What is the procedure to pass parameters via POST using WebDynpro ?
I am required to pass XML Data via POST.
I have gone through the following :
a) http://help.sap.com/saphelp_nw04/helpdata/en/9e/a073001903c9419592b14c2aa63669/content.htm
b) Inter Navigation Application in Web Dynpro
However, I could not find any reference to do the same via POST.
Can anyone throw light on the same ?

Passing Parameters via Post Method from Webdynpro Java to a web application

Hello Experts,
I want to pass few parameters from a web dynpro application to an external web application.
In order to achieve this, I am referring to the below thread:
HTTP Post
As mentioned in the thread, I am trying to create an additional Suspend Plug parameter (besides 'Url' of type String) with name 'postParams' and of type Map.
But when I build my DC, I am getting the same error which most of the people in the thread have mentioned:
Controller XXXCompInterfaceView [Suspend]: Outbound plug (of type 'Suspend') 'Suspend' may have at most two parameters: 'Url' of type 'string' and 'postParams' of type 'Map'.
I am using SAP NetWeaver Developer Studio Version: 7.01.00
Kindly suggest if this is the NWDS version issue or is it something else that I am missing out.
Also, if it is the NWDS version issue please let me know the NWDS version that I can use to avoid this error.
Any other suggestion/alternative approach to pass the parameters via POST method from webdynpro java to an external web application apart from the one which is mentioned in the above thread is most welcome.
Thanks & Regards,
Anurag

Hi,
This is purely a java approach, even you can try this for your requirement.
There are two types of http calls synchronous call or Asynchronous call. So you have to choose the way to pass parameters in post method based on the http call.
if it is synchronous means, collect all the values from users/parameters using UI element eg: form and pass all the values via form to the next page is nothing but your web application url.
If it is Asynchronous means, write a http client in java and integrate the same with your custom code and you can find an option for sending parameters in post method.
here you go and find the way to implement Asynchronous scenario,

Calling a new browser window with WD Abap and passing data via POST

Hi there,
does anybody know whether passing data via POST method is possible when opening a new browser window from within a Web Dynpro Component? In my case I use method IF_WD_WINDOW_MANAGER->CREATE_EXTERNAL_WINDOW for opening a new browser window. Now I want to pass a big amount of data which is only possible via POST method. How can I achieve that or is it not considered inside the Web Dynpro Framework?
Kind regards,
Albert

Hi Priya,
can you please explain a little bit more what you mean? I didn't get it..

Parameters via POST using WebDynpro ?

Hi all,
I need to pass parameters between two web dynpro applications of length bigger than the limit that HTTP GET method allows.
I'm thinking to use HTTP POST method or HTTP Session to share data.
Anybody knows if web dynpro provides a way to handle this?
Thanks in advance,
Diego.

Hello Diego,
From where are you getting startup parameters initialy? Or are they hardcoded?
More information about "transient attributes" https://media.sdn.sap.com/javadocs/NW04/SP9/ume/com/sap/security/api/IUser.html (methods getTransientAttribute and setTransientAttribute). The main feature of transient attributes is non-persistance. They are not stored.

Long parameters via POST

Is there any way to pass long text parameters with POST method instead of sending it part of url ..
Either by using f? format url ..something like this ..
<form name="input" action="http://ApexServerName:Port/apex/f" method="POST">
<input type="hidden" name="app" value="118"/>
<input type="hidden" name="page" value="1"/>
Long text : <input type="hidden" name="F1_MYLONGTEXT" value="My long text"/>
Long text2 : <input type="hidden" name="F2_MYLONGTEXT" value="Another long text"/>
<input type="submit" value="Submit" />
</form>
OR by using wwv_flow.accept directly -
<form name="input" action="http://ApexServerName:Port/apex/wwv_flow.accept" method="POST">
<input type="hidden" name="p_flow_id" value="118"/>
<input type="hidden" name="p_flow_step_id" value="1"/>
<input type="hidden" name="p_request" value="CREATE"/>
Long text : <input type="hidden" name="F1_MYLONGTEXT" value="My long text"/>
Long text2 : <input type="hidden" name="F2_MYLONGTEXT" value="Another long text"/>
<input type="submit" value="Submit" />
</form>
(Problem with this approach is that wwv_flow.accept procedure accepts only internal name of the items like p_t01 etc and not item name F1_MYLONGTEXT defined on the page).
Will any of these work ? Is there anyway to do this ?
I have a html form with some text area.. when user clicks on submit I want it to send that to an apex page(form).
Please advise.

hi,
You can use that item value directly to other page. Just set the save session state to be checked for that page which pages item you used.
Thanks,

Calling a function and passing parameters via Variables

I've got an XML file that is loading in data and is calling functions.
I've figured out how to call the methods from classes with variables set from the XML file:
var functionToCall:String = xml.functions.func[0].to_fire.toString();
myClass[functionToCall]();
This calls the function perfectly.
I was wondering if there is anyway to pass parameters into the function as well through variables. Some functions may have no parameters, some functions could have 5... so the xml could be like this:
<functions>
   <func>
    <to_fire>function1</to_fire>
    <param>
     <value>true</value>
     <type>Boolean</type> 
    </param>
   </func>
   <func>
    <to_fire>function2</to_fire>
    <param/>
   </func>
   <func>
    <to_fire>function3</to_fire>
    <param>
     <value>false</value>
     <type>Boolean</type> 
    </param>
    <param>
     <value>My String Value</value>
     <type>String</type> 
    </param>
    <param>
     <value>10</value>
     <type>Number</type> 
    </param>
   </func>
</functions>
whats the best way to set something like this up?

how would I set something like that up?
in the class:
public function myFunction(_param1:String, _param2:Number):void {
then to call it, would ParamTypes be cast as an array or object or something?
var functionVariable:String = "myFunction";
myClass[functionVariable](??);
Or do I structure the XML file in some way to pass in the information?

Passing Parameters via OpenDocument URL to OLAP Analysis .amw

Hello together,
did anyone ever manage to successfully create an OpenDocument URL which passes parameters to an existing analysis workspace .amw?
We already linked to other .crp and BEx reports, but maybe .amw needs some special syntax..
I appreciate every hint
Thanks
CR Enterprise 4.0 SP2 in usage

Hi,
I can confirm: The situation for A-OLAP is the same as it was for Voyager.
Analysis, like voyager, supports outbound opendoc params (ie pass context to WebI/CR) but not inbound params. The only exception is that you can specify which Voyager workspace to open.
Voyager/analysis supports SAP connection parameters on opendoc, but this is a manual selection in prompts. You cannot programmatically set connection variables.
Today we also support "Jumplinks"... a feature in both Voyager and A-OLAP that allows contextual information to be passed to a pre-defined Crystal Report.
For BI4.1 (end 2012) SAP plans to make A-OLAP more open. This includes supporting SAP's Report-Report-Interface (RRI) and extending the OpenDocument parameters beyond just the workspace name that is supported today.

H

Passing Parameters via HREF link

Hello All,
I would like to pass a parameter to
a portlet using an:
<a href="portlet ?id=somevalue"></a>
I have searched the support groups and
found no answer except the often repeated
"Look at the Parameter passing Guidelines".
I have read the guidelines, looked through
the sample code and it still makes no
sense.
Seems like this would be an easy method
in the JPDK but I cannot get anything to
work that I have tried.
Thanks in advance for any help!

Could you install the sample portlets?
Besides the Parameter Passing Guidilenes article there's another one that might help you: "Understanding the Parameter Passing JSP Sample".
In the Training Center on the Community Home tab on Portal Studio, you find several online eClasses. The Building Java Portlets covers among others the parameter passing services. You can also download the example portlet.
If you're more specific what your problem is, we could provide you more help.

Passing Parameters via a button to a form

I have a form on a page based on a simple table with with the following fields
Code, Name and Address
I would like to put a button on this form which will then open a separate page which contains a form based on a different table which has the following fields
Code, Notes
When I click on the button I would like it to open the second form in edit mode if a record already exists.
So I need to pass the value of the code field in form 1 to query in the record in form 2.
I am very new to Apex and not sure how to do help much appreciated.

Hi,
As far as I know the default behavior is that if you pass the primary key to another form the record is opened in 'edit' mode, if you pass other fields than the PK to another form the form is opened in 'add new record' mode and the PK is generated when you save the record.
So if you can do a lookup of the PK before you go to the second form and call the form with this PK you should be able to edit.
Not sure if that answered your question though... :)

Passing parameters via command line

I've been asked to write a routine in LabVIEW that will control an
instrument. The only problem is that this routine will be called by a
different piece of software (3rd party software that we've bought)and
we need to pass a parameter. The source application will allow
switches in the command line, but that is the only way. Is there a way
Labview can accept this ??

Hi,
I'll mail you a vi to do this. Note that it will only work if you have an
application. (If not, you'll get the command line from labview...)
Regards,
Wiebe.

How does customization form pass parameters?

I need to create my own customization form so it can include linked LOVs and was wondering how the default customization form passed the LOV values back to the calling component.
I put two copies of the same report on a page and called the customization form for each report selecting different LOV values. Since each report displays the correct results based on the LOV, I assume page parameters are not being used and neither is p_arg_values/p_arg_values.
Can anyone tell me how this information is being passed to the individual reports?
Thanks, Larry

Sharmila,
I guess I'm confused, the parameters that are selected on the Customization screen are persistent across different login sessions.
Is is my understanding that passing parameters via p_arg_names/p_arg_values on the URL would not carry over from one logon to another or even allow me to navigate to another page and then back to the "customized" screen and still have the customizated values applicable?
Are you saying that once I call a page and pass a name/value parameter pair to the page, that the paramter values remain in affect for subsequent calls to the same page where the name/value pair isn't being passed?
Doesn't the customization screen use the wwpre_api_name and wwpre_api_value methods to pass parameters to components located on a page via the user preference storage?
When I look at the URL associated with the customization link on my portlets I see the preference_path being passed to the customization form.

Passing parameters in jsp

Hi friends,
I am very new to oracle pdk. But unfortunately i was assigned to a small pdk development using jsp.
How can i send parameters in the Oracle jpdk multipage sample portlet .
The first.jsp says ,
<%
PortletRenderRequest prr = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
NameValuePair[] linkParams = new NameValuePair[1];
linkParams[0] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, "next_page"), "/htdocs/multipage/second.jsp");
%>
<center>
Hello, this is the first page<p>
<%=UrlUtils.constructHTMLLink(prr, UrlUtils.PAGE_LINK, "second page", "", linkParams, true, true)%>
</center>
Now where should i add the parameter which i have to send to the second page named second.jsp.
In the same way how to receive the parameter values in the second.jsp file, the second.jsp is listed here as below.
<%
PortletRenderRequest prr = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
NameValuePair[] linkParams = new NameValuePair[1];
linkParams[0] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, "next_page"), "/htdocs/multipage/first.jsp");
linkParams[1] ="a=hello";
%>
<center>
Hello, this is the second page<p>
<%=UrlUtils.constructHTMLLink(prr, UrlUtils.PAGE_LINK,
"first page", "", linkParams, true, true)%>
</center>
Please write to me an example in detail.
Matter is very urgent.

I just recently put a set of helper classes on my knowledge exchange site specifically to help with passing parameters via the url.
http://portalstudio.oracle.com/servlet/page?_pageid=2106&_dad=ops&_schema=OPSTUDIO&_type=site&_fsiteid=233&_fid=433232&_fnavbarid=180376&_fnavbarsiteid=233&_fedit=0&_fmode=2&_fdisplaymode=1&_fcalledfrom=1&_fdisplayurl=
I called it Portal Tools. It includes usage documentation.
but, to stick with the code example you provided,
Technically, you can pass parameters at least three different ways:
-Using portal's parameter-event processing (portlets interact with portal for parameters)
-Using qualified parameter names (portlets only see "their" parameters)
-Using unqualified parameter names (portlets are responsible for unique names, name collisions, etc)
I would generally shy away from the unqualified parameter method; it was put in to support older versions of portal.
The example you provided currently uses qualified parameters, so I will answer with that method.
To add a parameter "a" with a value of "hello",
change the setup of the link parameters in first.jsp to this:
NameValuePair[] linkParams = new NameValuePair[2];
linkParams[0] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, "next_page"), "/htdocs/multipage/second.jsp");
linkParams[1] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, "a"), "hello");
note that in the definition line, you must allocate space for EXACTLY how many parameters you are using (2 now, rather than 1). Then in the assignment lines, it is using java standard ZERO based indexing, so the new second parameter is at index 1.
to get (and display) the parameter in the second.jsp page, you would include something such as this:
Parameter "A" contains a value of <%= prr.getParameter("a") %>.
note how you just ask the PRR for the parameter with the unqualified name.
The "next_page" parameter is defined (in the provider.xml) to be used by portal to manage page flow and display. That is why you only have to set the "next_page" parameter.
I hope this helps.
