About War Files
You can deploy JSPs, servlets, and their associated supporting files as individual files or you can package them into a web archive (war) file. The war file format is the same as the Java archive (jar) file format. When you deploy a web application on Integration Server using a war file, Integration Server unpacks the contents of the war file the first time you invoke the web application.
You can use any compression tool to produce a war file. When you create the war file, be sure to retain the directory structure described in
The Integration Server Package Directory Structure.
