Chris,
I really appreciate your quick responses.
In the servlet it just calls some values through request.getParameter( )
and then it binds an array variable of a sychronized method that's all.
below is the whole filter class
public class UTF8Filter implements Filter{
public void destroy() {}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)throws IOException, ServletException{
request.setCharacterEncoding("UTF-8");
chain.doFilter(request, response);
}
public void init(FilterConfig filterConfig) throws ServletException {}
}
