Error calling listener method in cxfbc provider endpoint

ngaurav Nov 26, 2010 6:53 AM

Hi,

I am trying to create a cxfbc provider endpoint to post a soap message to a Web Service. I am using apache-servicemix-4.3.0-fuse-00-00 version of servicemix. Here is the endpoint:

<constructor-arg value="$" />

cxf.xml:

<http:conduit name="ServicePort.http-conduit">

<http:tlsClientParameters>

<sec:trustManagers>

<sec:keyStore type="JKS" password="******" resource="classpath:keystores/keystore.jks" />

</sec:trustManagers>

<sec:cipherSuitesFilter>

<sec:include>.EXPORT.</sec:include>

<sec:include>.EXPORT1024.</sec:include>

<sec:include>.WITHDES_.</sec:include>

<sec:include>.WITHNULL_.</sec:include>

<sec:exclude>.DHanon_.(EndpointTracker.java:77)[90:servicemix-common:2010.02.0.fuse-00-00]

at org.apache.servicemix.common.osgi.EndpointTracker.register(EndpointTracker.java:58)[90:servicemix-common:2010.02.0.fuse-00-00]

... 38 more

Caused by: java.lang.NullPointerException

at org.apache.servicemix.cxfbc.CxfBcProvider.validate(CxfBcProvider.java:418)[131:servicemix-cxf-bc:2010.02.0.fuse-00-00]

Can anyone please help me understand what this error means and how to get rid of it?

Thanks,

Gaurav

Hi,

Given the root exception

Caused by: java.lang.NullPointerException
at org.apache.servicemix.cxfbc.CxfBcProvider.validate(CxfBcProvider.java:418)

CxfBcProvider.java:418 is

definition = getBus().getExtension(WSDLManager.class)
.getDefinition(wsdl.getURL());

I think somehow the wsdl you specified for cxfbc:provider is null, maybe caused by incorrect path.

Hi Freeman,
I tried giving a fake location for wsdl and at that time, it throws FileNotFoundException. It means that there is something wrong while validating the wsdl. I added the following in cxfbc endpoint xml:

Then I started getting following error:

My wsdl has got the element "definitions" with proper namespace. In wsdl, definitions element starts like this:

Can you please suggest any solution?

ffang Nov 26, 2010 10:03 AM (in response to ngaurav)

Hi,

You can't do

in your spring bean, as wsdl file isn't a spring bean configuration file.

If you wanna see if this wsdl is valid, you can use wsdl2java tool shipped with cxf,
wsdl2java your_wsdl_file

This can give you more info about if the wsdl is valid or not.

ngaurav Nov 29, 2010 10:47 AM (in response to ffang)

Hi Freeman,
I tried wsdl2java and it did not throw any error. So wsdl seems to be valid. We were able to get this endpoint deployed successfully when we added those certificates in jre folder and we did not have "providedBus" configuration in the endpoint. So it must have something to do with that. I removed the import statement for wsdl and I am again getting the same NullPointerException. Do you have any idea what it might be?

ngaurav Nov 30, 2010 11:32 AM (in response to ffang)

Hi Freeman,
I figured that this NullPointerException was occurring because I had not imported the cxf-extension-soap.xml. Now it is throwing me an exception saying..

Could not load keystore resource classpath:keystores/keystore.jks

I have seen your post regarding the same thing and you had suggested to create a fragment bundle having the keystore. Can you please point me to some example which describes how I can create fragment bundle using build tool as maven.

Thanks,
