Referencing External .class Files In Classpath
Hi,
I'm trying to build an Ant project that uses some Apple Cocoa classes.
These are stored as .class files and not as jars. They reside in a
completely different folder to my project. I can compile and run my
program by referencing these from the command line as follows:
javac -classpath /System/Library/Java:. MyProgram.java
java -classpath /System/Library/Java:. MyProgram
Is there a way I can replicate this functionality using Ant and add the
directory (System/Library/Java) to the classpath?
I've tried solutions from the Ant documentation and the archives of
this list but haven't been able to get anything to work yet.
Thanks in advance,
Steve.

Thanks a lot :D That was exactly the problem and your solution
worked!!!
I used the copy task to copy the files. I've never worked with jars
before so just assumed by setting the classpath it would reference the
files. I didn't realise they had to be copied also.
Anyway its working now, and thanks again for your great help!

so the JVM can't locate them. You have to insert them in the jar file in
order to use them. Use something like the copy task to copy them in your
jar's document root or wherever you like them. Also you might want to start
the jar file from the command line in order to be sure that the problem is
in ANT. If theproblems continue, please let me know. Hope that helps.

The other method you suggested doesn't work either :-(
I hadn't thought about whether it breaks during compilation or
execution. It breaks during execution. It compiles OK and once the
program loads up and attempts to find the NSSpeechSynthesizer object it
breaks. I guess this means that its finding the path OK during
compilation and the problem is something else??

First of all I want to say that in my opinion your code looks fine. I am a
little bit astonished by the part:
<javac srcdir="${src}" destdir="${bin}" includeAntRuntime="no"
classpathref="lib.path" debug="${compile.debug}">
<compilerarg value="-classpath"/>
<compilerarg value="/System/Library/Java/"/>
</javac>
Maybe, I am not quite sure, so maybe there is a problem when using
classpathref and <compilerarg value="-classpath"/>. I don't know whether
some kind of confrontation could arise. Let me suggest you something. You
have a
<path id="lib.path">
<fileset refid="lib.jars"/>
</path>
defined. Why don't you just add your folder to this path and then call
classpathref="lib.path" in your javac task. Something like this should work:
<path id="lib.path">
<fileset refid="lib.jars"/>
<fileset dir="/System/Library/Java">
<include name="**/*.*"/>
</fileset>
</path>
Also tell me does your code now compile and breaks down during execution or
you can't compile it at all?

Thanks Petar. I tried running ant from the command line and replied to
this mail with the results shortly before you sent your reply. If you
haven't yet seen it, it was just to say that I got the same problem
doing it that way.
I think the jar is in the right place. Xcode allows you to modify the
path where it searches for the ant installation and this is currently
pointing to the correct place where I copied the file. Also, before I
was referring to it wrongly and the project wouldn't compile saying it
couldn't find compilerargs. When I fixed this it compiled OK. So I'm
pretty sure its finding the compilerarg task OK.
As for the error I get its this:
Exception in thread "main" java.lang.NoClassDefFoundError:
com/apple/cocoa/application/NSSpeechSynthesizer
at SpeechSynthesiser.<init>(SpeechSynthesiser.java:11)
at Game.<init>(Game.java:35)
The package its referring to is the Apple Cocoa speech synthesizer
package. This is found on Macs in the folder /System/Library/Java
which is the path I am pointing too. Like I said earlier if I use
javac from the command line and not ant it picks this up OK. So I'm
pretty certain the error is somewhere in my build.xml file. As it was
system generated (minus the few additions I've made to try and fix
this) I'm not sure if its 100% correct.

I am in a hurry right now so I will look further on your problem tommorow
morning. Meanwhile you may try to test your application via console instead
of in your IDE. If it works then you should add your jars in the classpath
of your project. Also the problem may have been caused by not inserting the
jars in the right place. Many IDEs have their own ANT_HOME. Elcipse's is in
plugins/ant-1.6/. Try to run ant from the command line, and also it would be
useful if you supply the stackTrace. We don't know which class isn't found.
Right?
Hope that helps...

Many thanks for all your help Petar. Sadly it still won't work. I
know for a fact my directory is correct because it works when I compile
and run the program from the command line. But from within my IDE
Xcode I still get the class not found error. I have copied my entire
build.xml file below. As you can see its laid out exactly as you
suggested. Unless there is some error in another part of the file
preventing this from working, I can only assume the problem lies with
the IDE, and if I can't find out the problem I will have to look for an
alternative.

Your vision is quite true . The / symbol represents the root folder in Unix,
so ant should find the folder you are passing as an argument.
Alternatively I could be defining the compilerarg statement wrongly.

this should be
<compilerarg value="-classpath /System/Library/Java/"/>
javac -classpath /System/Library/Java:. MyProgram.java

> Yes you are right that this fragment is wrong. First of all to ensure you
have your tasks in your classpath use:
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
<classpath>
<pathelement location="ANT_HOME/lib/ant-contrib.jar"/>
</classpath>
</taskdef>
as "net/sf/antcontrib/antcontrib.properties" describes every additional task
and it is placed in your ant-contrib.jar so you have to add it like a
classpath. Second your javac task should look something like this:
<javac srcdir="SRC" destdir="DEST">
<compilerarg value="-classpath"/>
<compilerarg value="DIRECTORY/"/>
</javac>
You can't just place <compilerarg value="-classpath DIRECTORY"/> because
there is a blank space between -classpath and DIRECTORY and it will get
quoted. So you put the two strings as separate arguments. I tested it on my
machine and it worked fine. Although I was a liitle bit confused because I
have never used compilerarg to pass a directory to the classpath. I most
oftently use a
<path id="compile.cp">
<pathelement location="DIRECTORY/"/>
</path>
---------------------
<javac srcdir="" destdir="" classpathref="compil.cp"/>
structure and it always wokes fine. Anyway I hope I helped.
P.S Dont forget to exclude any package directories and to place a / after
DIRECTORY.

You were right I hadn't copied the file to the $ANT_HOME/lib folder.
But after doing that it now runs, but still gives the class not found
error. There are 2 possible problems as I can see it. Either I'm
referring to the directory wrongly, or else I haven't defined the
compilerarg statement correctly.
When I refer to my directory which is /System/Library/Java this is the
reference from the root folder on my hard drive, and is the top root
folder of the package I want to use. Could it be that Ant is looking
for that folder from within the current folder my Ant project is stored
in and not the root folder of my computer? In which case how can I get
it to point to the computers root directory? I thought starting with /
would do that.
Alternatively I could be defining the compilerarg statement wrongly.
Firstly I have placed it within the <javac> tags. Is this the correct
location? Also, is the compilerarg statement below the correct way to
carry out the javac command line statement below it?
<compilerarg line="-classpath /System/Library/Java"/>
javac -classpath /System/Library/Java:. MyProgram.java
Thanks.

Thanks for your help so far but I still can't get it to work. Firstly
I tried the additions to javac that you outlined above but I still got
the class not found error. I then tried downloading the ant-contrib
task. I have referenced this as outlined in the documentation and
copied the jar file to my lib directory of my project. But I still get
the could not create task error. Below is the code I added to my
build.xml file. Is this correct?
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
<classpath>
<pathelement location="./lib/ant-contrib.jar" />
</classpath>
</taskdef>
<compilerarg line="-classpath /System/Library/Java"/>

I tried the compilerarg task but got the error "Could not create the
task or type of task: conpilerarg". I declared this as <compilerarg
line="-classpath /System/Library/Java/"/>.
I also tried the other methods you listed but I still got the class not
found error. My build.xml file was generated for my by my IDE Xcode
and currently looks like this. Sorry if I am missing something obvious
but I am totally new to Ant.

You can always use the <compilerarg> task to pass arguments to the compiler,
but rather why don't you try
<path id="compile.cp">
<fileset dir="YOUR DIR">
<include name=""/>
</fileset>
</path>
and later on call the classpath using <javac srcdir="" destdir=""
classpathref="compile.cp"/>
Or just use <classpath>
