What do you understand by jsp actions

By using the jsp:useBean action, you create a new object with the object name objectName of the class package. Later on, you can access the properties of this object by using either jsp:setProperty or jsp:getProperty. First, we have a JavaBeans call Message:. We use jsp:setProperty to set the text property of the JavaBean Message and then we call jsp:getProperty to get that message and print it out. Here is the output screenshot:.

The jsp:useBean tag is utilized to start up an object of JavaBean or it can re-utilize the existing java bean object.

The primary motivation behind jsp:useBean tag is to interface with bean objects from a specific JSP page. In this tag, it is consistently suggestible to give either application or meeting degree to the extension characteristic worth.

At the point when the compartment experiences this label then the holder will get class characteristic worth for example completely qualified name of Bean class then the holder will perceive Bean. Subsequent to making the Bean object compartment will allot Bean object reference to the variable indicated as an incentive to id property.

In the wake of getting Bean object reference holder will store Bean object in an extension indicated as an incentive to scope trait. In this example, we have created a simple Bean class Calculator. The jsp:attribute tag is utilized to characterize the XML content powerfully. In jsp:attribute label the components can be created during demand time than assemblage time.

This tag really characterizes the trait of XML which will be produced progressively. The jsp:body tag is utilized to characterize the XML progressively. In jsp:body label the components can produce during demand time than accumulation time.

This tag really characterizes the XML, which is produced progressively component body. In this example, we are taking text object to print the template text. To perform activities in the event that we use scripting components, at that point we need to give Java code inside the JSP pages.

On the off chance that we need to take out scripting components from JSP pages, we need to utilize activities. Custom activities are JSP activities that could be set up by the designers according to their application prerequisites. In JSP innovation, standard activities will be spoken to as a bunch of predefined labels are called Action Tags.

In JSP Technology, standard activities will be spoken to as a bunch of predefined labels are called Action labels. Additionally, all the custom activities will be spoken to as a bunch of clients characterized labels are called Custom Tags. If we want to design custom tags in our JSP applications then we have to use the following 3 elements:.
