Credential mapper not working

Question

"Please tell where I am wrong in configuring and calling credential mapper?????
I wanted to achieve single sign on using Credential mapping feature of weblogic server.It means using weblogic inner capability.
I thought of getting connected to pointbase server which can act as Enterprise Information System.
I did following steps to achieve single sign on using Weblogic Server Credential mapping feature.
Confuration Phase:
Step 1) I configured Examples as username and Examples as password in pointbase server which will act as my Enterprise information system.
Step 2) I wrote one connector class for connecting to pointbase server.
Step 3) I deploy that connector class.
Step 4) I configured Admin as username and Admin as password in my configured security realm which will act as Weblogic User.
Step 5) I did credential mapping in the connector class for mapping my Weblogic (Admin)
     user to EIS(Examples) user.
Calling Phase:
Step 1) I deploy one application to call pointbase server using the connector class.
Step 2) I try to get the connection to pointbase server using the follwing code
     getConnection("Admin","Admin");
     Where Admin username is my weblogic user mapped to Examples user of point base server whose mapping is already done in the connector class.
     I hope it to work for getting the connection.
