JAR file differences

Hi All,

I've a question regarding the difference in contents between 2 ojb 1.0.3
jar files.

I extracted the contents of an ojb jar from a jetspeed distribution and
found that it contained 7 extra class files compared to a jar I built
from source.

I've listed these class files below. 

	org/apache/ojb/jdori/sql/Helper.class   
	org/apache/ojb/jdori/sql/OjbExtent.class   
	org/apache/ojb/jdori/sql/OjbFieldManager.class   
	org/apache/ojb/jdori/sql/OjbStoreConnector.class   
	org/apache/ojb/jdori/sql/OjbStoreFatalInternalException.class   
	org/apache/ojb/jdori/sql/OjbStoreManager.class   
	org/apache/ojb/jdori/sql/OjbStorePMF.class  


As you can see, they're all to do with jdori. Does anyone have any idea
why the jar file I built from source does not contain these additional
files. 

Thanks,

Michael
