BodyContent.getReader() can't read SJIS code correctly

Question

          I have the JSP file
          <%@ page contentType= "text/html;charset=SJIS" errorPage="error.jsp"%>
          <vcsql:escapesql>SJIS Characters Here</vcsql:escapesql>
          and in the escapesql tag's doAfterBody method,
          I use "bodyContent.getReader()" to read the characters
          and write it to JspWriter. This is fine in WL6.0SP2,
          but I got ??? in WL6.1. And it seems OK when I print
          some Japanese Characters directly using JspWriter.
          public int doAfterBody() throws JspException
          try
          JspWriter out = bodyContent.getEnclosingWriter();
          Reader reader = bodyContent.getReader();
          int ch = reader.read();
          while(true)
          if (ch == -1)
          break;
          else if (ch == '\'')
          out.print("''");
          else
          out.print((char)ch);
          ch = reader.read();
          reader.close();
          }catch (IOException ex)
          return SKIP_BODY;
          Can anyone help me? I guess it is a bug of WL6.1
          Thanks.

You can't in JSP.
Java runs on the Server. You only have access to the server file system.
You do NOT have access to the client file system. And a good thing too.
Being able to load/edit/delete any file you want to from the client would be a huge security hole.
Just by browsing your website you pick up a file from my computer? I don't think so mate.
If you want the client to send a file, you have to use the standard html component for sending files: <input type="file">
In other words the user has to explicitly choose the file they wish to send to your server.
Your servlet then has to read that file from the request.
There are a couple of components around that help you with that. Check out the [url http://jakarta.apache.org/commons/fileupload/]jakarta commons File upload component.
