Apache的Axis2中试图打Web服务时抛出的NoSuchMethodError？ [英] Apache Axis2 throws NoSuchMethodError when trying to hit web service?

问题描述

我想打使用Axis2以下Web服务： HTTP：//www.webservicex。净/ geoipservice.asmx？WSDL

I am trying to hit the following web service with axis2: http://www.webservicex.net/geoipservice.asmx?WSDL

我有本地的Axis2和我产生我的课通过下载WSDL到本地驱动器并运行：

I have Axis2 locally, and I generated my classes by downloading the wsdl to my local drive and running:

./wsdl2java.sh -uri geoipservice.wsdl -p geoip -d xmlbeans -s -o geoip

这产生在它的build.xml文件，然后我跑了进来蚁族一个build目录，并产生libs文件夹中的客户机罐子。

This produced a build directory with a build.xml file in it, which i then ran "ant" in, and it produced a client jar in the libs folder.

我放弃了这个罐子到类路径，然后我尝试使用以下code打服务：

I dropped this jar onto my classpath, and then I tried to hit the service using the following code:

GeoIPServiceStub stub = new GeoIPServiceStub("http://www.webservicex.net/geoipservice.asmx?WSDL");
GetGeoIPDocument req = GetGeoIPDocument.Factory.newInstance();
GetGeoIP gic = req.addNewGetGeoIP();
gic.setIPAddress("74.125.91.105");  // google.com
GetGeoIPResponseDocument resp = stub.getGeoIP(req);
System.out.println(resp.getGetGeoIPResponse().toString());

事情似乎在第一次运行，我看到回来syslog中的结果，但它完成之前，抛出此异常：

Things seem to run at first, and I see the results coming back in the syslog, but before it finishes it throws this exception:

java.lang.NoSuchMethodError: org.apache.axiom.om.impl.OMStAXWrapper.<init>(Lorg/apache/axiom/om/OMXMLParserWrapper;Lorg/apache/axiom/om/OMElement;Z)V
at org.apache.axiom.om.impl.llom.OMStAXWrapper.<init>(OMStAXWrapper.java:52)

at geoip.GeoIPServiceStub.fromOM(GeoIPServiceStub.java:767)
at geoip.GeoIPServiceStub.getGeoIP(GeoIPServiceStub.java:325)

我GOOGLE了全国各地，并一直没能找到是什么原因造成这一点。谁能帮我找到我做错了什么？谢谢你。

I've googled all over and haven't been able to find what is causing this. Can anyone help me find what I'm doing wrong? Thank you.

推荐答案

您获得NoSuchMethodErrors如果你的编译器使用不同的类定义（编译期间）来创建.class文件，然后在JVM运行时。

You get NoSuchMethodErrors if your compiler used a different class definition (during compilation) to create your .class file then the jvm has at runtime.

在你的情况，它遗漏了 org.apache.axiom.om.impl.OMStAXWrapper（org.apache.axiom.om.OMXMLParserWrapper，org.apache.axiom.om.OMElement）构造函数

In your case, it misses the constructor for org.apache.axiom.om.impl.OMStAXWrapper(org.apache.axiom.om.OMXMLParserWrapper, org.apache.axiom.om.OMElement)

这可能意味着你打错org.apache.axiom库某处类路径中。

It probably means you have the wrong org.apache.axiom library somewhere on your classpath.
