无法在Weblogic 12c（12.2.1）中部署CXF3.x JAX-RS服务（12.2.1）

将使用CXF3.x构建的JAX-RS服务从weblogic 12.1.3升级到12.2.1后，我遇到以下奇怪问题无法在Weblogic 12c（12.2.1）中部署CXF3.x JAX-RS服务（12.2.1）

请注意，我正在使用CXF，而不是泽西岛，但似乎Weblogic试图使用它（它不会发生在12.1.3）。我禁用它在配置文件中以下这个建议：https://jerometambo.github.io/blog/2016/12/13/How-to-use-CXF-3x-implementation-of-JAX-RS-20-REST-with-Weblogic-12c.html

在默认配置中，WebLogic想要使用它的内部实现（JAX-RS 2.0和序列化）部署REST Web服务（错误500）：

META-INF/WebLogic的application.xml中

我不知道这是我的项目的特定问题，或者它是一个weblogic的问题。我发现类似的问题，如this和this，我试图使用它们。

替代方法

它的工作原理，如果我使用部署之前其他CXF模块默认的JAX-RS实施和删除WEB-INF/lib/javax.ws.rs-api-2.0.1.jar。也许weblogic会进行某种内部初始化。

myapp.ear 
    init.war (JAX-RS with CXF and removing javax.ws.rs-api-2.0.1.jar) 
    myapp.war (JAX-RS with CXF and weblogic configuration)

@pedrofb，这可能不完全回答你的问题，但是，我曾经有一个与Tomcat类似的问题。症状是相似的，问题并不是真正归因于不同类别存在于不同罐子中的现象，即罐子阴影。这是由于类加载器阴影。在Tomcat中，如果应用程序类加载器可以找到一个类（只从WEB-INF/lib或类中加载），那么类加载实际上是倒置的，而不是通常的“ask-your-parent-classloader-first”类型，那么classloader加载类。现在，就我而言，我认为，由于JAX-RS jar包存在于WEB-INF/lib中，因此它将在Web应用程序级别从那里加载。然而，当同一个对象被传递给容器时，它试图将其转换为相同的类，但是在由不同的类加载器加载的容器级别上。由不同的类加载器加载的类被认为是不同的;这将是ClassCastException的原因。

这也解释了为什么从WEB-INF/lib中删除JAX-RS jar时没有ClassCastException。这里的解决方法是有限的，或者像你一样从WEb-INF/lib中删除JAX-RS jar。 （这可能存在问题，但可以在非生产服务器上进行试验），将容器JAX-RS jar替换为所需的jar。

正如我所说，这可能不会完全解决您的问题，但可能指向问题来自何方。 [正如我几年前注意到的那样，Weblogic使用tomcat作为它的Web容器核心（不知道它是否仍然是相同的），并且改变了包名称，如com.bea.weblogic.org.apache.tomcat ...]。

希望这会有所帮助。

感谢您的回答。我确信它是* wls 12.2.1 *的类加载器问题，因为在* wls 12.1.3 *和* tomcat *中它完美运行。我试图用我的代替wls JAX-RS .jar，但我没有运气 – pedrofb
