If you encounter an error when running a task, double check that you didn't make these common mistakes.
When you create a variable set used by a plan, it is easy to enter the wrong variable value. For example, you might incorrectly enter a cluster name instead of a domain name.
When entering port ranges in a variable set, check to make sure the ports are available on the target host or host sets.
The com.sun.sjsas81 namespace is invalid for user-supplied applications. When you enter a component directory for an application, make sure you change the namespace, as com.sun.sjsas81 is selected by default.
If you encounter errors when trying to install plug-in components, make sure the sourceImage variable points to a directory containing a valid install image of Sun Java Enterprise System Application Server.
