在 Jboss 6.3.0 EAP 中部署 Java WS 时出错

Question

我正在将使用 Java WS 的应用程序从 Jboss 5.1.0 迁移到 Jboss 6.3.0 EAP。它适用于 Jboss 5.1.0，但在 Jboss 6.3.0 EAP 中部署相同时出现错误。

我了解 Jboss 6.3.0 EAP 使用 CXF 实现 web 服务，但我正在寻找简单的 Java WS 以使用标准 Java EE 环境。

在 jboss-deployment-structure.xml 中尝试了以下操作

<exclude-subsystems>
    <subsystem name="webservices" />
</exclude-subsystems>

这在部署时消除了异常，但在为服务调用 wsdl 时出现 Classcast 异常

http://localhost:8080/myapp/myservice?wsdl

JBWEB000235：为 servlet MyWebService 分配异常：java.lang.ClassCastException：com.example.webservice.endpoint.DataService 无法转换为 javax.servlet.Servlet

有什么想法吗？

Answer 1

问题在于在您的部署中捆绑 asm.jar。
尝试删除它并将其添加到您的jboss-deployment-structure.xml：

<jboss-deployment-structure>
    <deployment>
       <dependencies>
            ...
            <module name="asm.asm" />
            ...
        </dependencies>
    </deployment>
</jboss-deployment-structure>

Answer 2

The answer 为我解决的问题是：

我遇到了同样的问题。仅添加 jboss-deployment-structure.xml 为 WAR 文件工作。如果我在 EAR 中解散 WAR，我得到了 错误返回。所以我加了

  <global-modules>
    <module name="asm.asm" slot="main"/>
  </global-modules>

到当前的jboss配置，即standalone-full.xml中 对我来说很好。

所以如果有人偶然发现这个问题，请尝试一下。

Rifer 这个页面也是。 https://access.redhat.com/solutions/690353

当给定类的特定方法不是时抛出上述错误 成立。因此，用户在他们的应用程序和类中打包 asm jar jar 中包含的“org.objectweb.asm.MethodWriter”没有 方法“公共无效访问标签（org.objectweb.asm.Label）；”因此 得到“java.lang.NoSuchMethodException”。
