Re: Informix JDBC TYPE4 Drivers
Have you guys started the rmi-server to listen to that port
already? , What is your classpath actually?
>java.lang.NullPointerException
Exactly, the pointer for a connection can not contain null, since
an implicit exception is placed by the JVM, and you dont have
a handler for that., anyway, seems like no process is listen to
that port.
