在sturts action 中执行添加的方法 执行能成功 但是也要抱错！
this.getProductTypeActionnn().save(productType); //调用添加的方法
request.setAttribute("message", "添加成功");
request.getRequestDispatcher("/manager/findProductType.do").forward(request, response);
return mapping.findForward("ok");

[/Quote]信息太少，这是个Exception还是个Error，是在什么地方？

request.getRequestDispatcher("/manager/findProductType.do").forward(request, response); 楼主这句已经forward了，
流已经返回了，然后你又从mapping取流 return mapping.findForward("ok"); 显然是错误的状态啦
