我已经使用SOAP
为Apache Axis2 1.7.8
Web服务生成了Web客户端。
并且我编写了以下CustomStub
类,该类由stub
类扩展/继承。
public class CustomStub extends Stub {
protected AxisService _service;
protected ArrayList modules = new ArrayList();
protected ServiceClient _serviceClient;
/**
* Get service client implementation used by this stub.
*
* @return service client
*/
public ServiceClient _getServiceClient() {
return _serviceClient;
}
/**
* Set service client implementation used by this stub. Once set, the
* service client is owned by this stub and will automatically be removed
* from the configuration when use of the stub is done.
*
* @param _serviceClient
*/
public void _setServiceClient(ServiceClient _serviceClient) {
this._serviceClient = _serviceClient;
}
/**
* Create a SOAP message envelope using the supplied options.
* TODO generated stub code should use this method, or similar method taking
* an operation client
*
* @param options
* @return generated
* @throws SOAPProcessingException
*/
protected static SOAPEnvelope createEnvelope(Options options) throws SOAPProcessingException {
return getFactory(options.getSoapVersionURI()).getDefaultEnvelope();
}
/**
* Get Axiom factory appropriate to selected SOAP version.
*
* @param soapVersionURI
* @return factory
*/
protected static SOAPFactory getFactory(String soapVersionURI) {
if (SOAP11Constants.SOAP_ENVELOPE_NAMESPACE_URI.equals(soapVersionURI)) {
return OMAbstractFactory.getSOAP11Factory();
} else if (SOAP12Constants.SOAP_ENVELOPE_NAMESPACE_URI.equals(soapVersionURI)) {
return OMAbstractFactory.getSOAP12Factory();
} else {
throw new RuntimeException(Messages
.getMessage("unknownsoapversion"));
}
}

super.finalize();
cleanup();
}
/**

*/
public void cleanup() throws AxisFault {
// service is removed from the service client it self.
_serviceClient.cleanup();
}
/**

*
* @param address

protected void setServiceClientEPR(String address) {
EndpointReference toEPRFromServiceClient = _serviceClient.getOptions().getTo();
toEPRFromServiceClient.setAddress(address);

但是,当我调用Web服务时,出现以下错误:
log4j:WARN找不到记录器的附加程序(org.apache.axiom.locator.DefaultOMMetaFactoryLocator)。
log4j:WARN请正确初始化log4j系统。
线程“主”中的异常java.util.ConcurrentModificationException:当前节点已使用Iterator#remove()以外的方法删除。

最佳答案
当您在OMElement上调用addChild时,该方法将更改要作为子节点添加的节点的父节点。
在调用addChild(omNode)的代码的addHeader块中,您将omNode的父级更改为soapHeaderBlock。因此,下一个hasNext调用失败,说明原始结构已被修改。
试试这个代替:
Iterator children = omElementToadd.getChildElements();
while (children.hasNext()) {
omNode = (OMNode) children.next();
OMElement clonedEl = omNode.cloneOMElement();
soapHeaderBlock.addChild(clonedEl);
}
