Validating forms in struts

Question

Hi
I'm developing an application using struts and my web server is tomcat 4. i have a add page with different fields. How do i validtate these fields in struts. The following are my entries
struts-config.xml:
<action path="/AddOpportunitiesAction"
type="com.wipro.opportunity.ui.AddOpportunitiesAction"
name="AddOpportunitiesForm"
scope="request"
parameter="action"
     validate="true"
input="AddOpportunitiesAction">
<forward name="addOpportunity" path="/addOpportunity.jsp"/>
<forward name="DisplayOpportunitiesAction" path="/DisplayOpportunitiesAction.do"/>
<forward name="DisplayAccountAction" path="/DisplayAccountAction.do"/>
</action>
i have extended addopportunityForm as ValidatorForm. i have given the rules in vaidator.xml as
<form name="AddOpportunitiesForm">
<field property="opportunityName"
depends="required">
<arg0 key="addopportunity.name"/>
     </field>
</form>
The following entry show the getter setter method in addopportunityForm
public final class AddOpportunitiesForm extends ValidatorForm{
private String opportunity_name;
public void setOpportunityName(String name) {
this.opportunity_name = name;
public String getOpportunityName() {
return this.opportunity_name;
Note: IN addopportunity.jsp the property of my name field is opporutniyName and not opportunity_name
addopportunity.jsp
<td>
               Opp. Name <font color="red"> * </font>
          </td>
          <td>
               <html:text name="AddOpportunitiesForm" property="opportunityName"/>

Here is my code below.
my serverside validation is working fine but my client side validation doesnt work.
Struts config:
<form-bean name="courseCriteriaForm" type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="paperId" type="java.lang.Integer"/>
<form-property name="passingMarks" type="java.lang.Integer"/>
<form-property name="totalMarks" type="java.lang.Integer"/>
<form-property name="StudentListmarks" type="org.aptech.lms.common.StudentListMarks[]"/>
</form-bean>
<action
path="/displayCourseDetail"
name ="courseCriteriaForm"
scope = "session"
type="org.aptech.lms.admin.action.DisplayCourseMarksDetailAction"
validate="false"
input="/pages/admin/CourseMarksDetail.jsp">
<forward name="success" path="/pages/admin/CourseMarksDetail.jsp" />
<forward name="error" path="/pages/admin/CourseMarksDetail.jsp" />
</action>
<action
path="/updateCourseMarks"
scope = "session"
name ="courseCriteriaForm"
type="org.aptech.lms.admin.action.UpdateCourseMarksAction"
validate="true"
input="/pages/admin/CourseMarksDetail.jsp">
<forward name="success" path="/pages/admin/CourseMarksUpdateSuccess.jsp"/>
<forward name="cancel" path="/showUserRoles.do"/>
<forward name="error" path="/pages/admin/CourseMarksDetail.jsp"/>
<forward name="noerror" path="/pages/admin/MarksFail.jsp"/>
</action>
MY JSP
<html:form action="/updateCourseMarks" onsubmit="return validateCourseCriteriaForm(this);" >
<html:javascript formName="courseCriteriaForm"/>
<table class="tableborder">
<tr class="subtablerow2"><td class="boldtext">Total Marks : <bean:write name="courseCriteriaForm" property="totalMarks"/> </td>
<td class="boldtext">Passing Marks : <bean:write name="courseCriteriaForm"property="passingMarks"/></td>
</tr>
</table>
<table class="tableborder">
<html:hidden name="courseCriteriaForm" property="totalMarks" />
<logic:iterate id="StudentListmarks" name="courseCriteriaForm" property="StudentListmarks" >
<tr>
<td>
<bean:write name="StudentListmarks" property="userinfo_id"/>
</td>
<td>
<bean:write name="StudentListmarks" property="firstname"/>
</td>
<td>
<bean:write name="StudentListmarks" property="lastname"/>
</td>
<td>
<c:if test="${StudentListmarks.marks == '-99'}">
<html:text name="StudentListmarks" property="marks" indexed="true" value="NA" />
</c:if>
<c:if test="${StudentListmarks.marks != '-99'}">
<html:text name="StudentListmarks" property="marks" indexed="true" />
</c:if>
</td>
<td>
<html:text name="StudentListmarks" property="remarks" indexed="true"/>
</td>
</tr>
</logic:iterate>
</table>
<logic:present name="display" scope="session">
<div align="center"><html:submit styleClass="button"/><html:cancel styleClass="button" /></div>
</logic:present>
</html:form>
MY VALIDATION.XML
<form name="courseCriteriaForm">
<field property="marks" indexedListProperty="StudentListmarks" depends="required,mask">
<arg0 key="errors.marks.required11"/>
<arg1 key="errors.marks.mask"/>
<!-- <arg2 key="CourseCriteriaForm.totalMarks" name="totalMarks"/>-->
<!--<arg3 key="errors.validatemarks" name="validatemarks"/>-->
<var><var-name>mask</var-name>
<var-value>^[NA0-9]{2}[a-zA-Z0-9_ ]*$</var-value>
</var>
<!--<var>
<var-name>secondMark</var-name>
<var-value>totalMarks</var-value>
</var>-->
</field>
<!--<field property="totalMarks" depends="validatemarks"/>-->
</form>
