how to deploy Spring WS with JaxBMarshaller

[virfal]

i tried to make all the configurations as given in spring web service documentation in web.xml and spring-ws-servlet.xml for MarshallingEndpoint with JaxBMarshalling/Unmarshalling.

I have used dynamic wsdl generation bean in spring-ws-servlet.xml

I have no idea how to deploy it to server so that it exposes it as web service.

By just deploying it as web application to oc4j server its not configuring it as service


I have attached the config files....


Somebody please help me in this issue...

Hi Virfal,

Checking your configuration files, they look pretty straight forward. What is the exact error you're getting? If it is a 404 (File Not Found), this could mean that your web application was not properly deployed or you are accessing an incorrect port. However, if it is a 500 (Internal Server Error), you would have to check the SystemOut log files of your OC4J Application Server for details. You may want to post the logs and the schema as well. Remember you first need to check if you were able to generate a proper WSDL. Looking at your config files, the URL of the WSDL should be something like: http://<hostname>:<port>/<WebApplica...me>/Hello.wsdl

Hope that helps.

It was a 404(File not Found) .....so it was not getting deployed properly...i added following to web.xml and it started creating all beans in config file .......

<listener>
<listener-class>org.springframework.web.context.ContextLoade rListener</listener-class>
</listener>


Still its not generating wsdl and am getting error while creating beans on deployment as following:


Error creating bean with name 'helloEndpoint' defined in ServletContext resource [/WEB-INF/spring-ws-servlet.xml]: Cannot resolve reference to bean 'marshaller' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'marshaller' defined in ServletContext resource [/WEB-INF/spring-ws-servlet.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax.xml.bind.JAXBContext.newInstance([Ljava/lang/ClassLjavax/xml/bind/JAXBContext;




I tried running application in embedded oc4j with index.jsp to get web context....then while loading application it gave same error with following more details................

I tried different versions of JAXB libraries but its not helping it out (dont know whether its conflict between JAXB libs and spring libs having marshalling classes).....

Without adding JAXB libs its giving me error for attachment bean in jaxb... somewhere its getting referenced from spring libs

error is as follow:
Cannot resolve reference to bean 'marshaller' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'marshaller' defined in ServletContext resource [/WEB-INF/spring-ws-servlet.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/attachment/AttachmentUnmarshaller

[RShelley]

You're getting that error because your "marshaller" bean is failing to be constructed properly, so it doesn't exist to be injected into your endpoint:

Caused by: org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'marshaller' defined in ServletContext resource [/WEB-INF/spring-ws-servlet.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError:

I'm not an expert, but this is what my "marshaller" bean looks like:

    <bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <description>
            The JAXB 2 Marshaller is used by the endpoints.
        </description>
        <property name="contextPath" value="com.mg21.shotgun.ws.bindings.catalog"/>
    </bean>

Where "com.mg21.shotgun.ws.bindings.catalog" is the package to my XJC generated classes.

[virfal]

replacing "classesToBeBound" property with "contextPath" given in ur reply...

it started giving me different error as follow.....


Cannot resolve reference to bean 'marshaller' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'marshaller' defined in ServletContext resource [/WEB-INF/spring-ws-servlet.xml]: Invocation of init method failed; nested exception is org.springframework.oxm.jaxb.JaxbSystemException: Unable to locate jaxb.properties for package com.mg21.shotgun.ws.bindings.catalog; nested exception is javax.xml.bind.JAXBException: Unable to locate jaxb.properties for package com.mg21.shotgun.ws.bindings.catalog

dont know how this approach works

[RShelley]

Well, you need to change the contextPath to point to the package containing your XJC generated classes. It looks like you just copied and pasted my example without changing anything.

[virfal]

I changed it to my package where my beans classes are there which is "com.beans" . There are no other classes generated by XJC. Even with existing annotation @XMLRootElement for each bean is it required to create classes using XJC??? just lemme know steps needs to be executed to get all the dependencies for using JAXB2Marshaller and exposing Endpoint as service.
when i tried giving path to "com.beans" for beans classes which we need to marshall ...it gave me same error as above "Unable to locate jaxb.properties......."

No idea where to look into to figure out the solution


also we are using JAXB2 in other parts of application so any solution for any one out of JAXB1 or JAXB2 marshaller is fine......

if any body have working solution as proof of concept just send it to me on virfal@yahoo.com........... i need to deploy it on oc4j server



or just tell me jaxb libs to be used which is compatible to spring libs....so that i can successfully use "classesTobeBound" property of "org.springframework.oxm.jaxb.Jaxb2Marshaller" mapping..(I found this approach very promising)....





Thanks in advance...

[virfal]

i have created shared lib in oc4j containerto place jaxb libs...and it worked....it has successfully deployed the application with following logs :

but when i try to invoke this service using http://localhost:8888/SpringWS/helloWorldService it gives HTTP 404 error

and with http://localhost:8888/SpringWS/helloWorldService/Hello it gives HTTP 405 method not allowed error.......................................dont know what the issue is



i have attached the latest config files ....can anyone please check it out whether m missing anything to direct web service request properly or if its exposing service properly

[RShelley]

and with http://localhost:8888/SpringWS/helloWorldService/Hello it gives HTTP 405 method not allowed error.......................................dont know what the issue is

That's the proper response to a GET request to the service. You have to POST the SOAP request to the service to get it to respond.

[virfal]

Hi RShelly,

Thanks for assurance that m on right way...

but i have no idea like how to post the SOAP request to the service???

I need to call spring web services from two types of client:

1)--->Java client which uses spring

org.springframework.ws.client.core.WebServiceTempl ate

setting marshaller,unmarshaller and defaultUri .....for eg. following config gives 404 error while calling using WebServiceTemplate marshallsendandreceive(obj)

<bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServi ceTemplate">
<property name="marshaller" ref="xmlBeansMarshaller"/>
<property name="unmarshaller" ref="xmlBeansMarshaller" />
<property name="defaultUri" value="http://localhost:8888/SpringWS/helloWorldService/Hello"/>
</bean>

Please somebody give resolution for above....


2)---> calling Endpoint service through BPEL process/ESB Routing service...



by pasting url in browser it was giving 405 method not found error but from spring client it gives 404 error....


Help me with creating client so that it successfully calls exposed service....



(Got confident as able to view dynamically generated WSDL ....... but strange thing i found in oc4j enterprise manager is .....this deployment is shown as application only ...not as webservice....so i still doubt whether it will work same way as any other web-service like for eg JAX-RPC web service....or need to do something else to make it a web service).....
