I need to parse GET parameter
Will
user wants a different urls for the page. It would be very easy to use
parameters of GET request like xxxx.jsp?id=111111 to generate urls.
But how can GWT parse the GET request parameters?
or how to solve this kind of problem?

Look into History and HistoryListener. When your page is loaded, any history
token after a # will be automatically handed to your app. So your URLs will
look like xxxx.html#1, xxxx.html#2, etc.

If you host your GWT module in a JSP page, you can use normal JSP code
to grab the parameter -- request.getParameter("foo"). This mainly
works well for initial or startup parameters.
You can then stick the parameter into a JavaScript structure and
access the structure through the GWT Dictionary class. You could
generically add them all in a loop, too.
Example JSP code:
<body>
<%
String foo = request.getParameter("foo");
if (foo == null || foo.trim().length() == 0) {
foo = "default";
}
%>
<script language="javascript">
var parameters = {
foo: "<%=foo%>"
};
</script>
<script language="javascript" src="my.gwt.Module.nocache.js"></
script>
</body>
Example Java code:
Dictionary parameters = Dictionary.getDictionary("parameters");
String foo = parameters.get("foo");

I used native javascript to get the params:
private native String getParamString() /*-{
return $wnd.location.search;
}-*/;
Then you can call it by:
String getStr = getParamString();
// now you can parse this string into it's key/value pairs by splitting the string by ampersands then by equal signs.
Hope this helps.
