I have observed that there are lot of users who asks questions on OTN and have problem in designing the custom generic exception handling framework. So in this and next some of the posts I will be describing how we can lay down a generic way to report custom exceptions to the page. These custom exceptions may be mostly for Business Specific errors for which we need to display a custom user friendly message on the page to the user.
In this post we will be seeing how we can customize the error on Model layer and take error messages from a resource bundle defined in the application.
Lets get started. We will first create a generic framework project where we will add exception handling related classes. We give it a name as FrameworkUtil. Framework util project will be dependent on model project from where custom Exceptions will be thrown in the enterprise applications.
First lets set up FrameworkUtil project - ADF Model Project
an ADF Model Project with below package structure. Added a resource
bundle ErrorBundle.properties which will be having all the Business
Errors which can be thrown from the applications model layer. These
errors will be in key value pairs in Error properties file. Read the complete article here.
