我的数据库：mysql5.0,以及所有的JSP页面 都用“gbk”，我的上传代码：uploadFileServlet.java 代码如下，请问问题出在哪？怎么改？：

package pageconnection;

request.setCharacterEncoding("gbk");

ServletFileUpload upload = new ServletFileUpload(factory);


try

for(FileItem item:list){
if(item.isFormField()){
String name = item.getFieldName();

String value = item.getString();
// String str = new String(request.getParameter("title").getBytes("ISO-8859-1"),"UTF-8");

String value = item.getName();
System.out.println(value);

System.out.println(fileName);

byte[] buffer = new byte[4096];
int length = 0;
while((length = is.read(buffer))>0){
os.write(buffer,0,length);
}
os.close();
is.close();
}
}
}
catch(Exception e){
e.printStackTrace();
}


jdbc = new Jdbc() ;

}

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{
doPost(request, response) ;
}

}

楼主，你应该把jsp贴出来.

[鲜为人知]

看了一遍没有找到什么错误，应该是请求过程中出问题了

恩好的,每个JSP的页面 都是charset=gb2312或者gbk,数据库mysql的characterset=gbk;第二段代码是web.xml

jar 包冲突，看有没有重复的包，或者是与tomcat自带包版本冲突。
