Error creating JCA connection factory in NWA

Question

Hi,
I need to load an file with idoc content into a XML.
So parameter IDOCXmlToFlatConvertor is required  and it's necessary to create a JCA Connection Factory in NWA.
I'm trying to do it using :

http://help.sap.com/saphelp_nwpi711/helpdata/en/b5/bd93642dd3410f90ebea702399fac4/frameset.htm
But, when i try to create a JCA Connection Factory in NWA, systems returns next error:
com.sap.engine.services.connector.exceptions.BaseDeploymentException: Can not set authentication user store "null" in security context "MRD_300" for connector "MRD_300" in application "sap.com/tc~sapjra".
at com.sap.engine.services.connector.deploy.util.security.SecurityUtils.deploySecurity(SecurityUtils.java:507)
However, creating JCA connection as indicated in this blog, security tab doesn't allow any change  and field user store can't be modified.
How to do it?

Hello Carme,
From the error , I can see that the name of the JCA Connection Factory that you are trying to create in NWA is: "MRD_300".
This beautiful blog by William will surely help you rectify the problem.

Kindly check if you have done the following in your configuration:
1. Copy and create new dependent JCA Connection Factory from the JCA resource: "SAPJavaResourceAdapter15" 
2. You have to go to the "Configuration Properties" tab (and not Security tab) of your JCA connection Factory (MRD_300) to enter the credentials that will be used by this CF. Make sure that you enter the details properly. Eg. In your case, just check if the password is entered.
3. Also, check if the JCA resource "SAPJavaResourceAdapter15" is up and running (green traffic light). Else, restart the corresponding Java Service from NWA -> Operations Management -> Start & Stop -> Java Services
I hope this should solve your problem.
