Hi all,
I would like to create a queue with ActiveMQ and exploit the persistence. At
the same time I wouldn't use Spring and its world. So I developed an
application like this:
tomee.xml
<Resource id="IndexerQueueJmsResourceAdapter"
type="ActiveMQResourceAdapter">
BrokerXmlConfig = broker:(tcp://localhost:61616)?persistent=true
ServerUrl = vm://localhost
MaximumRedeliveries = 4
DataSource = IndexerQueueDataSource
</Resource>
<Resource id="IndexerQueueDataSource" type="DataSource">
JdbcDriver com.mysql.jdbc.jdbc2.optional.MysqlXADataSource
JdbcUrl jdbc:mysql://localhost:3306/activemq
UserName x
Password x
JtaManaged true
PoolPreparedStatements true
</Resource>
[....]
The persistence was so given by MySQL. This application worked very well,
and I didn't use the file activemq.xml.
But now I would like to move the persistence from MySql to the file system.
So I would like to use KahaDB. The first step was to remove the DataSource
in the ActiveMQResourceAdapter. The application worked good, saving the
messages in the home directory /activemq-data/etc., but the problem is that
I have an exception starting TomEE

Following some form posts, I added
DataSource =
(so without explain the source) in the ActiveMQResourceAdapter and the
exception desappears. However now the messages are not saved.
So the question is: have you any idea to configure the KahaDB persistence
without using Spring?
Thanks a lot
Davide
