This is the FAQ page for GWT-OpenLayers.
Q. Why do I get this error:
com.google.gwt.core.client.JavaScriptException: (TypeError): $wnd.OpenLayers has no properties
A: At present, OpenLayers is not included in the GWT-OpenLayers module, so you have to make sure to include OpenLayers in your project. GWT-OpenLayes is compatible with OpenLayers 2.4 and up, but using OpenLayers 2.7 is adviced. There are at least two ways in which OpenLayers can be included in your GWT project.
- in the head tag of your application html
- in the GWT module xml
To include OpenLayers in the head tag of your application html do:
<html> <head> ... <script src="YOUR_PATH_HERE/OpenLayers.js" type="text/javascript"></script> </head> ... </html>
To include OpenLayers in your GWT module xml do:
<module> ... <script src="YOUR_PATH_HERE/OpenLayers.js"/> ... </module>
See also "Automatic resource inclusion" in the GWT documentation on how to link javascript files via the GWT module xml.
