RE: [aspectj-users] Exception in thread "main"java.lang.NoClassDefFoundE

["Buck, Robert" <rbuck@xxxxxxxxxxxx>]

Hi Andy,

Okay, so I reverted back to double-dots. The doc was not very clear,
which is why I tried single-dots. But still, I get the same error:

Exception in thread "main" java.lang.NoClassDefFoundError
	at $AllProbeAspect.aspectOf(Unknown Source)
	at
com.verisign.common.properties.PropertyManager.getInstance(PropertyManag
er.java:81)
	at com.verisign.jtaps.test.Test.calc(Test.java:19)
	at com.verisign.jtaps.test.Test.main(Test.java:29)

Notice that there is no class name specified; when I trap all exceptions
in the debugger, what I see is a null error message, and the causation
member self-references the lexically enclosing exception instance, as if
somewhere someone did something evil like:

  NoClassDefFoundError error = new NoClassDefFoundError();
  error.initCause(error);
  throw error;

The information I Google'd did not turn up any hints that worked.

What sort of approach might I use to dianose and resolve this issue? 

Thanks in advance,

Bob

In AspectJ syntax, the expression

pkg.*

means any type in package 'pkg'.  If your type is in pkg.subpkg then it
will not match that expression.  Two dots are needed to include types in
the package or any sub-package.

pkg..*

Going by the aop.xml in your previous email, you are using
org.apache.log4j.*  and that doesn't match
org.apache.log4j.spi.RootLogger, so it is not excluded from the weaving
process.

The doc is here:
http://www.eclipse.org/aspectj/doc/released/devguide/ltw-configuration.h
tml
but i'll say that if you aren't familiar with the double dot notation,
it isn't explicitly indicated there as what you need to use, and the
example on that page is a bit unclear.  we could do with improving that
doc.

cheers,
Andy.
