I'm running Tomcat 7.0.19 with IntelliJ IDEA IDE. I'm using the new Servlet 3.0 feature that allows webapp resources to be served from within JARs' META-INF/resources directory. This technique is working fine, however I would like to be able to "hot swap" these resources at runtime in a local development environment using my IDE. That is not working.
In my scenario, I have two artifacts in IDEA. One is a webapp that produces a WAR (I'm deploying this as an exploded war to tomcat). The other is a JAR with some JavaScript / CSS / HTML and JSP resources. The webapp includes the JAR. When IDEA deploys the webapp it compiles creates the JAR from the second artifact and plops it in the exploded webapp's lib folder. It then starts up tomcat and points it to the exploded webapp folder. This works perfectly. Then, while tomcat is running, I make a change to one of the resources in the JAR and tell IDEA to update classes and resources. I can see on disk that IDEA puts a new version of the JAR in the libs folder. The JAR has an new modified date. If I unzip the JAR, I can see that it contains my changes. However tomcat is still serving up the old version of the file. The same thing happens whether I update a file or add a new file. The behavior is also the same for both static files and JSPs. Note that updates work fine for resources in the webapps root directory, it's only the resources inside JARs that don't reload. Also note that the updates do come through fine once I restart tomcat or reload the webapp; however I would very much like to avoid having to do that. Is this a Tomcat bug, missing feature, or is there something IDEA is doing incorrectly? Thanks. -- David Wolverton | Vodori Inc | david.wolver...@vodori.com | (w) 312.324.3963 | (c) 773.571.3750
