java.lang.NoClassDefFoundError: com/sapportals/iviewserver/systemlandscape/

[Former Member]

Hi there,

I want to make use of the ISystemLandscapeService in my WD project. I added the .jar file. When I run the application I get the following error:

java.lang.NoClassDefFoundError: com/sapportals/iviewserver/systemlandscape/service/ISystemLandscapeService

Is that because of there is no portal sharing reference? Or is there some other cause.

Help needed.

Hi

Create a library project and add the jar to the project.And deploye it to the J2EE server.

And make the project as reference by right click project ->properties ->Web Dynpro References -> go to Library refernces tab and give the deployed library project name into that

Kind Regards

Hi,

Try to add the jar file like this.

1)Go to navigator

2)Copy the jar in the lib folder

3) Go to the properties of the project

4)Java build path>Add jars>Select the jar in the lib folder

Since its not able to find the jar at the runtime it throws the error like this.

Hi Vijayakhanna,

I did what you said. I don't get the error anymore.

I get another error: java.lang.ClassCastException

at this line: ISystemLandscapeService landscapeService =

(ISystemLandscapeService) WDPortalUtils.getServiceReference(ISystemLandscapeService.KEY);

What is wrong?

Any help is welcome.

Hi,

Check with the portal Sharing reference.

Hi Sandhya,

Hi Suresh,

This is not how you access the ISystemLandscapeService from a WD project.

Therefore you use WDPortalUtils.getServicReference(...)

I added to the sharing reference:

PORTAL:com.sap.portal.pcmbuildservice

PORTAL:sap.com/com.sap.portal.ivs.systemlandscapeservice.oldpcm

The sharing reference refers/is to a portal app. or api. Right? How can you know exactly the path of the sharing reference?

Sandhya

[vijayakhanna_raman]

Hi,

Yes. Sharing Reference refers to any portal application service. Service name is the application name. For ur case, try like this.

<b>PORTAL:sap.com/com.sap.portal.ivs.systemlandscapeservice</b>

Also add prtapi.jar as External Jar and check.

Hi VijayaKhanna,

I tried what you said. When I deploy I get a deployment exception:

: Clusterwide exception: server ID 163146250:com.sap.engine.services.deploy.exceptions.ServerDeploymentException: Application local/WebDynproFromUWL cannot be started. Reason: it has hard reference to resource com.sap.portal.ivs.systemlandscapeservice with type application, which is not active on the server

How can I see if an portal application service is active on the server?

Sandhya

[vijayakhanna_raman]

Hi,

I saw in some post that com.sap.portal.ivs.systemlandscapeservice.oldpcm

has deprecated and so instead we have to use com.sap.portal.ivs.systemlandscapeservice. But now I checked. Only com.sap.portal.ivs.systemlandscapeservice.oldpcm

is there. So try with this itself.

PORTAL:sap.com/com.sap.portal.ivs.systemlandscapeservice.oldpcm

Hi,

I tried that before, then I get a DispatcherException

com.sap.tc.webdynpro.services.sal.core.DispatcherException: Failed to start deployable object local/WebDynproFromUWL

How can I check if the portal application references exist in the portal and are active?

Hi,

If I remove all the portal sharing references, the

application works.

I need to refer to the portal application references. Because I need to read the system out of the ALIAS.

The thing lies in the portal application references.
