Release 10.1A: OpenEdge Development:
Java Open Clients

Connection states

A connection between a Java Open Client and AppServer can be in one of three states that define the status of the current AppServer method call:

RUNNING — An AppServer method is executing. No other AppServer methods can be executed when the connection is in the RUNNING state.
STREAMING — There is at least one open output ResultSet. AppServer methods cannot be executed when the connection is in the STREAMING state. To determine whether a connection is in the STREAMING state, invoke the _isStreaming() method on any proxy object sharing the connection.
IDLE — The connection is not in a RUNNING or STREAMING state.
