我在以下项目设置中遇到了类加载问题： 我们的EAR包含多个WAR，其中两个是相关的，我们称之为web和ejb。我们正在使用Websphere 8。 现在，ejb.war包含许多web服务，其中一个是新开发的 - ejb.war中的一些类实际上是由axis2生成的。 要调用此ws并在web.war中处理响应，我们必须在EAR中包含一些jar，并调整每次战争的清单。 （？）
我将axiom-api-1.2.13.jar包含在EAR文件中，并添加到web和ejb WARS的清单中。需要处理响应，其中包含Base64EncodedFileType对象。
现在我得到一个包含以下内容的异常：
Caused by: java.lang.VerifyError: JVMVRFY013 class loading constraint violated; class=ch/teledata/ws/schema/bisv3_6/Request ...
我发现此处提到此错误http://axis.apache.org/axis2/java/core/docs/app_server.html - 这是关于webshpere和axis2的已知问题。我如上所述修改了WAS的classLoader，但它没有解决问题。该网站提到了一个axis2.xml，无论我在战争/耳朵中包含哪个地方，它都没有效果。有没有人遇到这样的问题？还有什么可能遗失？
也许我没有包含另一个可以在配置中读取的axis2 jar？另外，我不确定是否必须将axiom.jar包含在EAR中，而不是ejb.WAR。
我完全不知道在哪里寻找问题，所以不要犹豫向我提出问题/指示。
如果你已经读过这篇文章了，那就是你的时间！
这里有完整的堆栈跟踪（调用wsStub的方法是从Web层调用的）：

答案 0 :(得分：1)
堆栈跟踪指示当类加载器尝试加载ADB生成的类（可能由Axis2 Web服务客户端使用）时发生错误。如果您想这样做，那么您还需要在应用程序中包含相关的Axis2 JAR。基本上，您需要包含在WebSphere之外运行代码所需的所有库。如果然后使用PARENT_LAST配置类加载器，那么它应该可以工作。
另一方面，如果您的应用程序尝试使用Axis2模块（例如，用于WS-Addressing），则axis2.xml的更改是必需的。
