change crystal reports password using java SDK

Hi Friends,

   I am new to SAP Crystal reports. is it possible to do following things using java SDK?

1. SDK code that can change the password (stored in CMC) for the Crystal Report...
2. Build a CR with embedded password
3. A webpage, that displays the CR (object) properties.. where password can be reset for the CR
4. Manually change the password in the DSNs
5. Run CR, the report should now run with the new password.

if so, give me some suggestions or sample code snippets Regarding this. Thanks for your help

Thanks
