Hi Zhang,
Looks like an entry is missing in your module.xml file. Download the Eclipse projects that I have posted and refer the module.xml files.

Any relation to the previous comment?

Hi abhijeet, i has follow you, but i still get the error .
In the last log of my GWT Development Shell, i found this :

[TRACE] Finding entry point classes
[ERROR] Unable to find type ‘com.maharana.client.HelloWorld’
[ERROR] Hint: Previous compiler errors may have made this type unavailable
[ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly
[ERROR] Failure to load module ‘com.maharana.HelloWorld’

is there anything solution to solve this problem that you know ?

this is my specification :
-eclipse 3.2
-GWT Windows 1.5
-gwtext-2.0.3.jar
-ext-2.0.2.jar
-java sdk 1.6
- RAM 512 MB

thanks in advance

Its difficult to tell from what you have posted above. Does the development shell indicate anything else?

Hi,
Try these:
1. Remove and add the JRE System Library to build path again
2. Increase the heap size in run dialog (parameters tab >> VM options: -Xmx512M)

Also, if you are on Windows, you may get a runtime error like this

[ERROR] Unable to load module entry point class com.maharana.client.HelloWorld (see associated exception for details)
com.google.gwt.core.client.JavaScriptException: JavaScript TypeError exception: '$wnd.Ext.Component' is null or not an object
	at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:481)
	at com.google.gwt.dev.shell.ModuleSpace.invokeNativeVoid(ModuleSpace.java:270)

This is IE specific and solution is to have script tags as and not as
