Hello,
I’ve a problem with Tomcat 3.1 and JSP Beans.
The following code doesn’t work in Tomcat 3.1 but works in Suns JSP
severs 1.0
Code :
****************************************************
<html>
<jsp:useBean id="DLoginData" scope="session" class="Login.DLoginData"
type="Login.DLoginData" />
<body>
Hello <jsp:getProperty name="DLoginData" property="UserName"/>
</body>
</html>
****************************************************
Tomcat bring this error message :
Included servlet error: 500
Location: /SMD/servlet/SMDMain
Internal Servlet Error:

'UserName' in a bean of type 'Login.DLoginData'

But this works :
****************************************************
<html>
<jsp:useBean id="DLoginData" scope="session" class="Login.DLoginData"
type="Login.DLoginData" />
<body>
<%
out.print ("Hello " + DLoginData.getUserName() + " !");
%>>
</body>
</html>
****************************************************
What’s wrong with the first version ? I’ve put the class
Login.DloginData in my servlet to the session. All classes a at
D:\Dev\SMD\WEB-INF\classes.
Can someone help me please ? Is the bug befor or behind the monitor ?
Stefan
