tuscany中remotable接口

运行了一下SOA核心及应用第五章的实现一个web服务中的代码，发现老是跑不通，于是试着跑了下代码中对于web服务测试的代码，如下：

@Test
public void testQueryRemainningWS() throws InterruptedException,
			MalformedURLException, ServiceException, RemoteException {
		Service  service = new Service();
		Call call    = (Call) service.createCall();
		call.setTargetEndpointAddress(new URL("http://localhost:8080/AccountInfo"));
		call.setOperationName(new QName("http://accountinfo", "queryRemainning"));		  
		String ret = (String) call.invoke( new Object[] { "C01" } );
		assertNotNull(ret);
		assertEquals("100.0",ret);
	}

原理也很简单，就是按照axis的客户端要求发起web服务调用看看结果。我运行后发现找不到queryRemainning方法，于是debug进去看看。发现tuscany在InterfaceContractMapperImpl.map(Interface, Operation)，这个函数里面做了接口与操作的转换。我的目的是wsdl转java，在这里比较的时候步骤比较多，其中有个步骤会比较两个接口是不是都是remotable的，如下：

 public boolean isCompatible(Operation source, Operation target, boolean remotable)
    {
label0:
        {
            if(source == target)
                return true;
            if(source.isDynamic() || target.isDynamic())
                return true;
            if(!source.getName().equals(target.getName()))
                return false;
           if(source.getInterface().isRemotable() != target.getInterface().isRemotable())       
                return false;
            DataType sourceOutputType = source.getOutputType();
            DataType targetOutputType = target.getOutputType();
            if(!isCompatible(targetOutputType, sourceOutputType, remotable))
                return false;
            boolean checkSourceWrapper = true;
            List sourceInputType = (List)source.getInputType().getLogical();
            if(source.isInputWrapperStyle() && source.getInputWrapper() != null)
            {
                sourceInputType = (List)source.getInputWrapper().getUnwrappedInputType().getLogical();
                checkSourceWrapper = false;
            }
            boolean checkTargetWrapper = true;
            List targetInputType = (List)target.getInputType().getLogical();
            if(target.isInputWrapperStyle() && target.getInputWrapper() != null)
            {
                targetInputType = (List)target.getInputWrapper().getUnwrappedInputType().getLogical();
                checkTargetWrapper = false;
            }
            if(checkSourceWrapper != checkTargetWrapper)
                return true;
            if(sourceInputType.size() != targetInputType.size())
                return false;
            int size = sourceInputType.size();
            for(int i = 0; i < size; i++)
                if(!isCompatible((DataType)sourceInputType.get(i), (DataType)targetInputType.get(i), remotable))
                    return false;

            Iterator i$ = target.getFaultTypes().iterator();
            boolean found;
label1:
            do
            {
                if(!i$.hasNext())
                    break label0;
                DataType targetFaultType = (DataType)i$.next();
                found = true;
                Iterator i$ = source.getFaultTypes().iterator();
                DataType sourceFaultType;
                do
                {
                    if(!i$.hasNext())
                        continue label1;
                    sourceFaultType = (DataType)i$.next();
                    found = false;
                } while(!isCompatible(targetFaultType, sourceFaultType, remotable));
                found = true;
            } while(found);
            return false;
        }
        return true;
    }

在代码中11行的地方return了，于是查的新的tuscany要求java接口必须声明为remotable才可以发布为外部service。这里tuscany用了值传递，也就是用xml做wsdl和java接口之间的数据传递。
这是关于remotable接口的说明：
Annotation used to indicate a Java interface as remotable. Remotable interfaces use pass-by-value semantics, can be published as entry points and used for external services.
将原有代码的interface加remotable 注解后程序跑通！！！

package samples;

import org.osoa.sca.annotations.Remotable;

@Remotable
public interface AccountInfo {
	
	public String queryRemainning(String accountId);
}
