[ http://jira.jboss.com/jira/browse/JBRULES-557?page=comments#action_12347660 ] John Cocktolstoy commented on JBRULES-557: ------------------------------------------ Hi, Currently I am developing application where all facts are instances of dynamically generated classes. Classes are generated based on model created in runtime by GUI. I am using Javassist to create classes and I am providing custom classloader that is passed to Drools, which can find new classes. Unfortunately this issue prevents me from further development. What are perspectives of fixing this issue? Is there any information when version 3.0.5 will be available? regards John C. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

Committed revision 7857. Although, I must warn that it will be easy to make it work with JANINO, but if you are using JDT as the compiler, you will need to implement a special classloader for your dynamically generated classes. This classloader must be able to provide the classes bytecode for the classes it handles, as JDT requires the actual bytecodes to compile the rules. So, to be short, your classloader must implement the method: public InputStream getResourceAsStream(final String name) { if( name is a dynamically generated class ) return <bytecode for the given dynamically generated class> else return super.getResourceAsStream( name ); } I have a sample code that works and will provide instructions later on how to do it. Need to clean it up first. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
