Retrieve HTTP Session attribute value

[former_member317512]

Hi,

Using Web Dynpro for Java, how can I retrieve from Http Session one attribute setup by a standard Java app?

The value was setup like this:

IPortalComponentSession compSession = request.getComponentSession();

//where IPortalComponentRequest request

javax.servlet.http.HttpSession thisHttpSession = null;

thisHttpSession = compSession.getHttpSession();

thisHttpSession.setAttribute("myvalue","test");

Hi

Were u able to retrieve the value as I have a similar requirement and I am unable to get the parameter value using protocoladapter.

Thanks

Seems that there is no bridge between Web Dynpro iView and Standard Portal iViews, ways of retrieving Session variables from one to another.

Therefore to solved my issue creating Web Dynpro iView that save the needed value using:

WDScopeUtil.put(WDScopeType.CLIENTSESSION_SCOPE,…)

and I can retrieved them from other Web Dynpro applications using the: WDScopeUtil.get(WDScopeType.CLIENTSESSION_SCOPE,..)

Thank you all for your help.

Thanks, Corina. That will help us a lot. An earlier post by Bertram seemed to suggest to use storing in a database.

No, this doesn’t work.

Where can I store then global name/values that need to be used by other Web Dynpro iView and Standard Portal iViews?

Thank you

Corina,

The WD framework has been designed to store the session data in the Component controller. Map your views data to the Component controller and access the component controller's data in the second view by making similar mapping. For more details refer to the following tutorial.

Hi,

Make use of the WDScopeUtils.

Hi,

You can retrieve the value as being told by Chintan and store in the context of your component controller if the same needs to be shared amongst different views.

Corina,

I am not sure if you can get HTTP session attributes but you may give this a try:

IWDProtocolAdapter protocolAdapter = WDProtocolAdapter.getProtocolAdapter();
IWDRequest request = protocolAdapter.getRequestObject();
String paramValue = request.getParameter("<atributename>");
