我想創建一些簡單的GWT + GXT應用程序。爲什麼會出現GXT異常以及如何解決它？
- GWT是2.6.1
- GXT是3.1.0
我創建簡單的類 MySampleApplication.java：
public class MySampleApplication implements EntryPoint {
public void onModuleLoad() {
AlertMessageBox d = new AlertMessageBox("title", "message");
d.show();
}
}
和簡單聲明MySampleApplication.gwt.xml：
<inherits name='com.google.gwt.user.User'/>
<inherits name='com.sencha.gxt.ui.GXT'/>
<inherits name='com.google.gwt.user.theme.clean.Clean'/>
<stylesheet src="reset.css" />
<entry-point class='com.mySampleApplication.client.MySampleApplication'/>
看起來沒有什麼更容易，但它失敗：
onModuleLoad() threw an exception
Exception while loading module com.mySampleApplication.client.MySampleApplication.
See Development Mode for details.

刪除單元緩存和檢查，如果你有沒有舊GWT罐子你類路徑。檢查你的代碼。它運行。 – 2014-10-20 10:55:27
