Hello.<br>
<br>
Although without much conviction, I've tried the<br>
"Bundle-RequiredExecutionEnvironment: J2SE-1.7", but it doesn't change the<br>
compilation level of the rules...<br>
<br>
As I said in a previous answer, I don't know exactly how to do it, but I<br>
think the solution may be in the way that Drools takes the classloader<br>
passed by the application to have access to specific classes like the<br>
usually imported beans used in the rules. Indeed, perhaps that instead of<br>
using directly this classloader, for its tasks, among of them the rules<br>
compilation, it should be possible to use some kind of enriched classloader<br>
that carries all the Drools needed packages, and delegates application<br>
classes resolution to the application's one.<br>
<br>
What do you think of that ?<br>
<br>
Regards.<br>
