wait message" while app integrator application is not loaded yet?
Thanks in Advance and kind regards,
Jens
Edited by: Jens Kohne on Nov 24, 2010 9:08 AMHi Jens,
there are several reasons why you don't get the loading animation:
Web Dynpro ABAP: https://service.sap.com/sap/support/notes/1432358 -> missing configuration
Wrong height size for iView: https://service.sap.com/sap/support/notes/1358494 -> alter configuration of the iFrame height (loading animation gets displayed, but is hidden)
FPN, BSP, BEx: https://service.sap.com/sap/support/notes/1290995 -> AI isn't showing the animation because of performance considerations. I guess that is your case. Depending on your portal version this is a simple service configuration or involves some customization.

Display ("Please Wait") message WHILE the page loads
Hello All,
I have adf/jsf application. How to add message " Please Wait While Page Loads" WHILE+* the page is loading ?
I am thinking of Window.confirm(" Please Wait While The Page Loads") Is there a better (More Modern) way to do this?_
Many Thanks,John, when I type <af:statusIndicator and ctrl + space, JDev does not show statusIndicator as one of the choices. I tried adding code but it seems it does not recognize statusIndicator as one of the tags. I am using other jsf and adf tags on the same page :(

I am constantly downloading pdf's and excel files from our company software which uses a web browser to access it. When I download a file, firefox generates a full screen pop up window that states "please wait while we generate your document." My problem with it is the fact that pop up window does not close after the download. I have to manually close the window. Is there a way to set that pop up window to close automatically after the file has finished downloading and is open in foxit reader or excel or word or whatever?
Thanks,
TonyHi,
You could try is to '''Disable''' the Foxit, Adobe and Office '''Plugins''' in '''Tools '''('''Alt '''+ '''T''') > '''Add-ons''' and use the normal Firefox Open with (when you click on a link) to browse/open it in the required application.

I'd like to impose a 'please wait' screen between 2 JSP pages. I have a jsp page that prompts the end-user for reporting parameters, such as begin-date & end-date(and others). The user clicks a submit button which links to another jsp page that actually runs the report. The report page calls a bean that calls some Oracle packages, which in turn formats the results in an HTML table. Depending on the report parameters, it can take several minutes to generate the report (millions of rows possible). I want to have some kind of intermediate page with a please wait message, so the user doesn't get impatient and start clicking around, thinking that nothings happening. I have teenage daughters, I know the impatience routine all too well.
I thought about using a forward declarative, and an include, but based on the doc I've read, it doesn't look like they would work. Any ideas where I could go with this.
Should I have the destination page try to display the please wait screen, or should the caller display the screen and wait for the destination to catch up?
I'm still fairly new to JSP, but not new to programming (20+ years). Any help would be appreciated.Try using a wait page by putting this code at the top level of your page
if ( session.getValue( "waitPage" ) == null ) {
session.putValue( "waitPage", Boolean.TRUE );
// I have the WAIT_PAGE constant defined in an external file...it's just
// the html string that builds the "loading...please wait" message
out.println(WAIT_PAGE);
out.close();
}else {
session.removeValue( "waitPage" );
// End of logic for displaying the wait message
// build your page in here -
HI ppl,
Give me some ideas how to display a msg "Please wait while page loads " while jsp page is doing long database operations.
I know how to achieve this in html pages using javascript when page loads big image but with long database operations javscript trick doesnt works.
Any thoughts???
Thanks in advance.There is one little sneaky trick that might work, but I'm not sure if this will work all the time. Here's what you do:
1. page where you fill in a form to store in the database or something. Hit submit
2. submit to a simple JSP page which has the text you want to show the user, plus all the submitted data in hidden inputs. in the body tag, add an onLoad='document.formname.submit();' to submit the hidden input fields to the page that does the database action.
The old page SHOULD stay visible until the database operations are completed, as long as you don't generate ANY output before the database transactions are complete... but again don't shoot me if it doesn't (or better yet, shoot the browser for clearing the display buffer to soon) :-) -

Displaying a wait page without javascript/ meta refresh
I am using JSPs with struts 1. I wanna show a wait page after submitting the form until it process.
But in my case i wanna do it without javascripts or meta refreshes. any idea?ruwanin84 wrote:
As far as I know, meta -refresh is not that much recommended.Please elaborate and prove. This makes really no sense to me.
any way that's my last option. do you have any idea of checking the token?That's just a toggle in the request/session on which the server side code can intercept. This still require a request being invoked by the client. -

Dear Sir or Madam,
I have been experimenting with the evaluation version of WS2012e trying to get the installation and subsequent build into an optimal set up, and once I have everything I want it to do mapped out, I'll set it up with the full version with using the key that
I bought.
However, I've noticed that the server seems to experience a delay during cold boot - it sits with a Please Wait screen for about 60-90 seconds before it presents the screen with an option to Log on. I have also discovered from running Health
Report, that there are some entries in the event logs which appear to coincide with start up times, and which seem to be interconnected to each other in the issues they are describing, and I have copied an example of one of those health reports below.
I assume that everything sorts itself out in due course, because the events say the process will be re-attempted and these errors don't repeat again after the system has booted up. I also have the server set to suspend when not in use with the Lights
Out add in, so it shouldn't need to cold boot often - but I wondered if there's a way to correct these errors so that they don't hold up the boot up process? I'm also concerned that these errors will cause me later problems with storage pools and
the like at a later date - the disk replication one seems particularly worrying. Alternatively, are these errors just a normal part of the start up process - the timing of when different processes start relative to each other - and can be safely ignored?
In trying to understand what the events describe, I thought that WE2012e acted as its own Domain Controller, and yet it seems from the event log entries that it is waiting for another server to respond to AD / DC requests (but there isn't another server
on my home network). The other thing I remember from when I first tried out WS2012e, is that it took control of DHCP or DNS from the router, and I found that frustrating when waking up my laptop and it wouldn't connect to the internet until the server
had fully booted up and re-asserted its network settings. Is this another symptom of the same problem? I remember seeing a posting at the SBS Diva's site about how to update the server so that it gave connected PCs a backup option for connecting
to the internet when the server wasn't available, and was going to try to find that again to see if that helped.
By way of background - there isn't another server in my home network. This is an attempt to do a clean install onto the same hardware that I ran the initial trial of WS2012e, now that the trial has expired, so I'm not trying to migrate from an existing
server. I moved all the data on the trial server off onto an external disk, with the intention of importing it back once I had the Storage Pools set up the way I wanted on the new build, and since I didn't want to keep anything else about the server
trial. Am I correct in thinking that I don't need to go down the Migration route during installation, and can go through a Clean install in this circumstance?
I'm running on an Asus P8-H77-i motherboard, with an i5-3470s CPU and 16MB RAM, and I have WS2012e installed on 256Mb SSD formatted under GPT with uEFI boot - the latter being the main reason for the reinstall, instead of just giving the Evaluation
version the new key on the original MBR set up. I've also enabled Intel Rapid Storage and Rapid Start - and successfully set aside the hibernate partition on the SSD - but discovered that this is about forcing a hibernate after suspend, allowing
the system to power down until its needed again, and then resuming from hibernate on the SSD rather than cold boot each time. That seems to work, but doesn't improve the cold boot times at all, which was what I was hoping for - ideally the way my
laptop will boot from cold in a few seconds into Windows 8.
Yours faithfully,
Avon

The security of this directory server can be significantly enhanced by configuring the server to reject SASL (Negotiate,
Kerberos, NTLM, or Digest) LDAP binds that do not request signing (integrity verification) and LDAP simple binds that
are performed on a cleartext (non-SSL/TLS-encrypted) connection. Even if no clients are using such binds,
configuring the server to reject them will improve the security of this server.
Some clients may currently be relying on unsigned SASL binds or LDAP simple binds over a non-SSL/TLS connection,
and will stop working if this configuration change is made. To assist in identifying these clients, if such binds occur this
directory server will log a summary event once every 24 hours indicating how many such binds
occurred. You are encouraged to configure those clients to not use such binds. Once no such events are observed
for an extended period, it is recommended that you configure the server to reject such binds.
For more details and information on how to make this configuration change to the server, please see http://go.microsoft.com/fwlink/?LinkID=87923.
You can enable additional logging to log an event each time a client makes such a bind, including
information on which client made the bind. To do so, please raise the setting for the "LDAP Interface Events" event logging category
to level 2 or higher.

Hi Justin,
I'm reading through the links you referred me to but it's taking a while. In the meantime I tried running BPA as you suggested. I'm sure when I ran it before, it didn't say much beyond 81 checks completed, and I couldn't find a way to get any
more detail.
Now it says
Problem:
The DNS client is not configured to point only to the internal IP address of the server.
Impact:
If the DNS client is not configured to point only to the internal IP address of the server, DNS name resolution can fail.

To resolve this problem:
1. From the client computer, open the Properties page for the network connection.

How to send a 'loading, please wait...' message to user
My web application needs to load about 1000 item names to screen. It takes about half a minute before the names are returned.
While waiting, the screen is blank and user wouldn't know what's going on. Is there a way to send a first page ('Loading,please wait...')to the browser, and then desplay the result page after the procedure completed.
I searched in this forum before posting but didn't get help. I'm pretty new in this area, please help me.
Thanks.By clicking a button. It's like a principal logins to school site, the first page he/she sees is student name page, the page is a big dropdown down list with all the student names in this school.
I tried some javescript but didn't work. I think the problem could be:
1. it takes time to get data from table and generate a html doc.
2. it takes time to display the page.
Reason1 is main problem and any javascript won't work at this step.
Any suggestions, please? -
3 cfselect with "loading please wait" information
Hi
I have 3 cfselect boxes bind to a component. 2nd select box
is depend on the 1st and 3rd is depend on the 2nd.
Its taking much time to load the select boxes and before
loading all the information user is submitting the page, giving the
errors. and not only that if the internet is slow, its taking much
time to load the data.
So for this i want to display the word "page loading please
wait..." how can i do this? can I do this in CF or i need to use
the seperate AJAX for displaying it.If the amount of data is reasonably small, you might be
better off getting it all when you first create the page and using
js to control the selects. -
Jsp:useBean vs page import in JSP
Hi,
What is the difference between jsp:useBean vs page import in JSP?
By using page import also I can call the method of the class, apart from jsp:useBean does have scope associated with it. I don't think there is any change between both the 2. Yes by using jsp:useBean we can set the property and get the property as well.
Is there any major differences between the 2 and when to use which ? Please clarify.

Thanks.Yes there is a difference.
If you use import, then you have to create/use the reference object to use the class methods. And you can't define the scopes like session, page .. etc. Apart from this you will be using scriptlets <% %>.
if you are using jsp:useBean , then you can skip the above activities. useBean takes care of it.
or you can say jsp has provided a utility to access the beans without creating its object or using scriptlets.
