Both JSP and PHP are two popular technologies that serve to create dynamic web pages. Both are similar in the ways that they allow developers to embed code within an HTML document that can interact with databases, sessions, cookies, and other web features. However, they also have some significant differences that may affect the choice of which one to use for a web project. In this article, we will try to find the difference between JSP and PHP in terms of their syntax, performance, scalability, security, and compatibility. JSP vs PHP JSP It is an acronym that stands for Java ... Read More

JSP and ASP are both server-side scripting languages. JSP is Java based and is developed by Sun Microsystems, whereas ASP is developed by Microsoft and is also referred as Classic ASP. Whenever a browser requests a JSP or ASP page, the server engine reads the file, executes the code in file and returns the HTML output to the browser.JSP is compiled, whereas ASP is interpreted. ASP.NET is a .NET based variant of ASP where the codes are compiled to improve the performance.What is ASP?ASP is a server-side scripting engine, which means the code that is written gets sent to the ...

Both Servlets and JSP are used in web development. The Servlets handle the logic (processing our requests and interacting with databases), and JSPs handle the presentation (displaying dynamic content on the web page). By separating the logic and presentation, our web applications become more manageable and scalable. In brief, we can think of Servlets as Java programs that run on a web server. They work as the middle layer between a request from an HTTP client (like a browser) and databases or applications on the server. When we send a request to a server, the Servlet processes that request, and ... Read More

The fn:indexOf() function returns the index within a string of a specified substring.SyntaxThe fn:indexOf() function has the following syntax −int indexOf(java.lang.String, java.lang.String)ExampleFollowing is the example to explain the functionality of the fn:indexOf() function − Using JSTL Functions Index (1) : ${fn:indexOf(string1, "first")} Index (2) : ${fn:indexOf(string2, "second")} You will receive the following result −Index (1) : 8 Index (2) : 13

The fn:escapeXml() function escapes characters that can be interpreted as XML markup.SyntaxThe fn:escapeXml() function has the following syntax −java.lang.String escapeXml(java.lang.String)ExampleFollowing is the example to explain the functionality of the fn:escapeXml() function − Using JSTL Functions With escapeXml() Function: string (1) : ${fn:escapeXml(string1)} string (2) : ${fn:escapeXml(string2)} Without escapeXml() Function: string (1) : ${string1} string (2) : ${string2} You will receive the following result −With escapeXml() Function: string (1) : This is first String. string (2) : This is second String. Without escapeXml() Function − string (1) : This is first String. string (2) : This is second String.

The fn:endsWith() function determines if an input string ends with a specified suffix.SyntaxThe fn:endsWith() function has the following syntax −boolean endsWith(java.lang.String, java.lang.String)ExampleFollowing example explains the functionality of the fn:substring function −           Using JSTL Functions                              String ends with 123                      String ends with TEST       You will receive the following result −String ends with 123

The fn:containsIgnoreCase() function determines whether an input string contains a specified substring. While doing search it ignores the case.SyntaxThe fn:containsIgnoreCase() function has the following syntax −boolean containsIgnoreCase(java.lang.String, java.lang.String)ExampleFollowing is the example to explain the functionality of the fn:containsIgnoreCase() function −           Using JSTL Functions                              Found test string                      Found TEST string         You will receive the following result −Found test string Found TEST string

The fn:contains() function determines whether an input string contains a specified substring.SyntaxThe fn:contains() function has the following syntax −boolean contains(java.lang.String, java.lang.String)ExampleFollowing example explains the functionality of fn:contains() function −           Using JSTL Functions     Found test string Found TEST string You will receive the following result −Found test string

The tag works like a Java switch statement. With this, you can choose between a number of alternatives. Where the switch statement has the case statements, the tag has the tags. In a similar way, a switch statement has the default clause to specify a default action and the tag has the tag as the default clause.AttributeThe tag does not have any attribute.The tag has one attributes which is listed below.The tag does not have any attribute.The tag has the following attributes −AttributeDescriptionRequiredDefaultselectCondition to evaluateYesNoneExample         ...
