axis2调用webservice接口核心代码

public Object invokeOp(String header,String body){     String address = "http://192.26.25.53:8080/fep/services/EHRService";     String namespaceURI = "http://service.fep.hdc.wadata.cn";     String localPart = "EHRSynTransport";     String obj = null;     try {         RPCServiceClient serviceClient = new RPCServiceClient();         Options options = serviceClient.getoptions();             options.setProperty(org.apache.axis2.transport.http.HTTPConstants.CHUNKED,Boolean.FALSE);         options.setTo(new EndpointReference(address));         QName opName = new QName(namespaceURI,localPart);                  Object[] ob = new Object[]{header,body};         Class[] rec = new Class[]{String.class};         obj = (String) serviceClient.invokeBlocking(opName,ob,rec )[0];     } catch (AxisFault e) {         logger.error("调用webservice接口方法错误："+e.getMessage());     }     return obj; }
