I am running a networked J2ME application. Things work great for a while then, at random times, I get a IOException "malformed response message" when I try to process an ouput stream. could any one tell me some of the reason why I could be getting this message ?
Links to more information are also welcomed.
Thanks in advance.
Here's the stack trace on the IOException:
java.io.IOException: malformed response message
at com.sun.midp.io.j2me.http.Protocol.readResponseMessage(+138)
at com.sun.midp.io.j2me.http.Protocol.connect(+603)
at com.sun.midp.io.j2me.http.Protocol$PrivateOutputStream.flush(+17)
at java.io.DataOutputStream.flush(+7)
For me, this is only happening in a polling thread that's issuing a POST every handful of seconds. While this thread is running, another thread can issue a second POST request.
Do you have one and only one thread? Perhaps Sun has a multi-threading bug in http.Protocol?
I submitted this to the Bug Parade, but they want more information.
Specifically,
1- Do you have more than one thread issuing HTTP requests?
2- Do you close the HttpConnection between requests or reuse it?
3- Are you performing GET or POST queries?
4- If POST, how much data are you sending?
5- What type of content are you receiving in the reply?
6- How big is the reponse data?
7- Are there any non-standard headers in the query or response?
8- Are you sending the request to Tomcat or another HTTP server?
