How to create new transaction when getTransaction is returning -1 . i am using java to create a action which would be called through rest api

This is described in NSO documentation, book Development, chapter Java API overview/MAAPI:

    maapi.startUserSession("admin",
                           InetAddress.getByName("localhost"),
                           "maapi",
                           new String[] {"admin"},
                           MaapiUserSessionFlag.PROTO_TCP);

    int th = maapi.startTrans(Conf.DB_RUNNING,
                              Conf.MODE_READ_WRITE);

Your needs may vary a bit, e.g. you may want to use the username from the action context, or you need READ_ONLY transaction, etc.

I want to take the opportunity to warn a little against starting user sessions from code. Because in this case you are hardcoding the username ‘admin’ into your code. This will work in local installs, but not by default in system installs. If you want to start user-sessions you need to make sure that the code always uses an appropriate user-name!
