John Muir, a gifted inventor, scientist and noted naturalist with a passion for preserving America's remaining wild lands, cofounded the Sierra Club with 27 members in 1892. Today, with a membership of 700,000, the mission and passion survive undiminished. Sierra Club's Take Action Web site makes it easy for visitors to respond to current environmental alerts by sending fully composed e-mails, faxes or letters to empowered government officials.

For the Sierra Club, Sybase EAServer provided a clear evolutionary path from existing PowerBuilder-based applications to full Web-enabled applications. I was able to adapt portions of existing PowerBuilder logic to new EAServer nonvisual object components. Java servlets field incoming visitor requests and pass the information to the PowerBuilder components, which then make requests to the Adaptive Server Enterprise database. Servlets take the returned data structures and complete the Java server pages (JSPs). I also used Java servlets to look up visitor ZIP codes. A servlet submits a firm to an address verification vendor, and the corrected information is returned to the servlet which reformats the information and stores it in the visitor's record, ensuring any correspondence with the government will contain the correct address. PowerJ was used to develop all the Take Action servlets.
