RE: Sending post request in java

Well although I have never tested my client for SMS but for Push Proxy, one difference that I see with my code (using Sockets but the principle is the same) is the "Content-Type" parameter.

Try setting it to "application/xml" instead of "text/xml"

One more problem that I had is that all new lines have to end with \r\n and not just \n or \r

If all else fails you will need to use Ethereal (it is open source and you can get it from http://www.ethereal.com/) to make sure that the Content-Length of your post request is absolutely correct. Kannel is very sensitive to wrong content lengths.

Here is some code that succesfully sends a POST request to kannel WAP Push. I think that if you change the code to your needs you should make it work for SMS as well (sorry is in sockets not HttpClient - can't seem to find any old code with HttpClient :(

I used the HttpCLient, and i couldn't resolve the problem

here is a piece of code:

case Request.POST:

     methodP = new PostMethod(url);
     methodP.setRequestHeader("Content-type", "text/xml");
     methodP.setRequestBody(request.getRequest());
      client.executeMethod(methodP);
     response = methodP.getResponseBodyAsString();
     break;

do i have to set some attribute on the PostMethod???? is there any tip?

Thanks ..

I had the same problems trying to send Push Mesages from Java using the HttpUrlConnection.

Checking with Ethereal I found out that the HttpUrlConnection object breaks the request into two packets and that probably confuses Kannel.

I tried using sockets (more work of course) and everything worked well.

Also the HttpClient library from Apache Commons works well with kannel and is much easier to use than HttpUrlConnection.

Just don't use the HttpUrlConnection object.

Good luck!

Hi.

I'm triying to send to consecutive messages from kannel using the Java HttpUrlConnection, but after I send the first, the smsbox dies (but the bearebox keeps up).

My conf file is

group = smsc
smsc = at
modemtype = wavecom
device = /dev/ttyS1
pin = 1286
sim-buffering = true
speed = 115200
my-number = +58412*******

group = smsbox
bearerbox-host = localhost
sendsms-port = 13013
log-file = "/var/log/kannel/smsbox.log"
log-level = 0
access-log = "/var/log/kannel/access.log"
immediate-sendsms-reply = true

group = modems
id = wavecom
name = Wavecom
detect-string = "WAVECOM MODEM"
#broken = true
message-storage = SM
enable-mms = true
init-string = "AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0"
need-sleep = true

And my log is
