[ https://issues.jboss.org/browse/JBJCA-1112?page=com.atlassian.jira.plugin... ] Jesper Pedersen commented on JBJCA-1112: ---------------------------------------- A DataSource isn't serializable, but the JCA connection factory, which in this case represents the DataSource instance, has to be. Ideally the JCA connection manager has to be serializable too, but IronJacamar 1.x doesn't implement this contract, since it isn't trivial - f.ex. there can't be any active connections. I'll see if I can find a hack at the JDBC resource adapter level in order to work around this issue. A workaround could be to don't serialize JCA backed resources, and reinject them again during readObject(). -- This message is automatically generated by JIRA.
