Jre vs. java

Question

First - Thanks in advance for any responses!
I have a .jar file that runs fine like this...
java -jar client.jar (java 1.4)
But if I move the file to another platform - that has java 1.1.6, I can only use jre - and the following occurs,
jre -cp client.jar hostcl
Class not found: hostcl
The manifest is listed below:
Manifest-Version: 1.0
Main-Class: hostcl
Classpath: ./client.jar
The contents of the jar file:
Y:\ccm_wa\toolsdb\javainj~1\javainj>jar -tvf client.jar

2387 Wed Nov 06 10:30:14 EST 2002 untouched.class
9024 Wed Nov 06 10:30:14 EST 2002 utils.class
21980 Wed Nov 06 10:30:12 EST 2002 vars.class
Why does it work fine in 1.4, but not 1.1?
Mark.

Answer 1

Does class hostcl inherit from a class not available in 1.1.6? Invoking JRE 1.1.6 with the following class (compiled under 1.4) also returns the error you describe :
public class Test extends java.util.HashMap {
  public static void main(String args[]) {
    System.out.println("this is a test");
}The program runs as expected when not inheriting from HashMap.
