Hi All I have list of module object. I want to show it to user and user can edit it and can save it also. In module object three members are there 1 String moduleName 2.boolean readFlag 3. writFlag.

The bean i am using is in Request Scop i don't want to use any other scop. My problem is setterOfThatList is not called when update button is clicked. Where as on the same page i used another inputText, setter of the variable which is connected to this inputText is called.

Hi All
My Requirement is to make a form using rich faces 4.0 where user can enter his address details like Country, State , City

Now i want Once Country is selected state should be selected according to country
i want to display only 10 state at a time so using autocomplete component.
Now my problem is if i am selecting any state it is showing id instead name of state or country.
secondly i want to give ajax support so that as soon as a state is selected city should be populated accordingly
i am doing like this

Hi All
I am using JSF 2.0 , I have two beans UserBean ( Request Scope ) and UserInfoBean( Session Scope ).
I want to know how can initialize UserInfoBean from one method of UserBean( Request Scope ) so that i can access it from anywhere.

I also want to know performance wise which is better 1. Put a bean as session bean 2. put different different variable in session individually.
Thanks A Lot

You should not store client-specific state in instance variables of the service.
In your example, there is no reason for having two operations. Instead you should have only one that takes an User object as input and returns an User.
Do not use instance variables in the service!

If you must have a stateful web service, then you can have an operation that receives some data, stores it in a database and assigns an unique id to it.
The id is returned to the client and, when invoking subsequent operations on the service that requires access to the data, the client supplies the unique id.
This is, however, still a bad idea, since it will seriously complicate scaling of the service - it is all good and well if you run in one single instance of the service, but imagine the case when you have a layer 4 switch or similar in front of a cluster of servers, each running an instance of the service. In such a scenario, you do not want to use one single database to store all the data, since it will become the bottleneck of the system.
Stateless web services do not need to share any data and can thus be easily scaled.
Best wishes!

Thanks a lot IVAN
I made a web services in which i am not using any instance variable
there is a method which takes arguments and return some thing. It works fine till i return any primitive data type or array of primitive data type, but fails when i try to return my own Object or array of Object . If a am testing through web browser then i am getting correct output

1. service class
2. used class
3. service.aml
4 build.xml
5 test class
6 error
