我刚刚基于 activeweb -simple示例启动了一个新的 ActiveWeb/ActiveJDBC 项目。当我按照自述文件中的描述使用 Jetty 构建和运行它时，一切正常，但我无法让它与 TomEE plus (7.0.2/1.7.5) 一起使用，我想寻求帮助。
我尝试了几件事，所以我将把它分成三个部分。
1) 不在 Jetty 上运行，JSR-356 支持不可用
在构建和部署战争时，无论我将战争文件复制到 webapps 文件夹还是使用 tomee-maven-plugin，都会发生错误：
FATAL: Error during ServletContainerInitializer processing
javax.servlet.ServletException: Not running on Jetty, JSR-356 support unavailable

tomee-maven-plugin 定义如下：
<plugin>
<groupId>org.apache.openejb.maven</groupId>
<artifactId>tomee-maven-plugin</artifactId>
<version>1.7.5</version>
<configuration>
<tomeeClassifier>plus</tomeeClassifier>
<systemVariables>
<activejdbc.log />
<active_reload>true</active_reload>
<activeweb.log.request>true</activeweb.log.request>
</systemVariables>
</configuration>
</plugin>
搜索错误本身并没有让我找到解决方案。
2）“修复”上面的错误，仍然没有服务器
我注释掉了所有与 Jetty 相关的代码和依赖项，然后重新部署。这次没有发生错误，但不幸的是在 localhost 下也没有可用的服务器。
3) 致命错误意外元素
在此之后，我添加了“tomcat-websocket”依赖项来替代“javax-websocket-server-impl”依赖项
<!-- <dependency>
<groupId>org.eclipse.jetty.websocket</groupId>
<artifactId>javax-websocket-server-impl</artifactId>
<version>9.4.1.v20170120</version>
</dependency>-->
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-websocket</artifactId>
<version>9.0.10</version>
</dependency>
这导致以下错误：

以上所有错误都发生在 ActiveWeb/ActiveJDBC 的 2.0 和 2.1-SNAPSHOT 版本中。
那么，有没有办法让 ActiveWeb 与 TomEE plus 一起工作？
