Hello,
I am currently trying to use the xsd API with DOM to generate XML files
which do not only contain the schema element.Is it possible to use these
the xsd API and the DOM API together in the same Java Implementation? if
not,how do i go about this situation?
Thank you.

HT,
When you call setElement with an element you constructed, it builds a
model to reflects exactly what's in that element and it discards all the
other information you might have set up that does not reflect what's in
the element. So your invalid blank element wipes out all the other
settings you did. If you are going to create a valid element manually,
you need to make sure to use createElementNS to give it the right
namespace and you'll need to create an xmlns declaration for that
namespace.
In this scenario, you should have done something like this:
Document document;
XSDSchema xsdSchema = XSDFactory.eINSTANCE.createXSDSchema();
xsdSchema.setDocument(document);
xsdSchema.setTargetNamespace("http://www.eclipse.org/xsd/examples/createxsd");
java.util.Map qNamePrefixToNamespaceMap =
xsdSchema.getQNamePrefixToNamespaceMap();
qNamePrefixToNamespaceMap.put(xsdSchema.getSchemaForSchemaQN amePrefix(),
XSDConstants.SCHEMA_FOR_SCHEMA_URI_2001);
qNamePrefixToNamespaceMap.put("createxsd",
xsdSchema.getTargetNamespace());
xsdSchema.updateElement();
I.e., give the schema the document you want it to use to create elements
and let it do all the work of creating the DOM. Failing that, create a
correct DOM, set it to the schema, and then do other settings, which
will write through to update the DOM. (I would generally avoid using
the null prefix for the schema for schema namespace, since that makes
the null namespace inaccessible, if it's needed.)

Hee,
I'm not sure I understand. The XSD model uses DOM itself, so certainly
XSD and DOM can be used in the same application. The XSD model can be
used to load a .wsdl file which contains embedded schemas, but I'm not
sure if that is what you are driving at...

Hi,
How do i use xsd and dom together? i mean can i convert my XSDSchema to a
Element so i can write in into my wsdl? or when reading a wsdl using DOM ,
how do i convert the schema Element into a XSDSchema instance..
Thanks.

HT,
Have a look at org.eclipse.xsd.util.XSDPrototypicalSchema. In
particular, look at printComponent and createElement. You probably will
want to try registering the XSD resource factory to handle wsdl like this
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put
("wsdl", new XSDResourceFactoryImpl());
and then try loading a .wsdl file just as you would load a .xsd file...

xsdSchema.setTargetNamespace("http://www.eclipse.org/xsd/examples/createxsd");
java.util.Map qNamePrefixToNamespaceMap =

qNamePrefixToNamespaceMap.put("createxsd", xsdSchema.getTargetNamespace());
xsdSchema.setElement(schemaElement);
xsdSchema.updateElement();
but the output in my file is just :
<?xml version="1.0" encoding="UTF-8" ?>
<schema />
instead of using the above (writing schema directly into file ) i have :
<?xml version="1.0" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" />
why is there a difference?
the reason i want to do this is because i am using WSDL4J to create WSDLs
and schema elements can only be represented as DOM elements.
Thank you.
