linking webdynpro applications

[Former Member]

hi,

we develop a roadmap-like wd-application.

Now we have to put a view before the roadmap on which the user must chose from 2 URLlinks where to go next.

The architecture of the whole concept is like this:

we built one wd-project which contains 2 applications with corresponding windows. the roadmap-window contains all the views for the roadmap - the URL-window only one view with the 2 links (some other stuff, too - means, we can't put this view in the roadmapwindow).

The whole webapplication is set up in an EP 6.0.

Now I don't know how to link from the first URLview to the roadmap-application. As URL I tried the EP-iview-preview URL, which is

"http://epserver:50000/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fBONDPortal!2fpoc!2fcom.bondportal.iViews!2fVorgangAnlegen"

this does not work...

I also tried the EP-iview-webdynpro contents url, which is: "local/RoadMap/Roadmap"

when clicking the actual link on the URL view I get a real link:

"http://epserver:50000/webdynpro/resources/sap.com/tc_wddispwda/global/SSR/local/RoadMap/Roadmap"

neither of the above works.

Can somebody please help out?

Thanks a lot in advance,

Matthias

You may have to use

WDURLGenerator.getApplicationURL(deployableObjectPart, urlParameters);

Refer this document.

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/webdynpro/in... in web dynpro.pdf

Hope this helps.

hi,

helpful link - thank you. still i don't really know what is the deployable objectpart. In your mentioned document it says:

<i>To trigger the default operation of a certain business object using the WDPortalNavigation service, you have to use one of the defined navigateToObject() methods. Depending on the signature used, the following parameters are available:

• system

You have to specify the system (alias) to which the business object is assigned. This is a mandatory parameter.

• businessobjType

You have to define the business object using this mandatory parameter.</i>

What I did so far was setting up a string context variable called URL, which shall contain the URL to the next iview. I tried this:

<i>

wdContext.currentContextElement().setURL(WDURLGenerator.getApplicationURL("local/Roadmap/Roadmap"));

</i>

but i run into error "the method getApplicationURL(String String) in the Type WDURLGenerator is not applicable for the arguments (String)".

Do I somehow have to tell my WD to use the WDPortalNavigation?

Thank you in advance,

Matthias

Hi,

Suppose you have two applications then you can create the url using the WDUrlGenerator.

wdThis.wdGet<ComponentContoller>().wdGetAPI().getComponent().getDeployableObjectPart();

This would return the deployable object part for the given component.

hi,

first, my java is very basic.

so yes - i use two applications and one wdcomponent.

But how do i assign the URL to my UI-Element LinkToUrl?

look:

this works:

wdThis.wdGetRoadmapController().wdGetAPI().getComponent().getDeployableObjectPart();

But already this does not work:

WDURLGenerator.getApplicationURL(wdThis.wdGetRoadmapController().wdGetAPI().getComponent().getDeployableObjectPart());

how do I have to build it all together?

thanx once more,

matthias

Hi Noufal,

if i get this expression:

wdThis.wdGet<ComponentContoller>().wdGetAPI().getComponent().getDeployableObjectPart();

can i then assign the value of it to a context variable?

I thought I must use LinkToURL, which then may get the value of this deployable part - but i get converting errors: mismatch string to deployable...

So, if I get the deployableObjectPart - how can I store it?

I can't put it in a string variable.

Instead of

wdContext.currentContextElement().setURL(
  WDURLGenerator.getApplicationURL(
    "local/Roadmap/Roadmap"
  )
);

try

wdContext.currentContextElement().setURL(
  WDURLGenerator.getApplicationURL(
    "local/Roadmap", "Roadmap"
  )
);

WDDeployableObjectPart currentAppPart = wdThis.wdGet<ComponentContoller>().wdGetAPI().getComponent().getDeployableObjectPart();

String a=WDURLGenerator.getApplicationURL(currentAppPart);

Simply wdComponentAPI.getDeployableObjectPart() should also work.

dear contributors,

so far I tried this in the wdDoInit() method of the view, where I finally want to link to:

WDDeployableObjectPart currentAppPart = 
	wdThis.wdGetRoadmapController().wdGetAPI().getComponent().getDeployableObjectPart();
	try {
		String URL = WDURLGenerator.getApplicationURL(currentAppPart);
		wdContext.currentContextElement().setURL(URL);
	} catch (WDURLException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}

this gives no sysntax error in NWDevStudio.

then I put the String URL in the context and mapped it to the controller context. Then from my starting application I want to use the Context URL to pass it on to my LinkToURL UI-Element on the starting view.

when I deploy the application with the code above, i get:

<i>WDIllegalArgumentException: Invalid deployable object part type: Component</i>

what went wrong this time? Do I have to put <i>WDDeployableObjectPart currentAppPart</i> elsewhere?

Create an outbound plug in the plugs tab of the view.

then wdthis.wdfire<plugname>(url);

Hope that would work

[Former Member · Accepted solution]

I doubt the plug thing will work - because I have one wdcomponent - two applications with their own viewsets.

In the application with the starting view i need the addressURL of the next view from another application.

How is that achieved?

Or is that somehow aesier if you create two different wd-projects?

Still the point is, that i put the "getDeployableObjectPart" in the others application startview, which is the one, where I want to link to. When I deploy that application (with the "getDeployableObjectPart") I get the above runtime error.

Never thought that it could be so hard to link two webdynpros!

Hi,

Use

wdThis.wdGetAPI().getComponent().getApplication().getDeployableObjectPart() .Then get the URL using getApplicationURL.

This will give the current applications URL>

In your case when u need the URL of another application

String depObjectName =

wdComponentAPI.getDeployableObjectPart().getDeployableObjectName();

WDDeployableObjectPart depObjectpart =

WDDeployableObject.getDeployableObjectPart(

depObjectName,

"<application name u want to navigate to>",

WDDeployableObjectPartType.APPLICATION);

String a = WDURLGenerator.getApplicationURL(depObjectPart) ;

Fire exit plug with this String a as the argument.

Just fire the plug with the Url as a String within.

It will call the second application. That how we do inter-app navigation in webdynpro.

Revert for further clarification

Hi Bharathwaj R, Noufal et al,

thank you for the input - I shall check your proposal.

Right now I implemented a solution, that uses portal navigation like this:

WDPortalNavigation.navigateAbsolute(
	  "ROLES://portal_content/BOND/poc/com.bond.iViews/VorgangAnlegen",
   	
		WDPortalNavigationMode.SHOW_INPLACE,
		(String) null,
		(String) null,

		WDPortalNavigationHistoryMode.NO_DUPLICATIONS,
		(String) null,
		(String) null,
		"firstName=Matthias&lastName=Kasig");

you shall find the tutorial on http://help.sap.com/saphelp_erp2004/helpdata/de/c6/21fc3f82c2e469e10000000a155106/content.htm

here it says you have to declare ep-<i>pages</i> for this goal. apparently it also works with iviews! Concerning pages, which carry the iview I had problem with the layout... (i chose layout: one column - standard) and got a layout which covers the whole width of the screen but is captured in a scrolling frame which is like 4 cm deep, although i set the window height to 800 px.

help in this case is also welcome.

thank you again,

matthias

Hi,

wdDeployableObject will give us the object.To get the URL application we have to make use of URLgenerator's function getApplicationURL which returns a String for a particular deployable object.

Chk this ..

Hi,

Does getApplcation URL throw any exception.Are u printing the String .Print the string which the function applcation URL returns.It should be the application URL
