JAX-WS: Compile Schema separate from WSDL

Question

If have a rather large schema that is used in several webservices, therefore I want to separate XSD compilation from WSDL compilation. In a simplified example, compiling in a single step works:

$ wsimport -verbose service.wsdl parsing WSDL...  Generating code...  org/example/wsdl/mysvc/MySvcPortType.java org/example/wsdl/mysvc/MySvcService.java org/example/ns1/Element1.java org/example/ns1/ObjectFactory.java org/example/ns1/package-info.java ... 

Compiling the xsd and using the resulting episode file does not work:

$ wsimport -b schema3.episode service.wsdl   parsing WSDL...  [ERROR] Schema descriptor {http://www.example.org/ns1}element1 in message part "part1" is not defined and could not be bound to Java. Perhaps the schema descriptor {http://www.example.org/ns1}element1 is not defined in the schema imported/included in the WSDL. You can either add such imports/includes or run wsimport and provide the schema location using -b switch.   line 9 of file:...jaxepisode_element/service.wsdl 

So how can I use the precompiled schema in wsimport?

Addendum: Using the episode when including in another schema works and avoids new compilation (d3.jar contains the genrated classes from schema3 + schema3.episode as META-INF/sun-jaxb.episode):

$ xjc schema4.xsd d3.jar -extension parsing a schema...  compiling a schema...  org/example/ns2/Element2.java org/example/ns2/ObjectFactory.java org/example/ns2/package-info.java 

Without the precompiled package:

$ xjc schema4.xsd  -extension parsing a schema... compiling a schema... org/example/ns1/Element1.java org/example/ns1/ObjectFactory.java org/example/ns1/package-info.java org/example/ns2/Element2.java org/example/ns2/ObjectFactory.java org/example/ns2/package-info.java 

WSDL:

<definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://example.org/wsdl/MySvc" xmlns:ns="http://www.example.org/ns1" targetNamespace="http://example.org/wsdl/MySvc" name="MySvc">   <types>     <xsd:schema>       <xsd:import namespace="http://www.example.org/ns1" schemaLocation="schema3.xsd"/>     </xsd:schema>   </types>   <message name="myOpRequest">     <part name="part1" element="ns:element1"/>   </message>   <message name="myOpReply">     <part name="part1" element="ns:element1"/>   </message>   <portType name="MySvcPortType">     <operation name="myOp">       <input name="input1" message="tns:myOpRequest"/>       <output name="output1" message="tns:myOpReply"/>     </operation>   </portType>   <binding name="MySvcBinding" type="tns:MySvcPortType">     <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>     <operation name="myOp">       <soap:operation/>       <input name="input1">         <soap:body use="literal"/>       </input>       <output name="output1">         <soap:body use="literal"/>       </output>     </operation>   </binding>   <service name="MySvcService">     <port name="MySvcPort" binding="tns:MySvcBinding">       <soap:address location="http://localhost:8080/"/>     </port>   </service> </definitions> 

schema3.xsd:

<schema      xmlns="http://www.w3.org/2001/XMLSchema"      targetNamespace="http://www.example.org/ns1"      xmlns:tns="http://www.example.org/ns1"      elementFormDefault="qualified">   <element name="element1" >     <complexType >         <sequence>                 <element name="name" type="string" />         </sequence>      </complexType>    </element> </schema> 

schema4.xsd:

<schema      xmlns="http://www.w3.org/2001/XMLSchema"      targetNamespace="http://www.example.org/ns2"      xmlns:tns="http://www.example.org/ns2"      xmlns:ns1="http://www.example.org/ns1"      elementFormDefault="qualified">      <import namespace="http://www.example.org/ns1" schemaLocation="schema3.xsd"/>      <element name="element2" >       <complexType >         <sequence>           <element ref="ns1:element1" />         </sequence>        </complexType>      </element> </schema> 

The generated episode file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <bindings version="2.1" xmlns="http://java.sun.com/xml/ns/jaxb">   <bindings scd="x-schema::tns" xmlns:tns="http://www.example.org/ns1">     <schemaBindings map="false">       <package name="org.example.ns1"/>     </schemaBindings>     <bindings scd="tns:element1">       <class ref="org.example.ns1.Element1"/>     </bindings>   </bindings> </bindings>

You can use maven, separate for each and Generate with Apache CXF.

• http://cxf.apache.org/

I have an example that can help you.

properties:

 <properties>     <apache.cxf.version>3.0.4</apache.cxf.version>     <cxf-codegen-plugin.version>3.0.4</cxf-codegen-plugin.version>     <cxf-xjc-plugin.version>3.0.3</cxf-xjc-plugin.version>  </properties> 

dependencies:

You can create a maven project to generate only the wsdl and another to only generate the xsd.

NOTE:

If his project does not require use the WSDL, switch to the json-rest-api.

Use REST and be happy. \o/

I hope this helps.
