You need to see the exact command that WinME could not interpret as a command or batch - therefore I suggest you.
1. make the first line of start.bat and catalina.bat = REM @echo off
2. in start.bat change the line:
call "%EXECUTABLE%" start %CMD_LINE_ARGS%
change start to ^ run so it will continue in the same window
Right off hand, I bet your path is not finding
Java correctly. What happens if you type: java -version
at the command line.
