hi,

I have just migrated my Hibernate code from 3.1.3 to 3.3.1 (one that comes default with Jboss 5.1.0 GA).

I have a simple class, Mapping and execution code, this code works fine with earlier version but in latter, it throws exception.

I have changed dialect from Oracle9Dialect to Oracle9iDialect (still getting same exception).

In this particular application.functionality I am connecting to 2 different db, for this I have made changes in jbossts-properties.xml file. So not getting any session/transaction related exception, anymore.


I am struggling with this error for last 2-3 days, I have tried changing datatype of class attribute from primitive to Object, but not luck thr.


Bean Class (class has getter/setter as well. I have changes data type from int to Integer, but in both cases same exception).
_________

public class IDWSetupAuditLog
implements Serializable
{
private Integer auditId = 0;
private Integer tableId = 0;
private String changeReqId;
private String changeReqName;
private Integer changeImplId = 0;
private String changeImplName;
private String changeDetail;
private String changeType;
private String changeReasonDesc;
private Date lastUpdateDt;
}

Mapping

Exception is coming in following code

this.log.debug("Begin of EventDAO : insertAuditData()");
try

session.save(auditLog);/////------------->This line throws following exception
session.flush();
session.clear();

Resolved it,

No need to change any setting any where, but just the one.

session = session.getSession(EntityMode.POJO);

by default its DynaMap.

Hu? The default is definitely POJO, I guess you're having some configuration file laying around which you didn't spot.

hi,

Surely not from my java file.

may be from conf file if you are said so. But, can you tell me which conf file can lead to this type of behavior?

there must be some hibernate.properties file around having an option like "hibernate.default_entity_mode" (see http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html_single/#configuration-optional-properties).
Configuration file can be in other formats, like XML. I'd use a filesystem search tool for "dynamic-map" or "dom4j" to find where it's hiding in your classpath. maybe you have another jar on the classpath which contains it, so make sure to search inside jars as well.

you are super awesome

it was
<property name="hibernate.default_entity_mode">dynamic-map</property>

i changed it to
<property name="hibernate.default_entity_mode">pojo</property>

I'm glad it helped. Just make sure you don't use configuration parameters which you don't know what their effect will be. reading the manual might help as well ;)
