Hi Jeremy,
JDK 1.4 includes an XML parser (some version of Xerces, I think) and
JAXP APIs in the runtime libs.
I just ran my JUnit tests with JDK 1.3.1_05, Ant 1.5.1 and XML format
output, and formatted the results with Xalan and <junitreport>. No
problems. Here are my relevant settings:
<junit printsummary="yes" dir="${basedir}/lib" fork="yes">
<jvmarg value="-Dtest.data.dir=${test.data.dir}"/>
<formatter type="xml" extension=".xml"/>
[etc.]
And for junitreport I just have:
<junitreport todir="${junit.reports}">
<fileset dir="${junit.reports}">
<include name="TEST-*.xml"/>
</fileset>
<report format="frames" todir="${junit.reports}/html"/>
</junitreport>
In ANT_HOME/lib as far as XML-related libs go, I have:
crimson.jar
jaxp.jar
xalan.jar
xercesImpl.jar
xml-apis.jar
No CLASSPATH settings, nothing in my JAVA_HOME/jre/lib/ext and no
special JVM args or jaxp.properties.
Why do I have two parsers and two sets of jaxp/XML API interfaces in
ANT_HOME/lib? Really because some tasks/tools require different parsers
and these seem to all play together fine without any conflicts.
FWIW, I was able to reproduce DocumentBuilder-related exceptions if I
put an older version of xerces.jar (downloaded directly from the Xerces
project) in ANT_HOME/lib, instead of the xercesImpl.jar that comes with
Ant 1.5.1.
