NOT ONLY this my JQuery itself is not running...I was told to include the .js file using .When I did that it threw the exception... I included the jQuery-1.7.1.js file in my web-inf. 不仅如此，我的JQuery本身还没有运行...被告知要使用.js文件。当我这样做时，它引发了异常...我将jQuery-1.7.1.js文件包含在了我的web-inf中。

This is what i have done to include the file:- 这是我所做的包括文件的内容：

I copied the script code from jQuery website and created a new js file in Eclipse IDE. 我从jQuery网站复制了脚本代码，并在Eclipse IDE中创建了一个新的js文件。 Copied the entire script code in new js file and names it as jQuery-1.7.1.js.This is the file I am using for Jquery. 将整个脚本代码复制到新的js文件中，并将其命名为jQuery-1.7.1。这是我用于Jquery的文件。 Is there anything wrong here? 这里有什么问题吗？

Except jQuery-1.7.1.js I have no other js file related to JQuery. 除了jQuery-1.7.1.js，我没有其他与JQuery相关的js文件。

Please guide me... 请指导我...

Even though this is an older question, I thought I'd post my findings for those of us who happened upon this looking for an answer. 即使这是一个比较老的问题，我还是想将我的发现发布给那些正在寻找答案的人。

It appears that the <a4j:loadScript> element needs to be inside <f:view> . 看来<a4j:loadScript>元素需要在<f:view>内部。

if nothing else works you can use richfaces built in support for jquery without including the script 如果没有其他效果，则可以使用内置的支持jquery的richfaces而不包含脚本
