Multiple ActionServers in java with the same action definition [closed]

edit

Hi all, I have to invoke multiple action servers with the same signature from a single java program. The program is simply a planner which generates a sequence of actions. Wthin the planner actions are simply represented by their names as a string. As we want to acheive that the invoking program does not have to know all the action servers in advance we like to distinguish the currently invoked action server by using action name. In C++ this is possible because the action server/client topics use a prefix. Is there a mechanism to achieve the same result also using ros java.

Thanks in advance.
