Problem with Connection Visual Composer 7.1 EH1 and R/3

Hi,

I´m with a problem on Visual Composer 7.1 (EH1) connection with R/3. When I Test a RFC (Test Data Service), the test occours with success (all data are returned). But when i run the application and call this RFC, a error happens:

Error in getting the connection Could not get connection for alias XXX. Contact your system administrator. 
 
Error occurred while executing the service: Could not get connection to the backend XXX

I configured this connection using this blog:

/people/nikhil.pai/blog/2008/02/20/connecting-to-backend-system ce-71 part-i

When i test the connection on NWA, the test occours with success too.

What can be happen?

Thanks,

Bruno
