[eclipselink-users] UUID eclipselink 2.5.1

[Edward Mann <eclipselink@xxxxxxxxxx>]

Ancoron & others,

I did a UUID converter for Eclipselink 2.4.0, and that was working fine.
Last weekend i decided to upgrade to 2.5.1 as i was working on a new
project. I noticed that my converter class did not work anymore. Also i
am not sure if it is really needed anymore and if e.l 2.5.x supports
uuid conversion out of the box. Granted since i was using a
persistence.xml file from and old project as a template i could have
left things in there that caused my issue. With that said i updated the
converter i had done for 2.4.x to work in 2.5.x. If a converter is not
needed please let me know. Below is the converter.

UUIDConverter.java:

package com.edmann.core;

import java.util.UUID;

import org.eclipse.persistence.internal.helper.DatabaseField;
import org.eclipse.persistence.mappings.DatabaseMapping;
import org.eclipse.persistence.mappings.DirectCollectionMapping;
import org.eclipse.persistence.mappings.converters.Converter;
import org.eclipse.persistence.sessions.Session;

/**
 * Supports mapping of <tt>java.util.UUID</tt> inside JPA entities.
 * 
 * <p>
 * Example usage:
 * <pre>
 * //..
 * import java.util.UUID;
 * import org.ledger.core.UUIDConverter;
 *  //..
 *  
 *  &#064;Entity
 *
&#064;Converter(name="uuidConverter",converterClass=UUIDConverter.class)
 *  public class Elink implements Serializable {
 *  	 &#064;Convert("uuidConverter")
 * 	 &#064;Column(name="elink_id")
 * 	 private UUID elinkId;
 *   //..
 *   }
 *   </pre>
 *   </p>

            field = mapping.getField();

        field.setSqlType(java.sql.Types.OTHER);
        field.setTypeName("java.util.UUID");
        field.setColumnDefinition("uuid");
    }
}


entry in persistence.xml:
<property name="eclipselink.session.customizer"
                    value="com.edmann.core.UUIDSequence" />


Test file Account.java:

/**
 * The persistent class for the account database table.
 * 
 */
@Entity
@Table(name = "account", schema = "edmann")
@Converter(name = "uuidConverter", converterClass = UUIDConverter.class)
public class Account implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @Convert("uuidConverter")
    @UuidGenerator(name = "uuid")
    @Column(name = "acct_id")
    private UUID acctId;

..getters/setters...
}

If this is no longer needed please someone let me know.

Thanks
