I am having problems using functions in my .drl file. &nbsp;When I add a function, I get the following two errors: <br><br>ImportError: PackageName.Function.function <br>Syntax error, static imports are only available if source level is 
5.0 <br><br>Has anyone else seen this? &nbsp;I am using Eclipse 3.2.2, Eclipse Drools IDE 4.0.3, and JDK 1.4. &nbsp;It appears as though I can&#39;t use the IDE unless I&#39;m at JDK 5.0??? <br><br>One interesting thing is that if I modify my &#39;Compiler compliance level&#39;, &#39;Generated .class files compatibility&#39;, and &#39;Source compatibility&#39; settings to 
1.4, the .drl compile errors go away. &nbsp;But as soon as I close Eclipse and reopen it, the errors show up again.&nbsp;&nbsp;I appreciate any help you can provide!&nbsp;&nbsp;Thanks.
