Subject Re: [Disscussion] Reference binded in JNDI is not dereferenced properly when lookup
Date Thu, 14 Apr 2011 04:13:14 GMT
>From the codes in DataSourceBuilder, the jndi reference is with prefix
aries:service, so there should be something like an ObjectFactory would take
care of it. I could see a service org\apache\aries\jndi\url\Activator.class
support this schema is registered in the activator, I simply compared that
Java file between 0.2 and 0.3 seems that some logic is changed, think this
should be a place to begin the debugging.
Hope it helps.
