It sounds like you are still using the Struts 0.5 tags.  There isn't a
tag named "ifParameterExists", although the following tags exist:
ifParameterEquals, ifParameterNotEquals, ifParameterNotNull,
ifParameterNull.

In Struts 1.0, you would use

    <logic:present parameter="xxx">

to test for the presence of a request parameter named "xxx".
