　　Env：
Application Server: Weblogic Portal 9.2.1
OS: Sun OS (Unix)
　　
Findings:
We use the commons-fileupload.jar v1.0 to upload file in the JSP. In the JSP, there include 5 Javascript files whose encode are all ANSI.
<script language="JavaScript" src="<%=request.getContextPath()%>/resources/js/jquery.js"></script>
…
After I taken all these js out from the JSP, the error didn’t happen.

And if we access the through web server, the error didn’t happen either, don’t know why.

Solutions:
　　
Option 1: Include the JS dynamic:
<script>
<%@ include file="/resources/js/jquery.js"%>
…
</script>

Option 2: Retrieve the js functions which are used by the JSP from the js file and write directly into the JSP:
<script type="text/javascript">
function A(){}
function B(){}
….
</script>

Option 3: Access through web server (Actually, in production, user must access through web server, but I think it’s a temporary solution).

Option 4: 

收获:
1.Developing environment initial set up, remember to set the text file encode to UTF-8 in IDE at the beginning of developing.
2.File encode, don’t quite understand it.
3.Javascript Object tech, when I try Option 1 and Option 2, I got JS error both, but I cannot manage to resolve it. There are more than 10000 lines in one of the JS file.
