Integrating transaction processing system interfaces with event-driven polyglot runtime modules

A computer program product, comprising:

• a computer readable storage medium;
• and
• a computer readable program code stored in the computer readable storage medium, the computer readable program code containing instructions that are executed by a central processing unit (CPU) of a computer system to implement a method of providing transactional operations in an event-driven polyglot language runtime environment, the method comprising the steps of:
• the computer system exposing native functionalities of a transaction processing system as interfaces to multiple languages and frameworks in the event-driven polyglot language runtime environment, the native functionalities providing the transactional operations;
• the computer system generating application programming interfaces (APIs) for the event-driven polyglot language runtime environment;
• via the APIs, the computer system calling the transactional operations from modules within the event-driven polyglot language runtime environment;
• based in part on the native functionalities of the transaction processing system being exposed and the transactional operations being called from the modules within the event-driven polyglot language runtime environment via the APIs, the computer system integrating the transaction processing system with the modules within the event-driven polyglot language runtime environment;
• the computer system generating an XA resolution thread that performs open operations with respective resource managers (RMs) to prepare the RMs for use in the transaction;
• the computer system maintaining a pool of connections for respective RMs;
• the computer system receiving a request for a connection object for an RM included in the RMs, the request for the connection object being received from an application executing in the event-driven polyglot language runtime environment;
• in response to the step of receiving the request for the connection object, the computer system selecting a connection object for the RM from the pool and sending to the application the selected connection object for the RM;
• the computer system mapping a connection object created by the application with the connection object that was sent to the application;
• the computer system receiving from the application a request for a transaction object that performs a transaction in the transaction processing system, and in response, sending the transaction object to the application which performs an operation of the RM;
• the computer system mapping the transaction object with a transaction identifier that identifies a resolution of the transaction;
• the computer system logging data about recovery operations performed by the application;
• and
• the computer system receiving from the application a request to perform a commit or a rollback of the transaction, and in response, performing the commit or the rollback of the transaction by using the XA resolution thread.
