[OCF] Java Card Problem

[John Brookman]

Hi there! I am DESPREATE for some help... [just like most of us ;-)] (this problem has been bugging me for the past 1.5 months.) This message concerns a problem using: JDK, JRE and JC21 (all versions up-to date). I am able to do the following: - Run and Test (using the script files) the JC21 samples (< As described in the UserGuide) - Compile the NullApp.java to NullApp.class myself (this file is included in the samples-source directory) However, I am unable to actually USE the NullApp.class. [which I compiled myself] I removed the samples.jar file from the jcwde.bat command line and I inserted the location of the NullApp.class instead [and even tried to first put that NullApp.class in a .jar file and then try again with puttin the .jar file in the command line]. Unfortunately I receive the following error: --------------- I:\jc21\bin>java  -classpath I:\JDK\LIB;I:\JRE\LIB;I;i:\JC21\bin\jcwde.jar;i:\JC21\bin\NullApp.java;i:\JC 21\bin\api21.jar;i:\JC21\bin\NullApp.class;i:\JC21\bin\apduio.jar com.sun.javacard.jcwde.Main   JP.cfg [^^^ this is the command I use. JP.cfg is the correct file, containing the NULLAPP 'reference' ONLY!] JavaCard 2.1 Workstation Development Environment (version 0.4). jcwde is listening for T=0 Apdu's on TCP/IP port 9,025. java.lang.ClassNotFoundException: com.sun.javacard.NullApp.NullApp      [<<< Main ERROR, I guess...] jcwde terminating on receipt of SimulationException.  See previous messages for cause.

I receive NO errors when compiling the NullApp.java like this: javac -classpath %JC21_HOME%\bin\api21.jar NullApp.java [^^ Is this the correct way!?] To complete this message, I will include my settings: ----------------SETTINGS---------- REM ------- JAVA CARD (BEGIN) --------- SET JC21_HOME=i:\JC21 Set PATH=%PATH%;I:\JDK\BIN;I:\JDK;I:\JRE\BIN;I:\JC21\BIN;D:\PROGRA~1\BORLAND\DEL PHI4\BIN SET JAVA_HOME=I:\JDK set jc21bin=I:\jc21\bin set CLASSPATH=I:\JDK\LIB;I:\JRE\LIB REM -------  JAVA CARD(END)  --------- ----------------SETTINGS---------- Can you help me, please? Thank you in advance, John Brookman     P.S> If you think my settings, etc are correct, please respond as well...
