I'm not sure if this is the right place for this question, but 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)`:
