RE: HOW TO: re-deploy or undeploy a webapp when additional files are added after initial deployment
Also - I just looked at my local tomcat 6.0.32 server.xml and it has JreMemoryLeakPreventionListener on the Server element. The implicit disabling of URL caching this is supposed to do must not have an effect on this scenario. As an aside, when I used antiJARLocking + antiResourceLocking on the server's context.xml, it appeared to work, but that has other documented side effects - such as creating a bunch of garbage in the tomcat/temp directory. As a result, this really isn't a solution for us. Any suggestions on how we can get these JAR(s) not to be locked - without using the context attributes?

Tomcat 7 will report if it can't delete a file. I don't recall if Tomcat 6 does. If a file is under the docBase and is not deleted it is because something (probably your app) still has the file open.

RE: HOW TO: re-deploy or undeploy a webapp when additional files are added after initial deployment
Hi Mark, Actually, in the logs it does tell me that ExpandWar deleteDir failed. This is because my "extensions" I have are actually JAR files that we're dynamically loaded so we don't have to restart the webapp. I'm using the addUrl hack, but by casting the main webapp's Thread.currentThread().getContextClassLoader() to a URLClassLoader. From a dynamic loading standpoint, it works great! It allows extension classes in an extension JAR to derive from classes in our built-in product JAR(s) loaded by the same [I'm assuming] webapp classloader. The problem is, when I shutdown/undeploy the webapp, everything else gets deleted, but not the JAR(s) that are dynamically loaded. Tomcat should not be holding on to these because I am NOT using the System class loader to load them. Problem is, I'm not sure why these are not being unloaded.

Thanks, but I need to do this in a production environment, where we're deploying/re-deploying a WAR and there is no eclipse IDE. In addition, I am dynamically adding extensions to our webapp without having to restart our webapp, which is what republishing from Eclipse does. -bob -Original Message- From: Chema [mailto:demablo...@gmail.com] Sent: Monday, August 01, 2011 3:02 PM To: Tomcat Users List Subject: Re: HOW TO: re-deploy or undeploy a webapp when additional files are added after initial deployment > If anyone has any suggestions on how we can add files into the exploded > webapp structure and still perform undeploy/re-deploy of our webapp, I would > greatly appreciate it.
