Use a jsp:expression to write the date and time in the browser's locale:
</div>
<jsp:expression>getDateTimeStr(request.getLocale())</jsp:expression>
</div>
<jsp:text> <p>This sentence is enclosed in a jsp:text element.</p> </jsp:text>
</body> </html> </jsp:root>

What is good with Web services is that they are simple enough to get momentum. There is nothing new under the sun with them technically speaking. CORBA is more efficient as is COM+. But, they are not easy enough to use for everyone. Webservices appears to be simple. So they win. This sounds like "20% of UML is sufficient for modeling".
