24 Aug Installation of packages on Integration Server through custom developed java program
Out of the box a package can be installed on webMethods Integration Server via the Administrator’s Package Management GUI or using WmDeployer.
Following code snippet with allow you to install packages on a webMethods Integration Server through the usage of a custom developed java program, leveraging the internal wM codebase for introducing a package.

Remarks:
- When compiling and running the java program make sure to include files wm-isclient.jar and mail.jar in your class path. File wm-isclient.jar can found in the “common/lib” folder of an Integration Server whereas file mail.jar is localized in the “ext” sub folder of the “common/lib” folder.
- Usage of the PackageInstaller program is PackageInstaller host:<hostname> port:<port> user:<username> pswd:<password> pckg:<package1>,<package2>,…
The .zip extension for package names should be omitted - At this moment the java program is working with at least webMethods Integration Server v7.1.2. Specifications contained herein are potentially subject to change so use them at your own risk.
