Subject [beanutils] Re: cvs commit: jakarta-commons/beanutils/src/test/org/apache/commons/beanutils ConstructorUtilsTestCase.java TestBean.java
Date Wed, 27 Nov 2002 19:17:01 GMT
hi Rodney

sorry to be a PITA but...

we're trying to move the basic reflection code (as opposed to 
introspection) into lang. there is already a ContructionUtils in there as 
well as a MethodUtils (which will hopefully in the end replace the one in 
beanutils).

would it be possible to move this code into lang and work together on an 
improved version there?
