History[edit]

The Servlet specification was created by Sun Microsystems, with version 1.0 finalized in June 1997. Starting with version 2.3, the specification was developed under the Java Community Process. JSR 53 defined both the Servlet 2.3 and JavaServer Page 1.2 specifications. JSR 154 specifies the Servlet 2.4 and 2.5 specifications. As of March 26, 2010, the current version of the Servlet specification is 3.0.

In his blog on java.net, Sun veteran and GlassFish lead Jim Driscoll details the history of servlet technology.^[4] James Gosling first thought of servlets in the early days of Java, but the concept did not become a product until Sun shipped the Java Web Server^[clarify] product. This was before what is now the Java Platform, Enterprise Edition was made into a specification.
