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-implemented method for problem determination for cooperating web services, the method comprising:
executing, by one or more computer processors, a debug script wherein the debug script sets a list of breakpoints on a list of known web services;
discovering, by the one or more computer processors, a plurality of web services based on a web service discovery mechanism;
connecting, by the one or more computer processors, by a debug daemon, with a first debug probe to set a breakpoint on a first web service;
receiving, by the one or more computer processors, 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;
invoking, by the one or more computer processors, a breakpoint handler function for the first web service;
sending, by the one or more computer processors, commands to a second debug probe, wherein the commands are forwarded to a second web service based on the breakpoint; and
closing, by the one or more computer processors, responsive to the breakpoint handler function having run to completion, the debug session with the second web service.

2. The computer-implemented method of claim 1 , further comprising:
providing, by the one or more computer processors, the debug daemon, wherein the debug daemon listens for a debug connection.

3. The computer-implemented method 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-implemented method 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-implemented method 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.

6. The computer-implemented method of claim 4 , wherein context information is available to the invoked breakpoint handler function as function parameters.

7. The computer-implemented method 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.
