Using an imported class in a JSP file

Question

When you import a class you wrote into a JSP file, is there a way to submit values from forms to the entire class, or can you only use the methods within the class??

When you import a class you wrote into a JSP file, is
there a way to submit values from forms to the entire
class, or can you only use the methods within the
class??Yes, there is a way in JSP. You can use,
<jsp:useBean id="your_bean_id" scope="page or request etc" class="your_class">
<jsp:setProperty name="your_bean_id" property="*"/>
</jsp:useBean>
So, <jsp:setProperty> sets all the values inside your request object into the bean, if the class is having the properties (variables) with same name as of request object's parameters. You must have coded set method for all the properties whatever you want your jsp to set the values in the bean.
if your request is .../yourjsp?name=xxxx&age=25
then <jsp:setProperty> method will set the name and age inside bean if you have,
public class YourBean {
String name;
int age;
public void setName(String name) {
this.name=name;
public void setAge(int age) {
this.age=age;
Hope this helps.
