HTTP adapter - 500 Internal server error

Hi Experts,

I have configured a B2B scenarion in which i am using HTTP receiver adapter to send data to vendor.I have checked my configuration every thing is fine but i ended up with the error as below.

SXMB_MONI:

PLAINHTTP_ADAPTER">ATTRIBUTE_SERVER

HTTP server code 500 reason Internal Server Error explanation Internal Server Error

And the queue status is saying red in sxmb_moni also the error in SMQ2 is as follows

XI Error ATTRIBUTE_SERVER.PLAINHTTP_ADAPTER: Queue

I have implemented the notes 804124,807000 but no luck.Also i have restarted the J2EE server and done the soft shutdown but no use.

If i look into th queue scheduler in SMQR its in INACTIVE.

Any hint will be helpful.

Thank You
