Title: Java/J2EE Consultant

Service Virtualization comes to the rescue by eliminating external system dependencies through the creation of a virtual or mock system that offers the necessary services. The system initiates a request to the virtual system, which then provides an appropriate response. Additionally, the system transmits a payload to a topic, and the virtual system asynchronously delivers responses through various topics back to the calling system.

Core DMS can generate synthetic text data, which is utilized to produce synthetic responses within the virtual system prior to transmitting them to the calling system. DMS to examine the request payload, extract data from it, and save it as in-memory files (virtual files).
