[news.eclipse.tools.jdt] Re: eclipse 3.0 build I200311211210 ant compile

["Darin Swanson" <Darin_Swanson@xxxxxxxxxx>]

The JAVA_HOME message comes from the Apache Ant integration. It is not
correct for fixing the problem in Eclipse.
Basically you need to allow Ant to find a compiler.
One way is to ensure that a tools.jar is on your Ant runtime classpath
within Eclipse.
You can add it yourself (Window>Preferences>Ant>Runtime>Classpath) or you
can start Eclipse using the -vm argument to point to your favorite JDK
install and tools.jar will be added for your automatically.
