Recall that a conformant rar file has all its classes in embedded jar
files, so putting the "outside" actual rar file on the classpath
doesn't give you access to any classes. If you put classes "loose"
inside a rar then a compliant j2ca container will probably ignore them.

Hi,
So the lovely JCA resource adapters (a.k.a. rar files)...
In Maven 2.0.9, these were added to the classpath
What exactly was added to the classpath?
In Maven 2.2.1, these are no longer added to the classpath...
The former made testing resource adapters easy, but causes issues when
packaging a resource adapter in an EAR...
The later simplifies packaging RAR files inside an EAR (unless
possibly you want to try for a skinny RAR) but makes testing the code
that depends on the RAR more complex.
For example, using the lovely openejb, I now have to do:
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<phase>generate-test-resources</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<includeTypes>rar</includeTypes>
<stripVersion>true</stripVersion>
<includeScope>test</includeScope>
<outputDirectory>${project.build.directory}/test-dependencies</
outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<additionalClasspathElements>
<additionalClasspathElement>${project.build.directory}/test-
dependencies/my-jca-impl.rar</additionalClasspathElement>
</additionalClasspathElements>
</configuration>
</plugin>
This looks to me as if its putting the rar on the classpath, not the
jars inside that contain the classes.
Which is just plain ugly...
My first thought was to have an
<additionalClasspathDependencies>
configuration in surefire... but I just know that it would be abused
like some mad crazy fool... and because it would not be taking part in
depMgmt, it would cause issues with releasing.... so that's not best
practice way at all then....
My second thought is to have
<additionalClasspathTypes>
<additionalClasspathType>
<type>rar</type>
<includeTransitive>true</includeTransitive>
</additionalClasspathType>
</additionalClasspathTypes>
So what do people think?
So are you proposing that if you have a rar, war, or ear, including it
as a dependency will figure out all the jars inside, compute the
actual internal classpath, and add all these to the maven classpath?
I have not problem with this but it's unclear to me if that's what you
are asking for.
thanks

P.S.
I've rejected my first plan... if Jason to aproves I'll resurect
it... otherwise Plan 2 or 3 (TBD)
