Get "Unable to extract web services deployment dat...

Former Member · ‎05-07-2009

Hi All

I'm in the process of migrating several JEE applications from JBoss 4.2.3. I want to do it in such a way that no vendor-specific code or annotations are used since I want to support both JBoss and NetWeaver from the same code line.

When I tried to deploy one of the applications, I got this error:

~~-snip~~-


	2. Client path 'C:\myprojects\ide\eclipse\sap\auth_app\auth_app.ear'
		Deploy status is 'Aborted'
		Description:'1. Exception occured during web services deployment. Unable to extract web services deployment data for archive auth_ejb.jar, application com.izazi/auth_app.
		 -> class java.lang.NullPointerException'.
		SDA : name 'auth_app', vendor 'com.izazi', location 'localhost', version '2009.05.07.14.36.09', software type ('J2EE', sub type ''), csn component '', dependencies :[none]

~~-snip~~-

I tried matching what I have with the SAP Help tutorials and cannot find anything wrong. Any ideas, anyone?

I'm using SAP Enhancement Package 1 for SAP NetWeaver Developer Studio 7.1 SP01 and the SAP Server that came with it.

Regards,

Johan

Hi Johan,

The two WebServices that we are trying to publish are:


@javax.jws.WebService(name="ReceivePPCommand", targetNamespace="http://xxx/extservices")
public interface ReceivePPCommand {

	void receiveResourcesCodesFromSAP(ResourceCodeMessage[] resourceCodes);
...

}


@Service("receivePPCommandBean")
@WebService(endpointInterface = "xxx.extservices.ReceivePPCommand", targetNamespace="http://xxx/extservices")
public class ReceivePPCommandImpl implements ReceivePPCommand {

   @Transactional(propagation = Propagation.SUPPORTS)
    public void receiveResourcesCodesFromSAP(ResourceCodeMessage[] resourceCodes) {
             ...
    }

...
}


@javax.jws.WebService(name="ReceiveSAPCommand ", targetNamespace="http://xxx/extservices")
public interface ReceiveSAPCommand {

	void receiveSAPDocumentFromSAP(SAPDocumentMessage[] sapDocumentMessage);
}


@Service("receiveSAPCommandBean")
@WebService(endpointInterface = "xxx.extservices.ReceiveSAPCommand ", targetNamespace="http://xxx/extservices")
public class ReceiveSAPCommandImpl implements ReceiveSAPCommand {
    public void receiveSAPDocumentFromSAP(SAPDocumentMessage[] sapDocumentMessageArray) {
      ...
    }
}

Do you have any idea?

Thank you very much.

Hello Johan! Hello Yulkyar!

Thank you for answer.

I am afraid we have another problem. Our application has worked fine with one WebService, but when I added a second one, the same error has came back. Both WebServices have the annotations.

Do you have any idea?

Our application uses Spring Framework and has a applicationContext-webservice.xml like this:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	  <jaxws:endpoint 
	  id="receiveSAPCommandImpl" 
	  implementor="#receiveSAPCommandBean" implementorClass="xxx.ReceiveSAPCommandImpl"

</beans>

Thank you in advance.

Hello,

The JAX-WS specification does not requirire to provide values for any of the @WebService annotation's properties

but for the SAP implementation it is strongly recommended to provide as much information as you can like:

name, targetNamespace, serviceName, wsdlLocation, portName.

Sorry for my delayed answer!

Best Regards,

Yulkyar

Hi,

I am happy to report that I've found out how to make this work. It seems that NetWeaver requires the @WebService annotation on the implementation class as well as on the endpoint interface class. I don't believe the specification demands it, however. So unless I'm mistaken, NetWeaver is more demanding than the spec. Be that as it may, now I can at least move on.

Johan

Hi Johan,

To be able to resolve your issue, we'd need to know more about the exception.

Could you please send the stack trace of the deployment exception?

You can find it in defaultTraces of SAP NetWeaver AS in a location similar to C:\usr\sap\<your_server_instance_name>\J<intstance_number>\j2ee\cluster\serverX\log.

Or you can just send me the application ear , if you can't find the stack trace.

Best Regards,

Yulkyar
