the tomcat encoding

[xu cheng]

hi all:
I wrote an app and there are some chinese content, and there are some code
like this

str = new String(chineseContentString.getBytes("iso-8859-1"), "utf-8");

the app runs pretty well in the tomcat of my pc. however ,when it was
deployed in other machine.
all the Chinese content becomes messy code.

so ,does anyone know how to got to encoding of the tomcat. or it was just
iso-8859-1 and cannot be changed?

thanks
by the way , the edition is 6.0.20
