DynamicParameter

[Former Member]

Hello Gurus,

i am trying to do a very simple thing in Webdynpro but it seems to be more complicated than i thought.

I have a simple WebDynpro application embedded in a Portal page.

I am trying to pass 2 parameters (empno and empno1) through the URL which i would like to read it in my WebDynpro component.

The URL looks like this: <b>without URL encoding</b>

http://hq2302:50000/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fevery_user!2fUmesh!2fpage?...

The URL also looks like this: <b>with URL encoding</b>

http://hq2302:50000/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fevery_user!2fUmesh!2fpage%...

<b>In the WebDynpro component, i retrieve it using the following code:</b> String empNo=WDProtocolAdapter.getProtocolAdapter().getRequestParameter("empno");

msgMgr.reportSuccess("empno in overview is "+empNo);

String empNo1=WDProtocolAdapter.getProtocolAdapter().getRequestParameter("empno1");

msgMgr.reportSuccess("empno1 in overview is "+empNo1);

However, by this approach, i am only able to retrieve the value of the 1st parameter and not the second.

Note: I have tried all the approaches specified in the following doc......Unfortunately nothing works !!!!!

Can anybody please help.

I would appreciate if you could please send me the corrected URL (if it needs to be corrected) and/or the exact code, instead of pointing me to some other doc.

Very IMP: I have tested this both in EP6 as well as EP7.

Thanks a lot in advance,

Umesh.

Hi Umesh and Sandeep,

Both of u were not getting values because the method used was deprecated

Use the following code

WDProtocolAdapter.getProtocolAdapter().getRequestObject().getParameter("param1");

WDProtocolAdapter.getProtocolAdapter().getRequestObject().getParameter("param2");

It will return the values fro param1 and param2

Hi Sundeep,

Append url params as

"<i>ampersand</i><b>param1=sundeep<i></b>ampersand</i><b>param2=Sethi</b>"

instead of

<b>"?param1=sundeep</b><i>ampersand</i><b>param2=Sethi"</b>

because the url parameters starts from <b>?SAPtestId=...</b>

So only we have to append URL Param to SAPTestId as <i>ampersand</i><b>param1=..</b> instead of <b>?param1=..</b>

<b>Note:Since the symbol is not coming in the browser, I had used <i>ampersand</i>. Use the symbol instead of that in ur url</b>

Hi Fahad,

Thanks for your reply...but doing this gives a runtime error..

I did the following in my JSP

<iframe id="personaldetails" frameborder="0" src="/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fsundeep!2fjava_sap_com_webdynprocomp_com_ibm_wd_HelloApp<b>%26DynamicParameter%3Dsundeep%3D12998%26empno%3D11111</b>"

width="100%" height="1000" >

Note the things in bold...

Now when i ran the application it gave the following iview not found runtime error:

Portal Runtime Error

An exception occurred while processing a request for :

iView : N/A

Component Name : N/A

iView not found: pcd:portal_content/sundeep/java_sap_com_webdynprocomp_com_ibm_wd_HelloApp&DynamicParameter=sundeep=12998&empno=11111.

Exception id: 11:47_19/04/09_0006_14617650

See the details for the exception ID in the log file

Other suggestion will be highly appreciated.....

How did you do the encoding?

The cited article says:

1. We would like to pass two parameters to the Web Dynpro application associated to the NW04s Web Dynpro iView: objectInstanceID and viewMode.

2. The needed values are objectInstanceID=4711 and viewMode=simple

3. To ensure that all values are passed correctly (especially in cases where a value contains special signs like äü#/)(>;:§$)

you have to encode the values one by one

.

4.

After that you have to put all parameters together and encode this parameter string again

.

5. The encoded value is the needed parameter value of the DynamicParameter parameter.

Hello Armin,

I too have the same problem...Umesh is right ..I think there is a bug in the DynamicParameter approach when we try to pass 2 parameters...I had followed the algorithm u have mentioned and in this case it would be :

%3FDynamicParameter%3Dempno%3D1234%26empno2%3D4321

The above string is:

?DynamicParameter=empno=1234&empno2=4321

I had appended the encoded string at the end of the encoded iview URL

Using DynamicParameter we can pass only one parameter at a time...

Interestingly in the above case only the first parameter i.e empno whose value is 1234 is passed and the other is discarded....

Experts correct me if i am wrong and suggest the right approach..
