Generate XSD from Java WITH documentation - xsd

I created an XSD schema and have put in some documentation via the tag.
from the XSD i generated Java classes using Jaxb (from within eclipse - jdk1.6)
i now plan to use my java classes as "source" and modify them as per requirements that come up
I will generate XSD back from modified Java classes to keep the XSD in-sync.
in this process any "documentation" on the XSD gets lost. (i.e. when i generate it from Java). Is there some way to get around this? Thanks.

JAXB bindings ignore attribute on generating JAXB classes

I have a schema (.xsd) and on generation using xjc would like to ignore some attributes being generated in the JAXB classes.
I can remove them manually once generated, but every time when schema changes, it is quite a manual task to remove from the generated class. Is there a way to achieve this using the JAXB bindings file or JAXB2 basics plugin ?

Generate DDIC structure from XSD?

I have a number of XSDs that are part of the enterprise definitions for several services at the client.
I would like to be able to take a single XSD and generate a DDIC structure from it (without the use of PI!)
Seeing as you can generate proxies directly from a WSDL, and this also generates structures and data elements from the XSD definitions inside the WSDL, there is obviously already ABAP code that does this.
But do you know what classes/function modules to use to achieve this? Perhaps there is a convenient utility function or class method that takes the XSD as input and generates the relevant DDIC objects?
Some background on why I need this:
Some of the services include variable sections that include a piece of XML containing the data for one of the enterprise XSD entities; I am hoping to have a DDIC representation of these, which I can fill at runtime and then convert to XML to include in the message.
There is a program on the system called SPROX_XSD2PROXY with which you can upload one or more XSD files which will generate proxy objects for you.
You also end up with a service consumer with a corresponding class and what looks like a dummy operation.
The program is fairly short; it uploads the files(s) to an XSTRING, then converts the XSD(s) to WSDL(s) and finally the WSDL(s) to proxy objects using methods of a class called CL_PROXY_TEST_UTILS.
However, the result is satisfactory as it does give me a structure I can work with. And by examining the contents of those methods, it may be possible to build a more fine-tuned tool if I need one.

Jaxb XML binding file generator from annotations?

I am working on project in which we need get rid of all JAXB annotations for readability sake and write XML binding file only. Are there any XML binding file generator from Annotated JAXB classes to ease my task of writing binding XML ?
You can achieve this using MOXy (this is JAXB extension). Check more examples in Blaise Doughan blog: Extending JAXB - Representing Metadata as XML and Mapping Objects to Multiple XML Schemas - Weather Example.

Using JIBx to generate XSD from binding.xml

Is there a way to generate an XSD document automatically from the binding.xml used by JIBx? This is mainly to allow offline validation of the XML documents will be unmarshalled eventually.
I checked the JIBx homepage, it mentioned a tool called Schema Generator:
http://jibx.sourceforge.net/jibxtools/schema-example.html
but looks like the jibx-genschema.jar file is no longer part of the package anymore, as such I was wondering if there is any alternative
Thanks!
Here is the link to the original package.
http://mirrors.ibiblio.org/pub/mirrors/maven2/org/codehaus/xfire/jibx/genschema/jibx-genschema.jar
Schema generator main class is org.jibx.binding.Compile. It is available in jibx-bind.jar.
This jar can be added to your project with maven dependency org.jibx:jibx-bind:1.2.3 (for example).
The SchemaGen tool has been included in the jibx-tools.jar file for some time. See the JiBX Binding Generator page for instructions on running tools in the jar, just substitute the target class org.jibx.schema.generator.SchemaGen to run the schema generator.

Load XML file into object. Best method?

We are receiving an XML file from our client. I want to load the data from this file into a class, but am unsure about which way to go about it.
I have an XSD to defining what is expected in the XML file, so therefore i can easily validate the XML file.
Can i use the XSD file to load the data into a POCO, using some sort of serialization?
The other way i was thinking was to load the xml into a XMLDocument and use XPath to populate each property in my class.
Cheers for any advice
Depending on how complex the XSD is, you have a couple of options:
Use xsd.exe to generate C# classes which can be used in conjunction with the XmlSerializer.
Use svcutil.exe with the /dconly argument to generate DataContract-attributed types appropriate for use with the DataContractSerializer.
