LinkageError when calling a cxf endpoint

garethahealy Jun 18, 2012 9:25 AM

My setup is as follows. I have 3 bundles; common, magento and images.

Images does all the work, and uses classes from the other two. When i make a webservices call which throws a soap fault i get the following exception:

Caused by: java.lang.LinkageError: javax/xml/soap/SOAPFault

I've spent the last 2 days trying to figure out whats wrong, but havent got anywhere.

1. Re: LinkageError when calling a cxf endpoint

garethahealy Jun 18, 2012 11:37 AM (in response to garethahealy)

I've tweaked the POMs so as that only magento has a requirement on CXF, but i now get a new error:

Caused by: javax.xml.ws.spi.FactoryFinder$ConfigurationError: Provider org.apache.cxf.jaxws.spi.ProviderImpl not found

From a bit of googling (here) it suggests creating the following file: /src/main/resources/META-INF/services/javax.xml.ws.spi.Provider

Which i have done, but not to any joy.

2. Re: LinkageError when calling a cxf endpoint

gertv Jun 18, 2012 3:16 PM (in response to garethahealy)

L.S.,

We did change the way these specs are being loaded to allow reusing the JRE implementation when nothing else is available, but still allow using the more advanced OSGi-aware implementations to be used as well. Though I haven't seen this exception before, there may always be a case we're not handling correctly yet.

Do you think you can create a sample project and provide us with some instructions to reproduce the issue, so we can look into this?

One more question: what platform (OS, JRE, ...) are you using?

Regards,

Gert Vanthienen

garethahealy Jun 20, 2012 4:30 AM (in response to gertv)

I found a few people saying (here) that i should do:

Thread.currentThread().setContextClassLoader(Bus.class.getClassLoader());

This stopped the above error, but is now causing another problem, in that unmarshalling now doesnt work:

Execution of JMS message listener failed.

Hi,

Did you save the oldClassloader and set the oldClassloader back after you call
Service.create..?

garethahealy Jun 20, 2012 8:21 AM (in response to ffang)

No, i wasnt. But i've changed my code so that it is. But now, i am back to square one as i am getting the linkage error again. I am not sure how to send you a mocked up project as well, because the problem only occurs when a soap fault is thrown when calling the web service, and i currently dont have an external web service i can give you access to...

Which version of Fuse ESB are you using?
Can you double check the bundle you installed if there are more than one bundle exports the package of "javax.xml.soap" ?

garethahealy Jun 21, 2012 4:01 AM (in response to njiang)

I am using: fuse-esb-7.0.0.fuse-061

And the only package that does anything SOAPy is the magento one, which has:

Import-Package =
        javax.xml.soap,
        javax.xml.ws.soap,
        org.apache.cxf
Export-Package =
        com.boohoo.magento;uses:="org.apache.cxf,javax.xml.soap,javax.xml.ws.soap"

Hi,

Could you edit
$FUSE_ESB/etc/jre.properties

comment out pacakge
javax.xml.soap, (you can just add # before this line to comment it out)

then remove $FUSE_ESB/data folder and restart fuse esb, to see if it works for you?

Or
another solution is that you revise the magento bundle OSGi metadata header a little bit, specify version 1.3 for Import-Pacakge javax.xml.soap.

garethahealy Jun 21, 2012 5:37 AM (in response to ffang)

I did as you suggested for soloution 1 (changing the jre file), which didnt work.

I also changed the import headers to: javax.xml.soap;version="1.3" which didnt work either...

Few bits more of info: v1.6.0_29 and windows 7 pro sp1 (my dev machine)

ffang Jun 21, 2012 6:26 AM (in response to garethahealy)

Hi,

There are two javax.xml.soap in jre.properties, ensure you comment out both, also ensure you remove $FUSE_ESB/data folder after change.

If it still doesn't work you do both I mentioned, I'll take a close look at the testcase you appended, could you elaborate the steps how I can reproduce the exception?

garethahealy Jun 21, 2012 6:53 AM (in response to ffang)

Yeah, i commented out both soap on lines 123 and 285. And i also deleted everything in the data folder, which caused me to the then re-add the features url and load in my bundles again, which i presume you wanted to happen.

To get my test project to work, all you need to do is change the property "image.location" to where ever you unzip the bundles to, i.e.:

<cm:property value="C:\_Code\WorkspaceTemp\_image\" name="images.location"/>

The above property is in the 'boohoo-esb-products-images-into-cms-fuse' bundle context file.

The '_image' folder contains an image, which will be read in, parsed, sent over active mq and then a SOAPFault will be thrown. I've supplied a features file as well, so you can just do:

features:addurl mvn:com.boohoo/boohoo-esb-features-fuse/1.0-SNAPSHOT/xml/features
features:install boohoo-esb-products-into-cms-fuse

Cheers.

ffang Jun 25, 2012 3:45 AM (in response to garethahealy)

Hi,

Took a close look at your testcase.

The testcase actually has nothing to do with cxf inspire me.

So what you need do is
1. don't change the jre.properties, if you did rollback it first
2. edit magento-soap-api-fuse/pom.xml, add javax.xml.soap;version="[0, 0]", for Import-Package

then your testcase works for me, I can see output like
