Subject Re: [ib-support] InterClient, Tomcat Resource, JSP and charset
Author Rick Fincher
Hi Leos,

InterClient 2.01 doesn't support alternate character sets. You need to
download the type 4 JCA/XA driver from the Firebird project at There is a discussion group specifically for this driver

It works well, supports alternate characters, and has built-in connection
pooling. No one is supporting the open source version of InterClient
anymore so this is the way to go for the future.

It also directly connects to Firebird and Interbase without using IBServer.
