Could not create JCOClientConnection for logical System: MUSA_MODEL_DATA

[Former Member]

Hi,

I am facing a big problem...I have created WebDynpro Application & when I am running that application from WebDynpro, it's showing the page but giving me the error message as:-

Could not create JCOClientConnection for logical System: MUSA_MODEL_DATA - Model: class com.bcone.bcool.musa.model.MUSABAPI. Please assure that you have configured the RFC connections and/or logical system name properly for this model!

What do I do? what connections I have to check?

pls help.

Hi,

It seems you have not created JCO connections to access the backend R/3 system.

This document will guide you through the process,

Hope this helps !

Hey if you are connecting to SAP system making use of adaptive RFC model you hav to create logical systems(JCOs).So while creating the model you have to specify 2 logical system names(one for model data or on for the meta data).If you have not created the JCOs or if the JCOs are not active then you are going to get this type of error.To activate those JCOs ask your administrator to activate the JCO for metadata of your application.If you are having proper credentials then log on to portal

System administration>webdynpro>expand the local directory>select your project>click on maintain JCOs and activate the JCO for the metadata.

Or else change the logical system in your application.
