JPA: MySQL says table don't exist, but it exist actually

I have the follow script to create the table autolife.log:

CREATE TABLE `log` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `idpoint` int(11) NOT NULL,
  `value` varchar(10) NOT NULL,
  `time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`),
  KEY `fk_point_id` (`idpoint`),
  CONSTRAINT `fk_point_id` FOREIGN KEY (`idpoint`) REFERENCES `point` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB AUTO_INCREMENT=155562 DEFAULT CHARSET=latin2$$

So I use the JPA Tools to create Entity from Tables in Eclipse Indigo:

@Entity
public class Log implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @SequenceGenerator(name="LOG_ID_GENERATOR", sequenceName="SEQUENCE_KEY")
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="LOG_ID_GENERATOR")
    private Integer id;

    private Timestamp time;

    private String value;

    //bi-directional many-to-one association to Point
    @ManyToOne
    @JoinColumn(name="idpoint")
    private Point point;

    public Log() {
    }

    // get's and set's

When I run in my localhost computer, works fine, but when I export the .war and put in production, gives me this error (below you can see the exception generated by the code):

As you can see it says that the table don't exist, but exist I export from my localhost database and import to the production host. But still gives this error:

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'autolife.LOG' doesn't exist

What should I do here ?

cool question. What about 

USE <Database Name>
GO

clause before executing script?

Normally all SP, tables have those 2 lines before execution

Case sensitivity of MySQL table names depends on operating system, I guess that's the cause:

In MySQL, databases correspond to directories within the data directory. Each table within a database corresponds to at least one file within the database directory (and possibly more, depending on the storage engine). Consequently, the case sensitivity of the underlying operating system plays a part in the case sensitivity of database and table names. This means database and table names are not case sensitive in Windows, and case sensitive in most varieties of Unix. One notable exception is Mac OS X, which is Unix-based but uses a default file system type (HFS+) that is not case sensitive. However, Mac OS X also supports UFS volumes, which are case sensitive just as on any Unix.

So, you need to set table name in the correct case explicitly:

@Entity @Table(name = "log")
public class Log implements Serializable { ... }
