Good Afternoon

please download antlr3-task.zip source from http://www.antlr.org/share/1169=
924912745/antlr3-task.zip=20
unzip/uncompress to temp folder
in org.apache.tools.ant.antlr.ANTLR3.java
change

.antlr.Tool class */
        commandline.setClassname("antlr.Tool")=3B
        fileUtils =3D FileUtils.getFileUtils()=3B

recompile

place org.apache.tools.ant.antlr.ANTLR3 in classpath

ant -debug SimpleC=20

will explain the workings

Juergen can you correct the codebase for antlr.Tool to refactor to org.antl=
r.Tool so org.apache.tools.ant.antlr.ANTLR3 test harness runs correctly w/o=
 modification from above?

=20

Vielen Danke=2C
