Rename generated XmlElements method to getContent

[baronnoraz]

It might be better to ask this on Stack Overflow, but I didn't see anything there or here.

I'm using the plugin to create Java Classes from a DTD. Everything is working. However, I have to conform to some "standards" that I can't seem to figure out how to do with the maven-jaxb2-plugin. I think it might be some change from JAXB 1 to 2 or something, but I can't figure out how to configure the plugin correctly to comply.

Given a DTD element like...

<!ELEMENT FOLDER (FOLDERVERSION| CONFIG| SCHEDULER)*>

The previous code would generate a Java class with a generic getContent method.

    @XmlElements({
        @XmlElement(name = "FOLDERVERSION", type = FOLDERVERSION.class),
        @XmlElement(name = "CONFIG", type = CONFIG.class),
        @XmlElement(name = "SCHEDULER", type = SCHEDULER.class)
    })
    protected List<Object> content;

    public List<Object> getContent() {
        if (content == null) {
            content = new ArrayList<Object>();
        }
        return this.content;
    }

However, using version 0.14.0 of the maven-jaxb2-plugin generates the following...

    @XmlElements({
        @XmlElement(name = "FOLDERVERSION", type = FOLDERVERSION.class),
        @XmlElement(name = "CONFIG", type = CONFIG.class),
        @XmlElement(name = "SCHEDULER", type = SCHEDULER.class)
    })
    protected List<Object> folderversionOrCONFIGOrSCHEDULER;

    public List<Object> getFOLDERVERSIONOrCONFIGOrSCHEDULER() {
        if (folderversionOrCONFIGOrSCHEDULER == null) {
            folderversionOrCONFIGOrSCHEDULER = new ArrayList<Object>();
        }
        return this.folderversionOrCONFIGOrSCHEDULER;
    }

How can I rename the generic choice method that's getting created?

You should really better ask this on StackOverflow.

This is not directly related to the maven-jaxb2-plugin so I'll close the issue. Backwards incompatibility might have been introduced by the newer version of XJC which maven-jaxb2-plugin now uses.

But here are a few hints.

I haven't touched DTD in ages, but DTD compilaton also support bindings to some extent. Google "xml-java-binding-schema", you will find a bit of documentation.

Unfortunately, seems like generated choice properties cannot be customized this way:

If I had this problem I would probably think of:

• converting DTD to XML Schema;
• if the only problem is the backwards compatibility, I'd add getContent method using code injector plugin;
• if I were me and had some spare time, I'd write an XJC plugin which could rename properties. This is not straightforward, but possible.

Thanks for the pointers and advice!
