How to use FileAccessService in SmartCard

hi friend,

thanks for reply.

I got the access of card file now.

Now i have another pblm, that i when i am using MFCFileAccess.getRoot() , it returns :3f00. When i try to assign this value into CardFilePath object it returns a NullPointerException.

My code is here,

MFCFileSystem fileSys = new MFCFileSystem();

MFCFileAccess fileAccess = new MFCFileAccess();

//System.out.println("File Root = " + fileAccess.exists(rootPath));

System.out.println("File Root = " + fileAccess.getRoot());

CardFilePath rootPath = (CardFilePath)fileAccess.getRoot();

MFCFileInfo fileInfo = fileAccess.selectFile(rootPath);

System.out.println("File Size = " + fileInfo.getLength());

System.out.println("File Header = " + fileInfo.getHeader());

when i run this code i am getting,

Got terminal: OMNIKEY AG Smart Card Reader USB 0

Herererere

File Root = :3f00

java.lang.NullPointerException
