Integrating XSL-FO into Web-Based Applications

Tue, 31 Aug 2004 00:00:00 EDT

This article demonstrates how we can integrate XSL-FO, XSLT, and JavaMail into our existing web-based applications. I show you how we can generate PDF reports for an application through the use of XSLT and XSL-FO embedded within the Java application. I also illustrate how the generated PDF file can be sent as an e-mail attachment using JavaMail.

Exposing Legacy Applications

SOAP (Simple Object Access Protocol) is a wire protocol that is similar to CORBA's Internet Inter-ORB protocol (IIOP) for communicating between applications running on different operating systems, with different technologies and programming languages. Unlike IIOP, which is binary in nature, SOAP is text based. This XML-based protocol lets you call an application, or even an individual object or method within an application, across the Internet via HTTP. HTTP does not pose any compatibility and security problems, unlike RPC, since all Internet browsers and servers support HTTP.
