  System.out.println ("code:" +charset); * * * Resolve Chinese garbled * 1) Change the character encoding (Server.xml-connector properties) in the Tomcat platform * and Tomcat is the common platform for all projects, so don't, try not to change * 2) back to Iso8859-1 code

    4 before getting the parameters set: by setting the character parameter in the Web.xml to Req.setcharacterencoding (CharSet);
    Read information processing Chinese garbled String name=req.getparameter ("name");
    String pwd=req.getparameter ("pwd");


System.out.println ("Name:" +name+ ", pwd:" +pwd);
System.out.println ("Code before-name:" +name+ ", pwd:" +pwd);
2) Anti-search Iso8859-1 code: Through string in the garbled solution//byte bs[]=name.getbytes ("Iso-8859-1");
Name=new String (BS, "Utf-8");
Byte bs2[]=pwd.getbytes ("Iso-8859-1");
Pwd=new String (BS2, "utf-8");
SYSTEM.OUT.PRINTLN ("Encoded after-name:" +name+ ", pwd:" +pwd);
    Note: This way for a lot of parameters, it is not appropriate to use the Resp.setcontenttype ("Text/html;charset=utf-8");/Set protocol: IE no problem, but some browsers are not compatible//reply to the client String str= "
