出现的错误是:
19:09:30,077 ERROR [[default]] Servlet.service() for servlet default threw exception
java.lang.AbstractMethodError: org.apache.catalina.connector.RequestFacade.isAsyncStarted()Z
我已经在这个主题上检查了几个堆栈溢出帖子,但是对于isAsyncStarted()Z,所有帖子都引用了“NoClassDefFoundError”。我处于停顿状态,因为当我尝试访问localhost时:8080 / appname /抛出此异常。
我读到javax.servlet-api-3.1.0.jar可能是个问题,但我不确定为什么我的错误与其他错误不同。
我知道这很模糊,但我想有人会遇到这个问题w / wicket servlets。
我是否缺少使用Wicket / Jboss / Spring的重要配置? (如果需要,我可以提供其他信息)

答案 0 :(得分:1)
您需要升级到servlet API 3的Tomcat 7或servlet API 3.1的Tomcat 8。您必须打包WAR中的任何servlet API jar
更新
您无法在JBoss AS 4上运行它。您至少需要JBoss AS 7或EAP 6或WildFly 8。

Wicket 7依赖于Servlets 3,你的类路径上似乎有一个旧版本。
