Is JavaTM Web Start an application installer?
JavaTM Web Start is an application launcher for JavaTM 2 technology-based applications that are written to be Web-deployed. It launches only those applications written on the JavaTM 2 platform. JavaTM Web Start caches resources locally on the disk, but this is only one aspect of its technology. It also provides a secure execution environment and a virtually transparent updating facility for applications. The end user does not need to manually initiate a software update because the application is updated each time it is used.
