flex+servlet简单实例
下面是flex的主要代码

在servlet里加了一个过滤器，在以POST提交时防止中文乱码，全部设置为UTF-8
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
// TODO Auto-generated method stub
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
chain.doFilter(request, response);
}
