Re: WOInject failure with WOMonitor

Hi,

funny thing I've got the same error at startup on my recently woinjected
App in deployment only (woinject v1.0.1) :

Caused by: javassist.NotFoundException:
com.webobjects.foundation._NSUtilities
at javassist.ClassPool.get(ClassPool.java:450)
at com.woinject.WOInject.init(WOInject.java:66)
... 6 more

I have no clue what's wrong. All the needed jar's are in the classpath.
Looks like there's some class loader issue in there, is there something I'm
not aware of ? The WOBootstrap.jar must be the one from the wotaskd 5.4.3 ?

Thanks for your help,

Alex
