I'm a newbie, so forgive me if I'm not asking the question the right
way.
I have a join table in my DB :
+-------------+------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+------------------+------+-----+---------+-------+
| showId | int(11) unsigned | NO | PRI | | |
| inputFileId | int(11) unsigned | NO | PRI | | |
+-------------+------------------+------+-----+---------+-------+
where showId and inputFileID are PKs in the show table and inputfile
table.
In my code for the InputFile class :
@ManyToOne
@JoinTable(name="Show2InputFile",
joinColumns = @JoinColumn(name="inputFileId"),
inverseJoinColumns = @JoinColumn(name="showId"))
public Show getShow() {
return show;
}
When JPA is instrumenting my classes, it complains :
Caused by: <openjpa-1.1.0-SNAPSHOT-r420667:588533 fatal user error>
org.apache.openjpa.persistence.ArgumentException: You have supplied
columns for "com.joost.model.logistics.InputFile.show<element:class
java.lang.Object>", but this mapping cannot have columns in this
context.
I don't quite understand the error. I use this same thing elsewhere
(I think) w/o a problem. Can someone give me a hint?
