How to create JSF application from xsd files?

Question

Hi,
We have many xsd files describing xml's which we are supposed to send to web services. Application which we are creating should allow user to fill xml documents with data and then we should send those xml files to some web service. We want to automatize as much as possible the process of application creation to avoid possible errors and to minimize our efforts (there are plenty of quite complex xsd files).
Our first approach was: we used Oracle JSXB to generate java classes basing on xsd files (using JDeveloper 10.1.3.2.0.4066). Then we tried to generate DataControls, but this action fails with following error:
Window title: Error in init bean
Message: Could not complete initbean because it would result in an invalid document
Details: oracle.bali.xml.model.XmlInvalidOnCommitException: SEVERE: Wartość atrybutu Name nie jest typu ID (Value of Name attribute is not of ID type)
Wartość musi być następującego typu: (Value must be of following type)
Nazwa typu: ID (Type name)
Typ pierwotny: string (Primitive type)
Z następującymi więzami: (With following constraints)
zgodne z wzorcem: [\i-[:]][\c-[:]]* (Compliant with template)
[ node = Name ]
<JavaBean version="10.1.3.40.66" id="XSLStylesheet" BeanClass="oracle.xml.xslt.XSLStylesheet" Package="oracle.xml.xslt" isJavaBased="true">
<Attribute Name="classMethodParams" IsUpdateable="0" Type="java.util.Hashtable" />
We tried Sun implementation fo JAXB - it generated different java classes (with annotation mechanism). Creation of DataControls using those classes was successful. Then we created simple JSF page and tried to put those DataControls on it in order to let the user fill it with data. The thing is that those controls are read only as there is no row created in those DC. We can't create any row in those DC as there are only 'commit' and 'rollback' operations. When we try to call 'CreateInsert' operation on child elements of those DC we get error in JDeveloper log window:
2007-05-29 10:08:46 oracle.adf.controller.faces.lifecycle.FacesPageLifecycle addMessage
WARNING: JBO-29000: DataControl:createRowData
2007-05-29 10:08:46 oracle.adf.controller.faces.lifecycle.FacesPageLifecycle addMessage
WARNING: DataControl:createRowData
new row is not created and controls are still read-only.
The question is:
1. is there another, more efficient way to create JSF application from xsd files?
2. if this is the best way to do it, what do we do wrong?

Answer 1

To anyone who might find it useful: our solution to mentioned problem.
Few tips how to solve described problem:
1. Do not use JAXB (we checked Oracle and Sun)
2. Use castor http://www.castor.org/
a) for each xsd generate java files in separated package
b) use java 1.5 to let castor generate lists
c) use mapping of xml namespaces to java packages to have only 1 implementation of each xsd
3. Create facades - java files for you root-level java objects
4. Right click those facades and choose 'Create DataControl' in jdev
5. Now you may drag and drop you DataControls and use them in your JSF (or UIX) application
I hope it will help someone :)
