<DL>
<DD>Called by the servlet container to indicate to a servlet that the 
 servlet is being placed into service.

 <p>The servlet container calls the <code>init</code>
 method exactly once after instantiating the servlet.
 The <code>init</code> method must complete successfully
 before the servlet can receive any requests.

 <p>The servlet container cannot place the servlet into service
 if the <code>init</code> method
 <ol>
 <li>Throws a <code>ServletException</code>
 <li>Does not return within a time period defined by the Web server
 </ol>

getServletConfig</H3>
<PRE>
public <A HREF="../../javax/servlet/ServletConfig.html" title="interface in javax.servlet">ServletConfig</A> <B>getServletConfig</B>()</PRE>
<DL>
<DD>Returns a <A HREF="../../javax/servlet/ServletConfig.html" title="interface in javax.servlet"><CODE>ServletConfig</CODE></A> object, which contains
 initialization and startup parameters for this servlet.
 The <code>ServletConfig</code> object returned is the one 
 passed to the <code>init</code> method. 

 <p>Implementations of this interface are responsible for storing the 
 <code>ServletConfig</code> object so that this 
 method can return it. The <A HREF="../../javax/servlet/GenericServlet.html" title="class in javax.servlet"><CODE>GenericServlet</CODE></A>
 class, which implements this interface, already does this.

                    java.io.IOException</PRE>
<DL>
<DD>Called by the servlet container to allow the servlet to respond to 
 a request.

 <p>This method is only called after the servlet's <code>init()</code>
 method has completed successfully.
 
 <p>  The status code of the response always should be set for a servlet 
 that throws or sends an error.

 
 <p>Servlets typically run inside multithreaded servlet containers
 that can handle multiple requests concurrently. Developers must 
 be aware to synchronize access to any shared resources such as files,
 network connections, and as well as the servlet's class and instance 
 variables. 
 More information on multithreaded programming in Java is available in 
 <a href="http://java.sun.com/Series/Tutorial/java/threads/multithreaded.html">
 the Java tutorial on multi-threaded programming</a>.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>req</CODE> - the <code>ServletRequest</code> object that contains

<DT><B>Throws:</B>
<DD><CODE><A HREF="../../javax/servlet/ServletException.html" title="class in javax.servlet">ServletException</A></CODE> - if an exception occurs that interferes

<A NAME="getServletInfo()"><!-- --></A><H3>
getServletInfo</H3>
<PRE>
public java.lang.String <B>getServletInfo</B>()</PRE>
<DL>
<DD>Returns information about the servlet, such
 as author, version, and copyright.
 
 <p>The string that this method returns should
 be plain text and not markup of any kind (such as HTML, XML,
 etc.).
<P>
<DD><DL>

<DT><B>Returns:</B><DD>a <code>String</code> containing servlet information</DL>
</DD>
</DL>
<HR>

<A NAME="destroy()"><!-- --></A><H3>
destroy</H3>
<PRE>
public void <B>destroy</B>()</PRE>
<DL>
<DD>Called by the servlet container to indicate to a servlet that the
 servlet is being taken out of service.  This method is
 only called once all threads within the servlet's
 <code>service</code> method have exited or after a timeout
 period has passed. After the servlet container calls this 
 method, it will not call the <code>service</code> method again
 on this servlet.

 <p>This method gives the servlet an opportunity 
 to clean up any resources that are being held (for example, memory,
 file handles, threads) and make sure that any persistent state is
 synchronized with the servlet's current state in memory.
