we changed to column from nclob to clob. It works now hovewer we had to clear the values

This works fine.

If you want to use an existing connection


insert(........){

sLogger

OraclePreparedStatement lStmt = null;
String sql = "INSERT INTO FS_CONFIG_ELEMENT FSCE (CONFIG_ID,ELEMENT_ID,SORT_ORDER,LANG_CD,ELEMENT_VALUE,PART_ID,PART_FOOTNOTE_INDICATOR) VALUES (?,?,?,?,?,?,?)";
// Transaction should be started before calling this.
//Should we close this connection or is it the same connection that ODS is using ?
java.sql.Connection lConnection = ((JDBCObjectDataSource)lODS).getConnection();
lStmt = (OraclePreparedStatement)lConnection.prepareStatement(sql);
lStmt.setInt(1, aFSElementBean.getConfigId());
lStmt.setInt(2, aFSElementBean.getElementId());
lStmt.setInt(3, aFSElementBean.getSortOrder());
lStmt.setString(4, aFSElementBean.getLangCd());

//NCLOB or NCHAR or NVARCHAR Column
lStmt.setFormOfUse(5,(short)OraclePreparedStatement.FORM_NCHAR);
lStmt.setString(5, aFSElementBean.getDefaultValue());
lStmt.setInt(6, aFSElementBean.getPartId());
lStmt.setString(7, aFSElementBean.getPartFootNoteInd());

// Execute the query //
lStmt.execute();
sLogger.debug("Inserting ElementBean successful.");
}

// ELEMENT_VALUE here can be NCHAR or NVARCHAR or NCLOB

How do I do this with Hibernate Annotations?

This works great with proxool and Oracle 11g.
I added an annotation to the field and everything seems to be great:
