Hi,
what if an SQLException occurrs on the server?
in MyServiceImpl.java:
public boolean saveRecord (Record rec) // throws Exception
{
try
{
dbs.saveUser (usr);
}
catch (SQLException e)
{
// create MyException and throw it?
}
return (true);
}
Should I define an own Exception type or can I pass SQLException over
RPC somehow?
Thanks
Magnus
