Abstract

In an approach to problem determination for cooperating web services, a computing device executes a debug script. The computing device discovers one or more web services based on a web service discovery mechanism. The computing device connects, by the debug daemon, with a debug probe to set a breakpoint on a web service. The computing device receives a file containing connection parameters. The computing device initiates a debug session with the web service using a designated connection channel. The computing device invokes a breakpoint handler function for the web service. The computing device sends commands to the debug probe, which forwards the debug commands to the web service. The computing device closes the debug session with the web service when the breakpoint handler function has run to completion.

First claim

What is claimed is:

1. A computer program product for problem determination for cooperating web services, the computer program product comprising:
one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
program instructions to execute a debug script, wherein the debug script sets a list of breakpoints on a list of known web services;
program instructions to discover one or more web services based on a web service discovery mechanism;
program instructions to connect, by a debug daemon, with a first debug probe to set a breakpoint on a first web service;
program instructions to receive a file containing connection parameters, wherein the connection parameters are used to initiate a debug session with the first web service using a designated connection channel;
program instructions to invoke a breakpoint handler function for the first web service;
program instructions to send commands to a second debug probe, wherein the commands are forwarded to a second web service based on the breakpoint; and
program instructions to close, responsive to the breakpoint handler function having run to completion, the debug session with the second web service.

2. The computer program product of claim 1 , further comprising:
program instructions to provide the debug daemon, wherein the debug daemon listens for a debug connection.

3. The computer program product of claim 2 , wherein the one or more web services have names, wherein the debug script knows the names of the one or more web services, and wherein additional details concerning the one or more web services are handled by the web service discovery mechanism.

4. The computer program product of claim 2 , wherein each breakpoint is associated with a breakpoint handler function which is invoked when the associated breakpoint is hit.

5. The computer program product of claim 4 , wherein context information is available to the invoked breakpoint handler function as function parameters.

6. The computer program product of claim 1 , wherein the first debug probe sets the breakpoint based on accessing a service declaration table and using language adapters to set the breakpoint on a correct entry point.

7. The computer program product of claim 1 , wherein the first debug probe and the second debug probe act as proxies after a debug connection has been established between a client and a host of the first web service and the second web service, respectively.

8. A computer system for problem determination for cooperating web services, the computer system comprising:
one or more processors;
one or more computer readable storage media; and
program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
program instructions to execute a debug script, wherein the debug script sets a list of breakpoints on a list of known web services;
program instructions to discover one or more web services based on a web service discovery mechanism;
program instructions to connect, by a debug daemon, with a first debug probe to set a breakpoint on a first web service;
program instructions to receive a file containing connection parameters, wherein the connection parameters are used to initiate a debug session with the first web service using a designated connection channel;
program instructions to invoke a breakpoint handler function for the first web service;
program instructions to send commands to a second debug probe, wherein the commands are forwarded to a second web service based on the breakpoint; and
program instructions to close, responsive to the breakpoint handler function having run to completion, the debug session with the second web service.

9. The computer system of claim 8 , further comprising:
program instructions to provide the debug daemon, wherein the debug daemon listens for a debug connection.

10. The computer system of claim 9 , wherein the one or more web services have names, wherein the debug script knows the names of the one or more web services, and wherein additional details concerning the one or more web services are handled by the web service discovery mechanism.

11. The computer system of claim 9 , wherein each breakpoint is associated with a breakpoint handler function which is invoked when the associated breakpoint is hit.

12. The computer system of claim 11 , wherein context information is available to the invoked breakpoint handler function as function parameters.

13. The computer system of claim 8 , wherein the first debug probe sets the breakpoint based on accessing a service declaration table and using language adapters to set the breakpoint on a correct entry point.

14. The computer system of claim 8 , wherein the first debug probe and the second debug probe act as proxies after a debug connection has been established between a client and a host of the first web service and the second web service, respectively.
