how to implement custom schema ?

hi, i m practicing with nuxeo sdk and try to register a new schema like explained here http://doc.nuxeo.com/display/NXDOC/Document+types.

Unfortunatly, each time, i encounter the following error :

ERROR [org.nuxeo.ecm.core.schema.XSDLoader] FatalError: Premature end of file.
ERROR [org.nuxeo.ecm.core.schema.TypeService] org.xml.sax.SAXParseException: Premature end of file.

and the schema file became totaly empty.

Did i miss something ?

Here's the last try :

– sample.xsd

&lt;?xml version=&quot;1.0&quot;?&gt;
&lt;xs:schema xmlns:xs=&quot;http://www.w3.org/2001/XMLSchema&quot;
    targetNamespace=&quot;http://project.nuxeo.org/sample/schemas/sample/&quot;&gt;
  &lt;xs:element name=&quot;sample1&quot; type=&quot;xs:string&quot;/&gt;
  &lt;xs:element name=&quot;sample2&quot; type=&quot;xs:string&quot;/&gt;
&lt;/schema&gt;

–contrib.xml

&lt;?xml version=&quot;1.0&quot;?&gt;
&lt;component name=&quot;org.nuxeo.sample.CustomType&quot; version=&quot;1.0&quot;&gt;

   &lt;implementation class=&quot;org.nuxeo.sample.CustomType&quot; /&gt;

  &lt;extension target=&quot;org.nuxeo.ecm.core.schema.TypeService&quot; point=&quot;schema&quot;&gt;
    &lt;schema name=&quot;sample&quot; src=&quot;schemas/sample.xsd&quot; prefix=&quot;smpi&quot; /&gt;
  &lt;/extension&gt;
&lt;/component&gt;

Did you see your <xs:schema> item is not closed ?

jeremie

no, but i guess it's closed by </schema><br /> <xs:schema…..>….</schema>

This is invalid XML. Please use a XML editor and validator to write XML, don't write it by hand.

ANSWERS

You need to close the tag with the namespace prefix as well as schema as bjalon pointed out. For example

<?xml version="1.0"?>
<xs:schema targetNamespace="http://www.nuxeo.org/dam/schemas/dam/"
  xmlns:xs="http://www.w3.org/2001/XMLSchema" 
  xmlns:nxs="http://www.nuxeo.org/dam/schemas/dam/">
  <xs:element name="client" type="xs:string" />
  <xs:element name="brandMake" type="xs:string" />
  <xs:element name="productModel" type="xs:string" />
</xs:schema>

thank you, so i just closed the schema like you did, double check the file…and still have the same error.

Then your file is still not valid XML. We can't help you without seeing the exact file (use pastebin.com for instance to show it to us), and anyway you should be able check by yourself that the XML is valid or not, there are many many tools to do it.

Finally, i should have checked the file one more time. it's working now with the closing </xs:schema>.
