Description: Java library to reliably execute external processes from within the JVM
Executing external processes from Java is a well-known problem
area. It is inherently platform dependent and requires the developer
to know and test for platform specific behaviors, for example
using cmd.exe on Windows or limited buffer sizes causing deadlocks.
The JRE support for this is very limited, albeit better with the
new Java SE 1.5 ProcessBuilder class.
Reliably executing external processes can also require knowledge of
the environment variables before or after the command is executed. In
J2SE 1.1-1.4 there is no support for this, since the method,
System.getenv(), for retrieving environment variables is deprecated.
There are currently several different libraries that for their own
purposes have implemented frameworks around Runtime.exec() to handle
the various issues outlined above. The commons-exec package aims
at coordinating and learning from these initiatives to create and
maintain a simple, reusable and well-tested package.
