Hi Shweta,
Use a list input type parameter in your Transaction. pass the input from the web page like
/XMII/Runner?Transaction=Default/abcd&listInput=[a,b,c].
[a,b,c] is how you pass the list.
You could use a loop to read the values or you could just use Transaction.listInput{index} to get the value in your transaction. Here listInput is the name of my transaction input parameter of type list.
