Subject pax-jdbc-config connection pool configuration
Date Mon, 14 May 2018 19:47:50 GMT
Using Karaf  4.2.0, I am trying to configure connection pool using pax-jdbc-config  approach.
 I installed features:

pax-jdbc-mariadb
pax-jdbc-config
pax-jdbc-pool-dbcp2



I dropped a org.ops4j.datasource-responder.cfg file in the etc directory:

osgi.jdbc.driver.name = mariadb
dataSourceName=responder
url = jdbc:mariadb://localhost:3306/responder
user=XXXX
password=XXXX
pool=dbcp2
xa=true
databaseName=responder
jdbc.pool.maxTotal=8


The last line causes this error:

cannot set properties [pool.maxTotal]
java.sql.SQLException: cannot set properties [pool.maxTotal]

How do I configure the various parameters of the connection pool?


Best regards,
