RNO Format Error: Content length is 15,307. Data length is 9

Hi,

I m implementing 3A4 (Seller side) pip.
Trying to post 3A4 RNO to our local host bu t getting below error:

RNO Format Error: Content length is 15,307. Data length is 960,639,537. [ESRN11.000020.000010]

Tried with changing byte/strem loadAs options but none of them are working.

Initially I had used sample 3A4 modeller, but closing comments of one of SR [ SR-1-69432681]says:

The issue was that cx was trying to use the RN Sample PIP3A4 and he did not install the Seller Model. After installing the Seller Model it started working fine.

Created a new model using standard 2 way pip process, still facing same issue.

Where can i get a Seller Model & how to install?

Is there any help available on setting up of 3A4 (Seller side) event on Wm 6.1?

I m new to Webmethods, doubtful over configuration, though it seems correct.

Any help will be appreciated.

thanx
