Can not work under ext4

[zhonghuafy]

I download Exporter and import into my project, but it seems that it can not work. I got errors below: Uncaught TypeError: Object #<Object> has no method 'reg' Exporter-all.js:204 Uncaught TypeError: Cannot call method 'substring' of undefined ext-all.js:15

the jsp page:

<script type="text/javascript" src="ext/ext-all.js"></script>
<script type="text/javascript" src="exporter/Exporter-all.js"></script>

the js: tbar: [{ xtype:'exportbutton', store: userStore },{ ... What should I do? Thanks for your kindness and waiting your help.
