It is a java date. We use some java binding objects to build it. Below is just a sampling of this. The second entry below indicates what to name it in Java, it's java type, what DB2 table (cogentTable) and data field it is coming from (cogentField). The snippets below might not help much.

1) bindHistory((ECDField) object.getElement("dateOfBirth"), this.getDateOfBirthHistory());

2) <attribute name="dateOfBirth">
<type>Date</type>
<cogenTable>W1V0</cogenTable>
<cogenField>BIRTH-DATE</cogenField>
<description>Date Of Birth</description>
</attribute>

Hello Laun,

Thank you for your quick response. This date is a date coming from a DB2 date field and is valid in my incoming data. Frankly, I am with you, why not null versus a silly low date as such, arggggh. But since it is coming in as such do you know of a work around?

Thank so much,
Nancy

Why would you want to test for January 1st in year 1? This is not a
value an object of type java.util.Date can represent. See that type's
javadoc for details, but the epoch begins January 1, 1970.

I have a simple rule where I want to bypass elements that have a low date but
drools seems to be interpreting the date different then I am expecting.
Drools statement and error follows:

ClientSupplement ( dateOfBirth : dateOfBirth != null && != 0001-01-01)

throws error -- Error: [Error: badly formatted number: For input string:
"001-01-01"] [Near : {... 0001-01-01 ....}] ^ [Line: 1, Column: 1]

How do I get drools to understand this low date? I have tried single,
double, and no quotes around the low date and all result in a similiar error
message. Please Help!
