Re: [rules-users] Drools function not working with Javassist facts

The problem definitely depends on msgCtClass.writeFile(); being in the code AND the root (!) of the subdirector drools/dynamic into which the class file Message.class is written being in the classpath. Since I run javac/java from the comman line, I have to have "." in my classpath, and this means that ./drools/dynamic/Message.class is in scope. See where this subdirectory+file is actually located in your workspace and make sure the root is in the classpath. Check the javassist API so as to exercise more control over the location to which the class file is writen by the aforementioned method. -W On 22/05/2012, Ayush <ayush.vatsyayan(a)alcatel-lucent.com&gt; wrote:
