<!-- ======================== Introduction ============================== -->
<!-- This document defines default values for *all* web applications -->
<!-- loaded into this instance of Tomcat. As each application is -->
<!-- deployed, this file is processed, followed by the -->
<!-- "/WEB-INF/web.xml" deployment descriptor from your own -->
<!-- applications. -->
<!-- -->
<!-- WARNING: Do not configure application-specific resources here! -->
<!-- They should go in the "/WEB-INF/web.xml" file in your application. -->
<!-- ================== Built In Servlet Definitions ==================== -->
<!-- The default servlet for all web applications, that serves static -->
<!-- resources. It processes all requests that are not mapped to other -->
<!-- servlets with servlet mappings (defined either here or in your own -->
<!-- web.xml file. This servlet supports the following initialization -->
<!-- parameters (default values are in square brackets): -->
<!-- -->
<!-- debug Debugging detail level for messages logged -->
<!-- by this servlet. [0] -->
<!-- -->
<!-- input Input buffer size (in bytes) when reading -->
<!-- resources to be served. [2048] -->
<!-- -->
<!-- listings Should directory listings be produced if there -->
<!-- is no welcome file in this directory? [true] -->
<!-- -->
<!-- output Output buffer size (in bytes) when writing -->
<!-- resources to be served. [2048] -->
<!-- -->
<!-- readonly Is this context "read only", so HTTP -->
<!-- commands like PUT and DELETE are -->
<!-- rejected? [true] -->
<!-- -->
<!-- readmeFile File name to display with the directory -->
<!-- contents. [null] -->
<!-- -->
<!-- For directory listing customization. Checks localXsltFile, then -->
<!-- globalXsltFile, then defaults to original behavior. -->
<!-- -->
<!-- localXsltFile Make directory listings an XML doc and -->
<!-- pass the result to this style sheet residing -->
<!-- in that directory. This overrides -->
<!-- globalXsltFile[null] -->
<!-- -->
<!-- globalXsltFile Site wide configuration version of -->
<!-- localXsltFile This argument is expected -->
<!-- to be a physical file. [null] -->

<!-- The "invoker" servlet, which executes anonymous servlet classes -->

<!-- it to other patterns as well. The extra path info portion of such a -->
<!-- request must be the fully qualified class name of a Java class that -->
<!-- implements Servlet (or extends HttpServlet), or the servlet name -->
<!-- of an existing servlet definition. This servlet supports the -->
<!-- following initialization parameters (default values are in square -->

<!-- The JSP page compiler and execution servlet, which is the mechanism -->
<!-- used by Tomcat to support JSP pages. Traditionally, this servlet -->
<!-- is mapped to the URL pattern "*.jsp". This servlet supports the -->

<!-- -->
<!-- checkInterval If development is false and reloading is true, -->
<!-- background compiles are enabled. checkInterval -->
<!-- is the time in seconds between checks to see -->
<!-- if a JSP page needs to be recompiled. [300] -->
<!-- -->
<!-- compiler Which compiler Ant should use to compile JSP -->
<!-- pages. See the Ant documentation for more -->
<!-- information. [javac] -->
<!-- -->
<!-- classdebuginfo Should the class file be compiled with -->
<!-- debugging information? [true] -->
<!-- -->
<!-- classpath What class path should I use while compiling -->
<!-- generated servlets? [Created dynamically -->
<!-- based on the current web application] -->
<!-- -->
<!-- development Is Jasper used in development mode (will check -->
<!-- for JSP modification on every access)? [true] -->
<!-- -->
<!-- enablePooling Determines whether tag handler pooling is -->
<!-- enabled [true] -->
<!-- -->
<!-- fork Tell Ant to fork compiles of JSP pages so that -->
<!-- a separate JVM is used for JSP page compiles -->
<!-- from the one Tomcat is running in. [true] -->
<!-- -->
<!-- ieClassId The class-id value to be sent to Internet -->
<!-- Explorer when using <jsp:plugin> tags. -->
<!-- [clsid:8AD9C840-044E-11D1-B3E9-00805F499D93] -->
<!-- -->
<!-- javaEncoding Java file encoding to use for generating java -->
<!-- source files. [UTF8] -->
<!-- -->
<!-- keepgenerated Should we keep the generated Java source code -->
<!-- for each page instead of deleting it? [true] -->
<!-- -->
<!-- mappedfile Should we generate static content with one -->
<!-- print statement per input line, to ease -->
<!-- debugging? [true] -->
<!-- -->
<!-- trimSpaces Should white spaces in template text between -->
<!-- actions or directives be trimmed? [false] -->
<!-- -->
<!-- reloading Should Jasper check for modified JSPs? [true] -->
<!-- -->
<!-- suppressSmap Should the generation of SMAP info for JSR45 -->
<!-- debugging be suppressed? [false] -->
<!-- -->
<!-- dumpSmap Should the SMAP info for JSR45 debugging be -->
<!-- dumped to a file? [false] -->
<!-- False if suppressSmap is true -->
<!-- -->
<!-- genStrAsCharArray Should text strings be generated as char -->
<!-- arrays, to improve performance in some cases? -->
<!-- [false] -->
<!-- -->
<!-- errorOnUseBeanInvalidClassAttribute -->
<!-- Should Jasper issue an error when the value of -->
<!-- the class attribute in an useBean action is -->
<!-- not a valid bean class? [true] -->
<!-- -->
<!-- scratchdir What scratch directory should we use when -->
<!-- compiling JSP pages? [default work directory -->
<!-- for the current web application] -->
<!-- -->
<!-- xpoweredBy Determines whether X-Powered-By response -->
<!-- header is added by generated servlet [false] -->
<!-- -->
<!-- If you wish to use Jikes to compile JSP pages: -->
<!-- Set the init parameter "compiler" to "jikes". Define -->
<!-- the property "-Dbuild.compiler.emacs=true" when starting Tomcat -->
<!-- by adding the above to your CATALINA_OPTS environment variable. -->
<!-- If you get an error reporting that jikes can't use UTF8 encoding, -->
<!-- try setting the init parameter "javaEncoding" to "ISO-8859-1". -->

<!-- webAppRootDir + File.separator + this prefix. -->
<!-- [WEB-INF/cgi] -->
