I have a solution for Java/JPA/eclipselink/oracle when insert a long xml string (>4000) into a XMLTYPE column at Insert XML with more than 4000 characters into a Oracle XMLTYPE column. For clarity, include the same contents here in case the link not working

You need to convert xml string for more than 4000 charcaters into SQLXML type first.

Environment: jpa 2.1.0, eclipselink 2.5.2, oracle db 11gr2

SQL:

CREATE TABLE "XMLTEST"
( "ID" NUMBER(10,0) NOT NULL ENABLE, 
  "DESCRIPTION" VARCHAR2(50 CHAR) NOT NULL ENABLE, 
  "XML_TXT" "XMLTYPE" NOT NULL ENABLE
);

INSERT INTO XMLTEST (ID, DESCRIPTION, XML_TXT) VALUES (101, 'XML DATA', 'TEST');
COMMIT;

DROP TABLE "XMLTEST";

Java Code

String sql = "INSERT INTO XMLTEST (ID, DESCRIPTION, XML_TXT) VALUES (?, ?, ?)";
String xmlDataStr = "test..."; // a long xml string with length > 4000 characters
Connection con = getEntityManager().unwrap(Connection.class);
SQLXML sqlXml = con.createSQLXML();
sqlXml.setString(xmlDataStr);

Java code - use PreparedStatement

PreparedStatement pstmt = con.prepareStatement(sql);
pstmt.setLong(1, 201);
pstmt.setLong(2, "Long XML Data");
pstmt.setSQLXML(3, sqlXml);
pstmt.execute();

Java code - use native query instead of PreparedStatement

Query query = getEntityManager().createNativeQuery(sql);
query.setParameter(1, 301);
query.setParameter(2, "Long XML Data");
query.setParameter(3, sqlXml);
query.executeUpdate();
