If you want to place individual values in the session scope, you have to
use scriptlets, e.g.:
<%
session.setAttribute("myTextField", request.getParameter("myTextField");
%>
assuming the text field in the form has the name attribute set to myTextField.
Same thing for an array:
<%
session.setAttribute("myCheckBoxes",
request.getParameterValues("myCheckBoxes");
String[] myArr = new String[2];
myArr[0] = "foo";
myArr[1] = "bar";
session.setAttribute("myArr", myArr);
%>
Code like this in a page can easily create debugging and maintenance problems,
so I suggest that you instead create a bean with the appropriate properties:
package com.mycomp.foo;
public class MyBean {
private String myTextField;
private String[] myCheckBoxes;
public String getMyTextField() {
return myTextField;
}
public void setMyTextField(String value) {
myTextField = value;
}
public String[] getMyCheckBoxes() {
return myCheckBoxes;
}
public void setMyCheckBoxes(String[] value) {
myCheckBoxes = value;
}
}
and then use <jsp:useBean> to create an instance of the bean in the session
scope and set all its properties to the submitted form values:
<jsp:useBean id="myBean" scope="session" class="com.mycomp.foo.MyBean">
<jsp:setProperty name="myBean" property="*" />
</jsp:useBean>
See the JSP 1.1 spec for details about all of the above.
