I developed a client/server application running on WinNt 4 Service Pack 5. The communication is done with Sockets. The server creates one Thread for each request and uses jdbc odbc-bridge in order to access MS-Access 97. At first I used jdk1.2.2 but after I had some strange ODBC errors (method sequence error) I installed jdk1.3. However I'm not able to get rid of undetermined "java.exe application error, cannot read from memory". Is anyone out there who has solved to have a multithreaded server application that uses jdbc without having application errors?
