It looks to me as if you missed updating your -sun copies fromGERONIMO-2398 which created the client-transaction config.

No, I had updated them for that, which why this was so puzzling.

I have 2 suggestions:
- try using the artifact_aliases.properties to replace client-systemwith client-system-sun. Then you won't need copies of all the otherstuff in between that and client-corba. You may find the bugs I thinkmust be in the use of artifact_aliases :-) which will be a good thing.
- try using the same *-system configs for yoko and sun, and usedifferent assemblies that do or don't include the yoko jars. Throughfrequent painful experience I have convinced myself that the serverhas no problem starting when the jars listed in the *-system manifestclasspath are completely missing.
- and a question.... can we include these endorsed jars in the *-corbaclassloaders rather than the *-system classloaders? Neither one is avery primordial classloader, so I would think either one would work.

This is how I ended up fixing the problem. I kept the classpath entriesin the *-system configs the way they are, then in the yoko configs,created a new set that included the yoko jar files. This was a muchsimpler solution, and avoided all of the classloading problems. I'venow got a build with both yoko and sun *-corba configs. I've got acouple of other things to clean up first, then I'll see what needs to betweaked to allow one or the other to be selected in a single assembly.

Hope this helps, sorry I didn't get to looking at this sooner.

I've got a class loading problem during the build that's driving menuts. I need to give a bit of background info first, so bear with me.
The situation:
I'm trying to get Geronimo to build with one set of client/j2eeconfigs that use the Yoko ORB, and one set using the Sun ORB. I gotthe existing configs converted to the Yoko ORB and building, and nowI'm working on a set of configs for the Sun ORB. To do this, I madenew client-corba and j2ee-corba configs. The endorsed classes areplaced on the classpath in j2ee-system and client-system, so I neededto create sun-specific configs for these two, plus client, server,client-security, and j2ee-security. The changes are very minimal.The *-system pom.xml files just remove the yoko class pathdependencies, the *-corba jars switch the ORBConfiguration GBean tothe sun version. The rest of the changes are just to the artifactids and parent configs. For example, the only difference between theclient-sun and client configs is the artifact name of "client-sun"and its dependency on "client-system-sun" instead of "client-system".All of this was building cleaning on Tuesday afternoon. On Wednesdaymorning, I did an svn update to keep up with changes, and now I'mgetting a build error due to a class loading problem while trying tobuild either client-security-sun or j2ee-security-sun. The yokoversions of these build fine. Here's the error:

This is a failure to resolve X509Name, which is in the geronimo-utilpackage. I have checked, double-checked, and triple-checked the pomsand the plans for all of these configs, and they should have exactlythe same dependencies. However, when I build client-security andclient-security-sun with the -X option, I'm able to see a differencewhen it processes the client-system-sun parent configuration:

I see that the client-security-sun config is missing thegeronimo-util jar file from the classpath, but is includinggeronimo-transaction and geronimo-connector, which the don't appearon the client-security classpath.I'm at a complete loss to explain why these are different. Theseconfigs should be using the same set of dependencies except for theyoko jars, but they're somehow ending up with different classpaths.I'm grasping at straws on this one now, so any suggestions aregreatly appreciated.
