The operation listInUseConnections should be available on CacehdConnectionManager from version 3.2.6. I have just installed 3.2.6 but this operation is not available. I have debug set to true in the transaction-service.xml file in my deploy folder.
Anyone got any ideas why I can't see this operation?
You are not using 3.2.6?
CVS says it was added for 3.2.6RC2 (i.e. before the final release)
