@xmlschema jaxb package-info.java compilation error

问题

I'm trying to use annotations at package level but I get compilation erros from Eclipse.

I have a class Head with the following package/annotation:

 @javax.xml.bind.annotation.XmlSchema (
    xmlns = { 
      @javax.xml.bind.annotation.XmlNs(prefix = "com", 
                 namespaceURI="http://es.indra.transporte.common"),
      @javax.xml.bind.annotation.XmlNs( namespaceURI="http://www.w3.org/2001/XMLSchema")          
    },
    namespace = "http://es.indra.transporte.common", 
    elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED,
    attributeFormDefault = javax.xml.bind.annotation.XmlNsForm.UNQUALIFIED
  )  
package es.indra.transporte.central.thalesinterface.common.beans;

I have created a package-info.java in es.indra.transporte.central.thalesinterface.common.beans folder with the above code but I'm still getting the compilation error

Package annotations must be in file package-info.java

in Head class. I'm using jdk6.

The only problem I got when trying to compile your package info was that the @XmlNs annotation was missing the prefix property.

This:

@javax.xml.bind.annotation.XmlNs( namespaceURI="http://www.w3.org/2001/XMLSchema")

Should be:

@javax.xml.bind.annotation.XmlNs(prefix="xsd",  namespaceURI="http://www.w3.org/2001/XMLSchema")

The following corrected code should compile:

@javax.xml.bind.annotation.XmlSchema (
    xmlns = { 
      @javax.xml.bind.annotation.XmlNs(prefix = "com", 
                 namespaceURI="http://es.indra.transporte.common"),
      @javax.xml.bind.annotation.XmlNs(prefix="xsd", namespaceURI="http://www.w3.org/2001/XMLSchema")
    },
    namespace = "http://es.indra.transporte.common", 
    elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED,
    attributeFormDefault = javax.xml.bind.annotation.XmlNsForm.UNQUALIFIED
  )  
package es.indra.transporte.central.thalesinterface.common.beans;
