Input type="hidden" value="....a chain of rubbish letter......"!!

I use the browser view source function to see the html generated by jsf, and always see something like the following:
<input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="8EgC7hvJoXWgMHaUZxk5rx66APlnNueyP32ajDxbvc/i5akMf2jX5ZGyBjrnsmcbFDLXCaS8cHN169OeG5kDXxvWNcBMTAigJiokZI5Ne66G0/CILkEquml3xSn+jI4+HDkEeDEBtmlPDjjFJyOcOmZ+87klHuSTgAe5P6mMDOQOqrH0Pj9yl+

Why are you always so negative in your questions/postings? In every post you're just complaining and throwing around with too much exclamation marks. It's getting annoying. You risk to become placed in the ignore list.
Anyway, you have configured JSF to use client side state saving. This isn't a default setting.

Upload file input type="hidden" to server

I have a file that is on a user machine. The file is always in the same location. I want to have the user click on an upload button without selecting a file and have it sent to the server for processing. I have tried to use <input type="hidden" name="fileupload" value="c:\filepath">. When I run it this way I get no file found. Please help!

I am sorry, I will move it. Didn't notice it was in Acrobat, I was wanting Coldfusion.
Edit: Since I am unaware of how to move it I'm just going to mark it as answered.

thanks..I've used a netui:anchor tag with a nested netui:parameter tag thatpassed
the
"hidden" field to an action in the pageflow. In the pageflow, use the
getRequest
method as below...
IN JSP:
<netui:anchor action="toNextInCatalog"><%=category.getName()%>
<netui:parameter name="categoryName" value="<%=category.getName()%>"></netui:parameter>
</netui:anchor>
IN PAGEFLOW:
String catName = this.getRequest().getParameter("categoryName");
hope this helps,

There is a <netui:hidden> tag which is intended to have an equivalent to the HTML
hidden fields. However I couldn't achioeve to set a defaultValue ([dataInput="dataInput"].

Why do I have this HTML coding in all my posts on web forums nput id="mac_address" type="hidden" value="" /

Whenever I use internet forums such as the eBay discussion boards or RV.net, I have this string of HTML code automatically and without my knowledge entered in to the text box on the forums.
What led to this activity and how do I stop it from occurring?
nput id="mac_address" type="hidden" value="" /

It might be an add-on that is misbehaving. You can try disabling add-ons individually to see which one is responsible. You can also reset Firefox, while keeping your personalized data, like history, bookmarks, passwords, etc: [[Reset Firefox – easily fix most problems]]

Encoding URL Query String .

Suppose my url is
Now i dont want my url to look exactly like this but instead of these alpabets abc some special charaters should appear on the querry string in url .
If any body could help please .
Thanx in advance .

Don't be silly, of course you can! You just need a little JavaScript.
Somewhere in your document header put a short script like this:<SCRIPT>
function doPost(val1,val2,val3,val4){
   var f = document.formName;
   f.FirstVal.value = val1;
   f.SecVal.value = val2;
   f.ThrdVal.value = val3;
   f.FrthVal.value = val4;
   f.submit();
</SCRIPT>Your form will look something like this:<FORM NAME="formName" METHOD=POST ACTION="some.action">
<INPUT TYPE=HIDDEN NAME="FirstVal" VALUE="">
<INPUT TYPE=HIDDEN NAME="SecVal" VALUE="">
<INPUT TYPE=HIDDEN NAME="ThrdVal" VALUE="">
<INPUT TYPE=HIDDEN NAME="FrthVal" VALUE="">
</FORM>And your links will look something like this:<A HREF="javascript:doPost(1,2,3,4);">Link1</A>
<A HREF="javascript:doPost(3,4,5,6);">Link2</A>
<A HREF="javascript:doPost(4,5,6,7);">Link3</A>

How to access FlashVars or URL Query String

I am a bit of a rookie with Flash/AS3 and I need help trying to access FlashVars or URL in Object/Embed tags. I've searched in the Internet and the forums but cannot get my head around how to implement this. Here is my example.
1) ACTION SCRIPT - I have created a simple flash banner with clickable button (sparkle) with a mouse down event.
The action script (AS3) for the button is the following:
sparkle.addEventListener(
    MouseEvent.MOUSE_DOWN,
    function(evt:MouseEvent):void {
        var url:String = "http://www.[site_url].com/as/img.cfm";
      var request:URLRequest = new URLRequest(url);
        var variables:URLVariables = new URLVariables();
        variables.gphc = "382";
        request.data = variables;
        request.method = URLRequestMethod.GET;
      navigateToURL(request);
     *** the core issue to resolve is how to make the line above (variables.gphc = "382";) to be set dynamically. I would like for the variable to come from the FlashVars or the URL vars
2) OBJECT/EMBED - my object/embed code with include FlashVars and URL Query String
<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" ID="bannerAD" WIDTH="728" HEIGHT="90">
     <PARAM NAME="movie" VALUE="http://www.[site_url].com/images/imgs/flash_ad.swf?gphc=382">
    <PARAM NAME="quality" VALUE="high">
    <PARAM NAME="bgcolor" VALUE="#FFFFFF">
    <PARAM NAME="FlashVars" value="gphc=382" />
    <EMBED src="http://www.[site_url].com/images/imgs/flash_ad.swf?gphc=382" quality="high"WIDTH="728" HEIGHT="90" TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" FlashVars="gphc=382" />
</OBJECT>
Questions that I need answered ... How do we access the FlashVars or the URL Query String? I have found many references to loaderInfo but no clear way to implement that I'm able to understand. So if the loaderInfo is the key, where do I add in the loaderComplete() function into my action script above in #1?
function loaderComplete(myEvent:Event)
var flashVars=this.loaderInfo.parameters;
gphcTextField.text=flashVars.gphc
this.loaderInfo.addEventListener(Event.COMPLETE, loaderComplete);
Any help is much appreciated.

Thank you for your input. I implemented your sugguestion in the following way without any success. Notice below in the addEventListner that I have added the snippet of code. Is this a good place (correct place) to set the local_var? I did confirm that the FlashVars and URL variables were set.
sparkle.addEventListener(
     MouseEvent.MOUSE_DOWN,
     function(evt:MouseEvent):void {
         var url:String = "http://www.[site_url].com/as/img.cfm";
         var request:URLRequest = new URLRequest(url);
         var variables:URLVariables = new URLVariables();
         var local_gphc:String = LoaderInfo(this.root.loaderInfo).parameters.gphc;
         variables.gphc = local_gphc;
         request.data = variables;
         request.method = URLRequestMethod.GET;
       navigateToURL(request);
Thank you for your help.

URL query string block?

I was asked recently if there is a way to "block" the potential for someone to hijack a SWF by spoofing a variable via a URL query string.
For example, if there was a path variable hardcoded in the SWF that is pointing to data XML file, but someone found your path variable and typed in:
http://www.mysite.com/myFlash.swf?dataFile=maliciousdata.xml
That could change the variable in the SWF correct? Is there a way to block this behavior? Maybe a trick? Was thinking of delaying the declaration of the variable in the SWF in order to "void" anything coming in via the query string but want to know if there are other methods that could be used.
Thanks!

Hi,
in the old (AS1) days, url variables could become program variables. With AS3, you need to specifically retrieve them from an object
Of course, if you create your swf to do that (perhaps to see different data files during testing), someone else could abuse the feature

Howto read url query string? Help :(

Hi everyone, I am trying to read the query string from within an applet loaded from a URL. I am loading netscape with the following URL
"http://localhost/mypage.html?param1=help"
I am using code:
System.out.println(getDocumentBase().getQuery());
and all I am getting is a null?
This works with appletviewer so could someone tell me what is going on. I have searched the forum but it seems no answer yet exists for this. Perhaps its not possible?
Info:
OS: Redhat Linux 8
java version "1.3.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-b02)
Java HotSpot(TM) Client VM (build 1.3.1_02-b02, mixed mode)

hi,
can it be that there is a problem with netscape?
it would suggest to try on ie, but you use linux and i dont think theres an ie-version for linux available ;P
i would try it on a different browser like opera or something.
thats my suggestion.
hope this helped

Include XML payload as URL query string

Hello Gurus -
I have a business requirement that I'm hoping you all can help me with:
Scenario: Send XML message from SAP XI to a third party system via the Receiver Plain HTTP Adapter
I need to include the actual XML message as a query string in the target URL at the time of posting. The content of the XML message is determined within XI message mapping and will not be known until runtime, so the URL determination will need to be dynamic.
For example - a target URL with the "xmldata=" query string:
http://server01/receiver.asp?xmldata=<?xml version="1.0" encoding="UTF-8"?><headertag><tag1><value1></tag1></headertag>
Does anyone know how to do this - Is there some communication channel configuration and/or programming that would work?
Thanks to all!
Chad

Hi,
This is very similar to our scenario. By manipulating some of the Plain HTTP Adapter parameters, my colleague was able to post using xmldata. He set content type to text/plain then set the prolog to xmldata=. Let me know if this worked.

CiscoIPPhoneExecute with URL query strings

Has anyone successfully used the CiscoIPPhoneExecute xml object with URLs that contain query strings? Specifically, I'm wondering how to pass query string values that include spaces.
I'm able to successfully execute a URL such as:
http://<webaddress>/PushPage.asp?Field1=Value1&Field2=Value2
However, when I try to execute a URL like:
http://<webaddress>/PushPage.asp?Field1=Value with space&Field2=Value2
The phone displays an error message that says "Not Available", and the url that is pushed never gets executed.
I have tried representing spaces in the query string values using both the conventional "+" symbol, and I have also tried using "%20". Neither of these escape sequences seems to work.
Thanks for any advice.
-Mike

Thanks for the response. As I stated above, I know that ampersand (&) must be escaped, and I am properly escaping that character in the XML packets. I'm not having any problems pushing URLs that contain ampersand.
What I can't figure out is how to push URLs with *SPACES* included in the query string values. Please see the example URLs I posted in my original message, specifically the second URL. Again, I omitted the necessary ampersand escape sequence there for clarity.

Hi Das,
HttpServletRequest Object contains many methods like
HttpServletRequest servletRequest = request.getServletRequest();
servletRequest.getRequestURL();
servletRequest.getQueryString(); -->
servletRequest.getParameter();
servletRequest.getProtocol(); etc..
Hope this helps..

owa_util.get_cgi_env('QUERY_STRING')Regards,
Jari

You'd know this better than me - but I seem to recall there are 2 Oracle sessions involved in normal page processing - one for the request and one for the response. wwv_flow.show seems to correspond to the response session, not the request session (that might have the env variables you're looking for). Could that explain what you're seeing?

HTTP Sender Adapter - URL / Query String - Posting problems ?

Hi All,
Scenario: Partner sending order request via HTTP adapter to XI
I have configured my scenario and this is a sample URL I gave to Partner but when they try to post, they get "Connection Failed" error.
http://server.cmpny.com:1234/send/test/message?
service=Send_Order
&namespace=urn%3Asap-com%3Adocument%3Asap%3Aidoc%3Amessages
&interface=ORDERS.ORDERS05
&party=ABC&qos=EO/
Party Name : ABC
Service : Send_Order:
Interface: ORDERS.ORDERS05
Namespace: urn:sap-com:document:sap:idoc:messages
This partner has been "successfully" exchanging data for other messages using the same hostname/userid/passwd, so is there any problem my URL encoding ?
Any help is appreciated
Bob

Hey
i m not sure how u generated the URL for the scenario but the best approach would be to use the following HTTP test tool for it
/message/266750#266750 [original link is broken]
just use the code given by Mr.Stefan Grube .
secondly instead of host name ,give the IP address of the XI server.
Thanx

Project server URL Query strings

Hello,
I'm trying to auto populate Project Server with project details, but I can't find the strings for name and Descriptions,
Trying: http://servername/pwa/Project%20Detail%20Pages/ProjectDetails.aspx?NewProject=yes&EntProjectTypeUID=8e006270-7ea1-e311-93f7-00155d01206a
using &name=test
Didn't fill in the name
any Idea.
Thanks
tony
Antoine AL Ibry

Antoine,
A little more detail would help. What are you using actually to auto-populate?
The Name, and other properties in Project Server are "fields", and not page properties (not sure if I am using the right terminology here, but hope you get the idea).
My guess is that you will have to use one of the PSI methods to do this.

Also you might get better answers if you post to the Project Customization and Programming forum.
