Abstract

Code compatibility provisions are provided. These may include identifying coding that is incompatible with a rule-based environment, searching replacement code solutions for compatible code and identifying a replacement code solution, manipulating the identified incompatible code using the identified replacement code solution, and, after manipulating the incompatible code with the replacement code solution, loading the services across a rule-based environment.

Claims

1. A method comprising:

during the process of loading services on a server, identifying coding that is incompatible with a server cluster environment;

searching replacement code solutions for code compatible with a server cluster environment;

identifying a replacement code solution from a network storage within the server cluster environment;

manipulating the identified incompatible code using the identified replacement code solution; and

after manipulating the incompatible code with the replacement code solution, to render the incompatible code compatible, loading the services, with the now compatible code, across a cluster server environment.

2. The method of claim 1 wherein the identified code is bytecode and wherein the replacement code is bytecode.

3. The method of claim 1 further comprising:

after searching replacement code solutions for code and failing to identify a replacement code solution, seeking replacement code solutions from a different source.

4. The method of claim 3 wherein the different source is a system administrator.

5. The method of claim 1 further comprising:

developing a replacement code solution by calling and applying a bytecode manipulation to remove incompatibilities within the identified incompatible code.

6. The method of claim 1 further comprising:

providing code identified as incompatible to a system administrator; and

checking for instructions to disregard a replacement code solution for the code identified as incompatible to the system administrator.

7. The method of claim 1 wherein identifying coding includes considering bytecode and wherein the bytecode is presented to the class loader of a primary server.

8. A computer method comprising:

at a computer, identifying program application coding, during the process of loading services to a server cluster environment, that is incompatible with a server cluster environment;

at the computer, searching replacement code solutions for program application code identified as compatible with a server cluster environment;

at the computer, identifying a replacement code solution from a network storage within the server cluster environment;

manipulating the identified incompatible program application code using the identified replacement code solution; and

at the computer, after manipulating the incompatible program application code with the replacement code solution, to render the identified incompatible program application code compatible, loading the services, with the now compatible program application code, across a cluster server environment.

9. The computer method of claim 8 wherein the identified program application code is bytecode and wherein the replacement code is bytecode.

10. The computer method of claim 8 storing instructions further comprising:

after searching replacement code solutions for the identified incompatible program application code and failing to identify a replacement code solution, seeking replacement program application code solutions from a different source.

11. The computer method of claim 10 wherein the different source is a system administrator.

12. The computer method of claim 8 further comprising:

developing a replacement code solution by calling and applying a bytecode manipulation.

13. The computer method of claim 8 further comprising:

providing program application code identified as incompatible to a system administrator; and

checking for instructions to disregard a replacement code solution for the program application code identified as incompatible to the system administrator.

14. A computer method comprising:

at a computer, receiving a service request and identifying program application code of the implementation methodology for the service request;

at the computer, employing a class loader to access bytecode of the program application code of the implementation methodology received for the service request;

presenting the bytecode of the program application code to the custom class loader;

identifying bytecode of the program application code that is incompatible with a cluster server environment;

manipulating identified incompatible bytecode of the program application code to become compatible with a cluster server environment using a replacement code solution within the cluster server environment; and

deploying manipulated bytecode of the program application code to a cluster of servers for loading across the cluster of servers.

15. The method of claim 14 wherein the steps performed further comprise:

flagging incompatible program application code for manual manipulation by a user; and

at the computer, receiving manually manipulated program application code from a user before deploying manipulated bytecode to the cluster of servers for loading across the cluster of servers.
