Abstract

A technique for operating a computer system to support an application, a first application server environment, and a second application server environment includes intercepting a work request relating to the application issued to the first application server environment prior to execution of the work request. A thread adapted for execution in the first application server environment is created. A context is attached to the thread that non-disruptively modifies the thread into a hybrid thread that is additionally suitable for execution in the second application server environment. The hybrid thread is returned to the first application server environment.

First claim

1 . A computer system configured to support an application, a first application server environment, and a second application server environment, the system comprising:
a request interceptor component configured to intercept a work request relating to the application issued to the first application server environment prior to execution of the work request; an executor component configured to, responsive to the request interceptor component, create a thread adapted for execution in the first application server environment; a thread dispatcher component configured to, responsive to the executor component, attach a context to the thread to non-disruptively modify the thread into a hybrid thread that is additionally suitable for execution in the second application server environment; and a catcher component configured to, responsive to the thread dispatcher component, return the hybrid thread to the first application server environment.

2 . The computer system of claim 1 , wherein the hybrid thread is operable to execute in the first application server environment and in the second application server environment without requiring modification of the first and second application server environments.

3 . The computer system of claim 2 , wherein the hybrid thread comprises first data that is only visible to a server in the first application server environment and second data that is only visible to another server in the second application server environment.

4 . The computer system of claim 1 , wherein the first application server environment and the second application server environment are incompatible in their program execution models.

5 . The computer system of claim 4 , wherein only one of the first application server environment or the second application server environment is a procedural program environment.

6 . The computer system of claim 4 , wherein only one of the first application server environment or the second application server environment is an object-oriented program environment.

7 . The computer system of claim 1 , wherein the context comprises transactional control data of one of the application server environments.

8 . The computer system of claim 1 , wherein the context comprises security control data of one of the application server environments.

9 . The computer system of claim 1 , wherein the context comprises monitoring control data of one of the application server environments.

10 . The computer system of claim 1 , wherein the context comprises diagnostic tracing control data of one of the application server environments.

11 . The computer system of claim 1 , wherein the context comprises data enabling access to an application programming interface of one of the application server environments.

12 . A method of operating a computer system to support an application, a first application server environment, and a second application server environment, the method comprising:
intercepting, by a request interceptor component executing on the computer system, a work request relating to the application issued to the first application server environment prior to execution of the work request; responsive to the request interceptor component, creating, using the computer system, a thread adapted for execution in the first application server environment by an executor component; responsive to the executor component, attaching to the thread, by a thread dispatcher component executing on the computer system, a context to non-disruptively modify the thread into a hybrid thread that is additionally suitable for execution in the second application server environment; and responsive to the thread dispatcher component, returning the hybrid thread to the first application server environment by a catcher component executing on the computer system.

13 . The method of claim 12 , wherein the hybrid thread is operable to execute in the first application server environment and the second application server environment without requiring modification of the first and second application server environments.

14 . The method of claim 13 , wherein the hybrid thread comprises first data visible to a server only in the first application server environment and second data visible to another server only in the second application server environment.

15 . The method of claim 12 , wherein the first application server environment and the second application server environment are incompatible in their program execution models.

16 . The method of claim 15 , wherein only one of the first application server environment or the second application server environment is a procedural program environment.

17 . The method of claim 15 , wherein only one of the first application server environment or the second application server environment is an object-oriented program environment.

18 . The method of claim 12 , wherein the context comprises transactional control data of one of the application server environments, security control data of one of the application server environments, monitoring control data of one of the application server environments, diagnostic tracing control data of one of the application server environments, and/or data enabling access to an application programming interface of one of the application server environments.
