error when merge using hibernate 3 and ojdbc 7 [duplicate]

This question already has answers here:
java.lang.ArrayIndexOutOfBoundsException at oracle.jdbc.driver.T4CTTIrxd.readBitVector(T4CTTIrxd.java:135)

Closed 5 years ago.
I get an error when I save my entity using the merge() method from EntityManager. This issue happens when I use Hibernate 3 combined with ojdbc7 12.1.0.2.0 JDBC 4.1, but if I change to ojdbc6 11.2.0.3.0 JDBC 4.0 this error will disappear. Can anyone help to resolve my problem, because I need to use ojdbc7.

Had the same problem using the 12.1.0.2 driver with an Oracle 10g database. It happens apparently when the driver is performing a fetch - querying the database for more rows while scrolling through a ResultSet.
Looks like a nasty bug in the driver as #MarkRotteveel pointed out in his comment.
Incrementing the fetchSize property worked well as a temporary workaround to avoid the issue, forcing the driver to retrieve all results at once with no data left to fetch, but it is not a long-term solution and may have a large negative impact on performance/memory depending on the size and amount of data the query is retrieving.
If you're using Hibernate, try to identify the query that is raising the exception (use for instance hibernate.show_sql), check how many rows does it return and adjust the hibernate.jdbc.fetch_size property accordingly.
A non-zero value determines the JDBC fetch size (calls Statement.setFetchSize()).
Or try using a different version of the driver. This exception didn't happen with 12.1.0.1 if I remember correctly.

If you are using Oracle 12c, try using Oracle12cDialect for the dialect.

The error message states that you try to insert a new record into your table without filling a field which is required to be filled.
In your case, that field seems to be your primary key or so called "id" which is normally auto-generated by incrementing it. So if you have 3 records, they have id 1, 2 and 3.
In Hibernate, you can do that by adding #GeneratedValue(strategy=GenerationType.AUTO)
In MySQL, this automatically results in auto incrementing your id field. In other database servers, this can also result in having a seperate table for id's.
For further information about GeneratedValue, just take a look into Hibernate documentation: http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#entity-mapping-identifier
I hope my post helped.

this appears in my error output on screen
could not update: [com.company.project.dataobject.PSDBusinessAssociate#18962]; nested exception is org.hibernate.exception.SQLGrammarException: could not update: [com.company.project.dataobject.PSDBusinessAssociate#18962]
so my question is what exactly does this error mean and what causes this error to occur?

This looks like the SQL that hibernate is generating isn't valid. This can often mean that your mappings are incorrect (such as incorrect column/table names). A good way to debug SQL Grammer exceptions is to set hibernate.show_sql=true and hibernate.format_sql=true in your SessionFactory. Hibernate will output generated sql to the console for you to verify.

Have you tried rebuilding your database through a Hibernate command? (I know Netbeans allows you to do this, dunno if it runs an ant script behind the scenes...) and seeing if it works?
Maybe someone edited the database manually without you knowing (or you yourself!) and Hibernate finds a table structure different than it is expecting when accessing the database...

Exception in Hibernate 'Cannot Release Connection'?

connection handling in hibernate is the internal handling we don't explicitly release or close the connection.
I can't understand how to resolve this issue..

Finally I got the solution. I solved this problem by setting some additional configuration for by database.
Here is the detailed link: http://tomcat.apache.org/tomcat-7.0-doc/jdbc-pool.html
In nutshell ("testOnBorrow”, “testOnReturn”, “testWhileIdle”) these are the parameters I played with to remove above exception.
Above exception show at some point of time our database connection object get invalidated somehow. But these setting helps us to keep check on our database connection.
Cheers :)
