Class LogbackConfigServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

ch.qos.logback.ext.spring.web.LogbackConfigServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class LogbackConfigServlet
extends javax.servlet.http.HttpServlet

Bootstrap servlet for custom Logback initialization in a web environment. Delegates to LogbackWebConfigurer (see its javadoc for configuration details).

WARNING: Assumes an expanded WAR file, both for loading the configuration file and for writing the log files. If you want to keep your WAR unexpanded or don't need application-specific log files within the WAR directory, don't use Logback setup within the application (thus, don't use LogbackConfigListener or LogbackConfigServlet). Instead, use a global, VM-wide Logback setup (for example, in JBoss) or JDK 1.4's java.util.logging (which is global too).

Note: This servlet should have a lower load-on-startup value in web.xml than ContextLoaderServlet, when using custom Logback initialization.

Note that this class has been deprecated for containers implementing Servlet API 2.4 or higher, in favor of LogbackConfigListener.
According to Servlet 2.4, listeners must be initialized before load-on-startup servlets. Many Servlet 2.3 containers already enforce this behavior (see ContextLoaderServlet javadocs for details). If you use such a container, this servlet can be replaced with LogbackConfigListener. Else or if working with a Servlet 2.2 container, stick with this servlet.

Method Detail

init

public void init()

Overrides:

init in class javax.servlet.GenericServlet

destroy

public void destroy()

Specified by:

destroy in interface javax.servlet.Servlet

Overrides:

destroy in class javax.servlet.GenericServlet

getServletInfo

public String getServletInfo()

Specified by:

getServletInfo in interface javax.servlet.Servlet

Overrides:

getServletInfo in class javax.servlet.GenericServlet

service

public void service(javax.servlet.http.HttpServletRequest request,
           javax.servlet.http.HttpServletResponse response)
             throws IOException

This should never even be called since no mapping to this servlet should ever be created in web.xml. That's why a correctly invoked Servlet 2.3 listener is much more appropriate for initialization work ;-)

Overrides:

service in class javax.servlet.http.HttpServlet

Throws:

IOException
