A few days ago I sent a message describing a problem I had compiling some
classes that use XML under Ant 1.3. I received a response suggesting I try
using includeAntRuntime = "no" in my <javac> task.
This solved my compile problems, but I'm having trouble running my custom
tasks that use XML. I define a classpath that sticks the xerces.jar at the
front of my classpath. My javac task uses it.
<path id="project.class.path">
<pathelement location="${basedir}/build/xerces.jar"/>
<pathelement location="${basedir}/build/jar_update.jar"/>
<pathelement path="${java.class.path}"/>
</path>
I have a custom task that also uses xerces.jar. I defined a taskdef for this
that uses the classpath.
<taskdef
name="buildupdate"
classname="com.lml.leaselink.update.BuildUpdateTask">
<classpath refid="project.class.path"/>
</taskdef>
When I attempt to run a task that uses this task:
<target name="move_files_for_update" depends="update_clean">
<buildupdate
makelogifnoupdates = "false"
buildloglocation = "${basedir}/${buildLog}"
lastbuilddirectory = "${basedir}/${lastBuildClassDir}"
newbuilddirectory = "${basedir}/${classDir}"
updatejardirectory = "${basedir}/${updateClassDir}"
removejardirectory = "${basedir}/${removeClassDir}"
/>
</target>
I get an exception for each of the XML classes that the task attempts to
load:
java.io.IOException: java.lang.LinkageError: Class org/w3c/dom/Document
violates loader constraints
...
java.io.IOException: java.lang.LinkageError: Class org/w3c/dom/Element
violates loader constraints
...
java.io.IOException: java.lang.LinkageError: Class org/w3c/dom/NodeList
violates loader constraints
...
Can anyone offer any ideas on how to fix this?
Thanks,
Steve C.
