HttpSessionBindingListener Q

Hi Mat,

What you said only I thought, but after executing it in Tomcat I get the out like this BBUBBUBUB(bound bound unbound bound unbound unbound).

For the setAttribute in the api it is given as

If an object was already bound to this session of this name that implements HttpSessionBindingListener, its HttpSessionBindingListener.valueUnbound method is called.

If the value passed in is null, this has the same effect as calling removeAttribute().

Mat can you clear my doubts clearly. How the flow will be.

Thanks

HttpSessionBindingListener Q

Hi Kapil

Rancher's helped a lot things. I think answer given for mock question 55 is wrong. Actual output will be BBUBBUBUB, but in ans it is given as BBUBUB.

how we can arrive is

setAttribute with new Object ---> gives B
setAttribute with new Object ---> gives B
setAttribute ---> gives UB since object already bound to the session so valueUnbound will be called.
then it will call the value bound for
the new value ---> gives B
removeAttribute will call the valueUnbound so it
will print ---> UBUB

so the output will be BBUBBUBUB for clear picture i will put like this to avoid confusion -B--B--UB--B--UB--UB- (bound for "-B-" and for unbound "-UB-".

to get the output of the book answer we should remove one of setAttribute with new Object

please help me out if i have made any error

Thanks

Regarding TLD deployment

Hi

If I put the XML schema like this it works fine for me

<?xml version="1.0" encoding="ISO-8859-1" ?>
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
version="2.0">

but in HFSJ it is given as

<?xml version="1.0" encoding="ISO-8859-1" ?>
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-taglibrary_2_0.xsd"
version="2.0">

Can anybody explain what is the significance of both.

reg deployment descriptor

I have a doubt regarding this scenario

I have added the this tag in web.xml
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<el-ignored>true</el-ignored>
</jsp-property-group>
<jsp-config>

if you do so El should be disabled.

In the ROOT webapps i have the code like

<html>
<body>
<h1>Hello EL</h1>
${param.command}
</body>
</html>

if i try like this http://localhost/jspex/test5.jsp?command=Hi
