[jira] Commented: (JCR-890) concurrent read-only access to a session
[ https://issues.apache.org/jira/browse/JCR-890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12524166 ] Padraic Hannon commented on JCR-890: I think this is similar to the discussion from JCR-1050. Perhaps we need a larger effort to look at synchronization within the lower levels of Jackrabbit? concurrent read-only access to a session Key: JCR-890 URL: https://issues.apache.org/jira/browse/JCR-890 Project: Jackrabbit Issue Type: Improvement Components: core Reporter: David Nuescheler Assignee: Stefan Guggisberg Even though the JCR specification does not make a statement about Sessions shared across a number of threads I think it would be great for many applications if we could state that sharing a read-only session is supported by Jackrabbit. On many occasions in the mailing lists we stated that there should not be an issue with sharing a read-only session, however I think it has never been thoroughly tested or even specified as a design goal. If we can come to an agreement that this is desirable I think it would be great to start including testcases to validate that behaviour and update the documentation respectively. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
[jira] Commented: (JCR-1100) Support for dynamic mixins
[ https://issues.apache.org/jira/browse/JCR-1100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12523960 ] Padraic Hannon commented on JCR-1100: - I currently have this working for persistence using cglib. However, it requires moving away from pojo's and requires having interfaces defined to create the proxy dynamically. I can upload diffs with the code, however, I think the solution would be to not have to resort to creating interfaces for everything.

However, within the ocm code one cannot readily add mixins dynamically to objects. This feature would allow jcr nodes to be updated with a mixin and ocm to read that node and ensure an object is created correctly. Additionally for a passed in object upon storage the ocm would inspect it and ensure all mixed in object fields are added to the class descriptor. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.

However, from what I can tell the only place where the connection autocommit is explicitly turned off and rollback() and commit() are called is in the method store(ChangeLog). Assuming that one is running in a container and has access to a datasource I would also assume that one has access to a UserTransaction object. If that is the case, rather than using a connection's transaction handling one can delegate the transaction handling to jta.
