Possible Socket Handling Bug? : Applet Cannot Make HTTP POST Request to Tomcat w/IIS Redirector
Here's the Tomcat/redirector bug we're trying to track down:
Our applets/servlets run perfectly with Tomcat 4.1.18 and Apache 2.0.4X
(using jk as the go-between), but when used with the IIS redirector and
jk, the applets are unable to do any HTTP POST requests. Applets can,
however, successfully issue GET requests. There's nothing unusual about
the applet code, a snippet is shown below. The code blocks on the
oStrm.close() method. It works perfectly when using the Apache Http
server. Also provided is the stderr.log output. The stdout.log output
also contains some dump of what appears to be the HTTP content.
Unfortunately, we do have clients that will need the IIS/Tomcat combo.
This one is causing great hair loss, and any help welcomed. ;>
Applet code snippet:
====================
sURL = ...
sPostData = ...
URL url = new URL(sURL);
URLConnection urlconnection = url.openConnection();
urlconnection.setDoInput(true);
urlconnection.setDoOutput(true);
urlconnection.setUseCaches(false);
urlconnection.setRequestProperty("Content-Type","application/x-www-form-
urlencoded");
System.out.println("Getting Output Stream");
DataOutputStream oStrm = new
DataOutputStream(urlconnection.getOutputStream());
System.out.println("Got Output Stream");
oStrm.writeBytes(sPostData);
System.out.println("Wrote Stream");
oStrm.flush();
System.out.println("Flushed Output Stream");
oStrm.close();
System.out.println("Closed Output Stream");
DataInputStream iStrm = new DataInputStream(new
BufferedInputStream(urlconnection.getInputStream(), 8192));
int nSuccessCode = iStrm.readInt();
...

stderr.log output:
