Hum, do you know what was being used for serving up the servlets? We used Tomcat here and did not experience those issues. I believe it was 4.0 although that version does seem to have a memory leak (at least on Unix).

I was just the DBA, not the JAVA developer, but --

We had a Database server using JDBC to talk to an application server. The application was written in Java and used Java thin client to talk to the client (endusers). The endusers had "any" Java compliant browser. No applets (security issues -- I don't remember what), only servlets on the application server.

It worked great for the developers (2). As soon as the customer accepted the application we let the head developer go (since the customer didn't want to pay for his time anymore). After about the third or fourth customer employee started up a browser session to the application server the browsers started timing out. Tracked it all down and the Java thin client was loosing track of which message went to which workstation.

We never had that issue where I am at. Can you explain it a bit more. What do you mean the client was unable to handle more then two or three connections? Do you mean that you where connecting multiple times from the same java application to the same database?

Last Java project that I worked on (about 1 year ago), the Java thin client was not robust enough to handle more than two or three connections simultaneously. More than that and the threads got "twisted". Client application would hang waiting for a response from the database. The database had sent the response long ago but it never got to the client.

Hopefully this has been fixed in later versions of Java.
