SOAP over HTTP

[charu latha]

I am trying to send an envelope over HTTP. I initally had an apache implementation that looked like :

    
SOAPHTTPConnection stc;
stc = new SOAPHTTPConnection();
msg.setSOAPTransport(stc);
msg.send(url, "", env);
SOAPTransport st =msg.getSOAPTransport();
BufferedReader br = st.receive ();
String line;
while ((line = br.readLine()) != null )
{
   buf.append(line);
 }
br.close();

The above code worked just fine.

I changed the above implementation to :

    
SOAPMappingRegistry smr = new SOAPMappingRegistry();
StringWriter sw = new StringWriter();
env.marshall(sw,smr);
PrintStream out = new PrintStream(urlConnection.getOutputStream());
out.print(env.toString());
DataInputStream inStream = new DataInputStream(urlConnection.getInputStream());
String inputLine;
while (null != (inputLine = inStream.readLine())) {
   System.out.println(inputLine);
}

And this one does not work. I am using the same request for both the implementations. The second implementation always gives me a 500 HTTP_INTERNAL_ERROR. Obviously something is wrong and i am unable to decipher what.

Can someone throw light please?

In cases like these -where code was changed, but the functionality has not- it is useful to look at the actual SOAP that gets sent over the wire, so you can compare whether they are identical. There's a tool called tcpmon which acts as a SOAP/HTTP proxy that can visualize requests and responses. It's part of Axis 1, but works independently of it.

Will try out the tcpmon. In the meantime i also noticed that i get an exception and that is Permission(java.net.SocketException <url with port number> connect, resolve).

Again i havent changed the URL or the ip for this request

Hi -

tcpmon is definitely an excellent suggestion - please consider it.

Also - is there any chance somebody might have changed a security policy (or similar system configuration) on your host?

Nope thats not changed. Anytime i want to run the apache implementation it executes just fine.

[charu latha]

I must be a real dumb person. I cant seem to get tcp mon working either. I am assuming that i have to enter in the admin tab :

local port : <some port number where the monitor can run>
server name : <name/ip of the host where the webservice runs>
server port : <port number which hosts the service>

Is the above assumption correct?

[Ulf Dittmer]

That is correct. After that all that remains to do is to point the WS client at localhost:localport, and you should start seeing requests/responses.
