About 4GL Web pages
4GL Web pages are
enhanced Web pages that incorporate extensions to the Web Target
object model to generate template (source) code for dynamic Web
pages. 4GL Web pages rely on the object model to handle the complexities
of data transfer, HTML generation, and Java or JavaScript generation
for server scripts. With many of the implementation details taken
care of for you, you can concentrate on designing your pages and
coding the application logic.
4GL Web pages integrate with other Web pages on your Web site.
They are suitable for sharing data with other pages across your
site and accessing components installed on EAServer. 4GL Web pages
provide enhanced support for Web DataWindow objects on HTML or JSP
pages. You cannot hand code a Web DataWindow on a 4GL Web page.
4GL HTML pages can be deployed to the PowerDynamo application
server, which processes the server scripts to deliver dynamic content
to your users. 4GL JSP pages can also be deployed to Tomcat, EAServer,
or other JSP 1.2 servers that support command line deployment.
4GL Web pages help you:
- Manage page data among Web pages (using
page parameters, page variables, and session variables) - Access data from EAServer components
- Bind data to controls on your page
- Manage page navigation
- Create server scripts with minimal coding effort
- Debug page processing
