Environmnet: winXP,jboss-3.2.6,jboss-3.2.6RC2-nukes-2.0-DR,nukes-2.0-DR-src
I set the
JBOSS_HOME=${jboss-3.2.6}
NUKES_HOME=${nukes-2.0-DR-src}

I build the nukes following the instruction in http://www.jboss.org/wiki/Wiki.jsp?page=InstallUninstallUpgrade

when I execute the build.bat under the $NUKES_HOME/build
I failed,the fault message is as below:

BUILD FAILED

file:D:/Portal/JBoss/nukes-2.0-DR-src/portlet/build.xml:123: Could not create task or type of type: webdoclet.

Ant could not find the task or a class this task relies upon.

This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'webdoclet'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and optional.jar is absent
Fix: look for optional.jar in ANT_HOME/lib, download if needed
- The task was not built into optional.jar as dependent
libraries were not found at build time.
Fix: look in the JAR to verify, then rebuild with the needed
libraries, or download a release version from apache.org
- The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
and needs to be declared using .

Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath

Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.

i checked as the above said,but i still donot know where the problem is,
it said The task needs an external JAR file to execute,what the external JAR which here said is?
I need your help!
tks
