Thanks Mudasir.
That tool was actually new to me.
Its a helpful tool indeed. However as you mentioned that it gives Info about authentication failures along with user id, it still does not serve my purpose.
I think there is no tool or trace as of now in AS JAVA which can match the information that we get through ST01 in AS ABAP.
I have opened a support message with SAP regarding this. Lets see what they have to say.
