Here I am explaining client side validation in struts using validation.xml.
LoginForm
package com.clientsidevalidation;
import org.apache.struts.validator.ValidatorForm;
/**

*/
public class Loginform extends ValidatorForm{
String name;
String password;
String newLocale;
String Action;
public String getAction() {
return Action;
}
public void setAction(String action) {
Action = action;
}
public String getNewLocale() {
return newLocale;
}
public void setNewLocale(String newLocale) {
this.newLocale = newLocale;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
LoginAction
package com.clientsidevalidation;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**

*/
public class Loginaction extends Action{
public ActionForward execute(ActionMapping map,ActionForm form,HttpServletRequest req,HttpServletResponse res)throws Exception
{
return map.findForward("success");
}
}
ApplicationResources.properties
Loginform.name=Name
Loginform.password=Password
