Too Stupid To Run A Java Program (ewe)

Hello,
i have a simple problem but it makes me crazy

Initial situation:
I tried to run ""Cachewolf"/Cachewolf Downloadsite on the zaurus with pdaxrom.
Cachewolf is a geocaching application which runs under several OS (it runs without any problem under windows) because it's programmed with the plattform independent Java and Ewe.
The Ewe Environment exists for the zaurus, linux and java Runtime.

Some Java Runtime Environment exists on the pdaxrom Plattform:
- jamvm+classpath
- blackdown jdk

My Trial:
1. Download and install the jamvm 1.4.4 + classpath 0.92
2. Download the JRE Version of Cachewolf
3. Download the JRE Version of EWE
4. Extracting both
5. Define the Path to classpath and the ewe over the /etc/profile

6. The command tries to execute cachewolf:

6.1.

Error: java.lang.ClassNotFoundException: .mnt.car.cachewjar not found in java.lang.ClassLoader$1

6.2

The same Error as 6.1

6.3

Error: java.lang.Exception: Class not found: 12M at ewe.applet Ewe.main ....


I make several other trys with all possible combinations (Linux Cachewolf with JRE Ewe, Zaurus Cachewolf with JRE EWE, Zaurus Cachewolf with Zaurus Ewe, java (jar) Cachewolf with JRE ewe .......) but nothing works. Either the ewe classes are not found or the jamvm tells me that the main.java class of ewe cannot found

I'm very new in Running Java Programs on the Zaurus and i know that jamvm can't bind the ewe class but i don't know how to solve the Problem and what mistakes i made .
