Automatic Startup of Programs

Question

Well, I have two programs one written in JAVA that queries a database and and generates an xml, and another written in C++ that traverses the xml generated by the java program. I wonder if there is a way to create a service or something of the kind for them to run in a certain period, by will be installed on a machine as server. I thought of something like creating a . bat to run both and then if it is possible to turn this bat into a service. As a beginner I would like suggestions.
