Hre is what i have written in order to use a different compiler;

<target name="default" depends="prepare">
       <javac srcdir="${src-dir}"
           destdir="${build-dir}"
           classpath="${classpath}"
           deprecation="on"
           optimize="off"
           target="1.2"
           bootclasspath="${Java122Classes}"
           includes="${asi-compile-list}"
           excludes="**/lite*.java,**/Lite*.java" 
    />
  </target>

  <target name="asi-compile">
    <antcall target="default">
      <param name="build.compiler" value="${jdk122root}"/>
    </antcall>
  </target>

But it gives me the following error.
Buildfile: build.xml

asi-compile:

prepare:

default:

BUILD FAILED

yes i know that the the classic compiler is java1.2. But in order to use
different compilers based on what Nica said, i need to know whether the
compiler I am using is external or one of the javac-compilers ??

Thanks a lot

Ok here is the silliest question. How do I know what kind of compiler I am
using. ??

All of the targets in your build.xml will use the same compiler.

You can use different compilers if you do *not* define the property
"build.compiler" in your build.xml and call your compile-targets using
antcall specifying <param name="build.compiler" value="yourCompiler"/> on
each call. But this will only work with external compilers.

If you use one of the javac-compilers Ant will currently always use the
compiler that was shipped with the JDK you use to run Ant.
