Stuck: Application Client launching in 9.0.3 and 1.0.2.2.1

Question

Ok, I have read the decent amount of material but I still can't get my test client to launch in the containers.
In 1.0.2.2.1 I am unsure what my client name should be. Here is my commmand
java -jar applicationlauncher.jar ormi://localhost:23841/appName/clientAppName oc4jadminuser adminUserPassword
Now, I know that app name is the name of the deployed application. But where do I define/find the client app name. Everything, i have read says I need to use that command line. But nothing tells me what the client app name is. my clientApp is deployed in the application as triggertest.jar. So does that mean my client app name in the container is triggertest? When I try to use that as the clientAppName I get:
No Manifest found even though I do have a mainfest file. Am I missing something here?
Further, I also have a 9.0.3 install of OC4J. When I try to run the application there I get an even more confusing error stating:
Exception in thread "main" java.lang.NoClassDefFoundError: com/evermind/client/applicationlauncher/ApplicationLauncher
This is so frustrating. I would like to make use of the JNDI features and such in the application but I can't even make this work.

Hi Matt,
I've been having trouble connecting to these forums in the last few days.
It's been a while since I used "applicationlauncher.jar", and I'm not at work right now (so I can't verify), but the manifest file format needs to be exact, otherwise the java application doesn't work (and you really don't understand why). I know that there is an issue with a trailing new line in the manifest file -- but I don't remember if you have to include it or not. Have you looked at the JDK documentation regarding the manifest? There is also some good information on the "Java Tutorial" (from SUN).
Also, if I remember correctly, OC4J version 1.0.2.2 supports JDK 1.2, but you seem to be using JDK 1.3 -- this may be causing problems?
As you noted (and I have mentioned in previous posts to the forums), "applicationlauncher.jar" disappeared in version 9.0.2.0.0 (of OC4J) and "made a comeback" in version 9.0.3 (yet Oracle discourages its use -- I wonder why).
So perhaps you should try using 9.0.3 and "applicationlauncher.jar" with JDK 1.3? This is just a suggestion -- I have only used "applicationlauncher.jar" with OC4J 1.0.2.2 and JDK 1.2.2 (on SUN [sparc] with Solaris 7)
Hope this helps you.
Good Luck,
Avi.
