Hi All,
In CE7.2 portal application we are getting the below exception while accessing some of the Development components related to JCO. This issue is facing every server restart and after sometime this will be resolved automatically.
When we checked the JCO destinations, they are able to ping successfully.
[EXCEPTION]

Hi,
Please configure your SLD. Your SLD holds the system definition. Define a SAP WebAS abap system and then try to create a Metadata connection using WebDynpro content administrator. Now you will be able to see the msg server defined in the dropdown. Also ensure that you have the message server entry in your services file.
Refer these links for SLD
