stackOverFlowError [message #871620] Mon, 14 May 2012 10:35 Go to next message

Getting a stackoverflow with a onetoone relationship between two entities.
Attached a screen print of the eclipse debug session.

The 2 entities are called CpTransaction and CpTransCoverage.

Field/mapping info for the CpTransaction class entity:

@OneToOne(cascade = CascadeType.ALL, mappedBy = "cpTransaction")
@PrivateOwned
@JoinTable(name = "CP_COVERAGE", joinColumns = @JoinColumn(name = "PARENT_ID", referencedColumnName = "TRANSACTION_ID"))
private CpTransCoverage cpTerrorismCoverage;



Field/mapping info for the CpTransCoverage class entity:

@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "PARENT_ID", nullable = false)
private CpTransaction cpTransaction;

This mapping is not setup correctly - I would hope that hte @JoinTable annotation on the CpTransCoverage cpTerrorismCoverage relationship is ignored, but you should remove it if you wish to have this relationship really 'mappedby' the cpTransaction relationship. Mappedby indicates that all mapping information and control is held in the cpTransaction mapping, which is configured to use its "PARENT_ID" as a foreign key. Please correct this and see if it helps. If it does not, please provide any caching settings you may be using.

You may also want to try a later release - while I don't know of any issues related to this, it will rule out that it has been fixed by refactoring changes.

When I removed the "MappedBy" parm in CpTransaction, I get the following error

I should mention CpTransCoverage extends another class called CpCoverage. Here is some info about that entity.

@Entity
@Table(name = "CP_COVERAGE")
@Converter(name = "boolean", converterClass = com.gmrc.jpa.domain.mappings.converters.BooleanYNConverter.class)
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "COVERAGE_TYPE", discriminatorType = DiscriminatorType.STRING, length = 1)
public class CpCoverage extends BaseDomain {


More info on the CpTransCoverage entity:

@Entity
@DiscriminatorValue(value = "P")
public class CpTransCoverage extends CpCoverage {

After re-reading your post, I think I may have screwed up.

Did you mean for me to remove the:

@JoinTable(name = "CP_COVERAGE", joinColumns = @JoinColumn(name = "PARENT_ID", referencedColumnName = "TRANSACTION_ID"))

line. Or did you mean to remove the "MappedBy" parameter in the @OneToOne annotation ?

I thought removing the JoinTable would be more likely since you have the backpointer using a foriegn key. In the end, all that matters is the object model and the database are aligned - use either the foreign key or the join table but not both for what seems to be the same relationship.
Removing the mappedby means you would have 2 uni-directional and thus independent relationships.

Looking at the error and inheritance you posted though, CP_COVERAGE is not a join table at all, and so the @JoinTable annotation should be removed.

I do not see a "foriegn key" annotation. What am I missing ?

Hello,

@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "PARENT_ID", nullable = false)
private CpTransaction cpTransaction;

sets up the cpTransaction relationship to use the "PARENT_ID" field in the CpTransCoverage table as a foreign key defaulting to the CpTransaction ID field. I would assume that you are trying to setup a CpTransaction->CpTransCoverage back reference that also uses this database foriegn key relationship, in which case the CpTransCoverage cpTerrorismCoverage relation needs to use the mappedby and remove the @jointable annotations. If that is not the case, please describe what you are trying to do.

Best Regards,
Chris

I greatly appreciate your assistance. Unfortunately,
I'm still having the same issue.

After some further googling, I saw a suggestion to move the
annotation code from the member field to the getter method.
Would this maybe help ?

Also saw the @PrimaryKeyJoinColumn annotation and was wondering
about that as well.

Thanks.

Also, on the CP_TRANSACTION entity, we use
@Cache(type=CacheType.NONE, alwaysRefresh = true)

Re: stackOverFlowError [message #873230 is a reply to message #873218] Thu, 17 May 2012 14:57 Go to previous message
Eclipse UserFriend
@Cache(type=CacheType.NONE, alwaysRefresh = true) is what is likely causing the problem. Try removing the type=CacheType.NONE as this is very bad - In conjunction with the alwaysRefresh and the always cascade and the bidirectional relationships, it means when it goes to build one object from the database it will always then have to build the CP_TRANSACTION, which will inturn cause the referenced object to be again rebuilt from the database (since the object being built in the cache). Using CacheType.NONE really should be avoided except in extreme situations. As the javadoc for the setting notes "This cache type should not be used to disable caching, to properly disable caching set the @Cache isolation attribute to ISOLATED."

Hope this helps.

Best Regards,
Chris
