[rules-users] drools-ant task and java.lang.ClassCastException: org.drools.reteoo.ReteooRuleBase

[Ojwang Wilson O]

All,

I was succesfull in building rules pkg from drl using drools-ant task, 
but when I used the generated pkg in the code below

=============
            File rulesDir = new 
File("/home/droolsuser/workspace_ant/AntDroolsTest/build/pkgrules/");
            String rulesdir = rulesDir.getAbsolutePath();
            Properties prop = new Properties();
            //prop.setProperty("file", ruleFile);
            prop.setProperty("dir",rulesdir);
            prop.setProperty("newInstance", "false");
            prop.setProperty("localCacheDir", ".");
            prop.setProperty("poll", "300"); // poll every 300 seconds 
for hot deployment.
           
            //Get a new RuleBase using these properties
            RuleAgent agent = RuleAgent.newRuleAgent(prop); 
-------------------->Error line
            RuleBase ruleBase = agent.getRuleBase();
==========

I encountered the following error.
=========
     [java] RuleAgent(default) INFO (Mon Jul 07 18:58:30 CDT 2008):

=====

In looking at 4.0.7 code, the  RuleBase object in ant task 
org.drools.contrib.DroolsCompilerAntTask is serialized, but the p1_ = 
(Package) in.readObject(); in the class org.drools.agent.FileScanner is not.

Any solution around this problem?

Thanks in advance for your professional help.

Wilson
