[rules-users] ANT Compile issues

[Bhamidi, Krishna]

As an update, I changed JAVA_HOME to 1.5.0 (it was 1.6 earlier). I keep getting the same error. File is being recognised

RuleAgent(rules) INFO (Wed Apr 15 09:26:08 EDT 2009): Configuring with newInstance=false, secondsToRefresh=30

RuleAgent(rules) INFO (Wed Apr 15 09:26:08 EDT 2009): Configuring package provider : DirectoryScanner scanning dir: antBuild found 1 file(s).

Any pointers to what I should be doing?

Subject: [rules-users] ANT Compile issues

Hi,

I am using DROOLs 5.0.0 CR1 and use the compiler from Drools-Ant. When I attempt to execute the rules using a rule agent, I get an exception that in part reads

java.lang.NullPointerException
at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1820)

(Full stack follows this e-mail.) However, when I download the pkg file for the same ruleset from Guvnor and use it in the rule agent, it runs fine.

I use the following for building -

<taskdef name="compiler" classname="org.drools.contrib.DroolsCompilerAntTask" classpathref="compiler.classpath" />

<compiler srcdir="../${rulesDirectory}" tofile="../${buildDirectory}/${projectName}_rules.pkg"
 classpath="../${buildDirectory}/${projectName}_rules.jar"
 binformat="package">
 <include name="*.drl" />
 <include name="*.brl" />
 <include name="*.xml" />
 <include name="*.dslr" />
 <include name="*.xls" />
</compiler>

What I should do to compile correctly?
