JSP tutorial part 15:Invoking a JSP Page from a Servlet

Invoking a JSP Page from a Servlet

You can invoke a JSP page from a servlet through functionality of the

standard javax.servlet.RequestDispatcher interface.

Complete the following steps in your code to use this mechanism:

· Get a servlet context instance from the servlet instance:

ServletContext sc = this.getServletContext();

· Get a request dispatcher from the servlet context instance, specifying the absolute

path of the target JSP page as input to the getRequestDispatcher() method:

RequestDispatcher rd = sc.getRequestDispatcher("/jsp/mypage.jsp");

· Invoke the include() or forward() methods of the request dispatcher, specifying the

HTTP request and response objects as arguments.

rd.include(request, response); or

rd.forward(request, response);

· The functionality of these methods is similar to that

of jsp:include and jsp:forward actions.

Note : To implement MVC Architecture, we use the above technique

Applications of Insulating Materials

All electrical systems require some kind of insulation to prevent short circuits and leaking currents. 3 forms of insulators: solid, liquid and gaseous Performance of these insulators depend on the temperature Classification according to their temperature rating. Impregnation: Letting the solid material absorb some liquid With the advent of new materials, the classification has been modified by International Electrotechnical Commission: The transformer insulation: (a) conductor or turn-to-turn insulation, (b) coil-to-coil insulation, (c) low voltage coil-to-earth insulation, (d) high voltage coil-to-low voltage coil insulation, and (e) high voltage coil-to-ground insulation. Transformer oil -- provides the required dielectric strength and insulation -- cools the transformer by circulating itself through the core and the coil structure. -- should be in the liquid state over the complete operating range of temperatures between -40°C and+50°C. -- gets o...

PV/GENSET HYBRID

Introduction: PV and genset systems do not have much in common. It is precisely for this reason that they can be mated to form a hybrid system that goes far in overcoming the drawbacks to each technology. Table 10.1 lists the respective advantages and disadvantages. As the sun is a variable energy source, PV system designs are increased in size (and therefore cost) to allow for a degree of system autonomy. Autonomy is required to allow for provision of reliable power during "worst case" situations, which are usually periods of adverse weather, seasonally low solar insulation values or an unpredicted increased demand for power. The addition of autonomy to the system is accomplished by increasing the size of the PV array and its requisite energy storage system (the battery). When a genset is added, additional battery charging and direct AC load supply capabilities are provided. The need to build in system autonomy is therefore greatly reduced. When energy demands cannot b...
