我正在尝试创建一个示例axis2 ServiceClient。它抛出错误

axiom-impl.jar存在于类路径中。下面是代码片段。在控制台中，我可以看到显示 sysout 语句“Entered”，然后在创建 ServiceClient 对象时抛出错误。尝试使用不同版本的axiom-impl.jar(1.2.12, 1.2.13, 1.2.7, 1.2.5) 但仍然遇到相同的错误。

     public static String testFunction(String testData) throws Exception {
     System.out.println("Entered");
    //Create a service client
    ServiceClient client = new ServiceClient();
    System.out.println("Before calling set end point");
    //Set the endpoint address
    client.getOptions().setTo(new EndpointReference(EPR));
    System.out.println("After calling set end point");
    System.out.println("getPayload(url)="+getPayload(testData));
    //Make the reqest and get the response
    OMElement resp = client.sendReceive(getPayload(testData));
    //Extract the URL and return
    return extractUrl(resp);
}

我遇到了同样的错误，但经过长时间的努力，终于通过使用 axiom-api 1.2.12 和 axiom-impl 1.2.12 解决了。

通过仅用 axiom.jar 替换所有三个单独的公理 jar（axiom-impl-1.2.13.jar、axiom-dom-1.2.13.jar 和 axiom-api-1.2.13.jar）解决了这个问题。

当我使用上面的 jar 时，我遇到了另一个错误。java.lang.ClassCastException：java.lang.ClassCastException：org.apache.axiom.om.impl.llom.factory.OMLinkedListImplFactory

我不得不将每个 jar 的版本增加到 1.2.14

我有同样的错误。我确实用 axiom.jar 替换了单个公理 jar（axiom-impl-1.2.13.jar、axiom-dom-1.2.13.jar 和 axiom-api-1.2.13.jar），但错误仍然发生。

错误的根本原因是 META-INF/axiom.xml 文件的位置。在我的例子中，当 J2EE 服务器容器的 XMLParser 在 jar 文件中本地化时，它无法打开 axion.xml 文件。

我不得不将 META-INF/axiom.xml 复制到 WEB-INF/classes/META-INF/axiom.xml 中。
