Subject Re: Moving from Windows to Linux (Ubuntu)
Author Ian A. Newby
At the moment it is just test code, hardcoded in the java code.

Note that I can connect to the database using isql, remoteley from
another machine using ibexpert. The versions of Tomcat are basically
the same, 5.5, one is 5.5.10 and the other 5.5.17 I think.

Why would the network connection fail? I am also connecting to a
remote SQL server database using the jTDS driver and that works OK.

I've tried connecting to a remote firebird database and that fails too.
