Java Compilation error

[Chandhrasekar Saravanan]

Hi ,
I am using Insignia Jeode JVM to run my java application. Jeode Jvm is compatible with jdk1.1.
In my application I am using java.net.Authenticator class, which is availaible only in jdk1.2.
I have compiled in my Linux machine using
javac -target BasicReader.java
and this works fine in the linux machine which has jdk1.4 in it.
But when i transfer the .class file to Jeode and when i try to run the evm BasicReader i am getting the following error.
Exception in thread "main", java.lang.NoClassDefFoundError: java/net/Authenticator at BasicReader.main(bytecode 0)
could you please explain me why this happens and how to rectify it.

The jvm with support for java 1.1 has no knowledge of the bytecode compiled on your linux machine which included stuff in java 1.2. I would suggest upgrading your jvm on the target machine.
