Re: Exception with JaxWsClientProxy when invoking a method with
complex objects
Hi,
Many thanks for your answer. I have tried with 2.2.1-SNAPSHOT but it didn't
work either. However, I have the exception cause now. That this make sense
to anyone? How can I avoid this NPE?

Bug

Re: Exception with JaxWsClientProxy when invoking a method with
complex objects
Posted by Bruno Aranda <br...@gmail.com>.
Hi,
I couldn't investigate this issue until today, but I found the reason
to this problem.
Basically I am generating my classes from the WSDL using the
cxf-codegen-plugin. In my jaxb bindings I was using <xjc:simple> to
generate nice method names for the generated classes.
However, changing the methods names did affect the ability to choose
the correct accessors in the org.apache.cxf.jaxb.JAXBUtils class.
For example, I had a list of a complex some object called "dbRef":
<xs:complexType name="dbRefListRequest">
<xs:sequence>
<xs:element name="dbRefList" type="psq:dbRefList"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="dbRefList">
<xs:sequence>
<xs:element maxOccurs="unbounded" name="dbRef"
type="psq:dbRef"/>
</xs:sequence>
</xs:complexType>
The generator was creating a class that used this list, where the
accessor methods had the funny name "getDbReves" or "setDbReves" (of
couse, the plural of dbRef is dbReves? :))
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "getByInteractionList", propOrder = {
"dbReves",
"infoRequest"
})
public class GetByInteractionList {
@XmlElement(name="dbRef", required = true)
protected List<DbRef> dbReves;
...
And then those accessors were not found.
Removing the <xjc:simple> fixes the issue, but I have lost the "nice"
plurals, which I can live with.
Bug or feature?
Thanks,
Bruno

Re: Exception with JaxWsClientProxy when invoking a method with
complex objects
Posted by Bruno Aranda <br...@gmail.com>.
Hi,
Yes, other methods like the one you propose works. I have an very similar
method that instead of the list of DbRef accepts just a DbRef and that one
works. I will try to debug it further and to create a simple test case if I
can...
Thanks,
Bruno

Re: Exception with JaxWsClientProxy when invoking a method with complex objects
Posted by Daniel Kulp <dk...@apache.org>.
The list should work fine as long as the thing it is a list of also works
fine. Are there any annotations on DbRef? The issue really comes down to
why is the typeQName null in this case. It should definitely not be.
Does a method like:
int testDbRef(DbRef ref)
work?
Any chance you could create a small sample and attach to a JIRA?

Re: Exception with JaxWsClientProxy when invoking a method with
complex objects
Posted by Bruno Aranda <br...@gmail.com>.
Hi, sorry to write again, but I have more details about the problem:
The method signature:
QueryResponse getByInteractorList( List<DbRef> dbRef, RequestInfo
infoRequest, String operand );
QueryResponse, DbRef and RequestInfo are complex objects. The problem seems
to be related to the use of the List<DbRef> parameter. In the line where the
exception below happens, the first item of an array called getMethods[] is
being invoked (getMethods[0]). However, this array does not seem anything
set in position 0 (but there are values for getMethods[1] and
getMethods[2]). So getMethods[0] returns null, hence the
NullPointerException.
I see that in org.apache.cxf.jaxws.interceptors.WrapperClassOutInterceptor
(line 161) the element type is set to null because the message part does not
have a typeQName. This null is the one causing the NPE later on,
Any ideas? Aren't List object allowed as parameters?
Thank you,
Bruno
