Invoke servlet with javascript
Hello.
I need to invoke a servlet with javascript when the user clicks a button.
Is there a way to invoke the servlet without submitting the page ?
Thanks in advance.
onchange="location.replace('ServletName');"

Hi all;
this is the process.
1. Servlet received / creates msg.
2. Servlet Enqueues Msg on JMS queue.
3. MDB dequeues.
-- processes against DB
-- composes respoonse.
4. mdb invokes servlet with response.
servlet need not maintain state.
State information can be passed in Msg (Query and Response)
I was just wanting to find out if this possible in oc4j.
apparently, there is a process in weblogic 6.1 to support this.
Any help is appreciated.
thanks.
jayantI would assume that you would need to do a "createSipApplicationSession" on your sip factory and then get the ID from there.
Then create a request from your session and send it.
Wouldn't you want each outgoing call to be associated with a different sip app session? -
How to configure IIS webserver with weblogic so that I can
invoke servlets without the .wlforward extension
As per the documentation iisforward.dll is registered as a filter and .wlforward
has also been
included as a special file type. However this requires me to key-in ".wlforward"
after my servlet name.
What I want is something like this
http://iis/MyServlet
Please help me find a solution to this
Thanks,
RishiI am able to invoke the servlet without the wlforward extension now.
However, now I am required to add /weblogic before the servlet
name otherwise it does not execute the pathtrim property.
I have tried with the pathprepend thing also.
Can we get rid of the /weblogic part also. I just want to execute
my servlet as http://iis/myServlet.
Your help in this regard is greatly appreciated...
Thanks..

Thanks for the reply Kumar.
I did follow the instructions as given in the Weblogic documentation
The documentation said to add iisforward.dll as a filter service
and register .wlforward as a special
file type to be handled by iisproxy.dll. For this,
while configuring the IIS server in the Home Directory tab
I added an extension ".wlforward" and the executable as
iisproxy.dll. Is this the way it should have been done...
I also modified the iisproxy.ini file as per the documentation.
I have added the WLForwardPath property and set it to /weblogic.
My server works fine when I give the url as
http://iis/myServlet.wlforward
but it does not work for
http://iis/myServlet and this is the way i'd want it to work.
Please tell me if I am missing something on the configuration part
and if there is something special that needs to be done. I shall
be grateful to you.

ERROR RENDERING PDF IN SERVLET WITH FORM method="post"
Hello,
we are trying to render a dinamic PDF document in a servlet building with XSL:FO apache or itext.
The problem ocurs when we sending a Form data with method post, the output of the servlet is a blank page instead of the pdf document. Also if we send the form data with method "get" we can view the pdf document corretly.
But we need to send amount information, and can?t use method get.
ThankYou can always use GET to send information by generating a dynamic URL in the query string (after the '?'). Granted, you don't want to send file data that way, but it will work for small numbers of arguments where privacy is not a concern.
As to why you see the PDF in one instance and not another, I'm not sure. There is no difference from an HTTP standpoint. You sent a request, you are getting a response. The browser should treat the response the same, regardless of GET vs POST.
Are you setting the content-type to application/pdf? Are you doing something fishy with Javascript? Do you have conditional logic in your code that fires on a POST but not on a GET that actually has a bug in it (since GET works but it was designed for POST)?

Servlet with HTML using JDBC lookup
Dear Friends
How are you?
I am designing a servlet with two drop down lists one on top and the other below.
I implemented drop down lists using dynamic embedded HTML and SELECT tags.
I want the user to make a selection in the first drop down list, and the second
drop down list should display a list based on the selection made in the first
drop down list.
Please comment in detail on the most efficient way of achieving this.
Thanking you
Very truly yours
Sriram (Ram) Peddibhotla, PhD
For this I'd probably load all the values for both drop down list and use
javascript.

Calling servlet with out entry in web.xml
Hi
I want to know whether can a servlet be invoked with out having an entry in web.xml.Because to my knowledge when ever an entry is made in teh web.xml the <url-pattern> and the class file will be stored as key value combination it is only then when ever a request is made the server gets the class taht is to be invoked from the <url-pattern> that is passed from the client side.
Is ther any way by whihc we can call the servlet directly with out an entry in web.xml
Thanks in advance
Ajithkumar.SInteresting that it is possible on Tomcat anyway.
What's the real benefit of not having a Servlet
definied in web.xml?
The only benefit I see is that
you don't need to understand/read/change XML when
adding or removing a servlet. That isn't worth that
imho. What are the other benefits?The only thing I can think of is , to be able to quickly access a Servlet that you've just written, because it takes additional steps to define it in the web.xml.
I think it would be a security concern (of some sort) , if the Servlet's class is known, that's why it is better to access a Servlet with a mapping from web.xml -
Passing parameter from Servlet to javascript in JSP. Very Urgent - 5 jukes!
Well my servlet will retrieve questions from database.
Then the player will answer the question in the JSP and submit the answer to the servlet to process.
Each time an answer is submitted, or a "Next Question" button is clicked, the countdown time will restart.
And will reload the page with a new question.
So how can i do that?

in the servlet init() method trace out some debug to ensure that new

How do I invoke Servlets...continued
My posting appears to have been truncated, so here is the remainder:
(continued)
'Pilot' is a servlet defined and mapped in my web.xml file. But when I attempt
to invoke the servlet in the app with any of the following:

http://localhost:7001/pilots/pilot
http://localhost:7001/pilots/servlet/Pilot
http://localhost:7001/pilots/servlet/pilot

However, the following JSP, which is part of the same web application component

Hi,
I am interested in knowing why we should avoid invoker servlets?
what are short comings of invoker servlet?
( Yes for invoker servlets completer path up to servlet is to be given)
ThanksThe Invoker servlet is a built int servlet mapped such that allows you to invoke any servlet by using the URL: /servletPackage/servletClassName. While this is good to get started and to know, you should never use it in a production environment.
If you give password protected access to a folder, say Employees and map a servlet to /Employees/MyServlet, the servlet is also protected. Only people with the authorized username/password combinations can run the servlet. But if you allow the default mapping with the Invoker servlet, then the same servlet will also be accessible to everyone as /servlet/MyServlet in which case your authorization fails and everyone has access to your servlet's functionality, potentially modifying data etc.
This is only the authorization aspect. Other than this, the Invoker servlet makes it hard for you to hide your actual package/ classnames. Other features like init parameters and filters are also not possible in this case.
This is why you should NOT use the Invoker servlet. Even the Tomcat FAQ says you should not.

Got RuntimeException when using with Javascript
I am trying to configure Portal to use DHTMLX Grid Javascript. I configured Render Dependencies as per http://download.oracle.com/docs/cd/E13218_01/wlp/docs102//clientdev/setup.html#wp1020281 guideline.
My path to the javascript is WebContent | dhtmlx | codebase | javascrpit.js files here
The portal and portlet are at WebContent root folder.
My .dependencies file looks like this:
<render-dependencies>
<html>
<links>
<search-path>
<path-element>../dhtmlx</path-element>
</search-path>
<link href="dhtmlxgrid.css" type="text/css" rel="stylesheet"/>
</links>
<scripts>
<search-path>
<path-element>../dhtmlx</path-element>
</search-path>
<script type="text/javascript" src="codebase/dhtmlxcommon.js"></script>
<script type="text/javascript" src="codebase/dhtmlxgrid.js"></script>
<script type="text/javascript" src="codebase/dhtmlxgridcell.js"></script>
</scripts>
</html>
</render-dependencies>

Edited by: user5767041 on Sep 25, 2009 1:52 PMHI,
what version of javascript your are using.
Try to use latest version of javascript where its can support for xhtml.
But looking at the error I dont think it would be issue with javascript it say some thing different.
can you be more brief so that it could be more clear for us.

Open and Close Popup With Javascript
Using Apex 3.2
I have probably done this loads of times in my old job, but do not have access to the code and today I just can't get it to work properly.
I have opened a pop up window with javascript
Now I need to close it and refresh the calling page, but only if it passes the validation on the popup.
I have a hidden item on my pop up called P7_FLAG.
I have a page process after validation that sets P7_FLAG to (only set to 1, if passes validation).
I also have a SUBMIT button.
So once I click my SUBMIT button the page should look at the validations, if ok, set P7_FLAG to 1, then close the popup and refresh the calling page.
My current javascript look like this
<script type="text/javascript">
function saveChanges(){
doSubmit('SUBMIT');
var test = $x('P7_FLAG').value;
if(test == '1')
window.close();
window.opener.doSubmit('REFRESH');
</script>On my button
javascript:saveChanges();The problem is that I need to click the SUBMIT button twice.
First time it sets P7_FLAG
Second time it closes page and refreshes.
I have probably made some basic error, but today I cannot see it.
Cheers
Gus
Edited by: Gus C on May 10, 2012 12:48 AM<script type="text/javascript">
function saveChanges(){
doSubmit('SUBMIT');
var test = $x('P7_FLAG').value;
if(test == '1')
window.close();
window.opener.doSubmit('REFRESH');
</script>javascript does not wait for the current action to complete and then perform the next line.
means in your function call
doSubmit('SUBMIT');is triggered and it carry on's to next line that is
$x('P7_FLAG').value;this will not be set because you are setting the value of P7_FLAG to 1 in plsql and trying to check in javascript, which will not work.
what you need to do is amend your js function like below
<script type="text/javascript">
function saveChanges(){
doSubmit('SUBMIT');
</script>create a page branch to procedure and make it conditional to when P7_FLAG = 1
and set the branch source to below
htp.p('window.close();');
htp.p('window.opener.doSubmit(''REFRESH'');'); -
Links that open a new window with javascript:void(null); do not work in 3.1
I've been noticing that any site I go to that opens content in a new window with "javascript:void(null);" will be ignored by Safari 3.1. The links work in Firefox and used to work in Safari as well. Any suggestions?
General rule of thumb in the Mac universe...
When Safari is updated most if not all third party add-ons break. That's because most don't play by the rules. The developer thinks they know how to do it better than Apple so they just do it their way. So the first rule of survival is to KNOW what you have installed on your machine at all times. Use something like textedit to create a document listing all of the third party stuff you have installed and religiously update the list. Second rule is to wait a few days before applying an update. Third rule is to visit your third party developers' sites and make sure their little gadget is compatible with the new Safari update.
Being aware of things will make life much easier for you in the long run. -
How to get real value from selectOneChoice with javascript?
Hi,
How to get real value from selectOneChoice with javascript? The event.getNewValue() only gets me the index of the selected item, not the value/title.
JSF page:
<af:resource type="javascript">
function parseAddress(event)
alert("new value: " + event.getNewValue());
</af:resource>
<af:selectOneChoice label="Location:" value="" id="soc4">
<af:clientListener type="valueChange" method="parseAddress" />
<f:selectItems value="#{Person.locations}" id="si7"/>
</af:selectOneChoice>
HTML :
<option title="225 Broadway, New York, NY-10007" selected="" value="0">225 Broadway (Central Office)</option>
<option title="90 Mark St., New York, NY-10007" value="1">90 Mark St. (Central Office)</option>
Thanks a lot.Something I was missing ,
You need to add valuePassThru="true" in your <af:selectOneChoice component. I have personally tested it and got the actual value in alert box. I hope this time you got the real solution. You can also test the following code by your end.
