I have a java app running in JBoss that uses EclipseLink to persist to a Postgres database. I've added a field with a 'path' datatype to one of the tables but I keep getting the following exception when I try to insert data:
org.postgresql.util.PSQLException: Can't infer the SQL type to use for an instance of org.postgresql.geometric.PGpath. Use setObject() with an explicit Types value to specify the type to use. Here's the table definition: CREATE TABLE schema.table_name ( item_id uuid NOT NULL, item_path path NOT NULL ) The java entity is representing the item_path field as a List<Point> object, and I'm using a converter to map from the List<Point> object to a PGpath object: import org.eclipse.persistence.mappings.DatabaseMapping; import org.eclipse.persistence.mappings.converters.Converter; import org.eclipse.persistence.sessions.Session; import org.postgresql.geometric.PGpath; import java.awt.Point; import java.util.ArrayList; import java.util.List; import static java.sql.Types.OTHER; public class PgPathConverter implements Converter { @Override public boolean isMutable () { return false; } @Override public List<Point> convertDataValueToObjectValue (Object value, Session session) { // Code that converts PGpath to List<Point> } @Override public PGpath convertObjectValueToDataValue (Object value, Session session) { // Code that converts List<Point> to PGpath } @Override public void initialize (DatabaseMapping mapping, Session session) { mapping.getField ().setSqlType (OTHER); } } The entity class is defined as follows: @Entity @Table ( name = "table_name", schema = "schema" ) @Converter ( name = "path", converterClass = PgPathConverter.class ) public class TableName { public TableName () {} private static final long serialVersionUID = 1L; @Column (name = "item_path") @Convert ("path") private List<Point> m_ItemPath; @Id @Column ( name = "item_id", unique = true, nullable = false ) private UUID m_ItemId; public UUID getItemId () { return m_ItemId; } public List<Point> getItemPath () { return m_InkPath; } public void setItemId (UUID itemId) { m_ItemId = itemId; } public void setInkPath (List<Point> itemPath) { m_ItemPath = itemPath; } } Finally, here's the exception I get when I call `EntityManager.persist (entity)`: 18:10:33,789 ERROR [org.jboss.as.ejb3] (http-/0.0.0.0:8080-1) javax.ejb.EJBTransactionRolledbackException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: org.postgresql.util.PSQLException: Can't infer the SQL type to use for an instance of org.postgresql.geometric.PGpath.
