Jco Destination (SLD)

Hi together,

I know, this question would asked often: I have problems to create a Jco-destination to a SAP System ECC 5.0.

My System-Landscape:

I have only one Netweaver 2004 with, Portal, SLD etc. for testing and one SAP ECC 5.0. We had any SLD in our landscape. So I setup the SLD in the netweaver described like in this thread content-administrator---create-jco-connection.

I have done all the steps which Sam Mathew described.

But when I test my Jco destination I got this error: "com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed".

My questions:

The only thing what I want to try is a Web Dynpro which use a RFC Connection. What is the minimum of configuraton to have this (I don't need a system landscape for transporting)?

When I define a Technical System type WEB AS ABAP I can set only a message server. It's not possible to define an application server.

But: It's also possible to define a Jco Connection in the SLD administration if I choose the WEB AS Java System (my netweaver portal). At this place it is possible to take the application server instead of message server. But when I going then to <myhost>/webdynpro I got errors in the page for the Jco Connections. Why?

If I try to transfer the informations of the ERP from ECC 5.0 to the SLD-BRIDGE via RZ70 I got errors (instead of using the zip file). First the RFC-Destination SAPSLDAPI doesn't exist and I created it. I create also the RFC service in the visual administrator. But the SLDCHECK wrote: "RFC ping returned exception with message: Error opening the RFC-Connection".

Can anybody gif to me some additional hints what to do, perhaps some tests which I can make on the J2EE engine?

The engines are in the same domain. BSPs from the ECC are working in the portal.

Regards Thomas

    Hi Thomas,

    Did you check out if your services and host files are correctly configurate? Furthermore did you check out ifyou can ping your servers from your WAS using name host ?

    Regards
