本文记录了在使用Java发布Web Service时遇到的问题及解决过程。从wsimport生成接口和实现类，到通过META-INF发布自定义wsdl，期间遇到了多个错误，包括：多schema目标命名空间错误、wsdl操作缺失、方法参数与wsdl不匹配等。通过查阅文档和添加正确注解，最终成功发布并验证了wsdl和xsd的一致性。

        最近学习做Webservice项目，模仿物流发货，A公司每向B公司一车货，发2次消息，分A出发时和到达B时，2消息内容相同。消息包含车号、司机、货物清单及可能是集装箱等。wsdl文件：

         用wsimport生成相应的类，主要的是接口LGSService，

@WebService(name = "LGSService", targetNamespace = "http://hjs.com/services/atob/lgsservice/v1.0/")
@XmlSeeAlso({
    com.hjs.schema.atob.logistics.ObjectFactory.class,
    com.hjs.schema.atob.common.ObjectFactory.class
})
public interface LGSService ｛
    @WebMethod(operationName = "CargoArrival", action = "http://hjs.com/services/atob/lgsservice/v1.0/CargoArrival")
    @RequestWrapper(localName = "CargoArrival", targetNamespace = "http://hjs.com/schema/atob/logistics/", className = "com.hjs.schema.atob.logistics.CargoArrival")
    @ResponseWrapper(localName = "ResponseMessage", targetNamespace = "http://hjs.com/schema/atob/common/", className = "com.hjs.schema.atob.common.ResponseMessageType")
    public void cargoArrival(
        @WebParam(name = "Head", targetNamespace = "http://hjs.com/schema/atob/logistics/")
        com.hjs.schema.atob.logistics.BaseMessageType.Head head,
        @WebParam(name = "LGS", targetNamespace = "http://hjs.com/schema/atob/logistics/")
        List<LGSType> lgs,
        @WebParam(name = "REFF_NO", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<BigInteger> reffNO,
        @WebParam(name = "SENDER", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<String> sender,
        @WebParam(name = "RECEIVER", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<String> receiver,
        @WebParam(name = "RECEIVED_DTTM", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<XMLGregorianCalendar> receivedDTTM,
        @WebParam(name = "ACKNSTAT", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<BigInteger> acknstat,
        @WebParam(name = "ACKNREMARK", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<String> acknremark);

    
    @WebMethod(operationName = "CargoPreannounce", action = "http://hjs.com/services/atob/lgsservice/v1.0/CargoPreannounce")
    @RequestWrapper(localName = "CargoPreannounce", targetNamespace = "http://hjs.com/schema/atob/logistics/", className = "com.hjs.schema.atob.logistics.CargoPreannounce")
    @ResponseWrapper(localName = "ResponseMessage", targetNamespace = "http://hjs.com/schema/atob/common/", className = "com.hjs.schema.atob.common.ResponseMessageType")
    public void cargoPreannounce(
        @WebParam(name = "Head", targetNamespace = "http://hjs.com/schema/atob/logistics/")
        com.hjs.schema.atob.logistics.BaseMessageType.Head head,
        @WebParam(name = "LGS", targetNamespace = "")
        List<LGSType> lgs,
        @WebParam(name = "REFF_NO", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<BigInteger> reffNO,
        @WebParam(name = "SENDER", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<String> sender,
        @WebParam(name = "RECEIVER", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<String> receiver,
        @WebParam(name = "RECEIVED_DTTM", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<XMLGregorianCalendar> receivedDTTM,
        @WebParam(name = "ACKNSTAT", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<BigInteger> acknstat,
        @WebParam(name = "ACKNREMARK", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
        Holder<String> acknremark);

}


再做一个类LGSServiceImpl实现此接口

@WebService(name = "LGSService", targetNamespace = "http://hjs.com/services/atob/lgsservice/v1.0/")
@BindingType(value = javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_BINDING)
public class LGSServiceImpl implements LGSService {

	@Override
	public void cargoArrival(Head head, List<LGSType> lgs, Holder<BigInteger> reffNO, Holder<String> sender,
			Holder<String> receiver, Holder<XMLGregorianCalendar> receivedDTTM, Holder<BigInteger> acknstat,
			Holder<String> acknremark) {
		// 代码省略。。。
	}

	@Override
	public void cargoPreannounce(Head head, List<LGSType> lgs, Holder<BigInteger> reffNO, Holder<String> sender,
			Holder<String> receiver, Holder<XMLGregorianCalendar> receivedDTTM, Holder<BigInteger> acknstat,
			Holder<String> acknremark) {
		// 代码省略。。。
	}

}

发布此服务

	LGSService ls = new LGSServiceImpl();
	Endpoint.publish("http://localhost:8090/services/atob/lgsservice/v1.0/", ls);


可以正常发布，打开http://localhost:8090/services/atob/lgsservice/v1.0/?wsdl，可以看到wsdl，但那是系统生成的，看起来别扭，也不方便客户端查看。

为了能让客户端查看原装的wsdl和其它schema，可以以META-DATA方式发布，如

	LGSService ls = new LGSServiceImpl();
	Endpoint lgsendpoint = Endpoint.create(ls);
	List<File> metadataFile = new ArrayList<File>();
	     metadataFile.add( new File("src/META-INF/wsdl/LGSService.wsdl"));
	     metadataFile.add( new File("src/META-INF/wsdl/BaseMessage.xsd"));
	     metadataFile.add( new File("src/META-INF/wsdl/ABAWBS.xsd"));
	     metadataFile.add( new File("src/META-INF/wsdl/CONTAINER.xsd"));
	     metadataFile.add( new File("src/META-INF/wsdl/ABLGS.xsd"));
	     metadataFile.add( new File("src/META-INF/wsdl/ResponseMessage.xsd"));
	     
	     List<Source> metadata = new ArrayList<Source>();
	     try {
	    	for(File file : metadataFile){
	    	 	Source source = new StreamSource(new FileInputStream(file));
	    	 	source.setSystemId(file.toURI().toURL().toExternalForm());
	    	 	metadata.add(source);
	    	}
			lgsendpoint.setMetadata(metadata);
			lgsendpoint.publish("http://localhost:8090/services/atob/lgsservice/v1.0/");
			
		} catch (FileNotFoundException | MalformedURLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

不能成功发布，系统报错：

服务器运行时错误: More than one schema for the target namespace http://hjs.com/schema/atob/logistics/

想了好久，什么问题？查看JAX-WS文档及网上资料，感觉是系统无法辨别是生成的wsdl和xsd还是原装META的，应该在类上指定，加上注释

	serviceName = "LGSService", portName = "LGSServiceSOAP",

再发布，系统报：

Method cargoPreannounce is exposed as WebMethod,
 but there is no corresponding wsdl operation with name {http://hjs.com/services/atob/lgsservice/v1.0/}cargoPreannounce in the wsdl:portType{http://hjs.com/services/atob/lgsservice/v1.0/}LGSService

原来是方法上没有加注释，那就加上吧

	@WebMethod(operationName = "CargoArrival", action = "http://hjs.com/services/atob/lgsservice/v1.0/CargoArrival")
    @RequestWrapper(localName = "CargoArrival", targetNamespace = "http://hjs.com/schema/atob/logistics/", className = "com.hjs.schema.atob.logistics.CargoArrival")
    @ResponseWrapper(localName = "ResponseMessage", targetNamespace = "http://hjs.com/schema/atob/common/", className = "com.hjs.schema.atob.common.ResponseMessageType")

再发布，还有错：

javax.xml.ws.WebServiceException: class com.hjs.schema.atob.logistics.CargoPreannounce do not have a property of the name arg0
再找资料，认为类内的方法参数与xsd不一致。参考接口方法的参数，全部复制到实现类里

public void cargoArrival(
		@WebParam(name = "Head", targetNamespace = "http://hjs.com/schema/atob/logistics/")
	        com.hjs.schema.atob.logistics.BaseMessageType.Head head,
	       @WebParam(name = "LGS", targetNamespace = "http://hjs.com/schema/atob/logistics/")
	        List<LGSType> lgs,
	        @WebParam(name = "REFF_NO", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
	        Holder<BigInteger> reffNO,
	        @WebParam(name = "SENDER", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
	        Holder<String> sender,
	        @WebParam(name = "RECEIVER", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
	        Holder<String> receiver,
	      @WebParam(name = "RECEIVED_DTTM", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
	        Holder<XMLGregorianCalendar> receivedDTTM,
	        @WebParam(name = "ACKNSTAT", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
	        Holder<BigInteger> acknstat,
	        @WebParam(name = "ACKNREMARK", targetNamespace = "http://hjs.com/schema/atob/common/", mode = WebParam.Mode.OUT)
	        Holder<String> acknremark
			) {
		// 省略代码。。。
	}


发布！OK啦！打开wsdl，与原装的一致。

分别打开每一个xsd，也与原装发布的一致。算是成功发布了吧。


总结：在写实现类时，要按JAX-WS的要求，或参考接口，分别加上相应的注释，不只是简单实现。

根本原因是项目应用里面缺少tools.jar包，而tools.jar是jdk中提供的一个jar包，我本地电脑配置的环境是jdk的，所以可以正常运行，而服务器上面可能是jre环境，jre里面是没有tools.jar的，所以导致程序报错。这次报错的根本原因就是项目中缺少jdk中的tools.jar包，解决办法就是想一个办法引入tools.jar包，但是需要注意的是，如果我们直接将tools.jar包放入打包之后的工程里面，此时仍然会报错，因为这种方式不生效。到此，这个问题解决啦。
