smartcard access from jython

Hi All,

This is quite specific but I hope someone can help me..
I'm using a Sclumberger smartcard with their java libraries
to communicate with the card. Everything works fine(listing
connected cards, connecting etc.) through Jython. One thing
gives me a runtime error, one is suppose to implement the
slb.iop.IOPListener interface to catch events like
card/reader removed/inserted. Here is the implementation.

#######
class SymSIOP(slb.iop.IOPListener):
        def CardRemoved(event):
        #       iopCard = slb.iop.SmartCard()
#               print "card removed"
                pass
        def CardInserted(event):
                #print "card inserted"
                pass
        def ReaderRemoved(event):
                #print "reader removed"
                pass
        def ReaderInserted(event):
                #print "reader inserted"
                pass

Now, Initializing it like from another class:
        self.sIOP = slb.iop.IOP()
        lSymSIOP = SymSIOP();
        self.sIOP.addIOPListener(lSymSIOP);

In Java the class will look something like this(from their
example):

########
class SymSIOP implements slb.iop.IOPListener    {
                public void CardRemoved(slb.iop.IOPEvent event)         {
      //disconnect from card
                        }

                public void CardInserted(slb.iop.IOPEvent event)                
{
                  //Add card insert code here
                }

                public void ReaderRemoved(slb.iop.IOPEvent event)               
{
                  //Add reader removed code here
                }

                public void ReaderInserted(slb.iop.IOPEvent event)              
{
                  //Add reader insert code here
                }
        }


Now running it through jython, it runs fine but when I
remove the card and insert it again(always on the 2nd
action), I get a error from windows(popup): 'java.exe has
generated errors and will be closed by Windows. You will
need to restart the program. An error log is being created'
I would think it is the implementation of the interface,
maybe the event datatype that is not right. Also where does
windows log these errors..

Thanks for the help!!!

Regards,
Eugene.
