You want to download the Java Web Services Developer Pack (WSDP) so that you can use a JSTL 1.1 reference implementation.
Visit the Sun Microsystems Java WSDP download site at http://java.sun.com/ webservices /jwsdp.
The Java WSDP Version 1.2 contains reference implementations of the JSTL 1.1, as well as several other web tier technologies, including the Servlet API 2.4 and JSP 2.0. The WSDP is bundled with Tomcat 5, so once you install the WSDP you can experiment with the various technologies, including JavaServer Faces, Java Architecture for XML Binding (JAXB), Java API for XML Processing, and Java API for XML-based RPC (Jax-RPC).
The Java WSDP 1.2 installs on both Windows and various Unix systems, such as Solaris and Linux. Recipe 23.15 shows how to use JSTL 1.1 functions; I use the WSDP for this recipe.
