Wrong CAP file version error message

Question

I'm trying to write a loader application that will send a CAP file into JavaCard, and then install it automatically.
I have developed my JavaCard Applet by using Eclipse3.1.0 and JCOP30.
After running my JavaCard Applet by Eclipse, I got its CAP file in folder [b\bin\FVSCardPkg\javacard\[/b]
But when I run my loader application with this CAP file, the error message will display:
EX: msg Wrong CAP file version, class class com.ibm.jc.JCException
Wrong CAP file version
     at com.ibm.jc.CapFile.parseHeader(Unknown Source)
     at com.ibm.jc.CapFile.readCapFile(Unknown Source)
     at com.ibm.jc.CapFile.<init>(Unknown Source)
     at LoaderPkg.loader.load(loader.java:35)
     at LoaderPkg.loader.main(loader.java:20)
This is my loader application source code:
import java.io.*;
import com.ibm.jc.*;
import com.ibm.jc.terminal.*;

*  Sample loader. Demonstrates how to use the offcard API to download
*  a cap-file on a JCOP41V22 Engineering sample card and listing of applets loaded will

How to solve this problem?
Thank you in advance.

I'm not understanding if your cap file is in "b\bin\FVSCardPkg\javacard\", then why are you loading "D:/MyCardPkg.cap"?
The issue isn't with your off card application, but the cap file version. Look at the cap file components in JCVM specification. I believe it's the Header component. The major, minor should match your card but not greater. In other words, your can't load a 2.2 on a 2.1 card, but a 2.1 can load on a 2.2
