    <p>after generating some classes from a xsd file, the classes are faulty. a @xmlElementRef is used with required="false" and that attribute is not allowed. My .xsd I'm using:</p> <pre><code>&lt;xs:schema xmlns:ns="http://shop.pau.softm.com/xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" targetNamespace="http://shop.pau.softm.com/xsd"&gt;

What do i have to change in the xsd? The xsd is an extract from a wsdl and i want to use the resulting classes to call a webservice.</p> <p>siegfried</p> <p>OK, some mor infos here, can't answer my own question...</p> <p>I'm working with STS and Java6. in my build.xml is coded</p> <pre><code>&lt;!-- JAXB--&gt; &lt;taskdef name="xjc" classname="com.sun.tools.xjc.XJCTask"&gt; &lt;classpath&gt; &lt;fileset dir="lib/ct" includes="*.jar" /&gt; &lt;/classpath&gt; &lt;/taskdef&gt; &lt;target name="gen.java" description="Generates the JAXB business objects"&gt; &lt;xjc destdir="src/gen" extension="true"&gt; &lt;schema dir="conf/webapp/WEB-INF/schema" includes="*.xsd" /&gt; &lt;binding dir="resources" includes="*.xjb" /&gt; &lt;/xjc&gt; &lt;/target&gt; </code></pre> <p>My binding.xjb looks like</p> <pre><code>&lt;jxb:bindings version="1.0" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" jxb:extensionBindingPrefixes="xjc"&gt; &lt;jxb:bindings schemaLocation="../conf/webapp/WEB-INF/schema/wsinapa.xsd" node="/s:schema"&gt; &lt;jxb:bindings node="/s:schema/s:element[@name='AccountStatus']"&gt; &lt;jxb:class name="AccountStatusRequest"/&gt; &lt;/jxb:bindings&gt; &lt;/jxb:bindings&gt; </code></pre> <p></p> <p>in the src dir are 2 .xsd that should be compiled. One of them compiled without errors, the other not. Both where extracted from wsdl files.</p> <p>cheers</p> <p>Siegfried</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
