<s:submit value="Register"/>
</s:form>
struts.xml
<action name="insertdata" class="com.curd.action.InsertAction">
<result name="success">RegisterSuccessful.jsp</result>
<result name="error">NotRegister.jsp</result>
</action>
InsertAction.java(Action Class)

private String username,password,cpassword,emailid;
private int mobileno;
private Date dob;
DAO dao=new DAO();
public String execute(){
return "success";

Answer 1

Not indenting code and XML is a horrible idea; it's impossible to think about.
The error message:
SEVERE: Attribute "name" is required and must be specified for element type "param".
So. Do you have any <param> elements around line 30?
<param minLength="10"></param>
Oh look, there's no name attribute for that <param> element.
Also, your execute() method is suspicious, and it's not clear if you have public setters for your action properties.
