Will the following paragraphs function well?
[1]
in a servlet:
SomeBean aBean = new SomeBean(......);
request.setAttribute("aBean", aBean);
aBean = null;
ServletContext sc = getServletContext();
RequestDispatcher rd = sc.getRequestDispatcher("someJsp.jsp");
rd.forward(request,response);
in "someJsp.jsp":
<jsp:useBean id="aBean" type="SomeBean" scope="request">
<%= aBean.getSomeProperty() %>
If right, then what on earth is the mechanism of parameter transferring?
Seems a new instance has been created when the object was transferred
from a servlet to a jsp file.
However, if my memory is right, the following codes did run wrong:
[2]
servlet side:
Connection aConn = ...;
Statement aStatement = aConn.createStatement();
ResultSet aResultSet = aStatement.executeQuery("...");
request.setAttribute("aResultSet", aResultSet);
aResultSet.close();
aResultSet = null;
aStatement.close();
aStatement = null;
aConn.close();
aConn = null;
jsp side:
<%= request.getAttribute("aResultSet") %>
What are the differences between the two paragraphs above?
(Hope I've asked clearly.)
