OSGi ClassNotFoundException WSServletContextListener

【问题标题】：OSGi ClassNotFoundException WSServletContextListenerOSGi ClassNotFoundException WSServletContextListener

【问题描述】：

我正在编写一个包含 Web 服务服务器 (com.sun.xml.ws/jaxws-rt) 的 OSGi 包 (hu.libra.commons.osgi.core.wsbundle)。 这是可行的，但是生成的包包含 5Mb 的嵌入式 jar，我不想将它包含在我所有的 web 服务包中（毕竟 OSGi 是关于模块化的），我想把它们放入一个“webservice core”包中（ hu.libra.commons.webservice.core) 和我所有的网络服务都将依赖于此。

但是当我尝试这样做时，我得到 java.lang.ClassNotFoundException: com.sun.xml.ws.transport.http.servlet.WSServletContextListener 异常。 有什么问题？

目前正在使用 pom.xml (hu.libra.commons.osgi.core.wsbundle)

接下来的两个pom不工作，我得到java.lang.ClassNotFoundException: com.sun.xml.ws.transport.http.servlet.WSServletContextListener 异常。

【问题讨论】：

  • 您应该从这些 POM 中删除 &lt;Import-Package&gt; 和 &lt;DynamicImport-Package&gt; 部分。

标签： java web-services maven osgi classloader


【解决方案1】：

问题可能是 com.sun.xml 包在 Java 框架中 - 因为我知道 jaxws 运行时是随 JRE 一起提供的。 java框架包可以定义在容器的启动委托包中，也可以定义为框架扩展包。

示例扩展 Pom：

<description>
        This bundle extends the System Bundle export
        list with the sun.misc package such
        that OSGi bundles may refer to Sun's misc implementation
        without the OSGi framework itself to provide it in a
        non-portable way.

你的 com.sun.misc 包可以通过 bundle 导入。

【讨论】：

  • 在使用导入和“org.osgi.framework.system.packages.extra”之后，ClassNotFoundException 消失了，现在我得到了“javax.servlet.UnavailableException: Servlet class com.sun.xml .ws.transport.http.servlet.WSServlet 不是 javax.servlet.Servlet”异常。这是否意味着我使用了两个版本的 javax.servlet.Servlet？我该如何解决这个问题？
