I have multiple XSD files, and I want to run an XJC over them to create java class objects, which I use for further processing. ISSUE: 2 XSDs among my set of XSDs have an issue when I run the XJC command. The XSDs are:

contactLM.xsd 

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
            xmlns:w="http://w.com/xsd" 
            xmlns="http://w.com/location.contactlm" 
            xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
            targetNamespace="http://w.com/location.contactlm" 
            elementFormDefault="qualified" jaxb:version="2.1">
  <xsd:annotation>
    <xsd:appinfo>
      <jaxb:schemaBindings>
        <jaxb:package name="location.contactlm"/> 
      </jaxb:schemaBindings>
    </xsd:appinfo>
  </xsd:annotation>

  <xsd:element name="Contact" type="Contact" nillable="true"/>

  <xsd:complexType name="Contact">
    <xsd:sequence>
      <xsd:element name="RefID" type="xsd:string" nillable="true" 
                   minOccurs="0" gw:type="java.lang.String"/>
    </xsd:sequence>
  </xsd:complexType>


</xsd:schema>

contactM.xsd

<?xml version="1.0"?>
<xsd:schema
      xmlns:xsd="http://www.w3.org/2001/XMLSchema"
      xmlns:w="http://w.com/xsd"
      xmlns="http://w.com/location.contactm"
      targetNamespace="http://w.com/location.contactm"
      elementFormDefault="qualified"
      xmlns:ns0="http://w.com/location.contactam"
      xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"  
      jaxb:version="2.1">
  <xsd:annotation>
    <xsd:appinfo>
      <jaxb:schemaBindings>
        <jaxb:package name="location.contactm"/>
      </jaxb:schemaBindings>
    </xsd:appinfo>
  </xsd:annotation>
  <xsd:import namespace="http://w.com/location.contactam"
              schemaLocation="ContactAM.xsd"/>
  <xsd:element name="Contact" type="Contact" nillable="true"/>
  <xsd:complexType name="Contact">
    <xsd:sequence>
      <xsd:element name="RefID" minOccurs="0" nillable="true" 
                   type="xsd:string" gw:type="java.lang.String"/>
      <xsd:element name="WorkPhone" minOccurs="0" nillable="true" 
                   type="xsd:string" gw:type="java.lang.String"/>
    </xsd:sequence>
  </xsd:complexType>
</xsd:schema>

I know there is a reference to the same "contact" in these XSD files, and THAT is an issue. SO, I had to write my XJB file. I have the following xjb file written:

<jaxb:bindings
  xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
  xmlns:gw="http://w.com/xsd" 
  xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  elementFormDefault="qualified" 
  xmlns="http://w.com/location.contactlm" 

  targetNamespace="http://w.com/location.contactlm" 
  jaxb:version="2.1">

     <jaxb:bindings schemaLocation="ContactM.xsd">
        <jaxb:bindings node=".//xs:element[@name='Contact']">
            <jaxb:class name="ContactM"/>
        </jaxb:bindings>
        <jaxb:schemaBindings>
            <jaxb:package name="location.contactm" />
        </jaxb:schemaBindings>
    </jaxb:bindings>

   <jaxb:bindings schemaLocation="ContactLM.xsd">
        <jaxb:bindings node=".//xs:element[@name='Contact']">
            <jaxb:class name="ContactCLM"/>
        </jaxb:bindings>
        <jaxb:schemaBindings>
            <jaxb:package name="location.contactlm" />
        </jaxb:schemaBindings>
    </jaxb:bindings>

</jaxb:bindings>

but i get the following error when I do:

xjc -d src -b C:\us\binding.xjb C:\us\trunk\shared\

I guess I might be doing something wrong in the XJB file, but I'm unable to fix the issue. Someone please help.

Soluzione

What you mainly need to do is remove the scheme binding from your xsd files. I've copied and tested your files and it worked. However, I changed the reference to ContactAM to ContactLMassuming it was a typo.

Here are my files:

ContactM.xsd

<?xml version="1.0"?>
<xsd:schema
      xmlns:xsd="http://www.w3.org/2001/XMLSchema"
      xmlns:gw="http://w.com/xsd"
      xmlns="http://w.com/location.contactm"
      targetNamespace="http://w.com/location.contactm"
      elementFormDefault="qualified"
      xmlns:ns0="http://w.com/location.contactam"
      xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"  
      jaxb:version="2.1">
  <xsd:annotation>
    <xsd:appinfo>
<!--       <jaxb:schemaBindings> -->
<!--         <jaxb:package name="location.contactm"/> -->
<!--       </jaxb:schemaBindings> -->
    </xsd:appinfo>
  </xsd:annotation>
  <xsd:import namespace="http://w.com/location.contactlm"
              schemaLocation="ContactLM.xsd"/>
  <xsd:element name="Contact" type="Contact" nillable="true"/>
  <xsd:complexType name="Contact">
    <xsd:sequence>
      <xsd:element name="RefID" minOccurs="0" nillable="true" 
                   type="xsd:string" gw:type="java.lang.String"/>
      <xsd:element name="WorkPhone" minOccurs="0" nillable="true" 
                   type="xsd:string" gw:type="java.lang.String"/>
    </xsd:sequence>
  </xsd:complexType>
</xsd:schema>

ContactLM.xsd

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
            xmlns:gw="http://w.com/xsd" 
            xmlns="http://w.com/location.contactlm" 
            xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
            targetNamespace="http://w.com/location.contactlm" 
            elementFormDefault="qualified" jaxb:version="2.1">
  <xsd:annotation>
    <xsd:appinfo>
<!--       <jaxb:schemaBindings> -->
<!--         <jaxb:package name="location.contactm"/> -->
<!--       </jaxb:schemaBindings> -->
    </xsd:appinfo>
  </xsd:annotation>

  <xsd:element name="Contact" type="Contact" nillable="true"/>

  <xsd:complexType name="Contact">
    <xsd:sequence>
      <xsd:element name="RefID" type="xsd:string" nillable="true" 
                   minOccurs="0" gw:type="java.lang.String"/>
    </xsd:sequence>
  </xsd:complexType>


</xsd:schema>

and finally the binding file:

bind.xjb

<jaxb:bindings
  xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
  xmlns:gw="http://w.com/xsd" 
  xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  elementFormDefault="qualified" 
  xmlns="http://w.com/location.contactlm" 

  targetNamespace="http://w.com/location.contactlm" 
  jaxb:version="2.1">

     <jaxb:bindings schemaLocation="ContactM.xsd">
        <jaxb:bindings node=".//xs:element[@name='Contact']">
            <jaxb:class name="ContactM"/>
        </jaxb:bindings>
        <jaxb:schemaBindings>
            <jaxb:package name="location.contactm" />
        </jaxb:schemaBindings>
    </jaxb:bindings>

   <jaxb:bindings schemaLocation="ContactLM.xsd">
        <jaxb:bindings node=".//xs:element[@name='Contact']">
            <jaxb:class name="ContactCLM"/>
        </jaxb:bindings>
        <jaxb:schemaBindings>
            <jaxb:package name="location.contactlm" />
        </jaxb:schemaBindings>
    </jaxb:bindings>

</jaxb:bindings>

And for completeness, here's my command and its output

D:\stackoverflow\sample>xjc ContactM.xsd -b bind.xjb
parsing a schema...
compiling a schema...
location\contactm\Contact.java
location\contactm\ContactM.java

location\contactm\package-info.java
location\contactlm\Contact.java
location\contactlm\ContactCLM.java
location\contactlm\ObjectFactory.java
location\contactlm\package-info.java

Hope this helps.
