Hi,
I am using odmg api with ojb version 0.9.5 in our project
I have a base PersistanceContext class which has static Implementation and Database
instances.
The odmg instace is initialized by the OJB.getInstance() and the database is opened
using
odmg.newDatabase at the
intialization.
Then in the begin transaction method beofre each transaction is created
and started, a database.open with the repository file name is done.
The exception generated is caught and ignored in the case of a Database
already open exception.
Then the transaction is created and begun using the following two lines
tx = odmg.newTransaction() ;
tx.begin() ;
What happens is that after a few invocations I get the following exception
[11/6/02 19:09:10:898 GMT+05:30] 39850c47 SystemOut U (EMBusiness
224 ) Error Opening Database : ignoring - Database is already open
[11/6/02 19:09:10:898 GMT+05:30] 39850c47 SystemOut U
[org.apache.ojb.odmg.TransactionImpl] WARN:
[11/6/02 19:09:10:898 GMT+05:30] 39850c47 SystemOut U TransactionImpl
created with null DatabaseImpl.
[11/6/02 19:09:11:108 GMT+05:30] 39850c47 SystemOut U (EMBusiness
224 ) Error while beggining transaction null
java.lang.NullPointerException
The problem is that just before the warning and exception caused due to
the null databse, I get the database already open exception which is
caught and ignored, when trying to open the database. This database open
statement is the statement just before the new and begin transaction
statements that causes the exception. I just cant understand how these two
can happen together. Can anyone tell me what I am doing wrong.
Thanks in advance.
Regards Jose
