Cannot create/maintain JCO connection : NullPointerException in SLD

[former_member584750]

When I want to create a new JCO connection in SLD (via WebDynpro->Content Administrator) , I get an exception :

java.lang.NullPointerException

at com.sap.tc.webdynpro.serverimpl.wdc.sl.SystemLandscapeFactory.checkStatus(SystemLandscapeFactory.java:991)

at com.sap.tc.webdynpro.services.sal.sl.api.WDSystemLandscape.checkStatus(WDSystemLandscape.java:469)

at com.sap.tc.webdynpro.tools.sld.NameDefinition.updateJCODestinations(NameDefinition.java:285)

at com.sap.tc.webdynpro.tools.sld.NameDefinition.updateNavigation(NameDefinition.java:250)

at com.sap.tc.webdynpro.tools.sld.NameDefinition.wdDoInit(NameDefinition.java:157)

...

Because the following document "[Adaptive RFC Troubleshooting Guide|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d0019b1a-775f-2910-beb8-d81f27d0d8d0]" suggests that the problem could be an incomplete JCO connection definition, I removed all other existing connections (it's a sandbox system), but this action has not solved the problem.

I also get the message "Exception while getting JCo Clients Failed to get list of defined JCO clients for deployable object 'sap.com/spider_search' " when the Content Administrator screen is displayed.

Any idea of what is missing ?

Thanks,

Eric.

As I want to define a connection to an ABAP back-end, to call a BAPI from a Guided Procedure, I don't use NWDS.

Anyway, I checked JTECHS and it has the same level as the EP component.

The connection test with the SLD is successful.

I'm checking the SLD installation but, up to now, nothing wrong (or missing) has been noticed.

Regards,

Eric.

Hi Eric,

Check the SLD connection and then verify whether the Business System is properly defined in the SLD or not sometimes the missing parameters create this exception.
