JSP Precompilation Errors

[Neuman, Ben J., A&M IRM]

I have a struts web-app (Struts 1.2.4, J2EE 1.3, Servlet 2.3, JSP 1.2) in
which the JSPs fail to compile. All of the exceptions are of the flavor
"cannot be applied to":

"_jspx_method_some_tag_#(someTag, java.servlet.PageContext) in
org.apache.jsp.xxx.some_jsp cannot be applied to (org.apache.SomeTag,
javax.servlet.jsp.PageContext)"

Here is one exception word for word and the associated JSP:

D:\dev\HRMS\Modules\WebModule\build\generated\src\org\apache\jsp\common\mess
agePane_jsp.java:105:
_jspx_meth_bean_write_0(javax.servlet.jsp.tagext.JspTag,javax.servlet.jsp.Pa
geContext) in org.apache.jsp.common.messagePane_jsp cannot be applied to
(org.apache.struts.taglib.html.MessagesTag,javax.servlet.jsp.PageContext)
              if (_jspx_meth_bean_write_0(_jspx_th_html_messages_0,
_jspx_page_context))

............................................................................

    <%@ taglib uri="/struts-bean" prefix="bean" %>

    <%@ taglib uri="/struts-html" prefix="html" %>

    <%@ taglib uri="/struts-logic" prefix="logic" %>

    <div id="messagePane">

    <logic:messagesPresent message="true">

    <table cellspacing="1" cellpadding="1" border="0" width="100%">

    <tr>

        <td>

        <table width="100%" align="center" border=0>

            <tr>

            <td><html:messages id='message' message='true'>

                    <bean:write name="message"/>

                </html:messages> 

            </td>

            </tr>

        </table> 

        </td>

    </tr> 

    </table>

    </logic:messagesPresent> 

    </div>

I have a suspicion that this is a classpath problem and not related to
Struts directly, however, any help would be greatly appreciated. 

Thanks!
