???HTTPS from Java Stored Procedure in Oracle???

Hi,

I have questions regarding making https connections from a Java stored procedure in Oracle. Below are the details of the scenario, followed by the questions:

The software:

Oracle 8.1.7
Aurora JVM 1.2.1

The Objective:

To develop a Java stored procedure in Oracle, wrapped in an Oracle Stored Procedure, that can make an HTTPS connection to a remote host. The java stored procedure will call a PERL script on that remote host via an HTTPS URL address, listen to a reply, and parse the response data.

The problem:

The stored procedure seems capable of making the https connection, but when it attempts to read data from the incoming data stream Oracle returns the error:

ORA-03113: end-of-file on communication channel

Then, if I try to run the program again, I get the following:

ORA-03114: not connected to ORACLE

The Java code being used is as follows:

create or replace and compile java source named "ModemQuery" as
import java.io.*;
import java.lang.*;
import java.util.*;
import java.net.*;
import oracle.sql.*;

public class ModemQuery {
private static URL url = null;
private static HttpURLConnection connection = null;
private static OutputStream response = null;
private static OutputStream out = null;
private static InputStreamReader in = null;
private static StringBuffer returnData = new StringBuffer();

private static String data;

public static String doPost(String mac) {

data = "stuff";

openConnection();
getResponse();

return returnData.toString();
}

// This method opens an https connection

private static void openConnection() {
System.setProperty("java.protocol.handler.pkgs", "HTTPClient");

returnData.append("In oC method: ");

try {
url = new URL("https://some.ip.address:443/perl_program.pl?var=" + data );

connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setUseCaches(false);
}
catch(Exception e)
{
returnData.append("oC Exception: " + e.toString());
}
}

// This method reads the incoming data

private static void getResponse() {

returnData.append("In gR method: ");

try {
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
returnData = new StringBuffer();

String line;

while((line = reader.readLine()) != null) {
returnData.append(line+"\n");
}

reader.close();
reader = null;
}
catch(Exception e)
{
returnData.append("gR Exception: " + e.toString());
}
}
}
/

show errors


The code gets as far as openConnection without generating any exceptions, but when it gets to getResponse() Oracle generates error 03113

Questions:

What about this code could be causing me to lose my connection to Oracle?

I believe I have the permissions set correctly, but is there some other configuration on the database side that needs to be done before I can run this program?

If anyone has ever tried something similar to this, could you please let me know?

Thanks for your help.
