Why do we need Web Start?

Ans: Java Web Start is used to deploy standalone java applications over the network. When it comes to XI, the Integration Repository and Directory require specific Java client software, which is stored on the Integration Server and will be automatically installed on the client side using Java Web Start. This client software can be used during design time to develop new interfaces and mappings and to configure services, routings and mappings. As it allows applications to be started from the Internet using a web browser.
