Dear Sndeep,

Please check the [Inter Application Communication and Navigation (Design Time) in WebDynpro|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a0ae5f90-1679-2c10-4183-8c64cf932088?quicklink=index&overridelayout=true]

Refer to [Web Dynpro Java in the Portal |http://help.sap.com/saphelp_nw70/helpdata/en/d0/f6584289e59041e10000000a1550b0/content.htm]

Hope it will helps

Hi,

Please follow the below process for passing data between two webdynpro applications using portal eventing.

Step1:-

Webdynpro Application 1 (Iview1)

Create an input field bind a context variable and have a button and write the following code in the button onaction.

public void onActionOK(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
  com.sap.tc.webdynpro.clientserver.event.api.WDPortalEventing.fire("urn:com.sap.tc.portaleventing.example","show",
				wdContext.currentContextElement().getHi());
  }

Here Hi-->is the context variable binded to the input field.

Step2:-

Webdynpro Application 2 (Iview2)

WDDOINIT write the following code:-

com.sap.tc.webdynpro.clientserver.event.api.WDPortalEventing.subscribe("urn:com.sap.tc.portaleventing.example","show",wdThis.wdGetRaiseFireAction());

While creating the action it should have the following 3 parameters.

1.dataObject-->Type String

2.namespace-->Type String

3.name-->Type String

Your action code should look like something below.

 public void onActionRaiseFire(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String dataObject, java.lang.String namespace, java.lang.String name )
 {
    wdComponentAPI.getMessageManager().reportSuccess("Value in the input field"+dataObject);
  }

Note:-

1.Make sure your using portal along with domain

Eg:-http://<hostname>:<port>:50000/irj/portal--->wrong

http://<hostname>.<domain>:<port>/irj/portal--->right

2.EPCF level should be 1.

3.Check whether both applications run on the same domain.Sometimes portal eventing does not work between cross domain applications.We should do domian relaxing in order to achieve this.

Thanks & Regards,
