Injecting DAOs in OpenNMS

Posted by hatim Sat, 09 Aug 2008 22:13:00 GMT

In my Summer of code project I have to use already established DAOs (well some times adding a few tid bids) and using them to replace JDBC code. Testing DAOs with Hibernate tools made it alot easy to play with both HQL and criteria, but I was stuck when it came to injection. It seems that OpenNMS uses lots of technologies like JMX which I have never even touched before

attached is a log of a conversation which I had with a devel on #opennms. Based on this conversation I some how was able to bug the devel into writing all of this into a wiki page.

There was one small confusion though, I was working with Poller which was infact Pollerd, there being a naming inconsistency. Following this wiki page I should be now able to easily inject Dao's to my required daeomons and other classes.
