JAXB External Custom Binding XJC Issue - Parsing results in empty node - jaxb

Question

Forgive me if this is a duplicate. Here is my binding.xjb file. But now i am getting the regular error that the complex type target "AddBankVaultRplyType" is not found. I don't see any issue. Can somebody help me with this? I am listing the xsd that i am trying to customize
<jxb:bindings
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
xmlns:pd="http://chubb.com/cpi/polsvc/xmlobj"
xmlns:inheritance="http://jaxb2-commons.dev.java.net/basic/inheritance"
jxb:extensionBindingPrefixes="inheritance"
jxb:version="2.1"
>
<jxb:bindings node="/xs:schema/xs:ServiceReply/xs:complexType[#name='AddBankVaultRplyType']">
<inheritance:extends>com.print.poc.AddressTypeHelper</inheritance:extends>
</jxb:bindings>
Here is the piece of XSD that i am trying to customize
<xs:schema xmlns:pd="http://com/polsvc/xmlobj" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://com/polsvc/xmlobj" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:complexType name="AddBankVaultRplyType">
</xs:complexType>
<xs:element name="ServiceReply">
<xs:complexType>
<xs:sequence>
<xs:element name="ReplyHeader" type="pd:MsgHeaderType"/>
<xs:element name="RequestHeader" type="pd:MsgHeaderType"/>
<xs:choice>
<xs:element name="AddBankVaultReply" type="pd:AddBankVaultRplyType"/>
</xs:choice>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Now if i run XJC it is saying me that the target "/xs:schema/xs:ServiceReply/xs:complexType[#name='AddBankVaultRplyType']" results in empty node. What is the mistake i am doing here

Answer 1

You will need to wrap in a bindings that has the schema location set. It should be something like:
<jxb:bindings
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
xmlns:pd="http://chubb.com/cpi/polsvc/xmlobj"
xmlns:inheritance="http://jaxb2-commons.dev.java.net/basic/inheritance"
jxb:extensionBindingPrefixes="inheritance"
version="2.1">
<jxb:bindings schemaLocation="your-schema.xsd">
<jxb:bindings node="//xs:complexType[#name='AddBankVaultRplyType']">
<inheritance:extends>com.print.poc.AddressTypeHelper</inheritance:extends>
</jxb:bindings>
</jxb:bindings>
</jxb:bindings>

I finally got mine workign with subclassing as well as adding #XmlRootElement to those dang complexTypes that are used by a root element(I don't get why JAXB doesn't add it for me, but this does the trick of doing that since JAXB doesn't)
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<jaxb:bindings
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:annox="http://annox.dev.java.net"
xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd
http://annox.dev.java.net "
jaxb:extensionBindingPrefixes="xjc annox"
version="2.1">
<jaxb:globalBindings>
<jaxb:serializable uid="1"/>
<!-- All generated classes must have MySignature interface (supplied in dependencies) -->
<xjc:superClass name="com.cigna.framework.DataObject"/>
<xjc:superInterface name="com.cigna.framework.InterfaceTest"/>
<!-- All temporal fields are implemented as Joda DateTime and use DateUtils as an adapter -->
<jaxb:javaType

printMethod="com.cigna.framework.util.DateUtil.dateTimeToString"
/>
</jaxb:globalBindings>
<!-- Application of annotations to selected classes within schemas -->
<!-- org.example.SomeRootType #XmlRootElement -->
<jaxb:bindings schemaLocation="../schemas/externalaction_2012_03.xsd" node="/xs:schema">
<jaxb:schemaBindings >
<jaxb:package name="com.framework.action"></jaxb:package>
</jaxb:schemaBindings>
</jaxb:bindings>
<jaxb:bindings schemaLocation="../schemas/common_2012_04.xsd" node="/xs:schema">
<jaxb:schemaBindings >
<jaxb:package name="com.framework.common"></jaxb:package>
</jaxb:schemaBindings>
<jaxb:bindings node="xs:complexType[#name='PersonNameType']">
<annox:annotate>
<annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="SomeRootType"/>
</annox:annotate>
</jaxb:bindings>
</jaxb:bindings>
<jaxb:bindings schemaLocation="../schemas/utilities_2012_03.xsd" node="/xs:schema">
<jaxb:schemaBindings >
<jaxb:package name="com.framework.util"></jaxb:package>
</jaxb:schemaBindings>
</jaxb:bindings>
</jaxb:bindings>
Of course I struggled with the pom.xml alot but finally came to this solution which worked for me.
