David ,
which version of Linux are you using?
is it a Suse version?
did you try do a clean install of java (the basic jdk, not the server
version)?
i'm asking such things because i saw some strange problems with a suse
(i think it was a suse ans a Java server version)...
i think that it cannot come from the tool (ant)
it may come from the os and the java version....
if you can, try to install a RedHat or an Ubuntu, compile a jdk 6 and
tell us if it is working...
supareno
Hey Derek,
I tried to do what you did, but I still get the error.. I added the ACL to
my code and tools/jar to my PATH... but still doesn't work. Here is a piece
of my code.. I just wonder.. what else do you do with the ACL???
Project p = new Project();
boolean t = true;
Path path = null;
AntClassLoader ACL = new AntClassLoader(p, path, t);
p.setUserProperty("ant.file", buildFile.getAbsolutePath());
DefaultLogger consoleLogger = new DefaultLogger();
consoleLogger.setErrorPrintStream(System.err);
consoleLogger.setOutputPrintStream(System.out);
consoleLogger.setMessageOutputLevel(Project.MSG_INFO);
p.addBuildListener(consoleLogger);
try {
p.fireBuildStarted();
p.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
p.addReference("ant.projectHelper", helper);
helper.parse(p, buildFile);
p.executeTarget(p.getDefaultTarget());
p.fireBuildFinished(null);
db.insertBuildData(Integer.toString(revisionNumber), "YES",
"");
} catch (BuildException e) {
if (e.toString().contains("Unable to find a javac
compiler;")){
db.insertBuildData(Integer.toString(revisionNumber),
"YES", "Unable to find a javac compiler");
} else{
db.insertBuildData(Integer.toString(revisionNumber),
"NO", e.toString());
}
}

Here is how I have set this up to work:

AntClassLoader ACL = new AntClassLoader(Antproject, path, t);
//this causes ant to use the system path classpath since I passed in a
"true" value. To append //items, use something besides path = null.
Antproject.setUserProperty("ant.file", someFile.getAbsolutePath());
Antproject.fireBuildStarted();
Antproject.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
Helper.parse(antproject, someFile);
Antproject.executeTarget("package");
Antproject.fireBuildFinished(null);
This is not the complete source, but I did have to add some methods,
etc. You will probably want to add some stuff to the classpath to
include all the jar files in ant/lib directory. I also added the
java_home/lib/tools.jar to the classpath on my system.
I am going to start a blog with some of this info, because I also had a
heck of a time capturing the javac tasks output when adding a logger to
the build, as well as some other issues.
I was running this java program using a <java> task in a separate ant
file, btw. I also intend to fire a version from a perl script.

Hi David,
I never meant that you should modify the ant code.
Try launching your app with the fully qualified
path to the jdk java eg:
> /path/to/jdk/bin/java MyTestApp
So in other words don't rely on your PATH environment variable. It
could be
also that the bootclasspath has been overridden so that tools.jar has
been
taken out. Are you on the mac, in which case you don't have tools.jar?
Try the same experiment by stealing the very last line in the ant
launcher
script and hardcoding the values that you know you need to use. On my
installation of ant I would start with this line:
ant_exec_command="exec \"$JAVACMD\" $ANT_OPTS -classpath
\"$LOCALCLASSPATH\" -Dant.home=\"$ANT_HOME\" -Dant.library.dir=
\"$ANT_LIB\" $ant_sys_opts org.apache.tools.ant.launch.Launcher
$ANT_ARGS -cp \"$CLASSPATH\" $ant_exec_args"
I say this again, the idea behind this is that you need to assume that
your
environment variables and shell scripts can't be trusted and therefore
bipass them.
I mentioned this before, but remove any compiler fork option so that
the task
is being executed in the same vm. Then if it behaves differently in a
forked
vm, you know that the vm environment isn't being inherited properly and
that's where you need to look.
You could try removing all java installations from your machine and then
reinstalling just the jdk that you need. I know for example that windows
gets up to tricks such as adding a java.exe in the windows system
directory
that is always first in the PATH that you have to remember to manually
delete.
Sorry you are having all these frustrating problems, good luck.

Just a remark, when I run the application and /opt/jdk1.6.0_06/lib/
tools.jar
to the classpath. It gives me a different error message: "Compile
failed;
see the compiler error output for details." there is no error msg
and it
still says BUILD SUCCESSFUL

Hello Michael,
here is my code on how I'm invoking Ant:

consoleLogger.setOutputPrintStream(System.out);

Michael, I read somewhere that when you invoke ANT in java, it runs
in the
same JVM, and forking the ANT process might solve it. Do you have
any idea
how would I code this?? Make Ant ran in another JVM?

so just running JAVA worked as well as running /opt/jdk1.6.0_06/

So tools.jar is found alright. It's an environmental problem,
either in
the ant shell script (has that been tampered with?) or, more
likely, the
shell script you're using to launch it.
