[izpack-users] How to modify userinputpanel according to anexecutable response

[macke]

Hi Klaus,

thx anyway for every help you give. I understand that with the db stuff, no
problem.
In the meantime I found my own solution for that. To incorporate with a DB
was not
the problem. I used the ProcessPanel for that and call an extra class for
this work 
(executeclass). The problem I had, was how to validate the whole userinput
for db 
communication I get by UserInputPanels before, to guarantee that everything
will work. 
My first solution in the moment was to extend the validation classes and to
assign beside
the ProcessingClient also the whole InstallData. A own validation class
called for example
by the last field of all of my UserInputPanels validates the variables set
in InstallData and 
for example tries to establish a db connection or validates if the db has
the right version
or whatever. To give better feedback in such cases, my extended validation
classes return
beside the boolean also a message. All in all not the best solution, but in
the moment
adequate for me.
Do you have experience with the ProcessPanel/ProcessPanelWorker and the
executeclass
ability? I wrote an generic class, which reads from a assigned file the sql
statements and
executes them. All in all I call this class by ProcessPanel.Spec.xml 13
times to executing state-
ments of 13 sql-Files. If one file causes an SQLException, in the moment the
next will still 
executed. In my blindness I don't know how I can stop all processes which
will follow 
if a sql exception will be thrown. How can I tell the ProcessPanel(Worker)
that a process
error occured and that all following processes should not executed?
  
thx for help from everyone in advance,
Macke

p.s.: izpack is great!
