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. An article of manufacture comprising:

a non-volatile computer readable medium, the computer readable medium storing instructions thereon for analyzing programming application code being provided for execution across a cluster of servers, the instructions, which when executed, comprising;

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

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

after searching replacement code solutions, identifying a replacement code solution;

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

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

2. The article of claim 1 wherein the identified program application code is bytecode and wherein the replacement code solution is bytecode.

3. The article of claim 1 storing instructions, which when executed, further comprise:

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.

4. The article of claim 3 wherein the services are loaded onto a server and wherein the different source is a server administrator.

5. The article of claim 1 storing instructions, which when executed further comprise:

developing a replacement code solution by calling and applying an application code compatibility algorithm.

6. The article of claim 1 storing instructions, which when executed, further comprise:

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.

7. The article 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 comprising:

a non-volatile computer readable medium, the computer readable medium storing instructions thereon for analyzing program application code being provided across a cluster of servers, the instructions, which when executed, comprising;

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

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

identifying a replacement code solution;

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

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 of claim 8 wherein the identified program application code is bytecode and wherein the replacement code is bytecode.

10. The computer of claim 8 storing instructions, which when executed, further comprise:

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 of claim 10 wherein the different source is a system administrator.

12. The computer of claim 8 storing instructions, which when executed further comprise:

developing a replacement code solution by calling and applying a code compatibility algorithm.

13. The computer of claim 8 storing instructions, which when executed, further comprise:

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 server comprising:

a processor and related processor storage, the processor configured to carry out program application code which causes the processor to perform steps comprising;

receive a service request and identify program application code of the implementation methodology for the service request;

employ a class loader to access bytecode of the program application code of the implementation methodology received for the service request;

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

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

manipulate identified incompatible bytecode of the program application code to become compatible with a cluster server environment; and

deploy manipulated bytecode of the program application cod to cluster of servers for loading across the cluster of servers.

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

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

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.
