Very weird problem

[James Daniel]

I am experiencing a very weird problem. I have created a jar containing many classes to be called via Groovy within Hudson/Jenkins or via commandline to main method. I used the Maven Assembly plug-in so all the dependencies are contained within. It works great on most methods. The "weirdness" is when I try to call a DAO object that utilizes org.apache.commons.beanutils.RowSetDynaClass. When I instantiate the RowSetDynaClass constructor, I get method does not exist. This ONLY occurs when calling via Groovy. It does not happen when I call via commandline. Anyone know why is this occurring?
