Subject [PATCH] add JAXP jars to classpath if possible
Date Fri, 20 Jul 2001 17:04:32 GMT
I just did a clean install of Ant.  I like the concept of having an
executable "ant" installed in $ANT_HOME/bin.  However, it does not
work right out of the box.  It depends on the user having JAXP JARs in
their classpath.  I am a strong believer in not forcing the user to
set their classpath any more than absolutely necessary -- it violates
the "no globals" philosophy of Java.  (I've been burned by conflicting
versions of XML parser libraries many times.  And using jre/lib/ext to
install extensions simply does not work, for some bizarre reason, for
many JARs.)

I'd like to propose that the "ant" script look for an environment
variable called "JAXP_HOME" and, if it's defined, add its "jaxp.jar"
and "crimson.jar" to LOCALCLASSPATH.

Here's a patch.

I'm not sure if I have committer access to jakarta-ant, but I'd be
happy to try if I get a thumbs up from this list.
