I want to create a Java bean using the XML schema. I tried to create an XML schema from XML using freeformatter.com's XSD/XML Schema Generator. This is the XML schema that I have generated and is producing an error:
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://open-services.net/ns/core#" xmlns:xs="http://www.w3.org/2001/XMLSchema">

This is the error:
- src-resolve.4.2: Error resolving component 'rdf:parseType'. It was detected that 'rdf:parseType' is in namespace 'http://www.w3.org/1999/02/22-rdf-syntax-ns#', but
components from this namespace are not referenceable from schema document 'file:///home/workspace/jaxbexe/xsdfile.xsd'. If this is the incorrect namespace,
perhaps the prefix of 'rdf:parseType' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'file:///home/
workspace/jaxbexe/xsdfile.xsd'.
- s4s-elt-invalid-content.1: The content of '#AnonType_shortTitle' is invalid. Element 'attribute' is invalid, misplaced, or occurs too often.
Yes, this free tool seems to be unable to cope with namespaces. So either complain to the author to get it fixed, or use a different tool - there are plenty around.

I have to modify a project using XSD validation. I had got an XML, I transformed it to XSD via Intellij and then generated the associated code with the JAXB tool. All was fine.
But for the project needs, I had to modify the entire structure of my XML, I did it. I generate the XSD as well. But, When I tried to generate the Java code via the jaxb tools, it was impossible.
When I click in this jaxb tool, it just generated another XSD.
How can I do to generate, once again, the code ?
Thank you !
There is my XSD.

The problem that you are facing is a known issue, it is due to the fact that you have an attribute called value which is a protected name, such that you need to specify to xjc that it has to use a different name, it can be done by adding some meta information in your XSD file as next:
<xs:attribute type="xs:string" name="value" use="optional">
<xs:annotation>
<xs:appinfo>
<jaxb:property name="sqlQueryTypeValue"/>
</xs:appinfo>
</xs:annotation>
</xs:attribute>
You will also need to add the corresponding namespace declaration and the jaxb version to use, for example:
<xs:schema ... xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.1">

In my xsd, I have something like this:
<xs:complexType name="Disk">
<xs:attribute name="index" type="xs:int"></xs:attribute>
<xs:attribute name="providerId" type="xs:int"></xs:attribute>
<xs:attribute name="size" type="xs:int"></xs:attribute>
</xs:complexType>
<xs:complexType name="Server">
<xs:sequence>
<xs:element name="Disk" maxOccurs="unbounded" type="Disk"></xs:element>
</xs:sequence>
</xs:complexType>
I generated JAXB classes from above xsd and create an object of type Server and populated the arraylist named disk. Now when I try to marshal Server object to xml, I see:
<server><Disk index="0" providerId="123" size="10000"/><Disk index="1" providerId="1234" size="10000"/></server>
Is there any way by which I should see XML like:
<server><Disks><Disk index="0" providerId="123" size="10000"/><Disk index="1" providerId="1234" size="10000"/></Disks></server>
I want the list of disks xml tags to be enclosed in the tag. If it is possible, how to do it?
If u want tag can occurs many times in server tag use this.
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:complexType name="Disk">
<xs:attribute name="index" type="xs:int"></xs:attribute>
<xs:attribute name="providerId" type="xs:int"></xs:attribute>
<xs:attribute name="size" type="xs:int"></xs:attribute>
</xs:complexType>
<xs:complexType name="Server">
<xs:sequence>
<xs:element name="Disks" maxOccurs="unbounded" type="Disks"></xs:element>
</xs:sequence>
</xs:complexType>
<xs:complexType name="Disks">
<xs:sequence>
<xs:element name="Disk" maxOccurs="unbounded" type="Disk"></xs:element>
</xs:sequence>
</xs:complexType>
</xs:schema>
Or if you want Disks tag only once use following XSD
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:complexType name="Disk">
<xs:attribute name="index" type="xs:int"></xs:attribute>
<xs:attribute name="providerId" type="xs:int"></xs:attribute>
<xs:attribute name="size" type="xs:int"></xs:attribute>
</xs:complexType>
<xs:complexType name="Server">
<xs:sequence>
<xs:element name="Disks" minOccurs="0" maxOccurs="1" type="Disks"></xs:element>
</xs:sequence>
</xs:complexType>
<xs:complexType name="Disks">
<xs:sequence>
<xs:element name="Disk" maxOccurs="unbounded" type="Disk"></xs:element>
</xs:sequence>
</xs:complexType>
</xs:schema>
I am trying to generate JAXB model from the following xsd
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://abc.com/mmm/trt" attributeFormDefault="unqualified"
elementFormDefault="qualified">
<xs:annotation>
<xs:documentation>Schema for Cache Refresh Event.
</xs:documentation>
</xs:annotation>
<xs:simpleType name="cacheCode">
<xs:restriction base="xs:string">
<xs:enumeration value="BUSINESS_RULE" />
<xs:enumeration value="USER" />
</xs:restriction>
</xs:simpleType>
<xs:element name="cacheRefreshEvent">
<xs:complexType>
<xs:sequence>
<xs:element name="cacheCode" type="cacheCode" minOccurs="1"
maxOccurs="1" />
<xs:element name="entityRefId" type="xs:string" minOccurs="0"
maxOccurs="20" />
<xs:element name="cacheRefreshDate" type="xs:dateTime"
minOccurs="1" maxOccurs="1" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
But, it is giving me the following error, which i got in Eclipse console
parsing a schema...
[ERROR] src-resolve.4.1: Error resolving component 'cacheCode'. It was detected that 'cacheCode' has no namespace, but components with no target namespace are not referenceable from schema document 'file:/F:/Sprint6/cache/src/main/resources/CacheRefreshEvent.xsd'. If 'cacheCode' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'cacheCode' has no namespace, then an 'import' without a "namespace" attribute should be added to 'file:/F:/Sprint6/cache/src/main/resources/CacheRefreshEvent.xsd'.

Failed to parse a schema.
Please help.
Remove this extra namespace attribute targetNamespace="http://www.hcentive.com/mea/trr"
OR add this xmlns="http://www.hcentive.com/mea/trr"
Both solutions will work :)

In my schema file below, I have an element Stat which extends Entity. As far as I am aware, I follow w3's example, but when I go to parse the schema (and the xml that uses the schema) with through java's DocumentBuilderFactory and SchemaFactory I get this exception:
org.xml.sax.SAXParseException; systemId: file:/schema/characterschema.xsd;
src-resolve.4.2: Error resolving component 'cg:Entity'. It was detected that
'cg:Entity' is in namespace 'http://www.schemas.theliraeffect.com/chargen/entity',
but components from this namespace are not referenceable from schema document
'file:/home/andrew/QuasiWorkspace/CharacterGenerator/./schema/characterschema.xsd'.
If this is the incorrect namespace, perhaps the prefix of 'cg:Entity' needs
to be changed. If this is the correct namespace, then an appropriate 'import'
tag should be added to '/schema/characterschema.xsd'.
So, it seems that I cannot see my namespace within my schema. Do I need to import my schema into itself or am I completely misreading this exception? Could it be that I am declaring my schema incorrectly?
This is my schema for reference:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:cg="http://www.schemas.theliraeffect.com/chargen/entity"
elementFormDefault="qualified">
<xs:element name="Entity">
<xs:complexType>
<xs:attribute name="id" type="xs:string" use="required"/>
<xs:attribute name="name" type="xs:string"/>
<xs:attribute name="description" type="xs:string"/>
</xs:complexType>
</xs:element>
<xs:element name="Stat">
<xs:complexType>
<xs:complexContent>
<xs:extension base="cg:Entity">
<xs:sequence>
<xs:element name="table" type="xs:string" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:element>
</xs:schema>
There are two problems with your schema. First, you don't declare a targetNamespace so the Entity and Stat elements you are defining are not in a namespace. Second, a type can't extend an element, only another type.
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:cg="http://www.schemas.theliraeffect.com/chargen/entity"
targetNamespace="http://www.schemas.theliraeffect.com/chargen/entity"
elementFormDefault="qualified">
<xs:complexType name="EntityType">
<xs:attribute name="id" type="xs:string" use="required"/>
<xs:attribute name="name" type="xs:string"/>
<xs:attribute name="description" type="xs:string"/>
</xs:complexType>
<xs:element name="Entity" type="cg:EntityType" />
<xs:complexType name="StatType">
<xs:complexContent>
<xs:extension base="cg:EntityType">
<xs:sequence>
<xs:element name="table" type="xs:string" minOccurs="0"
maxOccurs="unbounded"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:element name="Stat" type="cg:StatType" />
</xs:schema>
Here I'm defining two types, one of which extends the other, and two top level elements of the respective types. All the top-level types and elements are defined into the targetNamespace of the schema, and the nested table element inside StatType is also in this namespace because of the elementFormDefault="qualified" - without this the Entity and Stat elements would be in the http://www.schemas.theliraeffect.com/chargen/entity namespace but the table element would be in no namespace.
I'm using the JAXB xjc tool to generate some Java interface files from xsds. I'm running into a problem where I'm getting a tonne of errors of the form:
org.xml.sax.SAXParseException: ct-props-correct.4: Error for type 'COCT_MT110200CA.PayeeRole'. Duplicate attribute uses with the same name and target namespace are specified. Name of duplicate attribute use is 'nullFlavor'.
The relevant parts of the schema are as follows:
<xs:complexType name="COCT_MT110200CA.Holder">
<xs:sequence>
<xs:group ref="InfrastructureRootElements"/>
<xs:element name="payeeRole" type="COCT_MT110200CA.PayeeRole" minOccurs="1" maxOccurs="1">
</xs:element>
</xs:sequence>
<xs:attributeGroup ref="InfrastructureRootAttributes"/>
<xs:attribute name="nullFlavor" type="NullFlavor" use="optional"/>
<xs:attribute name="typeCode" type="ParticipationType" use="optional" fixed="HLD"/>
</xs:complexType>
Where COCT_MT110200CA.PayeeRole is defined as:
<xs:complexType name="COCT_MT110200CA.PayeeRole">
<xs:sequence>
<xs:group ref="InfrastructureRootElements"/>
<xs:element name="id" type="II" minOccurs="0" maxOccurs="unbounded">
</xs:element>
<xs:choice>
<xs:element name="payeePerson" type="COCT_MT110200CA.PayeePerson" nillable="true"
minOccurs="0"
maxOccurs="1">
</xs:element>
<xs:element name="payeeOrganization" type="COCT_MT110200CA.PayeeOrganization"
nillable="true"
minOccurs="0"
maxOccurs="1">
</xs:element>
</xs:choice>
</xs:sequence>
<xs:attributeGroup ref="InfrastructureRootAttributes"/>
<xs:attribute name="nullFlavor" type="NullFlavor" use="optional"/>
<xs:attribute name="classCode" type="RoleClass" use="optional" fixed="PAYEE"/>
</xs:complexType>
Any thoughts? I don't see anything wrong with this myself...
Oooh, I think I figured this out, there was a pesky attributeGroup (InfrastructureRootAttributes) there, and in that attributeGroup was the nullFlavor duplicate...
