Consuming web services

[bmelloni]

Hello everybody! I have one problem. I tried to Jobs autowire the helper class but when I run the application on tomcat I get the following error:The Stellenmarkt prefix "context" for element "context:component-scan" is not bound. Do you have any clue?
For the record: everything else works fine (meaning Stellenangebote that without the helper I can run the helloworld webservice).

You are probably missing the schema definition (xmlns:context, xsi:schemaLocation) in your context file <beans> tag.

For anyone who might read this thread...

In the end I did not need to download Spring Web Services to consume web services. Spring 2.5.6 supplied most of what I neeed.

I found wsimport in my path (I am guessing from Java 6) and it generated the classes needed.

I did need some additional JARs to satisfy dependencies. One was saaj-impl-1.3.2.jar. I believe there were other dependencies but they were satisfied by JARs that I already had in my classpath.

I hope this helps the next person that hits this wall.

Hi,

I experience the same problem. Using the same webservice as in the head of this topic...:

I would like to access the Webservice from a Spring-managed bean like this:

  @WebServiceRef(wsdlLocation=" http://www.webservicex.com/ValidateEmail.asmx?WSDL")
  private ValidateEmail service;

I imported the wsdl:

wsimport  -target 2.1 -p com.ws -s src/main/java/ -extension -Xnocompile  http://www.webservicex.com/ValidateEmail.asmx?WSDL

During deployment I receive this exception:

ERROR - ContextLoader.initWebApplicationContext(220) | Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'emailDao': Injection of resource dependencies failed; nested exception is com.sun.xml.internal.ws.model.RuntimeModelerException: A WebService annotation is not present on class: com.ws.ValidateEmail
	at org.springframework.context.annotation.CommonAnnotationBeanPostProcessor.postProcessPropertyValues(CommonAnnotationBeanPostProcessor.java:300)
...
Caused by: com.sun.xml.internal.ws.model.RuntimeModelerException: A WebService annotation is not present on class: com.ws.ValidateEmail
	at com.sun.xml.internal.ws.model.RuntimeModeler.getPortTypeName(Unknown Source)

I checked the generated class, and it really lacks the @WebService annotation and starts like this:

  @WebServiceClient(name = "ValidateEmail", targetNamespace = "http://www.webservicex.net", wsdlLocation = "http://www.webservicex.com/ValidateEmail.asmx?WSDL")
public class ValidateEmail
    extends Service

I received during wsimporting a number of warnings...:

parsing WSDL...


[WARNING] SOAP port "ValidateEmailSoap12": uses a non-standard SOAP 1.2 binding.

generating code...

If I use ValidateEmailSoap, I receive:

@WebServiceRef(wsdlLocation=" http://www.webservicex.com/ValidateEmail.asmx?WSDL", type=ValidateEmail.class)
private ValidateEmailSoap service;

Caused by: java.lang.IllegalStateException: Specified field type [interface com.ws.ValidateEmailSoap] is incompatible with resource type [com.ws.ValidateEmail]

I use JDK 1.6.0_21 with JAX-WS RI 2.1.6 and Spring 3.0.3.RELEASE.
Any hints what could be the solution here?

OK,

this is the right combination:

@WebServiceRef(ValidateEmail.class)
private ValidateEmailSoap service;

An addition to my original post:

Even though I was successful, I tried several other ways to write and call web services.

In the end I found that the simplest and cleanest is Apache CXF, using the code-first approach:

• To write a service, you simply write a java bean, then you expose it through pretty simple configuration in your spring context.
• To call a service, again you just do some configuration in your spring context, then load the auto-generated bean that proxies the call to the web service.
• So basically writing and calling is done through POJOs. And the configuration is all in the Spring Context, plus adding the necessary libraries.

You almost don't have to worry about the fact that it is a web service.

Hi,

thanks for your suggestion!

Upon your post I tried Apache CXF, and found cool (surprises, that it is documented well enough).
I have also found decent Maven plugins for WSDL->Java and XSD->Java inside, which I was longing for a while...
