File Extension .Jsp

JSP stands for “Java Server Page” and thus files with this file extension are web pages that contain executable Java code. JSP files could also be under different file extensions like JHTML and/or JHTM. The contents of JSP files are human-readable (in contrast with machine-readable) and so JSP files can therefore be opened and modified with any text editor aside from the appropriate web development programs like Dreamweaver and HomeSite. JSP files are parsed and executed by a web server application like Microsoft Inc.’s IIS or Internet Information Server and as well as Apache to generate its content which is then presented to the user through a web browser like Mozilla Firefox and Internet Explorer.

JSP files are highly similar to PHP, ASP and Perl files in that they only run on a web server and that the user of the files do not see the actual code but only the results of the code on a web browser. For an instance, a JSP file could contain a query to a database to generate a tabular result of data and display it for the user to see. The result could be nicely formatted with XHTML and CSS but the user didn’t really know that or even have the idea about what is happening in the JSP file just to display the results.

However, since JSP files contain macros and executable codes, users since treat these files with caution. Though these files can be opened and modified using a text-editor, users are advised not to do so. There are a lot of security holes and vulnerability issues in Java programming that can be exploited by malicious minds and so extreme precautions is highly recommended in dealing with JSP files. Below are the programs that can open JSP files:
