The problem is that name of CJO is already exist in the SDL, that is correct beacuse this application is going to be used the same SLd in order to connect to the same SAP Systema QAS, Prod respectivelly.

How can i solve this problem, my intention is to have only 1 application Wd java with two deferents JCO destiny independent to avoid any change in the code afeact the deploy which is in productivo.

How can i managed this situation.

Thanks a lot for helping me.

Hello,

There is no such option to use two JCo for a single WD Application as per your requirement. You can try with below two things

1. Create another model with another JCo name. Which took more effort to change the source code wherever you used the Model.

2. In your Production system delete/deactivate the old JCo (if possible) then deploy your application. Then it will create the JCo same as before. And if other applications are also using the same JCo there should not be any problem once they are newly created.

Thanks

Shankha

Hi jtovar,

I would suggest you to maintain deployment server details same as your previous server and try deploying again.

This way you dont have to maintain two sets of JCO's for each server.

You can maintain these details in Windows - >Preferences - > SAP J2EE engine

Here give the port number and message server names of your previous server.

Production server NWDI details can be used in development server.

Hope this will resolve your issue.
