It's a bit unclear if you are still unable to compile or you are just
commenting on the build process. If you are still having problems a few
things to consider:
- Make sure the ant.properties file is actually in your user.home
directory. For me in a windows environment this is (as default)
c:\documents and settings\<username>
- I believe both JDK 1.4.X and JDK 1.3.X are required for successful
compilation.
- One of my favorite ways of checking to make sure all of the variables
are being used by ant is adding the following lines to the showenv
target of the main build.xml:
<echo message="Additional Check"/>
<echo message=" j14lib=${j14lib} "/>
<echo message=" j13lib=${j13lib}"/>
<echo message=" JAVA_HOME=${JAVA_HOME}"/>
From command line you can then run "ant showenv" and be able to tell at
a glance whether the libraries are on your path.
Hope something here helps.

Hi,
With ant for Java, projects should successfully compile using:
tar zxf tarball-src.tar.gz
cd src
ant
I have both J2SDK 1.4.2 and Apache Ant 1.6.5. Yet the instructions for
compiling Derby required such things as:
adding a properties file to my home directory
configuring the properties file
installing javacc
Even after following the BUILD.txt instructions, the compile failed:
compile_reference:
[javac] Compiling 9 source files to derby/10.0/classes
[javac] Fatal Error: Unable to find package java.lang in classpath
or bootclasspath
From a purely technical level, since JavaCC has a BSD license, it can
be included in the distribution. Also, a basic installation can
presume default paths (use relative names, if at all possible), and
should be able to use the environment variables already set (e.g.,
$ANT_HOME, $JAVA_HOME), without additional properties.
HSQLDB provides an excellent example of the minimal three-step
compile, and also uses whatever version of Java is installed (e.g.,
1.5 or 1.4). (Okay, it's actually four-step, but the ant command
prints out help saying how to really compile everything; slightly
suboptimal, but at least clear.)
Simple is good. =) Good luck with Derby!
Sincerely,
Dave Jarvis
