Hi,
I tried whatever you said. I created a bean with getter,setter methods on
userName,password. And in the verification.jsp, I used useBean tag with
scope="session". How do i use this in another jsp page? again i have use
useBean tag with session scope or is there any other way. Some times i'm
getting ClassCastException.
Here are small code samples on each page:
/************* start *********************************/
which i'm using in verification.jsp:
<jsp:useBean id="userInfo" class="com.nalini.servlets.UserInfo"
scope="session" >
<jsp:setProperty name="userInfo" property="*" />
</jsp:useBean>
<% String user = userInfo.getUserName();
String password = userInfo.getPassword();
//do all data base checking. If correct information provided by
//the client then forward to generate.jsp otherwise go to error.jsp
%>
------------------------------------------------------------------------
Here is the code in generate.jsp:
<jsp:useBean id="userInfo" class="com.nalini.servlets.UserInfo"
scope="session" >
<jsp:setProperty name="userInfo" property="*" />
</jsp:useBean>
<% System.out.println(userInfo.getUserName()); %>
<%-- rest is HTML page --%>
<form name="myForm1"
action="../servlet/com.nalini.security.GenerateKeysServlet" method="GET">
Enter a name to Key Pair<input type="text" name="nameToPair" size="20">
Enter Public Key name:<input type="text" name="publicKeyName" size="20">
Enter Private Key name:<input type="text" name="privateKeyName" size="20">
<input type="submit" value="Generate Keys" name="genKeys">
</form>
---------------------------------------------------------------------
In the GenerateKeysServlet's doGet, I'm writing the following code:
String userName = request.getParameter("userName");
GenerateSecurity genSec = new GenerateSecurity(); //this is not a bean.
genSec.generatePublicAndPrivateKeys(userName,publicKeyName,privateKeyName);
/******************** end **********************************/
Hope you got my problem.
Janavee.
