I have been using Tomcat 5.0 for some time now and everything works well. We have a new client that requires that our application run on Resin. I have thus far worked through several problems successfully, but am currently stuck. When I start the Resin server, I see approximately 100 errors coming from 2 of the jars we deploy to our web application:

.All of the necessary jars are deployed to the lib directory. What;s with these errors?
Also, have you added support yet to deploy to the WEB-INF directory instead of “deploy”?

That’s a really good question. I haven’t seen anything like this before. Can you open the jars with WinZip or something and make sure the classes are in the jar under the correct path, based on their package declarations and that the archives haven’t become corrupt. Can you start Resin from the commandline to see if the results are any different? Can you take a war that works in your Tomcat install, drop it in Resin, start Resin from the commandline and see if that makes any difference? If it does, try leaving that deployed and starting Resin from MyEclipse. What did that do?
Also, have you added support yet to deploy to the WEB-INF directory instead of “deploy”?
You can deploy to whatever directory you like using the Custom Location deployment targets instead of one of the server targets.
I tried manually starting the resin server, but hit the same error. I then downloaded a slightly newer version of those 2 jar files. I have not seen the problem reoccur yet, but that may be because I am not getting as far. I am having a lot of trouble with the redeploy. Not everything is getting copied out to the server. It seems to vary as to how much is copied over. Sometimes almost everything is copied. Sometimes the application folder is compledtely empty. And sometimes just a few of the files are copied. I am not seeing any kind of deployment error. I saw this happen once before I experienced the reported problem. Not sure what to make of it. I’ll try exiting eclipse again.
When I do a project clean, I noticed that class files appear, then for some reason deleted. Only the class files from my web project are remaining at this time. The dependent project class files are getting deleted during the process. Are we allowed to deploy to more than 1 server? Could that be causing me trouble. I also noticed that at least one of the field deployed to Resin has a lock left on it, causing redeploys to fail until I reboot.
I undeployed both projects. Performed a clean of all projects. Deployed to the Resin 3 server. Still the same problem. It appears that only the class files from my web project remain on the Resin server. Most of my code is in a dependent java project. When I perform another project clean, all of the class files from the dependent projct appear briefly on the Resin server. But by the end of the clean cycle, they are deleted again.
I believe I have fixed my deployment problem. I was pointing to the wrong dependent project in my web project (properties – project references). The newer versions of jcommon and jfreechart are also working without error. I can successfully start the Resin 3 server.
My only outstanding question is:
Where is the Custom Location Deployment feature? Is it available in 3.8.5? Or do I need to upgrade to 4.x.x? And is 4.x.x considered a stable environment for development?
Spoke too soon. Not everything is being deployed. This is a problem I mentioned earlier before my properties were messed up. I keep hitting a java.lang.NoClassDefFoundError error because one of my inner class files is missing. I am noticing the error when I try to bring up my initial web page. Not all inner class files are missing. Just a few. If I redeploy to try to correct the problem, a different inner class file will be missing.
