Examples with ServletContext javax.servlet.ServletContext used on opensource projects

Example 1 with ServletContext

use of javax.servlet.ServletContext in project jetty.project by eclipse.

the class Invoker method init.

/* ------------------------------------------------------------ */
public void init() {
    ServletContext config = getServletContext();
    _contextHandler = ((ContextHandler.Context) config).getContextHandler();
    Handler handler = _contextHandler.getHandler();
    while (handler != null && !(handler instanceof ServletHandler) && (handler instanceof HandlerWrapper)) handler = ((HandlerWrapper) handler).getHandler();
    _servletHandler = (ServletHandler) handler;
    Enumeration<String> e = getInitParameterNames();
    while (e.hasMoreElements()) {
        String param = e.nextElement();
        String value = getInitParameter(param);
        String lvalue = value.toLowerCase(Locale.ENGLISH);
        if ("nonContextServlets".equals(param)) {
            _nonContextServlets = value.length() > 0 && lvalue.startsWith("t");
        }
        if ("verbose".equals(param)) {
            _verbose = value.length() > 0 && lvalue.startsWith("t");
        } else {
            if (_parameters == null)
                _parameters = new HashMap<String, String>();
            _parameters.put(param, value);
        }
    }
}

Example 2 with ServletContext

use of javax.servlet.ServletContext in project jetty.project by eclipse.

public void init() throws ServletException {
    ServletContext context = getServletContext();
    ContextHandler.Context scontext = (ContextHandler.Context) context;
    Server _server = scontext.getContextHandler().getServer();
    Handler handler = _server.getChildHandlerByClass(StatisticsHandler.class);
    if (handler != null) {
        _statsHandler = (StatisticsHandler) handler;
    } else {
        LOG.warn("Statistics Handler not installed!");
        return;
    }
    _memoryBean = ManagementFactory.getMemoryMXBean();
    _connectors = _server.getConnectors();
    if (getInitParameter("restrictToLocalhost") != null) {
        _restrictToLocalhost = "true".equals(getInitParameter("restrictToLocalhost"));
    }
}

Example 3 with ServletContext

use of javax.servlet.ServletContext in project jetty.project by eclipse.

the class QoSFilter method init.

public void init(FilterConfig filterConfig) {
    int max_priority = __DEFAULT_MAX_PRIORITY;
    if (filterConfig.getInitParameter(MAX_PRIORITY_INIT_PARAM) != null)
        max_priority = Integer.parseInt(filterConfig.getInitParameter(MAX_PRIORITY_INIT_PARAM));
    _queues = new Queue[max_priority + 1];
    _listeners = new AsyncListener[_queues.length];
    for (int p = 0; p < _queues.length; ++p) {
        _queues[p] = new ConcurrentLinkedQueue<>();
        _listeners[p] = new QoSAsyncListener(p);
    }
    int maxRequests = __DEFAULT_PASSES;
    if (filterConfig.getInitParameter(MAX_REQUESTS_INIT_PARAM) != null)
        maxRequests = Integer.parseInt(filterConfig.getInitParameter(MAX_REQUESTS_INIT_PARAM));
    _passes = new Semaphore(maxRequests, true);
    _maxRequests = maxRequests;
    long wait = __DEFAULT_WAIT_MS;
    if (filterConfig.getInitParameter(MAX_WAIT_INIT_PARAM) != null)
        wait = Integer.parseInt(filterConfig.getInitParameter(MAX_WAIT_INIT_PARAM));
    _waitMs = wait;
    long suspend = __DEFAULT_TIMEOUT_MS;
    if (filterConfig.getInitParameter(SUSPEND_INIT_PARAM) != null)
        suspend = Integer.parseInt(filterConfig.getInitParameter(SUSPEND_INIT_PARAM));
    _suspendMs = suspend;
    ServletContext context = filterConfig.getServletContext();
    if (context != null && Boolean.parseBoolean(filterConfig.getInitParameter(MANAGED_ATTR_INIT_PARAM)))
        context.setAttribute(filterConfig.getFilterName(), this);
}

Example 4 with ServletContext

use of javax.servlet.ServletContext in project jetty.project by eclipse.

the class WebAppContextTest method testRealPathDoesNotExist.

@Test
public void testRealPathDoesNotExist() throws Exception {
    Server server = new Server(0);
    WebAppContext context = new WebAppContext(".", "/");
    server.setHandler(context);
    server.start();
    ServletContext ctx = context.getServletContext();
    assertNotNull(ctx.getRealPath("/doesnotexist"));
    assertNotNull(ctx.getRealPath("/doesnotexist/"));
}

Example 5 with ServletContext

use of javax.servlet.ServletContext in project jetty.project by eclipse.

    configuration.getFactory().getPolicy().setMaxTextMessageSize(10 * 1024 * 1024);
    configuration.addMapping("/info/*", this);
