Tomcat 5.5<BR>
Java 1.5<BR>
jbossrules-4.0.0.12865MR3<BR>
<BR>
I have an instance of Drools running inside a webapp deployed on Tomcat. The rules have been compiled ahead of time and are loaded in with:<BR>
<BR>
InputStream is = PolicyRuntime.class.getResourceAsStream(name);<BR>
DroolsObjectInputStream in = new DroolsObjectInputStream(is);<BR>
Package p = (Package) in.readObject();<BR>
<BR>
When run outside Tomcat it loads fine, when run inside Tomcat I get:<BR>
<BR>
java.lang.NoClassDefFoundError: org/drools/base/extractors/BaseObjectClassFieldExtractor<BR>

<BR>
I've tried adding DroolsObjectInputStream.class.getClassLoader() , PolicyRuntime.class.getClassLoader() and Thread.currentThread().getContextClassLoader() to the constructor of the DroolsObjectInputStream but none had any effect.<BR>
<BR>
Thanks<BR>
