Hi

Check your directory structure properly, and configuration of web.xml file.

Go through http://www.onjava.com/pub/a/onjava/2001/04/19/tomcat.html URL.

Otherwise run start your tomcat, and check document for deployment of web application.

Form bean values are populated as per request parameter values. If its textbox then its request parameter value is "". So its not a null value.

Verify that in validate method are you getting value of district? if yes then you are resetting your form values back or your ajax code might resetting the value of district in your form.

How do you pass the page no to servlet ? is it by passing as query string such as (something?next=2).

When you click on next button then are you submitting the page with incremented page no value as query string or make use of hidden parameter of the page?

Abhishek, How can session used to track the two different request from different machine ?

Kavitha, you have to persit(or cache) the information of pending request in server side on the basis of user, then you can track which is pending or in process request.

As per you error stack trace, you are not giving fully resolved name of your MyUtlilty class while compiling the code.

Or check path from where are you compiling code.

Specify your command to compile code.

Hi,
I am creating one application in which i dont want to use normal properties file for storing the configuration.

I want to put all my configuration in database and provide an API for fetching the configuration..

Can any one give me some path forward. How should i design my database and API..

Thanks,
Saumil



Welcome Saumil in Javaranch.


Property file contains key value pairs, the same way you can construct table such as cofing_property in which key and value(s) are columns. But if you would like to use properties as per user (or any other criteria) then you have to add one more column.

Regarding API, I will suggest you to have Helper class which is populate Hashtable or your favorite collection as per table values. And in Helper class you will have getter method to fetch value from collection.
