Hi,
At present I am evaluating Oracle 10g app server and I am in the process of
porting our current code from
Tomcat 4.1 to Oracle.
Our system uses to 2
servlets to produce a report. The first servlet sets up
headers etc and passes this onto the producer servlet that generates PDF
document(s). The first reads the result from the producer servlet through
an inputstream and sends the report to the client broswer.
The servlet opens a connection to the producer servet via the following
code :
URLConnection con = servlet.openConnection();
// Prepare for both input and output
con.setDoInput(true);
con.setDoOutput(true);
// Turn off caching
con.setUseCaches(false);
// Work around a Netscape bug
con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
// Send headers
sendHeaders(con);
// Write the arguments as post data
DataOutputStream out = new DataOutputStream( con.getOutputStream());
out.writeBytes(argString);
out.flush();
out.close();
return con.getInputStream();
//end method
The second servlet(producer) gets the data and tries to send back the pdf
doc.
However,before that can happen, an exception is thrown with the following stacktrace :
java.io.IOException: Server returned HTTP response code: 500 for URL:

I know there probably is a better way of communicating with servlets, but this is legacy code that I just want to port for the time being.
I am assuming I need to configure something on the App Server or the HTTP server ? As mentioned before code works fine with tomcat.
Any help on this matter would much appreciated.
Thanks in advance,
Shameer
