Although installation of any version of the WebSphere® test environment is optional,
remote deployment to all versions of WebSphere servers are supported.
For every version of the WebSphere runtime environment, a stub
directory exists, for example x:\runtimes\base_v6_stub,
where x is the installation directory where this product
is installed. These stub directories contain WebSphere Application Server JAR files
for compile-time support, WebSphere Application Server configurations for
remote deployment and the corresponding Java™ Development Kit (JDK). These stub directories
are only used when the corresponding test environment version is not installed.
