Classpath optimization in a Java runtime environment

摘要

A computer implemented method, data processing system, and computer usable program are provided by the aspects of the present invention. Aspects of the present invention identify required classes of a software program in the import statements in the source code. Next, the aspects of the present invention identify an element in a classpath environment variable that contain only the required classes and generate a new classpath environment variable with the identified element. Aspects of the present invention then store the new classpath environment variable in a classpath file that is specific to the software program for subsequent invocation.

1. A method for classpath environmental variable optimization in a platform independent runtime environment, the method comprising the steps of:
a computer identifying a required class in an import statement in source code for a software program, wherein the required class is required by the software program; the computer identifying an element containing the required class in a classpath environment variable to form an identified element, wherein the element includes at least one of a directory and an archive file; the computer generating a new classpath environment variable using the identified element; the computer storing the new classpath environment variable in a classpath file, wherein the classpath file has a name of the software program and a classpath extension; responsive to a received command to invoke the software program, the computer determining if a classpath file with a name of the software program and a .classpath extension is present; and if the classpath file with a name of the software program and a .classpath extension is present, the computer invoking the software program using the classpath file having the new classpath environment variable stored therein.
