如何在命令行中使用带有XJC的jaxb2-annotate-plugin

Question

I'm building java classes based on an xsd using "jaxb-ri" in command line (xjc.bat). I want to set a namespace in an XmlType annotation using jaxb2-annotate_plugin but I don't know how to add this plugin to xjc classpath and acitvate it.

here is my external bindings.xjb file :

<jxb:bindings xmlns:jxb="http://java.sun.com/xml/ns/jaxb" 
              xmlns:xs="http://www.w3.org/2001/XMLSchema"
              xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
              xmlns:annox="http://annox.dev.java.net"
              jxb:extensionBindingPrefixes="xjc annox"
              version="2.1">
    <jxb:bindings schemaLocation="myschema.xsd" node="/xs:schema">
        <jxb:bindings node="xs:complexType[@name='MyType]">
            <annox:annotateClass>@javax.xml.bind.annotation.XmlType(namespace="urn:myschematwo")</annox:annotateClass>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

My command line is :

D:/jaxb-ri/bin/xjc.bat -p "com.jaxb.mypackage" -d
"D:/myproject/src/main/java" D:/myschema.xsd -b "D:/bindings.xjb"
-extension

When I execute this command, I have an error message saying that " http://annox.dev.java.net " is not supported.

Thanks in advance.

Disclaimer: I'm the author of jaxb2-annotate-plugin .

First, I don't provide sample for command line as (as far as I know) nobody uses command line or batch scripts for schema compilation. At least up to date there were no requests for that. There are samples for Ant and Maven , the one for Ant is the closes to the command line usage.

Next, I wonder what is in xjc.bat .

If it calls xjc.exe from Java distibution, this most probably won't work with third-party plugins at all, not just with the jaxb2-annotate-plugin . The reason is that the XJC version which is distributed with Java has a renamed package: com.sun.tools.** -> com.sun.tools.internal.** . This breaks, naturally compagtibility with plugins. So please make sure xjc.bat does not call the xjc.exe contained in the Java distro.

I hope xjc.bat calls com.sun.tools.xjc.XJCFacade from JAXB RI Jars.

To execute the plugin you'll need two things:

• Include all the required dependencies to the classpath.
• Turn the plugin on using -Xannotate command line parameter.

These dependencies are:

                <!-- JAXB2 Basics library -->
                <include name="jaxb2-basics-*.jar"/>
                <include name="jaxb2-basics-annotate*.jar"/>
                <!-- JAXB2 Basics library dependencies -->
                <include name="annox-*.jar"/>
                <include name="javaparser-*.jar"/>
                <include name="commons-beanutils-*.jar"/>
                <include name="commons-logging-*.jar"/>
                <include name="commons-lang3-*.jar"/>

Maven stuff is unrelated, otherwise you should be able to see the versions.

Hope this helps.

To be honest, I am a bit reluctant to invest time in batch/command-line sample. But if you'll get one working, I'd add it to samples.

Why do you actually need it in the command line?
