Question

将GWT2.0更新为GWT2.4后，eclipse在使用ant构建GWT应用程序时显示错误消息。这是消息：

[java] Compiling module com.certus.noc.noc

和gwt.xml文件中的inherites模块

<inherits name='com.google.gwt.user.User'/>
<inherits name='com.extjs.gxt.ui.GXT'/>
<inherits name='com.extjs.gxt.desktop.WebDesktop' />
<inherits name='com.certus.noc.resources.Resources' />
<!-- Inherit the default GWT style sheet.  You can change       -->
<!-- the theme of your GWT application by uncommenting          -->
<!-- any one of the following lines.                            -->
<inherits name='com.certus.noc.resources.Resources' />
<inherits name='com.google.gwt.user.theme.standard.Standard'/>
<!-- <inherits name='com.google.gwt.user.theme.chrome.Chrome'/> -->
<!-- <inherits name='com.google.gwt.user.theme.dark.Dark'/>     -->

<!-- Other module inherits                                      -->
<inherits name='com.extjs.gxt.themes.Themes' />

<inherits name='com.google.gwt.i18n.I18N' />
<inherits name='com.extjs.gxt.charts.Chart' />

提前感谢您的回答

Answer 1

尝试添加

<inherits name="com.google.web.bindery.event.Event"/>

到你的主<project>.gwt.xml它应该解决事件问题还要尝试将gwt jar放在类路径中的gxt jar之前

并检查HasDirectionalSafeHtml从HasSafeHtml获取SafeHtml和gwt-servlet-2.4.0.jar，或检查您的类路径中是否存在gwt-servlet-2.4.0.jar的事件。

这应解决HasDirectionalSafeHtml个问题

Answer 2

我已经解决了这个问题。

删除WEB-INF / lib中的所有jar，然后从APP Engine和其他

复制新jar

有用的。然后它工作
