How to use not filter

1. How to use Not Filter
12-12-2014

2. Abstract
• The main motto of this PPT is How to use Not
Filter in our applications.

3. Introduction
• Mule bundles more than a dozen Filters that
determine whether a message can proceed
through an application flow. The simplest
filters implement basic logic operators (such
as and, or, and not), but these simple
elements can be combined in various ways to
specify complex logical conditions.

4. Example

5. .mflow

7. • Flow of execution:
1. URL to trigger the service from browser
http://localhost:8091/NotFilter
2. NOT filter checks whether the request
contains ‘soft’ or not?, if no, it will print a
message ‘Success’, else it will not go further.
