I am trying to create a sample axis2 ServiceClient. It is throwing below error

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

The axiom-impl.jar is present in the classpath. Below is the code snippet. In the console I can see that sysout statement "Entered" is displayed, after that its throwing error at ServiceClient object creation. Have tried using different versions of the axiom-impl.jar (1.2.12, 1.2.13, 1.2.7, 1.2.5) but still getting the same error.

     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);
}

推荐答案

通过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).

Solved this by replacing all the three individual axiom jars( axiom-impl-1.2.13.jar, axiom-dom-1.2.13.jar and axiom-api-1.2.13.jar) by just axiom.jar.
