commons-logging.jar not loaded [message #77249]

I run TPTP Junit plugin test for my plugin. Here is the setup.

Plugin xyzlib contains the commons-logging.jar
Plugin abcPlugin has some simple code which uses classes provided by
common-logging.jar

In plugin xyzlib I've exported the commons-logging.jar from the Project
Properties sheet. I've also added the jar to the Classpath in the
Runtime tab of the Manifest editor. Also, I've exported the packages to
all downstream plugins.

Now my plugin abcPlugin has some (plain) Junit tests, which I can run
using Run > Run as Junit Plugin Test. There are no problems and my code
can find the classes from the commons-logging.jar

Problem is when I Import the same tests TPTP Junit Plugin tests and try
to run then my code throws a Runtime NoClassDefFoundException.

I tried to debug and found that in BundleLoader.class, in the method:-

Class findClass(String name, boolean checkParent) throws
ClassNotFoundException

after these lines:-

// 4) search the required bundles
source = findRequiredSource(pkgName);

the source variable:-
source > supplier > loader > classloader > classpathentries

has the entry for commons-logging.jar in case of Junit Plugin Test
BUT
does not have any entry in case of TPTP Junit Plugin Test.

Forgot to add this:-
I'm using eclipse 3.1.2 with TPTP 4.1.0.1, Sun Java 1.5 OS is FC3-linux

Also, TPTP uses the commons-logging.jar itself, so it might be causing
some conflict and hence the commons-logging.jar is not loaded by the
class loader when my code requests it.

Are these any useful links:-
http://www.qos.ch/logging/classloader.jsp
http://help.eclipse.org/help31/index.jsp?topic=/org.eclipse. hyades.test.doc.user/tasks/tdeploymentGroundRules.htm
For the second link, the Excluded Libraries topic seems interesting. But
I have no idea why isn't this 'issue' resolved.

I made my plugin dependent on org.apache.jakarta_commons_logging and
evrything worked fine. But this is not how I want to do it. I want the
commons-logging.jar api to be available through my plugin only.

Please Help !!

Hi Prince,
This is not related to the org.apache.jakarta_commons_logging plugin
that ships with TPTP. This is a defect in that the TPTP execution harness
is not deploying the commons-logging.jar from the abcPlugin. You can
confirm this by checking if the commons-logging.jar is in the <user temp
directory>/<user name>/ directory tree. Your solution (making the abcPlugin
dependency on org.apache.jakarta_commons_logging plugin) will solve the
problem or you can create an artifact (Help >> Help Contents >> Testing
applications >> Testing with JUnit >> Running a JUnit test remotely) with
the commons-logging.jar set on the CLASSPATH property of the artifact. That
said, these are only suggested work-arounds. Please open a TPTP defect
( https://bugs.eclipse.org/bugs/enter_bug.cgi?classification=T PTP) for this
problem.
