Error on SapUP : received wrong reply handle from UaServer

I'm upgrading from ECC 5.0 (windows 2003 SP1 w/Oracle 10.2.0.2 no unicode) to ECC 6.0 (unicode).

I get DVD SAP_ERP_6.0_SR3_Upgrade_Master, when I execute prepare.bat and choose SERVER option :

--- prepare

Select operation mode:

- "EXIT"

- "SERVER"

- "SCROLL"

Enter one of these options [EXIT] := SERVER

Waiting for SAP Upgrade Assistant Server (UaServer) to connect at port number 4240 (CTRL-C to interrupt) ...

then :

---Starting Upgrade Assistant Server

Z:\usr\sap\put\bin>java -cp z:\usr\sap\put\UA\ua.jar UaServer

UaServer> Stable storage file 'z:\usr\sap\put\ua\UaState' not found

This error is produced when :

http://<hostname>:4240 or java -cp z:/usr/sap/put/uagui.jar UaGui

The error message is :

Waiting for SAP Upgrade Assistant Server (UaServer) to connect at port number 4240 (CTRL-C to interrupt) ..

Upgrade assistant server connected

SEVERE ERROR: received wrong reply handle from UaServer

I'm using this Java :

Z:\usr\sap\put\bin>java -fullversion

java full version "1.4.2_12-b03"

Can you help me?

thanks in advance

Fernando
