[eclipselink-users] Foreign key as String

[Thierry Peng <peng@xxxxxxx>]

Hi

Is there a way to use a String (varchar column) as a foreign key for a 
mantytoone relation in eclipselink? I'm running always in a

java.lang.NumberFormatException: For input string: "1-1-1"
    at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
    at java.lang.Integer.parseInt(Integer.java:456)
    at java.lang.Integer.<init>(Integer.java:620)
    at org.eclipse.persistence.internal.helper.ConversionManager.convertObjectToInteger(ConversionManager.java:521)
    at org.eclipse.persistence.internal.helper.ConversionManager.convertObject(ConversionManager.java:113)

with the following annotations:

@ManyToOne(fetch = FetchType.LAZY)
 @JoinColumn(name = "ID_LOG", nullable = false)
 public X getX()

and

@Column(name = "ID_LOG", unique = true, nullable = false, length = 10)
 public String getIdLog()

greetings
