I look at Guess.rf the xml file. I notice the Package and Import locations are pointing to the old location. After I change them to the new one by hand. The code works. How can I change the above in Eclipse GUI interface?

Sorry, I gave you instruction for the imports and globals… - Open the Properties view in Eclipse - Select the background of the flow (unselect any selected items) - The Properties view should refresh - The package property should be available for edit in the view *From:* rules-users-bounces(a)lists.jboss.org [mailto: rules-users-bounces(a)lists.jboss.org] *On Behalf Of *Tak-po Li *Sent:* Wednesday, June 10, 2009 4:50 PM *To:* Rules Users List *Subject:* Re: [rules-users] re: NumberGuessExample I do not get it.

That is what I did: 1. Make a project "try" that generates the HellowWorld for me in Eclipse. 2. add directory "log" 3. Move file Guess.java to the Java/com/sample directory.
