Question

我正在尝试创建一个示例axis2 ServiceClient。抛出错误

axiom-impl.jar出现在类路径中。以下是代码段。在控制台中，我可以看到sysout语句“已输入”，之后在ServiceClient对象创建时抛出错误。尝试使用axiom-impl.jar（1.2.12,1.2.13,1.2.7,1.2.5）的不同版本，但仍然得到相同的错误。

     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);
}

Answer 1

通过axiom.jar替换所有三个单独的公理罐（axiom-impl-1.2.13.jar，axiom-dom-1.2.13.jar和axiom-api-1.2.13.jar）来解决这个问题。

Answer 2

我有同样的错误，但最终在经过长时间的斗争后使用axiom-api 1.2.12和axiom-impl 1.2.12解决了。

Answer 3

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

我必须将版本增加到每个jar的1.2.14

Answer 4

我有同样的错误。我确实用axiom.jar替换了各个公理罐（axiom-impl-1.2.13.jar，axiom-dom-1.2.13.jar和axiom-api-1.2.13.jar），但错误仍在发生。

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

我必须将META-INF / axiom.xml复制到WEB-INF / classes / META-INF / axiom.xml中。
