First try at free-java-sdk with jcalendar... some help required.

Hello,

motivated by the discussions about free java on this list, I did my first try at freeing a Java package (without promise yet, hence no ITP). I chose jcalendar (http://www.toedter.com/en/jcalendar/) as I raised an RFP and it seems relatively simple, extracted it, installed free-java-sdk, put back the alternatives to Sun's Java (grrr! Shouldn't the package have less priority than java-package packages?).

Then in the jcalendar directory, I edited src/build.xml, replacing modern with jikes in the line: <property name="build.compiler" value="modern" />

Then the following:

any idea how to go further? The compilation with Sun's java 1.4.2 works without warnings or errors. Should I try to install SwingWT or something similar? I also don't understand why ant has a different behaviour with or without -debug, and why 'ant clean' still spits compilation errors?

I honestly say that I have only basic java knowledge, enough to more or less understand code when I read it, and be able to patch it, and package it (freemind), but that's about it.

Oha, almost forgot: I'm at testing/sarge level:
ii  classpath-tools 0.0.20020812-1 Free 'javah', 'javap', 'serialver'
ii  fastjar         1:3.4.3-12     Jar creation utility
ii  jikes-sablevm   1.11.3-1       Wrapper for jikes using classes fr
ii  sablevm         1.11.3-1       Free implementation of Java Virtua
ii  free-java-sdk   1.0-1          Complete Java SDK environment
ii  ant             1.6.2-2        Java based build tool like make

Thanks, Eric
