I am using the common configurnation, first I found the error message which
tell me the class org.apache.commons.lang.exception.NestableException can
not be resovled, so I download the common lang jar, then this error does not
exist,however another message:java.lang.NoClassDefFoundError:
org/apache/commons/collections/Predicate
Then I get a message box " can not find the main class,Program will exit "
I wonder why, does it mean I should add the common collection jar? if so
,how many jars I need to add ?
