XSD indent serialization using JDK 1.5 [message #66431] Wed, 08 March 2006 19:42 Go to next message

When you are using JDK 1.5 (a.k.a. 5.0) and programmatically construct a
schema, it is serialized without any indentation. This seems to be due
entirely to the version of JDK used when running the application. Works
fine with JDK 1.4.x.

I expect this is due to Sun bundling a different XML parser in JDK 1.5. Are
there any magical settings for resource save that overcome this problem?
Suggested workaround to customize the resource impl for XSD model?

Thanks,
Dave Carlson

Dave,

We do the following:

public class DefaultJAXPConfiguration implements JAXPConfiguration
{
public Transformer createTransformer(String encoding) throws
TransformerException
{
TransformerFactory transformerFactory =
TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();

transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");

// Unless a width is set, there will be only line breaks but no
indentation.
// The IBM JDK and the Sun JDK don't agree on the property name,
// so we set them both.
//

transformer.setOutputProperty("{http://xml.apache.org/xalan}indent-amount",
"2");

transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount",
"2");
if (encoding != null)
{
transformer.setOutputProperty(OutputKeys.ENCODING, encoding);
}
return transformer;
}

So you could override this and use the XSDResourceImpl.XSD_JAXP_CONFIG
option to pass that in during save. If there's another magic property
value to add to the list, we can do that too. Please let me know how
you solve this...

(You'd think something like specifying the indentation would be trivial,
but apparently not. But then, you'd think determining the encoding of
an input stream would be pretty basic as well, but that took years to
get right.)

Thanks, Ed. A bit of Googling found that this is a known bug in Sun's =
JDK:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=3D6296446

Unfortunately, it's fixed in 5.0u6(b07) and the current release from Sun =
is 5.0u6(b05). Anyone know if/where I can download a newer build?

The workaround noted in this bug requires wrapping the output stream. =
Ed, is that possible to do easily with the XSD resource writer?

Dave,

You can use XSDResourceImpl.save(Writer, Map) so you can pass in a
wrapped stream if necessary.

Sorry to keep bugging you Ed, but one more question...

What is the best way to override a resource factory that is contributed =
by another plugin, in this case override the XSDResourceFactoryImpl? =
The default XSD factory is registered via extension point, as follows. =
If I add a similar exention point in my plugin for the same file =
extension but a different factory, how does EMF choose among the =
alternatives? I assume that I need to register my override factory via =
code in the plugin activator, which will (??) take priority over the =
default factory registered via extension point.

<extension point=3D"org.eclipse.emf.ecore.extension_parser">
<parser type=3D"xsd" =
class=3D"org.eclipse.xsd.util.XSDResourceFactoryImpl" />
</extension>

Thanks!
Dave

Ed,=20
I have a solution working under JDK 5.0u6 (the current release from =
Sun). Two changes are necessary
- add the Xerces specific "indent-number" to the JAXP transformation =
factory
transformerFactory.setAttribute("indent-number", new Integer(2));

- use a Writer instead of an OutputStream

I had been using Resource.save(options), but that uses an outputstream. =
So I wrote a simple utility class with a static helper. I asked about =
overriding the XSDResourceFactoryImpl, but no longer need to do that. =
But still interested in the best practice for this.

My solution looks like this:

public class XSDResourceUtil {

public static void save(XSDSchema schema, URI fileURI, ResourceSet =
resourceSet)
throws IOException {
XSDResourceImpl resource =3D new XSDResourceImpl(fileURI);
resource.getContents().add(schema);
resourceSet.getResources().add(resource);

URIConverter uriConverter =3D resourceSet.getURIConverter();
OutputStream outputStream =3D =
uriConverter.createOutputStream(fileURI);
Writer writer =3D new OutputStreamWriter(outputStream, "utf-8");

Map options =3D new HashMap();
options.put(XSDResourceImpl.XSD_JAXP_CONFIG, new =
XercesJAXPConfiguration());
try {
resource.save(writer, options);
} finally {
writer.close();
}
}


private static class XercesJAXPConfiguration extends =
DefaultJAXPConfiguration {

public XercesJAXPConfiguration() {
super();
}

public Transformer createTransformer(String encoding) throws =
TransformerException {
TransformerFactory transformerFactory =3D =
TransformerFactory.newInstance();
=20
// workaround for JDK 1.5.0u6 and before
transformerFactory.setAttribute("indent-number", new Integer(2));
=20
Transformer transformer =3D transformerFactory.newTransformer();

transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");

// Unless a width is set, there will be only line breaks but no =
indentation.
// The IBM JDK and the Sun JDK don't agree on the property name,
// so we set them both.
//
=
transformer.setOutputProperty("{http://xml.apache.org/xalan}indent-amount=
", "2");
=
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount"=
, "2");
if (encoding !=3D null) {
transformer.setOutputProperty(OutputKeys.ENCODING, encoding);
}
return transformer;
}

}
}

Dave,

There can only be one global registration, but you can make a local
registration in any ResourceSet via getResourceFactoryRegistry().

Dave,

XSDResourceImpl has this verison of save already:

public final void save(Writer writer, Map options) throws IOException

Wouldn't that work?

Yes, except that in my code it is usually most convenient to call:

resource.save(options);

This method uses the resource URI to write the file, but it always uses =

Dave,

XSDResourceImpl has this verison of save already:

public final void save(Writer writer, Map options) throws =
IOException

Wouldn't that work?

Dave,

The URI converter simply opens a stream so if you want to open the
stream some other way, that's fine; or you can always call the URI
converter directly to open the stream. In EMF 2.2, we've introduced
URIConverter.ReadonableInputStream/WriteableOutputStream to allow a
wrapped reader or writer to be passed as an input or output stream using
the existing APIs (which we would not consider changing) and these may
be unwrapped by the resource implementation (as the resources in the XMI
plugin do) to access the reader or writer directly.

Dave,

We do the following:

public class DefaultJAXPConfiguration implements JAXPConfiguration
{
public Transformer createTransformer(String encoding) throws
TransformerException
{
TransformerFactory transformerFactory =
TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();

transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");

// Unless a width is set, there will be only line breaks but no
indentation.
// The IBM JDK and the Sun JDK don't agree on the property name,
// so we set them both.
//

transformer.setOutputProperty("{http://xml.apache.org/xalan}indent-amount",
"2");

transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount",
"2");
if (encoding != null)
{
transformer.setOutputProperty(OutputKeys.ENCODING, encoding);
}
return transformer;
}

So you could override this and use the XSDResourceImpl.XSD_JAXP_CONFIG
option to pass that in during save. If there's another magic property
value to add to the list, we can do that too. Please let me know how
you solve this...

(You'd think something like specifying the indentation would be trivial,
but apparently not. But then, you'd think determining the encoding of
an input stream would be pretty basic as well, but that took years to
get right.)

Dave,

You can use XSDResourceImpl.save(Writer, Map) so you can pass in a
wrapped stream if necessary.

Sorry to keep bugging you Ed, but one more question...

What is the best way to override a resource factory that is contributed =
by another plugin, in this case override the XSDResourceFactoryImpl? =
The default XSD factory is registered via extension point, as follows. =
If I add a similar exention point in my plugin for the same file =
extension but a different factory, how does EMF choose among the =
alternatives? I assume that I need to register my override factory via =
code in the plugin activator, which will (??) take priority over the =
default factory registered via extension point.

<extension point=3D"org.eclipse.emf.ecore.extension_parser">
<parser type=3D"xsd" =
class=3D"org.eclipse.xsd.util.XSDResourceFactoryImpl" />
</extension>

Thanks!
Dave

Ed,=20
I have a solution working under JDK 5.0u6 (the current release from =
Sun). Two changes are necessary
- add the Xerces specific "indent-number" to the JAXP transformation =
factory
transformerFactory.setAttribute("indent-number", new Integer(2));

- use a Writer instead of an OutputStream

I had been using Resource.save(options), but that uses an outputstream. =
So I wrote a simple utility class with a static helper. I asked about =
overriding the XSDResourceFactoryImpl, but no longer need to do that. =
But still interested in the best practice for this.

My solution looks like this:

public class XSDResourceUtil {

public static void save(XSDSchema schema, URI fileURI, ResourceSet =
resourceSet)
throws IOException {
XSDResourceImpl resource =3D new XSDResourceImpl(fileURI);
resource.getContents().add(schema);
resourceSet.getResources().add(resource);

URIConverter uriConverter =3D resourceSet.getURIConverter();
OutputStream outputStream =3D =
uriConverter.createOutputStream(fileURI);
Writer writer =3D new OutputStreamWriter(outputStream, "utf-8");

Map options =3D new HashMap();
options.put(XSDResourceImpl.XSD_JAXP_CONFIG, new =
XercesJAXPConfiguration());
try {
resource.save(writer, options);
} finally {
writer.close();
}
}


private static class XercesJAXPConfiguration extends =
DefaultJAXPConfiguration {

public XercesJAXPConfiguration() {
super();
}

public Transformer createTransformer(String encoding) throws =
TransformerException {
TransformerFactory transformerFactory =3D =
TransformerFactory.newInstance();
=20
// workaround for JDK 1.5.0u6 and before
transformerFactory.setAttribute("indent-number", new Integer(2));
=20
Transformer transformer =3D transformerFactory.newTransformer();

transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");

// Unless a width is set, there will be only line breaks but no =
indentation.
// The IBM JDK and the Sun JDK don't agree on the property name,
// so we set them both.
//
=
transformer.setOutputProperty("{http://xml.apache.org/xalan}indent-amount=
", "2");
=
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount"=
, "2");
if (encoding !=3D null) {
transformer.setOutputProperty(OutputKeys.ENCODING, encoding);
}
return transformer;
}

}
}

Dave,

There can only be one global registration, but you can make a local
registration in any ResourceSet via getResourceFactoryRegistry().

Dave,

XSDResourceImpl has this verison of save already:

public final void save(Writer writer, Map options) throws IOException

Wouldn't that work?

Yes, except that in my code it is usually most convenient to call:

resource.save(options);

This method uses the resource URI to write the file, but it always uses =
an OutputStream. I need to study exactly what the URIConverter does on =

Dave,

The URI converter simply opens a stream so if you want to open the
stream some other way, that's fine; or you can always call the URI
converter directly to open the stream. In EMF 2.2, we've introduced
URIConverter.ReadonableInputStream/WriteableOutputStream to allow a
wrapped reader or writer to be passed as an input or output stream using
the existing APIs (which we would not consider changing) and these may
be unwrapped by the resource implementation (as the resources in the XMI
plugin do) to access the reader or writer directly.
