In initialing the OCF layer, I write the SmartCard.start(); as the first statement in the method, initOCF(). However, when this statement is executed, the java.lang.NullPointerException error obtained. Whatis the reason? And how about the solution? I am now using Gemplus GemXpresso RAD 211 Toolkit. In fact, I have tried to run the examples, Purse and PurseClient. The scenario is initOCF() is in PurseClient.java. And a main() in there. It will make an object of PurseClient and this object will call the method initOCF(). There are no problems. However, when I use another program, let say driver.java. to perform the similar task as PurseClient.java, I obtained the error above. Why? In fact, the code is copy from PurseClient.java, but the error is caught in the 1st sentence. It is really strange!!!
