Java is a general-purpose, object-oriented language which is designed to have few platform dependencies. Both the runtime environment and development tools are installed on SHARCNET clusters. The purpose of this article is to assist the user in deploying, executing, and trouble shooting Java programs on SHARCNET.
There are a number of ways that your program might be deployed onto a SHARCNET cluster: pre-installed software, as a RPM file, as a JAR file, or from source. Supported software, found [here], has an staff member assigned to support it and does not require deployment. An RPM package, typically available with a complete software platform, will have the steps prepared and typically involve more than just the Java environment. The remainder of this article will deal with the last two options, installing from java ARchive (JAR) files or directly from source.
A JAR file may be an "executable JAR file" which allow you to execute the program directly from the JAR file.
