  The base class of the generated servlets.

### SERVICE_METHOD_NAME

    public static final java.lang.String SERVICE_METHOD_NAME

  _jspService is the name of the method that is called by HttpJspBase.service(). This is where most of the code generated from JSPs go.

### JSP_FILE

    public static final java.lang.String JSP_FILE

  FIXME Request attribute for `<jsp-file>` element of a servlet definition. If present on a request, this overrides the value returned by `request.getServletPath()` to select the JSP page to be executed.

### SERVLET_CLASS_LOADER

    public static final java.lang.String SERVLET_CLASS_LOADER

  FIXME ServletContext attribute for classpath. This is tomcat specific. Other servlet engines can choose to have this attribute if they want to have this JSP engine running on them.

### K

    public static final int K

  Default size of the JSP buffer.

### DEFAULT_BUFFER_SIZE

    public static final int DEFAULT_BUFFER_SIZE

### PRECOMPILE

    public static final java.lang.String PRECOMPILE
