如何在Vaadin 6.8上加载外部javascript文件？

Question

I am using Vaadin 6.8 and need to load external javascript resource, but Vaadin of version 6.8 does not support @JavaScript annotation.

I have also tried Vaadin's CustomLayout, it loads html page, but does not execute javascript in that html under <script> tag?

Any other solutions on Vaadin 6.8?

Override method called writeAjaxPageHtmlHeader in your servlet class. You can there add any html to the head part of the "host page". See AbstractApplicationServlet for other extension points if you want to add it to for example body part.
