    <p>We've built a webservice with Spring-WS, and are trying to access it from a C# .NET client. the service works OK with all the tests we've done from SoapUI and other java clients, but gets stuck in .NET. </p> <p>It seems this is a problem with namespaces.</p> <p>For example, this request works, when the namespace is declared only in the envelope tag, and no element has namespace or prefix in it:</p> <pre><code>&lt;soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns="http://mycompany.org/schemas"&gt; &lt;soapenv:Header/&gt; &lt;soapenv:Body&gt; &lt;authenticationRequest&gt; &lt;username&gt;user&lt;/username&gt; &lt;password&gt;password&lt;/password&gt; &lt;/authenticationRequest&gt; &lt;/soapenv:Body&gt; &lt;/soapenv:Envelope&gt; </code></pre> <p>However, this seemingly equivalent request does NOT work:</p> <pre><code>&lt;soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns="http://mycompany.org/schemas"&gt; &lt;soapenv:Header/&gt; &lt;soapenv:Body&gt; &lt;authenticationRequest xmlns="http://mycompany.org/schemas"&gt; &lt;username&gt;user&lt;/username&gt; &lt;password&gt;password&lt;/password&gt; &lt;/authenticationRequest&gt; &lt;/soapenv:Body&gt; &lt;/soapenv:Envelope&gt; </code></pre> <p>Notice that in this case, the namespace is declared again in authenticationRequest element. The error given is that the request does not validate against the XML schema, complaining that the 'username' element is not defined. </p> <p>Unfortunately, when adding a service reference (and also a web reference) in .NET, the code generated by wsdl.exe always creates the request in the second case.</p> <p>Could someone, please, explain why these two pieces of XML are not equivalent, and how we could, in the C# client...<br> - remove the second namespace declaration?<br> - or add a namespace prefix to every element in the request?<br> - or add a namespace declaration without prefix to each element? </p> <p>We've been trying for hours :(</p> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
