One way to do it is to <unjar>[1] all other jars and
to <jar>[2] them again with your application:
<unjar src="lib1.jar" dest="${lib1.classes}"/>
<unjar src="lib2.jar" dest="${lib2.classes}"/>
...
<!-- After they are all unjarred, jar them here again
with your own classes-->
<jar destfile="yourApp.jar">
<fileset dir="${lib1.classes}"/>
<fileset dir="${lib2.classes}"/>
...
<fileset dir="your_compiled_classes">
</jar>
I myself think that it is a tedious way to include the
classes of all the libs you use in the jar of your
application. Instead I would prefer using manifest
attribute of <jar> task:
<jar destfile="yourApp.jar">
<fileset dir="your_compiled_classes">
<manifest>
<attribute name="Main-Class"
value="yourApp.yourMainClass"/>
<attribute name="Class-Path" value="lib1.jar
lib2.jar ..."/>
</manifest>
</jar>

JSmooth builds exe files from jar files. I read some
positive comments about it, but I never used, so use
it on your responsibility.
As for building native executables on Linux, I use GNU
Compiler for Java[4]. It can build native executables
(actually both for Linux and Windows) if it is passed
the relevant options.
