Question

I am developing a webservice, it is java in the server, and must be c# in the client.
There is just one String as in parameter and as out parameter it will return an “object” with this structure:

• String codError
• String descError
• Object2[] arrayData

being “Object2” like this:

• String firstDataArray
• Int secondDataArray

I created a java client and it works flawlessly, but the c# client does not work. It says that the “EndElement” of the object was not expected (meaning the end of the object, not object2), and that it was expected a “codError” element.

The method does NOT return an array of Objects, just one Object.

I used httpanalyzer, and as well from the java client as from the c# client, the server retuns a well formed xml, and its contain is what it is supposed to be (in both clients).

I am using eclipse and axis2 for java, and visual studio 2005 and 2008 for c#.

What could be wrong?

Thanks in advance!!

Answer 1

The problem was that the auto-generated WSDL by axis and eclipse was wrong, and so, the XML sent from the server to the client was also wrong.
I think it is a common problem when creating the webservices bottom-up. It is much better create them top-down.

The XML that the server was sending to the client was something like (just the wrong part):

<descError>OK</descError>
<codError>0</codError>
<object2>
    <object2>
        <firstDataArray>John</firstDataArray>
        <secondDataArray>35</secondDataArray>
    </object2>
    <object2>
        <firstDataArray>Andrew</firstDataArray>
        <secondDataArray>76</secondDataArray>
    </object2>
    <object2>
        <firstDataArray>Walter</firstDataArray>
        <secondDataArray>23</secondDataArray>
    </object2>
</object2>

There is a “object2” tag there, that should not be.
It works creating a client for java using eclipse, but it does not in c#

I just made the same web service using the top-down implementation and it works great now!!

Thaks a lot to everyone!!
