Also, I dont see this message via SXMB_MONI. Is there any other way i can debug this error? What element am i missing in the input which is causing the NullPointerException in the SOAPAdapterBean? Can i get the SOAPAdapterBean.java file from anywhere and then may be i can debug it myself.
Thanks for your time,
