Jsp and database connection using bean

Question

* I want create a bean to handle database connectivity.The
          <jsp:usebean> tag uses
          no argument constructor ..so I cannot pass the userid and password to
          the constructor.
          So how can I create a database connection when the user_id and password
          will be a part of parameter ?
          * Now I'm opening database connection in the jsp scriplets. Everytime I
          refresh the
          jsp page a new connection is created ? Is it not going to choke the
          database ? I cannot use connection pool because every user logs in with
          different userid.
          Thanks
          

Answer 1

You can pass your arguments in this way:
          <jsp:usebean id="myBean" scope="page"/>
          <jsp:setProperty name="myBean" property="userId", value=<%= user_id%>/>
          <jsp:setProperty name="myBean" property="password", value=<%=
          user_password%>/>
          of course, in your bean class, you should create two setter methods,
          setUserId and setPassword.
          Hopefully, this will help you.
