How to catch URL parameter from Portal URL in Web Dynpro iView

Question

Hi All,
I have a web dynpro application running as a portal iView successfully. Now the client wants to make it internationalized with 7 languages. Currently they access the portal - and via role assignment they get to the portal tab with the wd iView. Now they want to send a parameter for the language key with the portal URL. So when they are typing in http://myportal.mydomain.com now they want to type in http://myportal.mydomain.com?sap-locale=de or so. My question is how can I catch this parameter in the WD application when it is running inside a portal iView? Is it at all possible?
I have written a very small application which is trying to catch a URL parameter named PARAM. The code I have written is the default one as below:
String paramValue = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("PARAM");
When I run the application standalone and add the PARAM=something in last of the URL I can catch it. But when I create an iView and while previewing it I add the same PARAM value it is coming as null all the time. Same when I add this iView to a role and show it via role assignment in protal. Please help to let me know how to achieve this. I think if I can read the parameter value from Portal URL in the WD iView - then I can set it as the default locale of the application and then show language specific file to achieve internationalization.
Your urgent help will be highly appreciated.
Warm Regards,
Shubho

Hi Shubhadip
Even if you get the parameters, how do you internationalize your application? Are you not following the standard way as described in the following link. In this case you never need to capture any such parameter. This is done by the WD runtime automatically .
<a href="http://help.sap.com/saphelp_erp2005/helpdata/en/f4/d95664da179b4db731e21c2e470b72/frameset.htm">Internationalization of WD projects</a>
You can retrieve application parameters specified at the creation of iview by "adding parameters(with the same name as in iview application parameters) to the default plug of the Component Interface View of the WD application". "onDefaultPlug" method of the interface view controller you get these values as parameters, which you can save in the context node of component controller for later use.This is guaranteed to work.
But again this is not what you want exactly. You want the user to specify the value at runtime. If you have just 7 languages, you can create 7 set of iviews with different application parameter value indicating language key, and assign to 7 different set of roles, each representing one set of users with common language.
I hope you find a solution.
