Web Dynpro connecting to ABAP trough RFC


I created WebDynpro application using ABAP functions accordingly to relevant tutorial. But i have problems with the last step - which is "Creating the JCO Connections."

I can create and test the connection called "WD_MODELDATA...." but i have problems with "WD_RFC_METADATA....". I truthly say that i cannot locate the source of the problem.

If i create WD_RFC... as (Application Data -> Single server) it creates and the test results OK, but later on when running the application i get an exception saying that i have not defined the connection as an MsgServerConnection in CIM. When i try to create is as Dictionary Meta ... i get errors while creating it.

!There is an interesting symptome on step 4.2 in "Create

!new JCO destination" wizard - when I select a Message

!Server the "System name" and "Logon Group" fields remain

!empty and disabled - isn't it strange ?

And in the end, after i press finish i get a red exclamation icon and a following message :

"Failed to create new JCO client connection WD_RFC_METADATA_DEST: com....WDSystemLandscapeException: Error while obtaining JCO connection: com....WDRuntimeException: Failed to resolve connection parameter for WD_RFC_METADATA_DEST at com...JCOClientConnection.resolveCOnnectionParameter4MsgServerJCODestination("

Everything in SLD is configured corectly (at least it seems so).

May the version difference (SLD 6.20 and WAS 6.40) be a problem?

I have WAS SneakPreview patch level 4, my OS is WINXP,SP1.

R/3 server i try to connect to is version 4.6C

    I had the same error with the Sneak preview. I followed all the steps mentioned in the used the SAP NetWeaver '04 Post-Installation Guide to set up SLD on the Sneak preview WebAS installation. You can find this at system landscape directory on sap web as java 6.40.pdf

    or try this shorter url -->
