Service (Apache Tomcat 10.1.48 API Documentation)
Description: declaration: package: org.apache.catalina, interface: Service

# Interface Service

All Superinterfaces:
  `Lifecycle`

All Known Implementing Classes:
  `StandardService`

public interface Service extends Lifecycle
A Service is a group of one or more Connectors that share a single Container to process their incoming requests. This arrangement allows, for example, a non-SSL and SSL connector to share the same population of web apps.

A given JVM can contain any number of Service instances; however, they are completely independent of each other and share only the basic JVM facilities and classes on the system class path.

- ## Method Details

  - ### getContainer

    Engine getContainer()
    Returns:
      the `Engine` that handles requests for all `Connectors` associated with this Service.

  - ### setContainer

    void setContainer(Engine engine)
    Set the `Engine` that handles requests for all `Connectors` associated with this Service.
    Parameters:
      `engine` - The new Engine

  - ### getName

    String getName()
    Returns:
      the name of this Service.

  - ### setName

    void setName(String name)
    Set the name of this Service.
    Parameters:
      `name` - The new service name

  - ### getServer

    Server getServer()
    Returns:
      the `Server` with which we are associated (if any).

  - ### setServer

    void setServer(Server server)
    Set the `Server` with which we are associated (if any).
    Parameters:
      `server` - The server that owns this Service

  - ### getParentClassLoader

    ClassLoader getParentClassLoader()
    Returns:

    void setParentClassLoader(ClassLoader parent)
    Set the parent class loader for this service.
    Parameters:
      `parent` - The new parent class loader

  - ### getDomain

    String getDomain()
    Returns:
      the domain under which this container will be / has been registered.

  - ### addConnector

    void addConnector(Connector connector)
    Add a new Connector to the set of defined Connectors, and associate it with this Service's Container.
    Parameters:
      `connector` - The Connector to be added

    Connector[] findConnectors()
    Find and return the set of Connectors associated with this Service.
    Returns:
      the array of associated Connectors

  - ### removeConnector

    void removeConnector(Connector connector)
    Remove the specified Connector from the set associated from this Service. The removed Connector will also be disassociated from our Container.
    Parameters:
