Class TLcdWMSServlet

java.lang.Object
jakarta.servlet.GenericServlet
jakarta.servlet.http.HttpServlet
com.luciad.wms.server.TLcdWMSServlet
All Implemented Interfaces:
jakarta.servlet.Servlet, jakarta.servlet.ServletConfig, Serializable
public class TLcdWMSServlet extends jakarta.servlet.http.HttpServlet
This class represents a servlet implementation with support for the OGC Web Map Service (WMS) 1.1.1 / 1.3.0 standard, including the WMS SLD profile. The initialization of this servlet (creation of a handler for all requests / responses, data loading, rendering configuration, ...) is managed by the factory class ALcdOGCWMSCommandDispatcherFactory, which is created through the method createCommandDispatcherFactory(ServletConfig). By default, it creates an instance through reflection, based on the class name specified by the servlet configuration parameter command.dispatcher.factory.class.

All request and response handling is delegated to a single ALcdWMSCommandDispatcher instance, which is created through ALcdOGCWMSCommandDispatcherFactory.createOGCWMSCommandDispatcherInstance(ServletConfig).

    • createCommandDispatcherFactory

      protected ALcdWMSCommandDispatcherFactory createCommandDispatcherFactory(jakarta.servlet.ServletConfig aServletConfig) throws jakarta.servlet.ServletException
      Creates a command dispatcher factory for the given servlet configuration. The command dispatcher factory configures the operational behavior of this servlet, such as the data to be offered and their styling. It is also responsible for creating a command dipatcher, which is used during the lifetime of this servlet to handle incoming requests.

      The command dispatcher factory class ALcdWMSCommandDispatcherFactory focuses on supporting the OGC WMS 1.1.1 / 1.3.0 standard, which defines the GetCapabilities, GetMap and GetFeatureInfo requests. To support the WMS SLD profile, an instance of ALcdOGCWMSCommandDispatcherFactory should be returned that registers support for the additional methods DescribeLayer, GetLegendGraphic and SLD-enabled GetMap requests.

      By default, the implementation looks for the servlet parameter "command.dispatcher.factory.class" and creates a command dispatcher factory via reflection.
      Parameters:
      aServletConfig - a configuration to initialize this servlet with
      Returns:
      a command dispatcher factory for the given servlet configuration
      Throws:
      jakarta.servlet.ServletException - if the instantiation of the command dispatcher factory fails
