Question

I’m running Google Apps locally via eclipse. I connect to http://localhost:8888/ and sometimes Eclipse will throw an exception from this line 374 in AccessControlContext.class:

    throw new AccessControlException("access denied "+perm, perm);

Here is the stack trace:

Logger.log(Level, String) line: 523 
Logger.warning(String) line: 1026   

I’m calling just this:

    log.warning("string");

and log is initialized like so:

    private static final Logger log = Logger.getLogger(MyServletName.class.getName());

What is breaking?

Answer 1

Try using this line instead. I normally use something similar to the following line when I write GAE code:

private static final Logger log = Logger.getLogger(MyServletName.class.getSimpleName());

So, use getSimpleName() instead of getName(). Read java.lang.Class javadoc on getName() and getSimpleName(). The former probably appends an ‘L’ character to the end of the class type name, while the latter does not possess this (in your situation, undesirable) behaviour.

Also, consider using Guice Injection for the class’s Logger object.
