problem with jsp:useBean

[Sai Narasimha Reddy]

I written a servlet, NewServlet with /NewServlet.do url-pattern for it.

In NewServlet I registered a Person object as follows

Person p = new Person();
p.setUsername("sai");
p.setPassword("xxx");
request.setAttribute("person",p);

then i forwarded the request to /index.jsp

Next, inside index.jsp i wrote this code

<jsp:useBean id="person" scope="session" class="demo.Person" type="demo.Person" >
<jsp:setProperty name="person" property="username" value="litele" />
</jsp:useBean>

Person name = ${sessionScope.person.username}


But the output is not "Person name=litele" it's like "Person name=".

I mean the object that is created is not under sessionScope....is there any thing wrong in my code??

I believe you are specifying a scope that does not contain the indicated (i.e. person) object, so a new demo.Person object is created. This object has no relation to the one in request scope, other than that they are of the same class.

Then why a new object is not being created??........If it was created, it should print "Person name=litele" right??

i think the object "person" of type "demo.Person" in request scope is found when jsp:useBean action is trying to locate......that's why the object is not created i think......

if this is the case........then what does "scope" attribute really mean......does it mean the scope of already existing object or the scope of the newly created objects should be in

Can you show us your Person class ?

request.setAttribute("person",p);

then i forwarded the request to /index.jsp

use session to set the value

Can you show me your total JSP code??

I think your code is right but the problem arrive where you print the name.i have run your code and it is running well.

Can any body say why it showing different results??

Hi sudhakar, may be the tomcat in Netbeans IDE is not configured properly........don't get into such details.......the Netbeans people have to worry about it. Not you!

enjoy jsp!
