Moving to Java 1.5 doesn't necessarily mean to abandon support for
Java 1.4. I am currently working on a project for a company that still
uses Java 1.4 (and I think there are lots of them). We needed a
library to generate MS Project files, but the only one we could find
was from an Open Source project that migrated to Java 1.5 a few
releases ago. The code in this library makes use of generics and has a
dependency on JAXB 2. What we did was to use retrotranslator
(http://retrotranslator.sourceforge.net/) to translate the library as
well as its dependencies (including JAXB 2) back to Java 1.4. The tool
operates at bytecode level and supports all Java 5 constructs
(generics, enums, annotations, etc.). It also emulates the most
important parts of the Java API. We were able to use the library to
generate MS Project XML files on a Java 1.4 VM without any problems,
meaning that retrotranslator successfully backported the JAXB 2 RI to
Java 1.4! There is also a plugin (retrotranslator-maven-plugin) that
allows to generate Java 1.4 artifacts during Maven builds. Maybe this
could be an option for Axis2?
Sounds like a great idea to me, Andreas. If Retrotranslator can handle
JAXB 2 RI it should be able to deal with everything used by Axis2 and
related projects. The features which are not supported should be easily
avoidable.
