drools-ant task and java.lang.ClassCastException: org.drools.reteoo.ReteooRuleBase  
------------------------------------------------------------------------------------

                 Key: JBRULES-1327
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1327
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 4.0.3
         Environment: Windows XP / Eclipse 3.2 
            Reporter: Brugger Antony
            Priority: Blocker


I try to use the drools-ant task to generate a package file like this:
	<target name="rules2" >
		<rulebase 
			srcdir="../src/main/rules" 		
			tofile="../rulePackage/bcpRules.rules"
			classpathref="bcp.classpath" > 
			<include name="testRuleBcp.drl" />
		</rulebase>
	</target>

it is working.

But when I try to use it in my Java code with this code:

		RuleAgent agent = RuleAgent.newRuleAgent("/ruleAgent.properties");
		RuleBase ruleBase = agent.getRuleBase();

ruleAgent.properties file:
##
## RuleAgent configuration file 
##
dir=./rulePackage
poll=30
name=MyBcpConfig

I have the following exception:
RuleAgent(MyBcpConfig) INFO (Thu Nov 15 16:16:20 CET 2007): Configuring with newInstance=false, secondsToRefresh=30
RuleAgent(MyBcpConfig) INFO (Thu Nov 15 16:16:20 CET 2007): Configuring package provider : DirectoryScanner scanning dir: .\rulePackage found 1 file(s).
java.lang.ClassCastException: org.drools.reteoo.ReteooRuleBase
	at org.drools.agent.FileScanner.readPackage(FileScanner.java:109)
	at org.drools.agent.FileScanner.getChangeSet(FileScanner.java:79)
	at org.drools.agent.FileScanner.loadPackageChanges(FileScanner.java:57

Indeed when I look at the code:

- in the ant task org.drools.contrib.DroolsCompilerAntTask, this is a RuleBase object that is serialized:
	private void serializeRulebase(RuleBase ruleBase)
			throws FileNotFoundException, IOException {
		ObjectOutputStream outstream = null;
		try {
			FileOutputStream fout = new FileOutputStream(toFile);
			outstream = new ObjectOutputStream(fout);
			outstream.writeObject(ruleBase);
		} finally {
			if (outstream != null) {
				outstream.close();
			}
		}
	}

- in the ruleAgent  class org.drools.agent.FileScanner is expecting a Package object to deserialized at line 109:
	            p1_ = (Package) in.readObject();

hence the ClassCastException...
