BPM Process is not started

Question

Hi All,
I defined an Integration Process which is triggered by an Asynchronous message
(Receive step with "start process" checked).
The trigerring message is sent through the HTTP Adapter
(See: http://help.sap.com/saphelp_nw04/helpdata/en/82/f4993c03e0cd37e10000000a11405a/content.htm)
and routed in the XI to the Integration Process I defined.
The java code I use to send this message is attached:
URL url = new URL("http://sapxi:8000/sap/xi/adapter_plain?" +
     "namespace=<my_namespace>&" +
        "interface=<my async interface>&" +     
        "service=<the portal business system>&" +
        "qos=EO");
URLConnection urlConn = url.openConnection();
urlConn.setDoInput (false);
urlConn.setDoOutput (true);
urlConn.setUseCaches (false);
urlConn.setRequestProperty("Content-Type", "text/xml");
DataOutputStream printout = new DataOutputStream(urlConn.getOutputStream());
String content = getXMLInput();
printout.writeBytes(content);
printout.flush();
printout.close();
Alas, According to SXMB_MONI_BPE, the integration process doesn't start.
Also, There is no record of the sent HTTP message in SXMB_MONI.
I used the same code with slight changes with a synchronous HTTP message
and a S/A-Bridge Process.
The changes were:
1. no "qos=EO", which is for asynchrounous message.
2. urlConn.setDoInput (true);
3. urlConn.getInputStream() to get the http response.
This way worked: S/A-Bridge Process was started, and I saw the message in SXMB_MONI.
I couldn't find why it doesn't work in the first scenario.
Any help will be appreciated.
Thanks ahead,
Yoav.

Hi Krishna,
I can't reward points right now (probably temporary unavailable).
I will reward 10 points as soon as it'll be possible.
When I tried it with the client you pointed out to it worked.
I noticed that this client prints a response also when the message is asynchtonous.
When I added a input read from my UrlConnection:
1. urlConn.setDoInput (true);
2. urlConn.getInputStream() to get the http response.
it worked perfectly.
I guess the HTTP Adapter sends an acknowledgement also for asynchronous messages,
and discards messages if their sender doesn't get this acknowledgement.
Many thanks,
Yoav.
