Jatmibroker clients start transactions via the JTA and JTS. Jatmibroker-xatmi uses an instance of the class org.jboss.narayana.blacktie.jatmibroker.core.tx.TransactionImpl. TransactionImpl uses the CORBA OTS interface to the transaction manager. For use with AS7 we would like to use the HTTP REST interface to JBossTM. The parent task has already done this for C based clients, this new task is to do the same for Java clients. The requirement only covers the need to start and end transactions (i.e. there is no requirement for supporting enlistment of resources within the transaction).
The C equivalent functionality is located in the files atmibroker-tx/src/main/include/HttpXXX.h
The REST API is packaged as a war and is available by checking out https://svn.jboss.org/repos/labs/labs/jbosstm/trunk/rest-tx
