Hi everyone,
I wrongly directed Jeremy into the direction of a possible
classloader problem. It is a regression bug in RIFE when it's run
without a initialized repository. I fixed this in RIFE, so don't
spend any time looking at what happens in Maven with regards to this.
Sorry for the confusion.
Jeremy, please use the latest snapshot of RIFE which should fix this:
http://rifers.org/downloads/rife/snapshots/rife-1.6-snapshot-20061220/
Best regards,
Geert

Hi All,
I have taken the liberty to create a sample RIFE application to
reproduce this behavior so we can work together to fix this. This
sample RIFE application is attached and is a Maven project. It has
a README file to explain how to prepare the environment and how to
reproduce is. Please use the attached so I can figure out if I'm
doing something wrong and if there is a workaround/fix available.
I'm sure I am not the only person to run into a problem like this.
Take care,
Jeremy

I am developing a RIFE web application that I am trying to unit
test. When my surefire tests run, RIFE is unable to load Java
classes properly. Here is the related portion of the pom.xml:

Before I explain the problem, here is a part of the stacktrace:

So...a little information about the structure. When my Maven
application runs the tests, the target directory looks like this:
target
/classes
/test-classes
/sites
/rep
/templates
RIFE can successfully load the sites/main.xml but RIFE then starts
to instantiate the SACHome object. This object is compiled to
target/classes but RIFE cannot find it. RIFE developers tell me
that RIFE's ClassLoader is being circumvented or is using the same
classpath as what the surefire tests are. How can I get my tests,
which include RIFE's engine, to have the same classpath? I've done
everything I can think of. Just to show you all the surefire
classpath:
[DEBUG] Test Classpath :
[DEBUG] /Users/jwhitlock/work/sac/src/web-app/target/test-classes
[DEBUG] /Users/jwhitlock/work/sac/src/web-app/target/classes
[DEBUG] /Users/jwhitlock/work/sac/src/web-app/target/classes

[DEBUG] Adding to surefire test classpath: /usr/local/maven-2.0/
core/plexus- utils-1.1.jar
As you can see, target/classes and target/test-classes are both on
the classpath and should allow RIFE to be able to load classes from
target/classes but is not able to do so.
Take care,
Jeremy
