Can't redeploy application (using JAXB)

Question

I can't redeploy my application on Tomcat 7 on Windows. It attempts to undeploy the app but one file cannot be deleted: jaxb-impl-2.1.13.jar. I then cannot deploy the app again because the file is present.

If I restart Tomcat, I can deploy the app.

This is what I get in the log:

Oct 08, 2013 12:00:28 PM org.apache.catalina.startup.HostConfig deleteRedeployResources
INFO: Undeploying context [/myApp]

I don't get this problem on Linux, only on Windows. How can I release this file so I can redeploy my app?

Answer 1

I just get clear about this problem. For the reason about locking issue, you could check apache wiki.

One of the way to resolve this problem is configuring the following properties of Context tag in context.xml:

• antiJARLocking="true"
• antiResourceLocking="true"
