Java错误消耗WCF服务

Question

I'm started to develop a Web Service with WCF and created a WCF Service poject. I let all as it was and imported the service in netbeans as JAX WS service. All seems to be fine.

Service1 test= new Service1();
CompositeType ct=new CompositeType();
ct.setBoolValue(Boolean.TRUE);
ObjectFactory factory=new ObjectFactory();
ct.setStringValue(factory.createString("StringValue"));    
CompositeType result= test.getBasicHttpBindingIService1().getDataUsingDataContract(ct);

I can send the request. I can break in Visual studio and see the CompositeType object. But the object is not as it should be:

• The bool value is set as expected to true .
• The string value is still null .
• When i manipulate the string value in the WCF Service and give the change object back the string is set correct and i can read it in java.

Why can't i post the CompositeType to java but can consume it?

It's hard to tell from just the detail you've provided.

Here is what I suggest:

• Enable tracing on the service side, generate tracing logs, and analyze with SvcTraceViewer. To do this, follow the instructions at this MSDN article on using the service trace viewer . Notice what's different between the first and second time.

• Turn on debug exceptions. This is done by turning in includeExceptionDetailInFaults, which you can do by following the instructions here . Notice what's different between the first and second time.

• Use Fiddler to monitor the wire traffic on both the client side and the service side.

Generally, once you do this, you should plenty of more info on what's going funky at the service side and can diagnose the issue pretty quickly. Try it, and please report back! :)

I also lost 2 hours in this!

The problem is in java code :)

Instead of this

ct.setStringValue(factory.createString("StringValue"));  

use this

ct.setStringValue(factory.createCompositeTypeStringValue("StringValue"));
