Jikes: "-encoding" is unsupported

[Steve Cheng]

Dear all,

I get the follow error message when I am trying to use jikes to replace
javac in tomcat 5.1.

    [javac] use: jikes [options] [EMAIL PROTECTED] file.java...
    [javac] For more help, try -help or -version.
    [javac] Error: The option "-encoding" is unsupported in this build.

Could anyone give me some hints about it?
