Struts Validator throwing InvocationTargetException

[Thomas 'Skip' Hollowell]

<form name="/dynPrepaidHistory">
<field property="endDate" depends="mask">
<arg0 key="validation.history.enddate.required"/>

<var><var-name>mask</var-name><var-value>^((19[0-9][0-9]|2[0-1][0-9][0-9])-(0?[1-9]|1[0-2])-(0?[1-9]|[12][0-9]|3[01]))$</var-value></var>
</field>
<field property="startDate" depends="mask">
<arg0 key="validation.history.startdate.required"/>

<var><var-name>mask</var-name><var-value>^(yyyy-mm-dd|((19[0-9][0-9]|2[0-1][0-9][0-9])-(0?[1-9]|1[0-2])-(0?[1-9]|[12][0-9]|3[01])))$</var-value></var>
</field>
</form>

The Validation is actually occuring, and is only allowing valid data
formats through (yyyy-mm-dd) where yy may or may not have a leading 0.

But I get the huge exception every time this fields is validated, and a
couple hundred lines are added to my log file....ideas of where to look
or what to look at are appreciated.

To answer my own question, the jakarta-org.jar file had inadvertently
been deleted from my lib directory. Replaced it and all is well.
