Snapshot releases for md4j (or anything for that matter) are not hosted 
by the main maven repo; only 0.2 is available there.

Please let us know if you find this usefull or have any issues; we are 
thinking of working on a new version with fixes and JBoss Seam support.

Hey Wayne,

You're fast :-)

Ah, guess i need to put that [1] in the POM (plus i need a parent POM as
an umbrella for md4j (the core) and quickstarter.

Weird. I'm using 1.5 right now but JAXP should have provided that in 1.4
AFAIK.

Good catch.

I think you will find those modules much easier to use, plus that is
where the fun of MD4J starts :-)

I agree with all that but face some issues:

* Domain tests would only make sense if generated as well IMHO.
* I have no experience in writing tests that depend on a container (with
or without mock objects) so this is rather hard for me when there is so
much to do :-/
* writing tests for the core is also hard as i cant figure out what i
want to test. Havent tried to test ant tasks before either.

BTW i dont want to ask too much, but it would be helpfull for the
(currently non-existent) other md4j users if we did this on md4j-user

That probably means the class has ben compiled for Java 5 (although
build.properties says 1.4?). What version of Maven are you using? Right
now the project has been ported to M2. I havent removed the old POM
(project.xml) yet, but the maven 1 build should be broken.

Have you tried the ready-to use jar from the SF project page? Try that
one; in the meantime i'll finish up with the maven 2 port and you'll be
able to build on java 1.4.

hth,

[Konstantinos P. <kpa...@ma...>]

in my pc the JAVA_HOME,classpath,path etc are set to j2sdk1.4.2 (jre 
1.4.2_10)
yesterday i updated the project and then i builded it using maven in 
order to get the md4j-0.1.jar
i used the jar (as you describe in ant-how-to file) to create the ant 
target in the build file and
then when i'm trying to run the target i'm getting the error:

*java.lang.UnsupportedClassVersionError:
