RE: Modern compiler not found - looking for classic compiler errorwhen using ant on the as/400

["Gary L Peskin" <garyp@xxxxxxxxxxxx>]

Regarding the Ant issue:

Ant issues the first message when it can't load com.sun.tools.javac.Main
(the modern compiler).  This class is located in
/QIBM/ProdData/Java400/jdk13/lib/tools.jar which is apparently not in your
CLASSPATH or BOOTCLASSPATH while you're running Ant.  If you add it into
your CLASSPATH, Ant should work okay.

The second message comes because Ant tries to fallback to the classic
compiler.  To verify its availability, Ant tries to load
sun.tools.javac.Main.  Unfortunately, this is also in tools.jar so you have
the same problem as above.

How are you starting Ant?  Are you using
org.apache.tools.ant.launch.Launcher?  This is what is invoked on your PC
via ant.bat and it is this class that automatically adds tools.jar into your
classpath.  If you're starting Ant some other way, such as 

  java -Dant.home=c:\ant org.apache.tools.ant.Main [options] [target]

then, you're not invoking the launcher and need to have tools.jar in your
CLASSPATH manually.

Please try this and let us know.

HTH,
Gary
