Constructor Detail

ActivationGroupDesc.CommandEnvironment

public ActivationGroupDesc.CommandEnvironment(String cmdpath,

Create a CommandEnvironment with all the necessary information.

Parameters:

cmdpath - the name of the java executable, including the full path, or null, meaning "use rmid's default". The named program must be able to accept multiple -Dpropname=value options (as documented for the "java" tool)

argv - extra options which will be used in creating the ActivationGroup. Null has the same effect as an empty list.

Since:
