Re: [eclipselink-users] Class Weaving

[Tom Ware <tom.ware@xxxxxxxxxx>]

Hi Guarav,

  What symptoms are you seeing that indicate you are not getting weaving?  Are 
you certain that some classes are getting weaved and some are not?

  Here are some things you can do to get started debugging.

- Set logging to FINEST (eclipselink.logging.level=FINEST)
- When EclipseLink starts weaving a class it will log the string "Begin weaver 
class transformer processing class" + className and when it ends weaving, it 
will log the string "End weaver class transformer processing class" + class. 
Look for those logging strings with the classes you suspect are not being weaved 
and see if any errors are logged between those strings.
- There are some debug flags that can be set as System properties that will 
allow you to output the weaved classes. (eclipselink.weaving.output.path=<path> 
and "eclipselink.weaving.overwrite.existing=true").  If you set those flags, you 
should be able to see the classes that are weaved.  A decompiler will show you 
the source.
- Successfully weaved classes will implement the 
org.eclipse.persistence.internal.weaving.PersistenceWeaved interface.  Check for 
it on your suspect classes.

-Tom
