[Catalina] FYI: pending Tyrex changes

[Sam Ruby]

In catalina/build.xml there is the following:

   <available property="tyrex.present"
    classname="tyrex.jdbc.xa.EnabledDataSource" />

FYI - this matches the naming structure for the latest released version of
Tyrex (0.9.7.0), when build from cvs, the name of the jar produced is as
follows:

   tyrex/resource/jdbc/xa/EnabledDataSource.class
