XML namespace inheritance

Let's say I have following xsd schema:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:element name="kom">
<xs:complexType>
<xs:sequence>
<xs:element name="um">
<xs:complexType>
<xs:attribute name="odd"
type="TypKod"
use="required"/>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="version" use="required">
<xs:simpleType>
<xs:restriction base="xs:normalizedString">
<xs:length value="3"/>
<xs:enumeration value="1.0"/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>
<xs:attribute name="od" type="TypKod" use="required"/>
</xs:complexType>
</xs:element>
<xs:simpleType name="TypKod">
<xs:restriction base="xs:normalizedString">
<xs:length value="2" fixed="true"/>
<xs:enumeration value="01"/>
</xs:restriction>
</xs:simpleType>
And I have following soap UI envelope:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:b="http://xml.daniel.pl/b"
xmlns:c="http://xml.daniel.pl/c"
xmlns:xm="http://www.w3.org/2005/05/xmlmime">
<soapenv:Header/>
<soapenv:Body>
<b:execute>
<b:date>2013-12-06T12:32:41.106+01:00</:date>
<b:pay>
<b:text>
<p:kom xmlns:p="http://daniel/p" version="1.0" od="01">
<um odd="01"/>
</p:kom>
</b:text>
</b:payload>
</b:execute>
</soapenv:Body>
</soapenv:Envelope>
The question is, shouldn't it be
<p:um odd="01"/>
instead of
<um odd="01"/>
?
Element um belongs to namespace 'p' but i don't know how to prepare schema.
In code generated by axis I have:
if (reader.isStartElement() && new javax.xml.namespace.QName("","um").equals(reader.getName()))
so there is empty string before 'um'. How can I make it to put there my namespace 'p' without manual modification of classes generated by axis?
When I put <p:um odd="01"/> in the envelope I get:
Caused by: java.lang.Exception: org.apache.axis2.databinding.ADBException: Unexpected subelement {http://daniel/p}um

xml schema and java objects

I have received xml schema from a third party vendor. However the xml schema and the xml don't seem to match atleast that is my guess. I am using Intellij and use the JAXB plugin to get JAVA objects.
My code never returns the field values i.e. it never returns "my string value" back from xml
<field type="Address">
<value type="Value">my string value</value>
</field>
I get data back as
0 = {FieldType#1372}
characters = null
value = {FieldTypeType#1381} "ADDRESS"
value = {String#1383} "Address"
data = null
name = {String#1382} "ADDRESS"
ordinal = 8
1 = {FieldType#1373}
characters = null
value = {FieldTypeType#1387} "CARD_NUMBER"
2 = {FieldType#1374}
characters = null
value = {FieldTypeType#1389} "DATE"
3 = {FieldType#1375}
I have the xml as this (part of it)
<field type="Address">
<value type="Value">my string value</value>
</field>
<field type="CardNumber">
<value type="Value">xxxxx</value>
</field>
<field type="Date">
<value type="Day">21</value>
<value type="Month">4</value>
<value type="Year">2015</value>
</field>
<field type="Phone">
<value type="Value">212XXX</value>
</field>
<field type="SubTotal">
<value type="value">XXX</value>
</field>
and schema is
<xs:complexType name="receiptType">
<xs:sequence>
<xs:element name="field" type="tns:fieldType" minOccurs="0" maxOccurs="unbounded"></xs:element>

Appreciate all the help!

My XSD does not validate the XML despite proper namespace declarations

The XSD <schema> tag:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.cmu.edu/ns/blank"
targetNamespace="http://www.cmu.edu/ns/blank"

xsi:schemaLocation="http://www.cmu.edu/ns/blank student.xsd">
How ever I get en error that:
cvc-elt.1.a: Cannot find the declaration of element 'people'
I know it has something to do with namespaces but I can not figure out what.
Please help

The only thing that's not working is the schema location attribute's namespace. The XML Schema Instance namespace is:
http://www.w3.org/2001/XMLSchema-instance
instead of:
http://www.w3c.org/2001/XMLSchema-instance (you put a c in w3c)
For the given XML, the error is
The 'http://www.w3c.org/2001/XMLSchema-instance:schemaLocation' attribute is not declared.

Error while generating JAXB model from xsd in eclipse

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'.
line 18 of 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 :)
For you reference targetnamespace-and-xmlns

XML validation against XSD: cvc-elt.1: Cannot find the declaration of element 'xxx'

I have the following XML file:
<?xml version="1.0"?>
<!DOCTYPE library SYSTEM "library.dtd">
<library
xmlns="http://example.com/a"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://example.com library.xsd"
name=".NET Developer's Library">
<book>
<category>computerss</category>
<title>Programming Microsoft .NET</title>
<author>Jeff Prosise</author>
<isbn>0-7356-1376-1</isbn>
</book>
<book>
<category>computer</category>
<title>Microsoft .NET for Programmers</title>
<author>Fergal Grimes</author>
<isbn>1-930110-19-7</isbn>
</book>
</library>
And the following Java code:
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
SchemaFactory sf = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");
docBuilderFactory.setSchema(sf.newSchema(new File("library.xsd")));
docBuilderFactory.setNamespaceAware(true);
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
docBuilder.parse(new FileInputStream("data.xml"));
It produces the following error:
[Error] :7:33: cvc-elt.1: Cannot find the declaration of element 'library'.
If I remove the XSD declaration in the XML file everything works fine...
Any inside highly appreciated. Thanks.
And here is the schema:
<?xml version="1.0" encoding="UTF-8"?>

Your XML has a reference to namespace (xmlns="http://example.com/a") which is not the same as in your schema. Have you tried to validate your XML against schema in any XML editor (e.g. Altova or Eclipse etc).
So far it looks like your parsing error is legit, XML is not valid according to the schema.

Your schema definition is incorrect. For a start, as maximdim says, your schema has no targetNamespace="http://mysite.com/a" attribute in the schema tag.
Secondly your schema looks as if it should only have a single root element, yours has 6.
A correct schema for your XML instance would be:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://mysite.com/a" targetNamespace="http://mysite.com/a">
<xs:element name="library">
<xs:complexType>
<xs:sequence>
<xs:element name="book" type="book" maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:complexType name="book">
<xs:sequence>
<xs:element name="category">

<xs:restriction base="xs:string">
<xs:enumeration value="computer" />
<xs:enumeration value="poetry" />
