I have written a custom mapping to go from Oracle 11g's proprietary xmltype data type to org.w3c.dom.Document and back again. I have applied this mapping in my POJO as follows:
Code:
@Column(name = "DOC_XML", nullable = false)
@org.hibernate.annotations.Type(type = "persistence.oracle.xml.OracleXmlMapping")
public Document getText() {
return text;
}
public void setText(Document text) {
this.text = text;
}
In my IDE IntelliJ I get a red squiggly line under Document (the return type of the getter) saying "'unknown' attribute type is invalid." More generally though, when I compile and then run Hibernate Tools in Maven, I get the following exception:
Code:

Incidentally, in my OracleXMLMapping custom mapping class, I have the following:
Code:
private static final int[] SQL_TYPES = new int[]{oracle.xdb.XMLType._SQL_TYPECODE};
If I just try to run tests by bypassing Hibernate Tools, I get this:
Code:

I checked and found that the class is found in my classpath in the target folder.
This has been baffling me since I have implemented a similar mapping for Oracle Spatial's datatype, which is more complicated yet works great.
Any insight is appreciated.
Thanks.
