How to insert data into mysql using jsf with all coding..
Thank you...
It is good practice to separate the presentation and data access aspects of your program.
This way, should you ever need to change the database implementation, you don't have to re-write all your presentation code as well.
Try http://download.oracle.com/javase/tutorial/jdbc/ to learn the basics of JDBC - you will need to use this to access the database.
I was asked to you how to insert data into mysql db using JSF three tier architecture... ???? ?
Plz if any one knw this ansr... then only reply me...
Thanks

No. YOU provide the code, with error messages, and we will help you. Nobody is going to do your work for you. Do some reading up on how to do this, there are thousands of web sites that show examples.Quote:

/// Main problem is i am not able to understand how to get values from jsf page and how to set values in to bean then insert the values...
Plz any one Give right solution ....
Thank you.....
You have to create a bean class and reference it in the faces-config.xml. Create the bean class (nothing special unless you are using some tag library).
Referencing it in the faces-config.xml is simple, just add a managed bean:
The MyBean is the Java class that holds the properties you want to be used.Code:<managed-bean>
<managed-bean-name>mybean</managed-bean-name>
<managed-bean-class>com.package.MyBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
If your class has a field 'apply_no' it will be populated when the bean is submitted. The values of this bean can then be used and accessed.Code:
<h:form id="myform">
<h:inputText value="#{mybean.apply_no}" />
<h:commandButton action="submit" value="Submit" />
</h:form>

How to give the limitation in dropdown ? when the our jsf page is runing.
Plz any one help me...
thanks
Sorry for getting back to you late on this, I have been away.
In order to regulate the options you need to do it on the back end (inside of the managed bean). What you would normally do is either set a class level variable that can be accessed on the page (via mybean.myvariable), or you add it to the request and access the values like that. Personally option 1 is probably the best way to go.
