Dear All,

For the client GUI what approaches are people considering for informing the user in the case of:
- a lengthy RMI response (e.g. connecting to a server that doesn't exist) ?
- a 1/2 second wait for a booking to be made ?

Choices to notify a user of a 'pending transaction':
- Implement a status bar to show the progress: This does the job but a status bar is not asked for in the requirements and I don't think one is expected.
- Do nothing: This may result in marks lost. E.g. you press "Book" and although the push button was quick, it can take a few seconds before the update occurs. Also, if there is an RMI connection loss, it might take about 15 seconds before a warning appears of a connection loss. And when trying with Ubuntu, due to a Linux issue there has been an indefinite wait. Surely a user would want to be aware of this?
- It may also be the case that a client should not have to wait 15 seconds for a response, and perhaps certain sun.rmi Properties could be changed (although this is not recommended in certain previous versions of Java).

Many Thanks,
Ehsan

Well it does seem that this extra feature isn't required: Link

Hi Ehsan,

I didn't do anything special for the (rather exceptional) situations you described. These are things that can be taken care of in next releases of the application, but for now the CSRs will be happy to have a good functioning application.

Kind regards,
Roel
