org.xml.sax.SAXParseException：文件过早结束，使用birt 2.3.2和firefox 15

我们正在使用Birt 2.3.2。 我们试图在Firefox15.0.1中打开我们的报告，我们得到了一个没有堆栈跟踪的异常“org.xml.sax.SAXParseException:Premature end of file”

我们试图调试它，发现firefox发送了错误的内容类型。当我使用TamperData插件修改请求头时，它起了作用

已发送的请求为

如果您是从servlet使用引擎，请确保在响应中设置了内容类型：

---

response.setContentType（“text/html”）

我相信这是一个众所周知的bug

请看评论6：

解决方法是注释掉webcontent/birt/ajax/lib/prototype.js的第668行和第669行

在注释这些行之前，Chrome将发送内容类型为“application/x-www-form-urlencoded，text/xml；charset=UTF-8”，这会导致异常

在注释掉这些行之后，Chrome将发送内容类型为“text/xml；charset=UTF-8”，就像其他性能良好的浏览器一样：）

不过，BIRT报告附带的prototype.js似乎很旧，因为这部分代码在4年前的1.5.0rc0版本中已经修改过
