Not able to check for null condition
------------------------------------
Key: DROOLS-427
URL: http://jira.codehaus.org/browse/DROOLS-427
Project: drools
Type: Bug
Versions: 2.1
Environment: WINXP & Java
Reporter: Jagpreet Kaur
Assigned to: bob mcwhirter
I am using JSR94 and drools.
My rule.xml file looks :
<rule-set name="PunchRoundingAndDockingRule" xmlns="http://drools.org/rules";
xmlns:java="http://drools.org/semantics/java";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://drools.org/rules rules.xsd
http://drools.org/semantics/java java.xsd">
<import>java.lang.Object</import>
<import>java.lang.String</import>
<!--Rule to check that department is Null-->
<rule name="Checkdepartmentfornull">
<parameter identifier="department">
<class>String</class>
</parameter>
<java:condition>
department==null
</java:condition>
<java:consequence>
System.out.println("department is null");
</java:consequence>
</rule>
</rule-set>
I am passing department as null but the following condition is never check and
I am not getting any exceptions but
also not getting the "department is null" message on the console. How can I
check for null
condition?
