A Web application having a WAR format changes to an executable format, when you deploy it by using any of the following methods:

• Package the Web application in an EAR format and import the packaged application as a J2EE application in an archive format or J2EE application in an exploded archive format.
• Import a single Web application by specifying a WAR file or a WAR directory.

A single Web application that is imported is called a WAR application. For details on WAR applications, see 13.9 WAR applications in the uCosminexus Application Server Common Container Functionality Guide.

For details on the format of the executable J2EE applications, see 13.2 Format of executable J2EE applications in the uCosminexus Application Server Common Container Functionality Guide.

When deploy multiple Web applications is executed, isolated class loaders are created for each Web application. Consequently, even if classes with the same class name (Login servlet) are used in different Web applications, they are handled independently on separate class loaders.

Note that in the case of un-deploying a Web application deployed as the J2EE application, un-deploy process is performed for each J2EE application. You cannot un-deploy a Web application in each WAR.
