Problems deploying a detonated WAR to a Tomcat 6 server in IntelliJ Idea 12.1.4 Ultimate

I am trying to debug a web application in IntelliJ Idea, which is deployed on a local Tomcat 6 server as an exploded WAR.

At the beginning of the application, I get ClassNotFoundExceptions even if the exploded WAR directory contains these classes (in the WEB-INF/classe subdirectory).

When I launch the web application in IntelliJ Idea (click on the Debug 'Tomcat' button) and look in the Tomcat webapp directory ( C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps ), I don’t see the directory with my exploded WAR there.

Therefore, I think that the exploded WAR is not copied to the appropriate Tomcat directory.

How can I fix this (make sure Tomcat sees all the class files from my exploded WAR directory)?

Here's the stack trace:

I have a similar application, which seems to be a maven project, and by default uses the target (output) directory. However, this can be verified:

  • Locate the following line Using CATALINA_BASE: "C:\Users\xxxxx\.IntelliJIdea12\system\tomcat\Unnamed_bpt_5" in the startup Using CATALINA_BASE: "C:\Users\xxxxx\.IntelliJIdea12\system\tomcat\Unnamed_bpt_5"

  • Change to the directory indicated in the log message, then to conf\Catalina\localhost

  • Open xml from folder and check docBase

Also, make sure that on the Run/Debug configuration page, in the Before launch section, you add a Make target (or maven package) so that it compiles your classes and resources
