Hi, François and Mark,
Actually, I think WO allows either the old NeXTStep defaults form:
-mainInstance YES
or the newer Java Properties form:
-DmainInstance=true
but I think you have to follow the conventions for either side all
the way through. That is, for the Java form:
* prefix the argument with "-D"
* separate the key from the value with "=" and no spaces
* use "true" or "false" for boolean values (I think the uppercase
equivalents are OK as well, but not sure)
and for the NeXT defaults form:
* prefix the argument with "-" (and no "D")
* separate the key from the value with one or more spaces
* use "YES" or "NO" for boolean values (I think the lowercase
equivalents are OK as well, but not sure)
In general, I think the Java Property form for arguments is safer
because the other form may be deprecated someday.
Technology migration sure can be confusing!
Regards,
Jerry

This seems very seductive, but when I configure my instance and
try to retreive the property ('String isMainInstance =
System.getProperty("mainInstance");' ) all I get is a NULL value...

You could add an argument into JavaMonitor for one instance but
not the others.
(-mainInstance TRUE)
Retrieve this property within your code with System.getProperty
("mainInstance")

Hi list,
I perform some maintenance operations at application startup by
catching the
WOApplication.ApplicationDidFinishLaunchingNotification
It works fine in testing, but in deployment mode the maintenance
code is called many times (once for each instance): this is
perfectly logical.
Is there a way to get the current instance number (to only
perform the maintenance in instance #1 ) ?
is there an other way to call this method one time, and one time
only ?
Thanks for your ideas!
Regards,
François
