Update Facility Overview isCOBOL implements a software update feature that allows to download updates through the HTTP and HTTPS protocols. It's a general purpose updater that can be used to download any type of file, not only COBOL programs. The update process The isupdater tool connects to a given HTTP server and checks if a new version of the files is available. In such case, it downloads the files. The HTTP server (server side) and isupdater (client side) are configured through property files. Files are stored in ZIP archives on the server and are automatically unzipped once downloaded to the client. isCOBOL Server as HTTP server The isCOBOL Server can work as HTTP server for isupdater. Thanks to this feature, you're not forced to set up a HTTP server in order to take advantage of the software update feature. Post update operations At the end of the update process, isupdater can automatically run a program that takes care of post update operations such as copying the downloaded files in the proper folder. This program can be a standard COBOL program or a Java class runnable from the command line (e.g. a Java class with a main() method). Post update launch Isupdater can automatically run a given class at the end of the update process. This class must be reachable in the Classpath.
