This blog is very much helpful for me for maven implementation project from converting ant to maven script.
This plugin works great but only problem i am facing right now is
java source file generating from xsd is like this

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = “AccountBaseType”, propOrder = {
“accountId”,
“accountSummary”

but I want to generate like this

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = “AccountBaseType”, namespace = “http://services.com/11/basetypes/account”, propOrder = {
“accountId”,
“accountSummary”
})

Thanks,
Darshan

Nice post you put. I liked it and want to use in my application.
But when i followed your steps and try to build the project got the below error.

Could you please help me out?

I have limited experience with JAXB, I have an issue which is boggling me for over some time.

I have a XSD which looks something like this(Forgive my xsd typos, In essence CustomerList can have many customers…) :

#######################################################################################################################################################################

########################################################################################################################################################################

I use the jaxb2-maven-plugin – xjc goal – to generate the sources

The generated Class CustomerList.java has @XmlRootElement annotation to it, but the generated class Customer.java has no @XmlRootElement annotation to it.

Now, get the Customer data in XML in the following sample format :
****************************************************************

Tester
a
Interface
.
.
.

******************************************************************

I cannot unmarshall that by providing Customer.java as input to the following code….


Customer cust =(Customer) EncodeUtils.DecodeString(xmlRequest, Customer.class);

JAXBContext context = JAXBContext.newInstance(objectClass);
StringReader strReader = new StringReader(input);
Unmarshaller un = context.createUnmarshaller();
return un.unmarshal(strReader);
}


it would throw up a javax.xml.bind.UnmarshalException: unexpected element (uri:””, local:…. … … error.

So in essence my req has come down to be able to unmarshal the string the Customer XML to string to Customer.java which doean’t contain @XMLRootElement annotation. If I add that manually the problem is solved, but my use case won’t allow me to do that. Somehow I should be able think of a way programmatically to do that.

What would be my options to solve the issue(I cannot change the XSD, If I have to I must have a strong argument towards that).

Any help or input would be greatly appreciated, Although I googled for this, I couldn’t make mush sense of options there.

Thank you very much. Sorry for the long post.

Anyway, I think the XML might be invalid. Can you use an XML validation tool (like Eclipse, XMLSpy) or an online tool and confirm if the XML is valid when validated against the schema.
