[news.eclipse.tools] Re: Ant unable to find javac compiler

["Darin Swanson" <Darin_Swanson@xxxxxxxxxx>]

Eclipse will add the required tools.jar to the Ant runtime classpath iff you
start Eclipse with a JDK install.
Likely you have started Eclipse with a JRE install.
You can add the tools.jar to the Ant runtime classpath yourself or start
Eclipse and use the "-vm" option to point to your JDK install.
