Posted by: wmgreat Posted on: 2003-04-01 19:46 我在servlet中跳转到一个另外一个servlet，语法如下： response.sendRedirect(request.getContextPath()+"/getsinglecontentinfo?processid="+processid+"&content="+content); 但是始终只有一个参数(content)能被传递到下一个serlvert。不知道是什么原因

Please post the code and the test data. Maybe the value of the processid is null? Try to add another parameter and see if you can retrieve it.

One thing you should always do is to encode the parameter values:
response.sendRedirect(request.getContextPath()+"/getsinglecontentinfo?processid="+URLEncoder.encode(processid)+"&content="+URLEncoder.encode(content));

The above code is for JDK 1.2 or 1.3. In JDK 1.4, you need to use Encoder.encode(string, charset);
