Here is a test case using a file from SCORM for imsmanifest,xml. This XML has been in use for about 5 or more years, and being a standard I don't want to change it unless required to get this to work.
You can find the xsd file here
The error occurs between <organizations default="CYBER4.ORG"> and <organization identifier="CYBER4.ORG">
In my project, this is the entry from my pom.xml for my jaxb version
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.2.11</version>
</dependency>
to generate the Java code I ran (this is the install of xjc for Ubuntu 14.04)
$ xjc -version
xjc 2.2.4-2
$ xjc -verbose -p org.cyber4.scorm2004.xml.manifest.imscp imscp_v1p2.xsd
The output generates (amongst other things)
public class OrganizationsType {
@XmlAttribute(name = "default")
@XmlIDREF
@XmlSchemaType(name = "IDREF")
protected Object _default;
}
and
public class OrganizationType {
@XmlAttribute(name = "identifier", required = true)
@XmlJavaTypeAdapter(CollapsedStringAdapter.class)
@XmlID
@XmlSchemaType(name = "ID")
protected String identifier;
}
This is the test code

If I comment out line 37
organizationsType.setDefault("CYBER4.ORG");
it generates this XML
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<manifest xmlns="http://www.imsglobal.org/xsd/imscp_v1p1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.imsglobal.org/xsd/imscp_v1p1 imscp_v1p1.xsd">
<metadata/>
<organizations>
<organization identifier="CYBER4.ORG"/>
</organizations>
<resources/>
</manifest>
but it's missing the
default="CYBER4.ORG"
in <organizations> which is required for imsmanifest.xml to be valid.
This looks like this bug but I want to be sure I haven't missed anything.
default should not contain the id of the object you want to reference, but an object with the same id than the object you want to reference.
Try to replace :
organizationsType.setDefault("CYBER4.ORG");
with :
OrganizationType o = new OrganizationType()
o.setIdentifier("CYBER4.ORG");
organizationsType.setDefault(o);
If organizationType has already been set you can maybe also try :
organizationsType.setDefault(organizationType);
