This is a minor problem while building on Mac OS X 10.4 The build.xml file java/build/org/apache/derbyBuild refers to tools.jar. There is no tools.jar in the Java Distribution on Mac OS X (atleast on Tiger). The classes that you're looking for (Taglet etc) are to be found in classes.jar. This causes the build to fail with ClassNotFound exceptions.
The fix should be to add yet another ant property which can point to the correct jar file depending on the os. Thanks, Manish
