| <h1 class="topictitle1">JavaServer Pages (JSP) technology</h1> |
| <div><p>The JavaServer Pages technology enables you to generate dynamic web content, |
| |
| such as HTML, DHTML, XHTML, and XML files, to include in a Web application. |
| |
| JSP files are one way to implement server-side dynamic |
| |
| page content. JSP files allow a Web server, such as WebSphere<sup>®</sup> Application |
| |
| Server or Apache Tomcat, to add content dynamically to your HTML pages before |
| |
| they are sent to a requesting browser.</p> |
| <p>When you deploy a JSP file to a Web server that provides a servlet engine, |
| |
| it is preprocessed into a servlet that runs on the Web server. This is in |
| |
| contrast with client-side JavaScript (within <samp class="codeph"><SCRIPT></samp> tags), |
| |
| which is run in a browser. A JSP page is ideal for tasks that are better suited |
| |
| to execution on the server, such as accessing databases or calling Enterprise Java beans.</p> |
| <p>You can create and edit a JSP file in the HTML editor |
| |
| by adding your own text and images using HTML, JSP tagging, or JavaScript, |
| |
| including Java source code inside of scriptlet tags. Typically, |
| |
| JSP files have the file extension .jsp. Additionally, the JSP specification |
| |
| suggests that JSP fragment files should have file extension .jspf. If this |
| |
| convention is not followed, the JSP validator will treat JSP fragments as |
| |
| regular standalone JSP files, and compilation errors might be reported.</p> |
| <p>The <cite>Sun Microsystems JSP 1.2 Specification</cite> provides the ability |
| |
| to create custom JSP tags. Custom tags simplify complex actions and |
| |
| provide developers with greater control over page content. Custom tags are |
| |
| collected into a library (taglib). A tag library descriptor file (taglib.tld) |
| |
| is an XML document that provides information about the tag library, including |
| |
| the taglib short name, library description, and tag descriptions. Refer to |
| |
| the <cite>Sun Microsystems JSP 1.2 Specification</cite> for more details.</p> |
| <p>To use JSP 1.2 custom taglibs, you can import the tag library .tld and |
| |
| .jar files into your project to use them, or associate them as Web Library |
| |
| projects. You can also reference a TLD file by using a URI.</p> |
