      addELContextListener in interface JspApplicationContext
      Parameters:
      listener - The listener to add

    • getInstance

      public static JspApplicationContextImpl getInstance(jakarta.servlet.ServletContext context)

    • createELContext

      public ELContextImpl createELContext(JspContext context)

    • fireListeners

      protected void fireListeners(ELContext elContext)

    • addELResolver
