recursive xsd generates java class with Objects instead of the given Type

So, I have an object which can contain a list of Objects of that type. I wrote an XSD which looks something like this:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="myNamespace" elementFormDefault="qualified">
<complexType name="BinModel">
<sequence>
<element type="string" name="min" />
<element type="string" name="max" />
<element type="string" name="fieldname" />
<element type="int" name="defaultValue" />
<element xmlns:ref="BinModel" name="innerBins" maxOccurs="unbounded" minOccurs="0" />
</sequence>
</complexType>
<element name="AllBins">
<complexType>
<sequence>
<element type="string" name="fieldnames" maxOccurs="unbounded" minOccurs="0"/>
<element type="int" name="defaultValue"/>
<element xmlns:type="BinModel" name="outerBins" maxOccurs="unbounded" minOccurs="0" />
</sequence>
</complexType>
</element>
</schema>
It produces two java classes, BinModel and AllBins respectively, but in each of those classes, even though I specify that they contain a list of type BinModel, it produces a List of type Object.
How do I generate a class which has a List of BinModels?

So I realized something was wrong when it took me adding xmlns before type and ref in order to not show errors in the editor. I looked at another xsd for a recursively defined Object somewhere else in my stupidly huge codebase to try and find a solution and discovered two things.
1. We were defining our own namespace
2. We referenced our own objects within that namespace.
So the corrected code looks something like this:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:myProject="projectNamespace" targetNamespace="myNamespace" elementFormDefault="qualified">
<complexType name="BinModel">
<sequence>
<element type="string" name="min" />
<element type="string" name="max" />
<element type="string" name="fieldname" />
<element type="int" name="defaultValue" />
<element type="myProject:BinModel" name="innerBins" maxOccurs="unbounded" minOccurs="0" />
</sequence>
</complexType>
<element name="AllBins">
<complexType>
<sequence>
<element type="string" name="fieldnames" maxOccurs="unbounded" minOccurs="0"/>
<element type="int" name="defaultValue"/>
<element type="myProject:BinModel" name="outerBins" maxOccurs="unbounded" minOccurs="0" />
</sequence>
</complexType>
</element>
</schema>

xml schema validation error “The content of element 'flowPara' is not complete”

I need to valid XSD for a XML file.
This is xml file.
<?xml version="1.0" encoding="UTF-8"?>

This is XSD file which i created .

</schema>
i faced this kind of exception
Exception: cvc-complex-type.2.4.b: The content of element 'flowPara' is not complete. One of '{"http://www.example.org/flow":flowspan}' is expected.

1) In your schema, you have flowspan with the s in lowercase in several places. Change that to flowSpan.
2) You declared mixed content, but your flowSpan element is not optional, so it will always be required and will not validate it if the contents of flowSpan don't contain another flowSpan. Add minOccurs="0" so it becomes optional.
3) You don't need to declare simple content if you have mixed content with an optional nested flowSpan. Your schema could be reorganized using a reference for flowSpan, since it's used recursively. You could try this:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.example.org/flow"
xmlns:tns="http://www.example.org/flow"
elementFormDefault="qualified">
<element name="edge">
<complexType>
<sequence>
<element name="flowPara" maxOccurs="unbounded">
<complexType mixed="true">
<sequence>
<element ref="tns:flowSpan" maxOccurs="unbounded"/>
</sequence>
<attribute name="style" type="string" />
<attribute name="id" type="string" />
</complexType>
</element>
</sequence>
</complexType>
</element>
<element name="flowSpan">
<complexType mixed="true">
<sequence>
<element ref="tns:flowSpan" minOccurs="0" maxOccurs="unbounded"/>
</sequence>
<attribute name="style" type="string" />
</complexType>
</element>
</schema>

You didn't say minOccurs='0', so it requires one.

Generated XSD does not unmarshall the XML

I have an XML string, and I could not use the supplied XSD to unmarshal the object in java. So I tried to use an online tool (www.freeformatter.com/xsd-generator.html) to generate a valid xsd and got the same error. I don't understand what I'm seeing.
Here's the XML:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Message xmlns:ns1="http://www.domain.com/ws" xmlns="http://www.domain.com/ws/protocol">
<HeaderMessage>
<MSGTYPE>reply</MSGTYPE>
<ORIGINATOR>XXXX</ORIGINATOR>
<SENDER>XXXX</SENDER>
<TIMESTAMP>2013-12-12 17:48:09.649</TIMESTAMP>
<IDPROCESS>2013-12-12 17:48:09.649</IDPROCESS>
<IDMESSAGE>AN-1386866889649</IDMESSAGE>
<IDREQUEST>AN-1386866889649</IDREQUEST>
<SERVICENAME>RESULT</SERVICENAME>
<ERRORFLAG>OK</ERRORFLAG>
<ERRORCODE>300</ERRORCODE>
<ERRORMSG>Success</ERRORMSG>
</HeaderMessage>
<BodyMessage>
<ns1:ServiceResultObject isin="XX0000000000">
<ns1:ResultObject value="true" codIsin="XX0000000000" />
</ns1:ServiceResultObject>
</BodyMessage>
</Message>
And here's the XSD I got from the tool:
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://www.domain.com/ws" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="ServiceResultObject">
<xs:complexType>
<xs:sequence>
<xs:element name="ResultObject">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attribute type="xs:string" name="value"/>
<xs:attribute type="xs:string" name="codIsin"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute type="xs:string" name="isin"/>
</xs:complexType>
</xs:element>
</xs:schema>
After I generate the classes, I get the error
javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.domain.com/ws/protocol", local:"Message"). Expected elements are <{http://www.domain.com/ws}ServiceResultObject>
Why do I lose all this header information? Why does the XSD not result in a schema that actually unmarshals the object? The XSD supplied by the service guys here also only defined the inner object.

Since your XML document has 2 namespaces (http://www.domain.com/ws/protocol & http://www.domain.com/ws) you are going to need 2 XML schemas to represent it. One schema can reference another with an import element.
XML Schemas
Below I have started the XML Schemas that you will need for your XML.
ws.xsd (for http://www.domain.com/ws namespace)
This is part of the XML schema for the http://www.domain.com/ws. The whole one is what you have already generated.
<?xml version="1.0" encoding="UTF-8"?>
<schema
xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.domain.com/ws"
xmlns:tns="http://www.domain.com/ws"
elementFormDefault="qualified">
<element name="ServiceResultObject">
<complexType>
<sequence/>
<attribute name="isin" type="string"/>
</complexType>
</element>
</schema>
ws_protocol.xsd (for http://www.domain.com/ws/protocol namespace)
Here is a partial version of the schema that you are missing for the http://www.domain.com/ws/protocol namespace. Note the import element that references the other XML Schema, and <element ref="ws:ServiceResultObject"/> which references an element from the other XML Schema.
<?xml version="1.0" encoding="UTF-8"?>
<schema
xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.domain.com/ws/protocol"
xmlns:tns="http://www.domain.com/ws/protocol"
xmlns:ws="http://www.domain.com/ws"
elementFormDefault="qualified">
<import namespace="http://www.domain.com/ws" schemaLocation="ws.xsd"/>
<element name="Message">
<complexType>
<sequence>
<element name="HeaderMessage">
<complexType>
<sequence>
<element name="MSGTYPE" type="string"/>
</sequence>
</complexType>
</element>
<element name="BodyMessage">
<complexType>
<sequence>
<element ref="ws:ServiceResultObject"/>
</sequence>
</complexType>
</element>
</sequence>
</complexType>
</element>
</schema>
Creating the JAXBContext
Once you have the two XML Schemas the classes will generate to 2 different packages. Below is an example of how to bootstrap the JAXBContext. Note that the package names are delimited by the : character.
JAXBContext jc = JAXBContext.newInstance("com.domain.ws:com.domain.ws.protocol");

Create a nested element with blank namespace in a schema definition

I have a remote system that returns an XML similar to the one below.
<BalanceResponse xmlns="http://example.com/balance">
<BalanceResult>
<Balance xmlns="">
<amount>10</amount>
<Balance>
</BalanceResult>
</BalanceResponse>
I created an xsd to match it
<s:schema elementFormDefault="qualified" targetNamespace="http://example.com/balance">
<s:element name="BalanceResponse">
<s:complexType>
<s:element minOccurs="0" maxOccurs="1" name="BalanceResult">
<s:complexType>
<s:element minOccurs="0" maxOccurs="1" name="Balance">
<s:complexType>
<s:element minOccurs="0" maxOccurs="1" name="amount" type="s:decimal" />
</s:complexType>
</s:element>
</s:complexType>
</s:element>
</s:complexType>
</s:schema>
I use JAXB to generate the stub classes. However, I know that my (un/)marshaller cannot bind the Balance element because the namespace is different.
Question is, how can i declare a different (blank)namespace for my element Balance?

You could do something like the following. Since elementFormDefault is unqualified all global elements (BalanceResponse and BalanceResult will be namespace qualified and all local elements (Balance and amount) won't be.
<?xml version="1.0" encoding="UTF-8"?>
<schema
xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://example.com/balance"
xmlns:tns="http://example.com/balance"
elementFormDefault="unqualified">
<element name="BalanceResponse">
<complexType>
<sequence>
<element ref="tns:BalanceResult"/>
</sequence>
</complexType>
</element>
<element name="BalanceResult">
<complexType>
<sequence>
<element name="Balance">
<complexType>
<sequence>
<element name="amount" type="int"/>
</sequence>
</complexType>
</element>
</sequence>
</complexType>
</element>
</schema>
If as in the XML Schema in your question put elementFormDefault as qualified then it would expect all of the XML elements to be namespace qualified.

Unmarshalling nested objects using JAXB

I am using JAXB and can't figure out why my nested objects aren't being unmarshalled. I am generating the classes via the XJC command.
For example, when I unmarshall the Works object, the Composers collection always contains one Composer instance will a NULL name.
My XML looks like this:
<Works>
<Work>
<Composer>
<Name>Test Name</Name>
</Composer>
</Work>
</Works>
and XSD is like this:
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
jxb:version="2.0" xmlns:tns="http://www.example.org/test/"
targetNamespace="http://www.example.org/test/">
<element name="Works" type="tns:Work"></element>
<complexType name="Work">
<sequence>
<element name="Composers" type="tns:Composer" maxOccurs="unbounded"
minOccurs="1">
</element>
</sequence>
</complexType>
<complexType name="Composer">
<sequence>
<element name="Name" type="string">
</element>
</sequence>
</complexType>
And my code that does the unmarshalling:
JAXBContext jc = JAXBContext.newInstance("mypackagename");
Unmarshaller um = jc.createUnmarshaller();
Works works = (Works)um.unmarshal(new FileReader("src/main/resources/works.xml"));
Work work = works.getWorks().get(0);
Composer composer = work.getComposers().get(0);
System.out.println(composer.getName());
Name is always NULL, even though I know it has a value.

You could have an XML schema like:
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
jxb:version="2.0" xmlns:tns="http://www.example.org/test/"
targetNamespace="http://www.example.org/test/">
<element name="Works" type="tns:Works"></element>
<complexType name="Works">
<sequence>
<element name="Work" type="tns:Work" maxOccurs="unbounded"/>
</sequence>
</complexType>
<complexType name="Work">
<sequence>
<element name="Composer" type="tns:Composer" maxOccurs="unbounded"/>
</sequence>
</complexType>
<complexType name="Composer">
<sequence>
<element name="Name" type="string"/>
</sequence>
</complexType>
</schema>
That corresponds to the following XML:
<Works xmlns="http://www.example.org/test/">
<Work>
<Composer>
<Name>Test Name</Name>
</Composer>
</Work>
</Works>
