cannot execute java.exe

I'm really having a hard time here. I have installed, uninstalled and installed again SDK1.3.1. I've updated my autoexec.bat to look as follows and I still get cannot execute c:\jdk13\bin\java.exe when trying to do the -version command. I'm running Windows ME. Any suggestions?

SET PROMPT=$p$g

SET TEMP=C:\WINDOWS\TEMP

SET TMP=C:\WINDOWS\TEMP

SET COMSPEC=C:\WINDOWS\COMMAND.COM

SET windir=C:\WINDOWS

SET winbootdir=C:\WINDOWS

SET PATH=C:\jdk13;C:\jdk13\bin;C:\jdk13\jre;C:\jdk13\lib;C:\jdk13\include;C:\WINDOWS;C:\WINDOWS\COMMAND;C:\PROGRA~1\DELL\RESOLU~1\COMMON\BIN

SET CLASSPATH=.;c:\jdk13\lib\tools.jar

Thanks,

Leeanne
