--&gt; if i define an attribute in my tag file as required=true, what happens if someone uses my tag and completely leaves out that attribute?<br />
required=true means the attribute must be defined (you can not leave it out)<br />
<br />
For dependent attribute or attribute validation, you may use TEI tag extending the TagExtraInfo class. Have a look at the following link for &quot;Attribute Validation&quot;<br />

im creating a single tag file (not a tag library)<br />
<br />
if i define an attribute in my tag file as required=true, what happens if someone uses my tag and completely leaves out that attribute?<br />
<br />
also how can i make it so that if one attribute is specified as &quot;false&quot; when someone uses my tag it then requires another attribute to be defined but if its true then the attribute is not required.

jsp tag file question

Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services using a wide variety of languages and standards, including the familiar HTML, JavaScript and jQuery, ASP and ASP.NET, PHP, ColdFusion, CSS, PHP, Flex and Flash, but also the implementation of a broad list of standards including XML, WSDL, SSDL, VoiceXML and many more.

Web Languages and Standards

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
