tomcat - JBWEB000250 : Child container with name already exists

Question

我已经在 J​​Boss 中部署了 ear，它由几个 war (Web Archive) 组成。部署的 ear 文件基本上是由 ant 通过在开始 ant 构建之前设置 TOMCAT_HOME 来构建的。

set TOMCAT_HOME=C:\apache-tomcat-6.0.32

我遇到以下错误。我将它部署在 JBoss EAP 6.4.0.GA (AS 7.5.0.Final-redhat-21)

11:38:34,340 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC000001: Failed to start service jboss.web.deployment.default-host./: org.jboss.msc.service.StartException in service jboss.web.deployment.default-host./: Failed to start service at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1936) [jboss-msc-1.1.5.Final-redhat-1.jar:1.1.5.Final-redhat-1] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [rt.jar:1.8.0_45] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [rt.jar:1.8.0_45] at java.lang.Thread.run(Thread.java:745) [rt.jar:1.8.0_45]

这个项目是一个遗留项目。项目lib目录下有Struts 1.2.9、Springs-2.0.8、Hibernate-3.2.6 jar文件，Web Archives (.war)的\WEB-INF\下有相同配置。

基本上我是将应用程序从 Websphere 移植到 JBoss

我该如何解决或克服这个问题。

Answer 1

在 standalone.xml 中，这将是 true enable-welcome-root。如果你把它设为假，你可以在 / 上下文中部署一个网络存档 .war....

如果 enable-welcome-root 保持为真，那么就会出现一些默认的 jboss 网页。因此，这需要更正以在 / 上下文中部署 Web 应用程序。

    <subsystem xmlns="urn:jboss:domain:web:2.1" default-virtual-server="default-host" native="false">
        <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
        <virtual-server name="default-host" enable-welcome-root="false">
            <alias name="localhost"/>
            <alias name="example.com"/>
        </virtual-server>
    </subsystem>
