Re: [Springframework-developer] is LazyInitTargetSource on factories possible?

Juergen,

we need to run to separate webapps which are integrated via WS on the 
same tomcat (client's choice), so checking the WSDL at startup is not an 
option. A configurable setting of the WSDL checking would be a perfect 
solution for that problem.

I don't have the application context code anymore and it's not in our 
CVS either as it wasn't working, but I remember explicitly specifying 
cglib proxying for that scenario and that's what failed. I needed a 
quick solution so I separated the WS-integration beans into a separate 
config file and loading it lazily from the caller manually using the 
ApplicationContextAware interface, but that's really a workaround, not a 
solution for the problem.

regards,

Kristof
