Question

I need to build a GWT application that will be called by an external application with specific URL parameters.

For example:

http://www.somehost.com/com.app.client.Order.html?orderId=99999.

How do I capture the orderId parameter inside the GWT application?

Answer 1

Try,

String value = com.google.gwt.user.client.Window.Location.getParameter('orderId'); // parse the value to int 

P.S. GWT can invoke native javascript which means if javascript can do the stuff, GWT can do it too; e.g. in GWT, you can write

public static native void alert(String msg) /*-{  $wnd.alert('Hey I am javascript'); }-*/; 

In this case, you can even use existing javascript lib to extract param’s value in the querystring.
