You cannot. A JSP Page contains a lot more contents than just HTML. It contains JavaScript, Java Scriptlets etc. So a HTML cannot be directly converted to a JSP unless someone sits and adds the other contents to the JSP that makes it a JSP
Yes a user defined exception can have any number of methods in it. A user defined exception is nothing but a Java class created for a specific purpose. Just like ordinary Java classes, you can have any number of methods in it...
Fields and methods. Fields are variables defined at the class level, i.e., they are available for all methods. Methods are the equivalent of functions / procedures, but they are defined for a specific class.
A blown engine.
We can do validation by using JavaScript. Here we are using function Validate(). Iam creating one JSP name index.jsp & give a link to another JSP name basic.jsp. In that Jsp iam using Type 1 Jdbc Driver & giving a database connection
The 3 life cycle methods in a JSP page are:jspInit() - Called when the JSP page is initializedjspService() - Called everytime a request/response is received/submittedjspDestroy() - Called when the JSP is no longer required
A JSP gets converted into a Servlet for execution and hence the methods in a JSP are similar to the ones in a Servlet.Scriptlets and Expressions will end up in the body of doGet or doPostDeclarations will end up as instance variablesjspInit() and jspDestroy() will get translated to Servlet's init() and destroy() methods
JSP actions are XML tags that direct the server to use existing components or control the behavior of the JSP engine. JSP Actions consist of a typical (XML-based) prefix of "jsp" followed by a colon, followed by the action name followed by one or more attribute parameters. There are six JSP Actions: < jsp : include / > < jsp : forward / > < jsp : plugin / > < jsp : usebean / > < jsp : setProperty / > < jsp : getProperty / >
In JSP, the extends attribute is used in the <jsp:directive.page> tag to specify a superclass for the JSP page. This allows the JSP to inherit methods and properties from the specified Java class, enabling code reuse and organization. By extending a class, you can implement custom functionality or override methods, enhancing the capabilities of your JSP. For example, you might use extends to create a base page class that handles common logic for multiple JSP files.
JSP file would be automatically compiled by an engine called Jasper in the servelt containter.
You cannot override the jspService() method but you can override the jspInit() and jspDestroy() methods
You can use the errorPage attribute of the page directive. If this attribute is defined in a JSP page, when a run time exception is encountered, the control will be transferred to this JSP page. This error page can access details of the Exception from the request and use it to display a logical message to the user.
JavaServer Pages (JSP) are translated into servlets by the JSP engine during the compilation process. When a JSP file is requested for the first time, the server converts it into a servlet class, which involves converting JSP tags and expressions into Java code that adheres to the servlet API. This generated servlet is then compiled into bytecode and executed, allowing dynamic web content to be served. Subsequent requests utilize the compiled servlet, improving performance.
JSP stands for the java server pages and it can be used independently or as the view component of a server-side model.JSP allows Java code and certain pre-defined actions to be interleaved with static web markup page.
The tag lib directive is used in JSPs to include tag libraries. < % @ taglib uri=http://www.myCompany.com/myTagLibrary prefix="myLibrary" % > This is how you include a tag library into a JSP
JSP stands for Java Server Pages
can i get update coding in jsp??
