最近在调试xwiki的时候遇到java.lang.IllegalStateException异常,在google上baidu了一把
经过分析查看jdk文档终于找到了解决方案,在response.sendRedirect("")方法后加return语句即可:
原因是在程序中两次调用response.sendRedirect("")方法

j2ee5.0中的介绍:

sendRedirect

void sendRedirect(java.lang.String location)
throws java.io.IOException
Sends a temporary redirect response to the client using the specified redirect location URL. This method can accept relative URLs; the servlet container must convert the relative URL to an absolute URL before sending the response to the client. If the location is relative without a leading '/' the container interprets it as relative to the current request URI. If the location is relative with a leading '/' the container interprets it as relative to the servlet container root.

If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.

 

Parameters:
location - the redirect location URL
Throws:
java.io.IOException - If an input or output exception occurs
java.lang.IllegalStateException - If the response was committed or if a partial URL is given and cannot be converted into a valid URL

IllegalComponentStateException
在不合理或不正确时间内唤醒一方法时出现的异常信息。换句话说,即 Java 环境或 Java 应用不满足请求操作。  回复  更多评论

在response.sendRedirect()方法后加return语句即可,如下:
response.sendRedirect("index.jsp");
return;

原因是:在程序中两次调用了response.sendRedirect()方法。

jdk5.0文档中很清楚地介绍了出现IllegalStateException异常的可能情况:

1)同一个页面中再次调用response.sendRedirect()方法。
2)提交的URL错误,即不是个有效的URL。

但是我整个文档里就没有那个response.sendRedirect()语句啊,也有这个异常啊,大侠给看看:
<%
String filename = "D:/Program Files/Genuitec/workspaces/zoology/WebRoot/jianfang.txt";
//if (request.getAttribute("url") != null) {
// filename = (String)request.getAttribute("url");
//}

System.out.print("filename "+filename);
response.setContentType("application/msword");
response.setHeader("Content-disposition", "inline; filename="
+ filename);
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
try {
bis = new BufferedInputStream(new FileInputStream(new File(filename)));
//getServletContext().getRealPath("" + filename)));
bos = new BufferedOutputStream(response.getOutputStream());
byte[] buff = new byte[2048];
char[] c =new char[2048];
int bytesRead;
while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
bos.write(buff, 0, bytesRead);
}

} catch (final IOException e) {
System.out.println("出现IOException." + e);
} finally {
if (bis != null)
bis.close();
if (bos != null)
bos.close();
}

现在关键的是,我的项目使用struts2写的,response.sendRedirect()都是在struts2框架里面定义了的,我怎么处理呢?  回复  更多评论
