EGL uses a test server to invoke services from the service logic in your workspace rather than from a deployment site. The server is based on Jetty technology, which is described here:
workspace://project_name/fully_qualified_service_name
The test server in this example is specific to MyProject01.
The server relies on the detail in the EGL deployment descriptors that are used at development time. The server also relies on the classpath that is specific to the project.
The Eclipse debug tooling might fail or behave incorrectly in response to some kinds of hot code replace.
You do not start a test server manually. However, you might need terminate a test server; for example, if your preference settings allow the server to continue in the cases just described.
