When following the JTA 1.0.1B spec [1] while implementing my resource adapter (XAResource) around the Commons Transaction FileResourceManager I came across another issue:
XAResource has a method "public Xid[] recover(int flag)". Following is written in the spec's section "3.4.8 Failures recovery": "For each resource manager, the Transaction Manager uses the XAResource.recover method to retrieve the list of transactions that are currently in a prepared or heuristically completed state. [..] Because XAResource objects are not persistent across system failures, the Transaction Manager needs to have some way to acquire the XAResource objects that represent the resource managers which might have participated in the transactions prior to the system failure. For example, a Transaction Manager might, through the use of the JNDI lookup mechanism and cooperation from the application server, acquire an XAResource object representing each of the Resource Manager configured in the system. The Transaction Manager then invokes the XAResource.recover method to ask each resource manager to return any transactions that are currently in a prepared or heuristically completed state. It is the responsibility of the Transaction Manager to ignore transactions that do not belong to it." This means I need a way to retrieve a list of transaction IDs to be recovered, which the Commons Transaction ResourceManager interface does not provide at the moment. Its recover() method does not provide it. Would it be possible to change the method though this changes the interface?
