how to get the values in a servlet? the values are set in a bean using jsp

<jsp:useBean id="bean" class="com.hrms.servlet.UserBean" scope="session" >
<jsp:setProperty name="bean" property="username" param="textfield1" />
<jsp:setProperty name="bean" property="password" param="textfield2" />
</jsp:useBean>

what should i write in servlet to retrieve those values?

What is the relationship of the servlet to the JSP?

Assuming that the servlet is submitted to by the HTML page generated from the JSP, then the only way to send data to the servlet over HTTP is as request parameters; either in the query string or as form elements.

Or, take the direct (server-only) approach and place the values in the session for later retrieval.

yes. the jsp is submitted to a servlet.

i did not understand completely.

my assumption is if i set some properties in a bean (from jsp) those values i can retrieve in the servlet from that bean. but how? i dont know how to write the code.
or is my assumption is wrong?

I'm not clear on why you'd want to instantiate a bean in a JSP, set its values, then retrieve it in the servlet.

Why not just create the bean in the servlet that displays the original JSP? Or if you *are* submitting a form, put the values into the form.

Please correct me if I have not understood your problem. You want to access 'bean' in your servlet. Isn't 'bean' set as a session attribute when you specify

<jsp:useBean id="bean" class="com.hrms.servlet.UserBean" scope="session" >

I think you can directly access this attribute using getAttribute() method.

i think you can make object of bean class in servlet and by properly casting you can get all the values in servelt
