you can see that I have a reference to a css file in the gwt.xml. From what I observe, that style will get put into the nocache.js and load it when my application start.

Right now, I don't want the reference to be the gwt.xml, Because URL of the CSS file is change dynamicly. I am wondering is it posible that I can inject this CSS during

run time and also the nocache.js?

If the URL of the stylesheet can change dynamically and (more importantly) independently of the GWT application, you have two solutions:

• load it independently from the GWT app (add a <link rel="stylesheet" href="..."> to the HTML host page)
• load it from the GWT app's EntryPoint, getting the URL by other means (extracted from the HTML host page –as a JS global variable, or some attribute value on an element–, or GWT-RPC, or whatever) and dynamically creating the <link> element from code (com.google.gwt.dom.client.Document.get().createLinkElement(), etc.)
