bluetooth connection problem

I am trying to connect to l2cap service on my computer via my mobile.
Thru J2ME I am able to search l2cap service and for that ServiceRecord
I call getUrl.
But when i connect using this url an exception occurs
bad psm.

For the given url psm was f , I am not sure if psm in url can be hex
otherwise what else it mean?

I have tried other psm but I get the same error.

I am try to connect to HID service for which psm should be 11?
