You could have an error in your SqlMapConfig.xml. Change the catch block in
your static initializer to catch Exception and print the stack trace or use
a debugger as Larry suggested.

Yes, I agree with you, but I couldn't see anything wrong with BaseIbatisDAO
. 

Thanks.

Re: java.lang.NoClassDefFoundError error again, need help!

	




I'd guess that the BaseIbatisDAO is failing to initialize properly, then
causing the exception you are seeing - if the initialization fails, the
class does not load, so later classes that rely on it can't find it.

I'd look there for issues - maybe step through it with a debugger.
