Jaroslav,
it's not obvious which line of your code causes the ClassCastException.
Could you do the following:
1. Point out which line causes the exception.
2. Add, just before that line, a statement that will print to stderr
the class name, like this:
System.err.println (request.getSession().getAttribute
(WebServer.SERVICE_MANAGER).getClass ());
ServiceManager srvMng =
(ServiceManager)request.getSession().getAttribute
(WebServer.SERVICE_MANAGER);
System.err.println (request.getSession().getAttribute
(WebServer.LOGGER).getClass ());
Logger logger = (Logger)request.getSession().getAttribute
(WebServer.LOGGER);
try {
System.err.println (srvMng.lookup (MachineManager.ROLE).getClass
());
MachineManager mngr = (MachineManager)srvMng.lookup
(MachineManager.ROLE);
request.getSession().setAttribute("machines",mngr.getRegistere
dMachines
());
} catch (ServiceException e) {
e.printStackTrace();
}
response.sendRedirect("/vend/jsp/machine.jsp");
Run the program and tell us what the output is. You can have some
classloader issues in the servlet container.
