Question

使用https://github.com/ArcBees/ArcBees-tools/blob/master/archetypes/gwtp-basic/README.md和http://c.gwt-examples.com/home/maven/ide-import/eclipse上的路线，我已经使用maven创建了一个GWTP项目。它在调试模式下运行良好，但我在部署它时遇到了问题。

运行命令mvn gwt：compile
将.war文件复制到两个不同的Tomcat服务器
重新启动服务器
浏览到该文件的位置，我收到404错误

我在catalina.out中收到以下错误：

信息： validateJarFile（/Library/Tomcat/webapps/test/WEB-INF/lib/gwt-user-2.5.1.jar） - jar没装。请参阅Servlet规范2.3，第9.7.2节。违规类：javax / servlet / Servlet.class

根据建议我从/WEB-INF/删除了gwt-user-2.5.1.jar，我收到以下错误：

当我尝试在本地Tomcat服务器和arixe.com服务器上部署此错误时，我遇到了同样的错误。

任何建议？

干杯

请勿在战争中使用gwt-user，而是使用gwt-servlet。修改您的pom并删除：

<dependency>
    <groupId>com.google.gwt</groupId>
    <artifactId>gwt-user</artifactId>
    <version>${gwt.version}</version>
</dependency>

替换为：

<dependency>
    <groupId>com.google.gwt</groupId>
    <artifactId>gwt-servlet</artifactId>
    <version>${gwt.version}</version>
</dependency>

部署gwtp hello world
