Hi, as we continue to investigate the XA Part we got something new with the classic driver.
If you run a Installation with: <Resource id="name" type="DataSource"> JdbcDriver com.mysql.jdbc.Driver JdbcUrl jdbc:mysql://localhost/database?autoReconnect=true UserName XXXX Password YYYY JtaManaged true </Resource> the server will start to throw exceptions after 2-4 days like this. WARN Transaction - Unable to enlist XAResource org.apache.openejb.resource.jdbc.managed.local.LocalXAResource@747f0739, errorCode: 0 javax.transaction.xa.XAException: Count not turn off auto commit for a XA transaction at org.apache.openejb.resource.jdbc.managed.local.LocalXAResource.start(LocalXAResource.java:67) ~[openejb-core-4.7.0.jar:4.7.0] .....
