tau java build

[Pie Jang]

ant newbie...in TAU (http://www.cs.uoregon.edu/Research/tau/home.php) in order to execute an instrumented program you would set PATH to TAU bin and set LD_LIBRARY_PATH to TAU lib then just tau_java <a program> instead of java <a program>...how can i change an ant build to make this work, please? the error message for:
<!-- to run a single node --> <target name="run"> <tau_java fork="yes" classname="org.jppf.node.NodeLauncher" classpathref="run.classpath"> <!--<jvmarg value="-server"/>--> <jvmarg value="-Xmx16m"/> <jvmarg value="-Dlog4j.configuration=log4j-node.properties" /> <jvmarg value="-Djppf.config=jppf-node.properties" /> <jvmarg value="-Djava.util.logging.config.file=config/logging-node.properties" /> </tau_java> </target>

Problem: failed to create task or type tau_java
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

is this really declaring a custom task?

Hi Jang, welcome to JavaRanch!

First please add code tags for code samples. I've added them for you here (type=XML).

Normally there should be a <taskdef> tag associating the tau_java task with a Java class that implements it. They must document that somewhere in the site you linked.
