[Johan Kenens]

Hi,

After going through the WS example, it was time for the real work. I took one of my classes and converted it to a web service. To my surprise I got this working in a couple of minutes “with the web services explorer”. Great! When I exported the WSDL to the workbench is noticed that it was not validated against the schema. I got 2 validation errors, one for my return type which is an ArrayList of a user defined type “StatistiekRecord” and one for the exception thrown by the web method (see bold in the WSDL).

The Client throws the XFire exception:

Exception in thread “main” org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Couldn’t instantiate class. com.brabo.tests.StatistiekRecord
org.codehaus.xfire.fault.XFireFault: Couldn’t instantiate class. com.brabo.tests.StatistiekRecord

…and I don’t have a clue on where to start looking.

Any help appreciated

Johan

Johan,
Is your:

com.brabo.tests.StatistiekRecord

class getting deployed with the webservice as part of the project or is this from another project or library that could possibly not be getting deployed correctly?

[Johan Kenens]

You are right. That class was copied to the wrong package. The client is now OK.
Although everything is working OK now the WSDL validation error is still bothering me.
Any idea? In the web services explorer I also get an idication that there is something wrong with the WSDL
Is this an XFire issue?

You are great help!

Johan

Here is what I get after opening the WSDL:

IWAB0380E Errors were encountered while validating XML schemas.
XSD: Type reference ‘http://werkdruk.brabo#WerkDrukException&#8217; is unresolved
IWAB0381I http://localhost:8080/WerkDrukService/services/WerkDrukService?WSDL was successfully opened.

Here is the WSDL again with validation error in Bold

Some additional info

Validation error 1
——————–
src-resolve.4.2: Error resolving component ‘ns1:ArrayOfStatistiekRecord’. It was detected that ‘ns1:ArrayOfStatistiekRecord’ is in namespace ‘http://util.brabo&#8217;, but components from this namespace are not referenceable from schema document ‘file:///C:/MyEclipseWorkspace/WerkDrukService/temp.wsdl’. If this is the incorrect namespace, perhaps the prefix of ‘ns1:ArrayOfStatistiekRecord’ needs to be changed. If this is the correct namespace, then an appropriate ‘import’ tag should be added to ‘file:///C:/MyEclipseWorkspace/WerkDrukService/temp.wsdl’.

Validation error 2
——————–
src-resolve.4.2: Error resolving component ‘ns2:WerkDrukException’. It was detected that ‘ns2:WerkDrukException’ is in namespace ‘http://werkdruk.brabo&#8217;, but components from this namespace are not referenceable from schema document ‘file:///C:/MyEclipseWorkspace/WerkDrukService/temp.wsdl’. If this is the incorrect namespace, perhaps the prefix of ‘ns2:WerkDrukException’ needs to be changed. If this is the correct namespace, then an appropriate ‘import’ tag should be added to ‘file:///C:/MyEclipseWorkspace/WerkDrukService/temp.wsdl’.

Thanks

Johan,
I got the same two error markers when I used your WSDL file. I also pasted the example into a few other XML editors from other products and got errors as well, except different errors… I don’t think this file is valid for whatever quirky reason (XML baffles me sometimes).

[Johan Kenens]

This is the WSDL generated by Xfire! Should I ask them for an explanation?

Johan

[Riyad Kalla]

Well that’s not good… have you checked the bug tracker for anyone else complaining about a similar issue?

[qnob]

Hi! I got the same Fault with the message “Couldn’t instantiate class…” because of missing default constructor.

[Riyad Kalla]

Ahh, good find gnob, thanks for posting.

[qnob]

Never mind! I thank you for your support and for your nice plugin collection.
