This step-by-step guide shows how to perform the migration of Nexaweb application to Nexaweb launcher

Prerequisites:

1. Nexaweb platform with version 4.5.66 or greater
2. NexawebLauncher Installer 

Step-by-step guide

To deploy a Nexaweb application using Nexaweb Launcher, the recommended approach is using Nexaweb Standalone Client, here are the steps:

1. Create  run.nexaweb file for launching  nexaweb web application.
   

   The way to nexaweb web application is by using a  run.nexaweb ( nexaweb Launching Protocol) file deployed on the server, when user type the url of a nexaweb file in the browser, the Windows will detect that the response is nexaweb file and it will launch Nexaweb  launcher to load the Web Start application according to the setting in the nexaweb file. So a nexaweb file needs to be created for the Nexaweb application.

   1. Download the latest version nexaweb platform( greater than 4.5.65.0009) and installed it on the Server
   2. Create a new Nexaweb application project with the 4.5.65.0999 or the later version platform
   3. copy NexawebImages.jar,  NexawebStandaloneClient.jar,  and all other jars to WebContent directory as below:
