Trying the HelloWorld Web Service example and am getting an error
in the WS Explorer:
IWAB0379E Unable to open http://localhost:8080/HelloWorld/services/HelloWorld?WSDL.
IWAB0135E An unexpected error has occurred.
WSDLException
WSDLException: faultCode=OTHER_ERROR: http://localhost:8080/HelloWorld/services/HelloWorld?WSDL

And an error if trying in the browser:

Also – http://localhost:8080/HelloWorld/services in browser will show services:

Services:

* HelloWorldService [wsdl]

But clicking on the [wsdl] link results in the duplicate error.

Found codeHaus jira error that is related:

How do I get the new XFire into myeclipse as it has a fix for:
Fix for duplicate attribute in WSDL bug.

I checked and the following are the jar versions of xfire in my lib dir.

MDOT,

I apologize for the delay in responding. Thanks for tracking this issue down – if you are using MyEclipse 5.1.0 (which you are, according to your log), you already do have XFire 1.2.2 – if you still see the problem that means the issue hasn’t been fully / correctly resolved in XFire 1.2.2. I’ll look into this problem and take it up with the XFire team if necessary. Could you tell me how you generated this web service? Did you follow our tutorial? I ask because the WSDL file generated does not seem to correspond to the WSDL file I see generated in my tests.

To upgrade to a more recent version of XFire, you can go to Window > Preferences > MyEclipse > Project Capabilities > Web Services – XFire and make replace the old JARs with freshly downloaded versions. The next MyEclipse release in under a months time will include XFire 1.2.3 or 1.2.4.

Hope this helps.

[Paul Weinberger]

Brian – Yes I was following the tutorial.
Sounds like I should wait and try it again with the update next month.
Close this for now and I will wait for the update.

[Brian Fernandes]

Hi,

I’m trying to follow this up with the XFire team, apparently this might happen with some library combinations. Could you tell me what MyEcipse libraries you added to your project?

[dandubinsky]

Has anyone figured this out? I’ve been experimenting with XFire with Oracle OC4J and I get this error in OC4J 10.1.3, but it works OK in 10.1.2. In 10.1.3 it’s putting in the xmlns:xsd twice.

Hi!
I have just downloaded MyEclipse 5.5.1, and tried to create a very simple webservice (it should just say “Hi!”, and got this error:

Error de parseo XML: atributo duplicado
Lugar: http://localhost:8888/TestOc4jME/services/GreetService?wsdl
Línea 16, Columna 152:<xsd:schema xmlns:xsd=”http://www.w3.org/2001/XMLSchema&#8221; targetNamespace=”http://test&#8221; elementFormDefault=”qualified” attributeFormDefault=”qualified” xmlns:xsd=”http://www.w3.org/2001/XMLSchema”&gt;
——————————————————————————————————————————————————-^

As you can see… it is the exact same error the original poster had:
Error de parseo XML: atributo duplicado = “XML Parsing Error: duplicate attribute ” (just translate spanish to english, BTW do you know how can I force java to work in engish?)

So? what is happening? is this some kind of MyEclipse + XFire + OC4J 10.1.3.2 compatiblity failure? (Please help)

[dandubinsky]

I’ve done some research into this. It’s a problem between Oracle 10.1.3 and XFire (nothing to do with MyEclipse). It doesn’t work on a production server either. The thing is you can still invoke an XFire web service, just the wsdl generation doesn’t work. I’ve tried a bunch of different things, but so far no success. There is also a report of this issue on the XFire web site. I tried some of the solutions on there, but they didn’t work for me.

So for now, we are avoiding OC4J 10.1.3 altogether. We’ve had a bunch of other issues with it as well involving XML stuff on that server (some JAXB code we have stopped working when we deployed to 10.1.3). We also had some trouble getting EJBs projects hot redeployed in the development environment. For now we are staying with 10.1.2 and will take another look when 10.1.4 comes out.

[steppoll]

When deploying an application in the Oracle AS (10.1.3), there is a part of the deployment where you can configure the deployment plan. The last option is “Configure Class Loading”. If you click on the “Go to Task” option, it will bring you to another screen. Uncheck every option there in the table. After I did that it worked. I suppose it is just one library that conflicts, but I was to lazy to figure out which one exactly. If somebody has the time to do that then please let us know your findings.
