Remarks

Execution of the Procedure

You have the ability to run (or not) the next procedure by adding a header. To do so, <Procedure Execution> must be initialized to True.

If <Procedure execution> is initialized to True:

J2EERun (or J2EERunXML) returns True if the link with the server has been established, False otherwise.
If the connection with the server was established and if the server fulfills the conditions requested by the header, the procedure is run.
If the procedure was run, J2EEGetResult returns:
- the result of the procedure if the procedure was successfully run,
- an empty string ("") if the procedure failed.
If the procedure failed or if it was not run, J2EEError returns:
- the "MustUnderstand" error code if the server does not fulfill the conditions requested by the header,
- an error in the other cases.
