Error in HTTP --> XI---> RFC & File Scenario

Hello ,

While working with the (http >BPM > RFC & FILE ) scenario ,

I am getting following error...

<b>And while using the http Client I posted the test xml ...But I am unable to see it in the SXI_MONITOR...</b>

And using RWB --> Componet Monitoring --> Integration Engine --> Test Message I triggered the Test XML

then its going to sxi_monitor but giving error...

<b>"The process does not support the given synchronous interface or does not support synchronous messages"</b>

what should I do....

Here I have considered in defining in DT for Http Considered it as Asynchronous...is it something wrong...if so what needs to be done.

Please help me in this regard...
