JTC stands for Jakarta Tomcat Connectors.
There are two different types of connectors. Connectors that allow browsers to
connect directly to the Tomcat and connectors that do it through a Web Server.
The connectors allowing direct connections are distributed as jar files with
the Tomcat binary releases.
The connectors used with a Web Server are made of 2 components. One written
in Java and the other written in C. The Java part is included, as a jar file
,
with the Tomcat binary releases. The C part is released separately and may be
obtained from the
Tomcat Connectors Downloads.
The total number of different operating systems and web servers is sufficiently
large that it is not practical to provide binaries downloads for every
combination. Binaries are provided for most of the popular combinations and if
the one you need is not avaialble do not hesitate to ask for it on the
tomcat-user mailing list but please be patient and accept you may have to build
it yourself with the help of the mialing list.
The CVS repository for JTC is called jakarta-tomcat-connectors and source
bundles (that include both the Java and the C components) are available from
Tomcat Connectors Downloads.
