The minimum system requirements and operating system requirements for the Java Class Adapter are detailed in the system requirements (www.ibm.com/software/integration/wdatastagetx/requirements/requirements.html). See also the release notes (www.ibm.com/support/docview.wss?rs=2320&uid=swg27008337). It is assumed that a Command Server has already been installed on the computer where the adapter is to be installed for runtime purposes.
