java -Djdk.tls.ephemeralDHKeySize=2048 \ -classpath 'james-server-jpa-app.lib/*:/path/to/driver.jar' \ -javaagent:/root/libs/openjpa-3.1.2.jar \ -Dlogback.configurationFile=/root/conf/logback.xml \ -Dworking.directory=/root/ org.apache.james.JPAJamesServerMain Note that I did add extra instructions on the 3.7.0 release line. - https://github.com/apache/james-project/tree/master/server/apps/jpa-app#using-alternative-jdbc-drivers - https://github.com/apache/james-project/blob/master/server/apps/jpa-app/docker-compose.yml Best regards, Benoit On 04/10/2021 11:06, Jerry Malcolm wrote: > I have a different issue in my migration from spring to jpa-guice.
