EP5: Access Data Source (System Conf) properties

Hi ,

I am using EP5.0.In my portal , I have a tab called "System Configuration" and in that I have a sub tab called "DataSources" . I am putting in details such as URL , Username argument (say UName ) (not the username itself) and the password argument (say Pwd) (not the password - the argument like PWD ). these arguments are like -

used in the URL to check like UName = '..' and Pwd ='...' and these arguments may be different for differnet datasources... I want to get these details in the iview program ...

like

for datasource

'sdn'--- username argument = UName

password argument = Pwd

'sap'--- username argument = UserName

--- password argument = Pass

I want these details in the program ......

I should be able to pass the data source name and then it should give me these details ...so that i can use these arguments in my user mapping for other users...

what api should i use? what should i use....

please reply as soon as possbile...
