Any ideas?

Hi

The reason for the error was that I have created a JCo Destination when I created the technical system.

When I removed it, and went to the webdynpro admin, I was the able to create Jco Destinations and it all works just fine.

Case solved

Could you please explain how you did this?

Thanks,

Eric

We had a similar problem over here.

The solution:

http//<yourserver>/sld

Go to content maintenance

Select subset: landscape definition

Class JCO message server destination & JCO application server destination

Delete everything that doesn't belong there.

I have looked at your answer and seen the link you are refering to, but I still can not perform the creation of the JCo Destination

[Former Member]

Hi,

If you want to create a JCO destination follow the link

http://<your server>:<port>/index.html->Web Dynpro>Content Administrator-->create JCO Destination .

Hope this helps you...

Hi,

Have you configured your SLD? Check out or search for "com.sap.tc.webdynpro.serverimpl.wdc.sl.SystemLandscapeFactory.checkStatus" in the SDN forums.
