所有已实现的接口:

java.io.Serializable, java.rmi.Remote, javax.servlet.Servlet, javax.servlet.ServletConfig

public abstract class RemoteHttpServlet
extends javax.servlet.http.HttpServlet
implements java.rmi.Remote

A superclass for any HTTP servlet that wishes to act as an RMI server. RemoteHttpServlet begins listening for RMI calls in its init() method and stops listening in its destroy() method. To register itself it uses the registry on the local machine on the port determined by getRegistryPort(). It registers under the name determined by getRegistryName().

方法详细资料

init

public void init(javax.servlet.ServletConfig config)
          throws javax.servlet.ServletException

Begins the servlet's RMI operations. Causes the servlet to export itself and then bind itself to the registry. Logs any errors. Subclasses that override this method must be sure to first call super.init(config).

指定者:

init 在接口中 javax.servlet.Servlet

覆盖:

init 在类中 javax.servlet.GenericServlet

参数:

config - the servlet config

抛出:

javax.servlet.ServletException - if a servlet exception occurs

destroy

public void destroy()

Halts the servlet's RMI operations. Causes the servlet to unbind itself from the registry. Logs any errors. Subclasses that override this method must be sure to first call super.destroy().

指定者:

destroy 在接口中 javax.servlet.Servlet

覆盖:

destroy 在类中 javax.servlet.GenericServlet

getRegistryName

protected java.lang.String getRegistryName()

Returns the name under which the servlet should be bound in the registry. By default the name is the servlet's class name. This can be overridden with the registryName init parameter.

返回:

the name under which the servlet should be bound in the registry

getRegistryPort

protected int getRegistryPort()

Returns the port where the registry should be running. By default the port is the default registry port (1099). This can be overridden with the registryPort init parameter.

返回:

the port for the registry

bind

protected void bind()

Binds the servlet to the registry. Creates the registry if necessary. Logs any errors.

unbind

protected void unbind()

Unbinds the servlet from the registry. Logs any errors.
