Christine Chen commented on AXIS-2386:
--------------------------------------
This problem started to manifest after I switched the style (-y) from RPC to
WRAPPED when running java2wsdl (Axis 1.4) against my Interface/Impl classes.
My tester classes contain a single method with 2 INOUT params of Holder types:
public void listContexts( ArrayOfStringHolder Contexts, ArrayOfDummyHolder
Dummys);
The wsdl generated has the correct complex type definition for ArrayOfDummy,
but instead of providing a definition for ArrayOfString, it just has string.
After debugging a bit, the problem seems to be with
axis.description.JavaServiceDesc::getTypeQName(), the javaClass being passed in
is "[Ljava.lang.String". Because I used WRAPPED style, it will go to:
typeQName = tm.getTypeQNameExact(javaClass);
if (typeQName == null && javaClass.isArray()) {
typeQName = tm.getTypeQName(javaClass.getComponentType());
}
The first line returns null because "[Ljava.lang.String" is not in the
typemappings (which I think do not contain any array types). Realising the
class is an array type, it will try to look up the QName for the component
type. which is string. Thus getTypeQName() returns 'string' as the QName for
my ArrayOfStringHolder type.
In the RPC style case, it will just call the following and return null.
if (style == Style.RPC) {
typeQName = tm.getTypeQName(javaClass);
}
Looks to me a paramDesc with null QName will prompt java2wsdl to generate a
complex type as expected.
For my case, perhaps the fix can be put in
axis.description.JavaServiceDesc::createOperationForMethod():
Class heldClass = JavaUtils.getHolderValueType(type);
System.out.println("heldClass: " + heldClass.getName());
if (heldClass != null) {
paramDesc.setMode(ParameterDesc.INOUT);
QName qname = getTypeQName(heldClass); ....
if the class was a Holder type, call some overloaded class of getTypeQName()
that does not look up the QName for the array's component type.
For now, I'm thinking of wrapping String inside a class, say MyString, and
declare a holder with MyString[] to work around the problem until the bug is
fixed.

> Project: Apache Axis
> Issue Type: Bug
> Components: WSDL processing
> Affects Versions: 1.2.1, 1.3
> Environment: Linux 2.4.26, java version "1.5.0_04", Tomcat 5.5
> Reporter: Eric Webster
> Priority: Minor
> Attachments: DataSet.wsdl, IncorrectDataSet.wsdl

> Java2WSDL changes type double array into a single double.
> This happens when you run Java2WSDL manually on the command line or when a
> wsdl file is generated from a service_name?wsdl url.
> Currently to fix this I just manually edit the generated WSDL file and
> distrobute that.
> The Java code originally came from a hand made WSDL file. WSDL2Java was used
> to generate the Java code. The section that is affected by this problem is
> the 'ValueVector' complexType which contains and element 'values' which is an
> array of doubles. After converting to Java and then back to WSDL 'values'
> becomes a single double.
> Here is the original WSDL file.
