Could not create JCOClientConnection for logical System:

Hi,

I am facing a wierd problem in using the JCO destinations.

I created a page where it is using some JCO destinations say SAP_R3_HumanResources.

when i open the page it is working for the first time .without closing the page if i open the same page again it is giving the following error

Error connecting using JCO.Client: null

Error connecting using JCO.Client: null

Pernr:Could not create JCOClientConnection for logical System: SAP_R3_HumanResources - Model: class com.swissre.CustomData. Please assure that you have configured the RFC connections and/or logical system name properly for this model!

Please let me know how to solve this issue

Thanks

Hi Bala,

It seems that this is a custom webdynpro application which when executed causes such problem. This might be due to JCO connection not released back to the pool.

Please refer to the following threads and that might be helpful.

You might have to call disconnectIfAlive method on your model.
