RE: [Axis2] Soap Encoding support with ADB
+1 on Glen's -1 of using a whole new set of types to support SOAP
encoding. A String must map to a soapenc:string and a Array[] must map
to a SOAP encoded array.
I would also argue for "full" multiref support, as servers will be
sending this back to Axis2 clients, right?
Amila, please feel free to use the Axis 1.x code base as a reference for
how to do any of this. Please also feel free to NOT to duplicate the
Array serialization/deserialization bugs. :-)

Yes. But - I was incorrect about the MUST above! My hands were typing
a little ahead of my brain there. :) Multirefs are not in fact
*required* by SOAP 1.1 section 5, but some implementations (Axis 1.X
included) will by default serialize all complex objects as multirefs
since it speeds writing (if you don't do it that way you have to walk
the entire data graph to see what objects are referred to multiple times
before serializing).

Again, my bad - we're not forced to do so, so it's ok for us not to, as
long as we accept that we're not going to be able to do real graphs. If
no one wants this particular functionality, I'm fine with punting on it.
Your idea about parsing the XML to remove the hrefs and generate a
larger "virtual" expanded document on the reading side should work fine,
although it will potentially cause repeated data if a multiref is used
many times. Probably not a big deal. I'll respond to the rest of your
other note in another message.
Thanks,

So you basically telling
<s:element name="TestSoapElement2">
>> <s:complexType>
>> <s:sequence>
>> <s:element name="param1" type="s:string"/>
>> <s:element name="param2" type="soapenc:Array"/>
>> </s:sequence>
>> </s:complexType>
>> </s:element>
use Object[] as the type of the param2 isn't it?
even in this case people people can not use int, double and they have to use
Integer Double etc..
In this case how we going to extend this to support double arrays? What I
thought
to add soapencoding.Array object as a child object and handle this in
serializing logic.
I agree that in the model I have done it is not much user friendly. But we
can extend that
to support any thing and people can do any thing with it. Sometimes this may
be important than getting
a user friendly interface with a limited functionality (Anyway it is my
personal preference).
But if we don't going to think about this I am ok to change this to Object[]
assuming
only one dimensional arrays being used.

In general, Amila, SOAP array types want to turn into language arrays,

Doubles/doubles (depending on nillable), not MyDoubleClass.

Re: [Axis2] Soap Encoding support with ADB
Posted by Amila Suriarachchi <am...@gmail.com>.
Here is the summary of this discussion.
ADB soap encoding support is to provide support for wsdls having soap
encoding schema types.
ADB supports only Single reference serialization and hence graphs with loops
can not be supported. But
multireference parsing is supported.
For a general schema with a soap:Array it generates a code with
soapencoding.Array element.
i.e for a schema like this.
<s:element name="TestSoapElement2">
> <s:complexType>
> <s:sequence>
> <s:element name="param1" type="s:string"/>
> <s:element name="param2" type="soapenc:Array"/>
> </s:sequence>
> </s:complexType>
> </s:element>
here param2 type would be a soapencoding.Array.
But for this special type of schema pattern
i.e.
<s:element name="TestSoapElement2">
> <s:complexType>
> <s:sequence>
> <s:element name="param1" type="s:string"/>
> <s:element name="param2" type="tns:ArrayOfInt"/>
> </s:sequence>
> </s:complexType>
> </s:element>
<xs:complexType name="ArrayOfInt">
<xs:complexContent mixed="false">
<xs:restriction base="q1:Array">
<xs:attribute a:arrayType="xs:int[]" ref="q1:arrayType"/>
</xs:restriction>
</xs:complexContent>
</xs:complexType>
it sets the param2 type as int[] (given type with a:arrayType attribute)
is this ok?
thanks,
Amila.

I check with the Axis 1.x generated wsdls and microsofts' interop sites
wsdls.
for axis 1.x
<complexType name="ArrayOf_xsd_string">
<complexContent>
<restriction base="soapenc:Array">
<attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:string[]"/>
</restriction>
</complexContent>
</complexType>
and for interop site
<xs:complexType name="ArrayOfInt">
<xs:complexContent mixed="false">
<xs:restriction base="q1:Array">
<xs:attribute a:arrayType="xs:int[]" ref="q1:arrayType"/>
</xs:restriction>
</xs:complexContent>
</xs:complexType>
so it is a general convention every one uses. Therefore I think adding
support for this generic convention solves our problem. And we can keep what
existing thing to support soap encoding in a generic way.
Any thoughts?

In the soap encoding schema Array is defined as a complex type. Then why it
is wrong to use it as a type?
Anyway in the article you given it has mentioned like this.
The WSDL specification requires that arrays be based on the SOAP
1.1encoding schema. It also requires that arrays use the name
ArrayOfXXX, where XXX is the type of item in the array.
Does WSDL specification say something like this? For me it is an customized
type they have come up with
to solve the problem we have. They have define some convention to determine
the array type. But I think
we need to come up with some generalized approach to support any schema.
Like I have given above.
I'll have a look at the wsdls generated by Axis 1.x with soap encoding and
the corresponding java classes generated by the wsdl2java tool.

Re: [Axis2] Soap Encoding support with ADB
Posted by Anne Thomas Manes <at...@gmail.com>.
Amila,
SOAP encoding is much more likely to be used in a code-first scenario,
but you must make sure that it also works in a WSDL-first scenario.
Regarding one of your questions, you would never see an element
defined as follows:
<s:element name="TestSoapElement2">
> <s:complexType>
> <s:sequence>
> <s:element name="param1" type="s:string"/>
> <s:element name="param2" type="soapenc:Array"/>
> </s:sequence>
> </s:complexType>
> </s:element>
First off, you would define a named complexType rather than an
element. And second, you never define an element simply as
soapenc:Array. The ComplexType would look something like this:
<s:complexType name="TestSoapType2">
<s:sequence>
<s:element name="param1" type="soapenc:string"/>
<s:element name="param2" type="tns:ArrayofString"/>
</s:sequence>
</s:complexType>
<complexType name="ArrayOfString">
<complexContent>
<restriction base="soapenc:Array">
<attribute ref="soapenc:arrayType"
wsdl:arrayType="string[]"/>
</restriction>
</complexContent>
</complexType>
Or even more likely, you wouldn't define the "TestSoapType2" type --
you would simply reference the child types in the WSDL message
description:
<w:message name="TestInput">
<w:part name="param1" type="soapenc:string"/>
<w:part name="param2" type="tns:ArrayofString"/>
</w:message>
You might find this article helpful:
http://www.developer.com/services/article.php/10928_1602051_3
You also might spend a little time playing with Axis generating some
RPC/encoded services to get a better sense of how the environment
works.

Re: [Axis2] Soap Encoding support with ADB
Posted by Amila Suriarachchi <am...@gmail.com>.
hi tom,
I went through the Axis user guide[1] and as I understood Axis 1.x has used
soap encoding in the
code first approach to support Arrays. I think this is where both you and
glen has misunderstood.
in that case if I have a class like this
public class Test {
private int[] testArray;
public void setTestArray(int[] param){
testArray = param;
}
public int[] getTestArray(){
return testArray;
}
}
in this case as Axis 1.x has done users must be given the chance to deal
with the standard types and it is
almost useless to ask to deal with a new type. Further as I guess it uses *
org.apache.axis.providers.java.RPCProvider *as in Axis2 RPCMessageReceiver.
BTW one question. Why Axis 1.x use soap encoding for this? why it simply
generate something
like this
<element name="testArray" minOccurs="0" maxOccurs="unbounded"/>
it is always better to use POX rather than encoding types isn't it?
So we won't be able to use the Axis 1.x code for this.
But In the contract first approach people always have to deal with the
generated classes. So I believe in this
case I don't think it is a problem. Here the main idea is to access a
service already deployed with soap:encoding.
So it would only be used at client side.

hi tom,
thanks you your reply. if you have already working with axis 1.x could you
please help on answering these
questions?

In axis 1.x is it use in code first or contract first (i.e. wsdl2java)
approach? Here what I am trying to do is to
use it with the wsdl2java tool. i.e with the contract first approach.
So the main question is what is the generated method signature for
<s:element name="TestSoapElement2">
> <s:complexType>
> <s:sequence>
> <s:element name="param1" type="s:string"/>
> <s:element name="param2" type="soapenc:Array"/>
> </s:sequence>
> </s:complexType>
> </s:element>
this type of element. what is the type of param2 in Axis 1.x? Here in code
generation
time I do not know the type of the array. That is why I set it as a new type
letting users to define it.

I agree. I'll add this feature as I have describe earlier.

For the moment in Axis 2 ADB is also in a very stable state. so using
already existing ADB logic
won't give any serializing de serializing issues.
