Hello,
I am facing with a very unusual problem, NullPointerException. The problem
is happening when SmartCard.start( ), is being called. I feel it is
happening when it is trying to �Configure the CardTerminal Registry�. In
the opencard.properties file I have specified,
#Configure the CardTerminal Registry:
OpenCard.terminals
=com.gemplus.opencard.terminal.GemplusCardTerminalFactory|mygcr|GCR410|COM1
I am using the reader provided by Gemplus, model type being GemPC410. The
Reader is connected to COM1 port only.
The stack trace is given below:
opencard.core.terminal.CardTerminalException: java.lang.NullPointerException
at
com.gemplus.opencard.terminal.GemplusCardTerminal.open(GemplusCardTerminal.j
ava, Compiled Code)
at
com.gemplus.opencard.terminal.GemplusCardTerminal.open(GemplusCardTerminal.j

at
opencard.core.terminal.CardTerminalRegistry.add(CardTerminalRegistry.java:13

at
com.gemplus.opencard.terminal.GemplusCardTerminalFactory.createCardTerminals
(GemplusCardTerminalFactory.java, Compiled Code)
at
opencard.core.service.SmartCard.handleTerminalFactoryEntries(SmartCard.java,
Compiled Code)

opencard.core.service.SmartCard.configureTerminalRegistry(SmartCard.java,
Compiled Code)
at opencard.core.service.SmartCard.start(SmartCard.java:527)
at ReadFile.main(ReadFile.java:14)
I have another doubt.
When SmartCard.start( ) is called, in what directories does the
OpenCardPropertyFileLoader.loadProperties( ) method, looks for
�opencard.properties� file? The book says it looks in,
[java.home]/lib/opencard.properties
[user.home]/.opencard.properties
[user.dir]/opencard.properties
[user.dir]/.opencard.properties
Can you explain the meaning of each statement?
Rgds,
Dharanendra S. Pandit
