Try putting the call to getJavaValue() (in the html) after you include the nocache.js file.

I'm trying to call a Java method form a part of Javascript code. I've read Accessing Java Methods and Fields from JavaScript and I think I've reproduced something equivalent but it does not work. Here is my HTML page : <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http:// www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <script type="text/javascript" language="javascript"> var abcd = getJavaValue(); </script> <script type="text/javascript" language="javascript" src="com.eloquant.test.test.nocache.js"></script> </head> <body> </body> </html> Here is the java code : package com.eloquant.test.client; import com.google.gwt.core.client.EntryPoint; import com.google.gwt.user.client.ui.HTML; import com.google.gwt.user.client.ui.RootPanel; public class Test implements EntryPoint { public void onModuleLoad() { exportStaticMethod(); RootPanel.get().add(new HTML ("abcd =" + getAbcd())); } public static int getValue() { return 1; }; public static native void exportStaticMethod() /*-{ $wnd.getJavaValue = @com.eloquant.test.client.Test::getValue(); }-*/; public native int getAbcd () /*-{ return $wnd.abcd; }-*/; } When I run the app I get the following error : com.google.gwt.dev.shell.HostedModeException: Expected primitive type int; actual value was undefined at com.google.gwt.dev.shell.JsValueGlue.get(JsValueGlue.java:51) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeInt(ModuleSpace.java: 193)... If I replace in the HTML var abcd = getJavaValue(); By var abcd = 5; I've got a correct display, so Java calling Javascript is Ok, but I don't understand what's wrong with javascript calling java. Does any one have some ideas ?
