Simultaneous global transaction and local transaction management in an application server

A computer-implemented method, comprising:

• managing a first transaction, from a first application component on a single application server, with a first data source as a local transaction;
• managing a second transaction, from a second application component on the single application server, with a second data source as a global transaction, wherein the second transaction was initially started as a global transaction;
• and
• wherein a same application server instance of the single application server runs both the first application component and the second application component, and wherein the same application server instance of the single application server centrally manages both the local transaction and the global transaction concurrently, wherein the local transaction and the global transaction are independent of one another.

A storage medium storing program instructions, wherein the program instructions are computer-executable to:

• manage a first transaction, from a first application component on a single application server, with a first data source as a local transaction;
• manage a second transaction, from a second application component on the single application server, with a second data source as a global transaction, wherein the second transaction was initially started as a global transaction;
• and
• wherein a same application server instance of the single application server runs both the first application component and the second application component, and wherein the same application server instance of the single application server centrally manages both the local transaction and the global transaction concurrently, wherein the local transaction and the global transaction are independent of one another.
