Default bat file doesn't work

I have implemented a program and compiled all java files and tested the program and it works properly. After that I created a bat file and place it in the same map where I have the classes. But I receive this error message when I treid to start the program using the bat file:

C:\Documents and Settings\Ägaren\Mina dokument\maroun\mail_encryption\mailencryp
tion>java gui
Exception in thread "main" java.lang.NoClassDefFoundError: org/bouncycastle/util
/encoders/Base64
       at Kryptering.<init>(Kryptering.java:42)
        at gui.<init>(gui.java:26)
        at gui.main(gui.java:407)

I do not understand why it can not find org/bouncycastle/util
/encoders/Base64 when I try to start the program through bat file, but it works when run the program using JCreator.

Default

The most common cause of this on Windows is that there are normally two Java installs - a JDK one that can be used for software development and a JRE install that is used by default for Java program execution. It sounds like you have installed the provider in your JDK but not your JRE and the bat file is using the JRE.

Regards,

David
