URLConnection problem further investigated

Question

Hi!
I have a problem (of course). I can create an URL connection, write data to it and receive the result (see "Check result" comment) using JRE 1.4.1 without any problems. But with JRE 1.3.1 I get a FileNotFound Exception when I do "InputStream is = urlConn.getInputStream();".
Am I doing something wrong?
Thanks in advance for any hints.

// Create CGI URL.
String strFile = m_strDataURL + objectID;
URL urlCodeBase = applet.getCodeBase();
URL urlWriteCgi = new URL( urlCodeBase.getProtocol(),
urlCodeBase.getHost(), strFile);
// Setup URL connection.
URLConnection urlConn = urlWriteCgi.openConnection();
urlConn.setDoOutput(true);
OutputStream os = urlConn.getOutputStream();
BufferedOutputStream bos = new BufferedOutputStream(os);
DataOutputStream dos = new DataOutputStream(bos);
// Post data.
cat.debug( "Writing object properties for " + objectID + "..." );
int iNofProperties = properties.size();
cat.debug( "Number of properties: " + iNofProperties );
String totalBytes = null;
for(int index=0; index < iNofProperties; index++){
cat.debug( properties.get(index).toString() + "=" + values.get(index).toString() );
dos.writeBytes(properties.get(index).toString());
dos.writeBytes("=");
dos.writeBytes(values.get(index).toString());
if(index+1 < iNofProperties){
dos.write('&');
dos.flush();
dos.close();
// Check result.
InputStream is = urlConn.getInputStream();
BufferedReader in = new BufferedReader( new InputStreamReader(is) );
String t = in.readLine();
while( t != null) {
t = in.readLine();
in.close();

In 1.3.1 and previous releases the HTTP protocol handler through a FNF exception for HTTP errors that it didn't handle. 1.4 has lots of fixes and improvements and also handles more HTTP errors automatically. If you really need to find out what 1.3.1 is doing then get a network trace and post the HTTP response from the server here.
