10.3. Accessing the solver using the REST API

After deploying or re-creating the sample solver, you can access it using the REST API.

You must register a solver instance using the REST API. Then you can supply data sets and retrieve optimized solutions.

Prerequisites

The employee rostering project is set up and deployed according to the previous sections in this document. You can either deploy the sample project, as described in 「Deploying the employee rostering sample project in Business Central」, or re-create the project, as described in 「Re-creating the employee rostering sample project」.

You must register the solver instance using the REST API before you can use the solver.

Each solver instance is capable of optimizing one planning problem at a time.

Procedure

Create a HTTP request using the following header:

authorization: admin:admin
X-KIE-ContentType: xstream
content-type: application/xml

Register the Solver using the following request:
PUT
http://localhost:8080/kie-server/services/rest/server/containers/employeerostering_1.0.0-SNAPSHOT/solvers/EmployeeRosteringSolver
Request body
<solver-instance> <solver-config-file>employeerostering/employeerostering/EmployeeRosteringSolverConfig.solver.xml</solver-config-file> </solver-instance>
