Example filter that sets the character encoding to be used in parsing the + * incoming request, either unconditionally or only if the client did not + * specify a character encoding. Configuration of this filter is based on + * the following initialization parameters:

+ *

encoding - The character encoding to be configured + * for this request, either conditionally or unconditionally based on + * the ignore initialization parameter. This parameter + * is required, so there is no default.
ignore - If set to "true", any character encoding + * specified by the client is ignored, and the value returned by the + * selectEncoding() method is set. If set to "false, + * selectEncoding() is called only if the + * client has not already specified an encoding. By default, this + * parameter is set to "true".

+ * + *

Although this filter can be used unchanged, it is also easy to + * subclass it and make the selectEncoding() method more + * intelligent about what encoding to choose, based on characteristics of + * the incoming request (such as the values of the Accept-Language + * and User-Agent headers, or a value stashed in the current + * user's session.

This tag handler accepts a "num" parameter and repeats the body of the + tag "num" times. It's a simple example, but the implementation of + such a tag in JSP 2.0 is substantially simpler than the equivalent + JSP 1.2-style classic tag handler.
+
The body of the tag is encapsulated in a "JSP Fragment" and passed + to the tag handler, which then executes it five times, inside a + for loop. The tag handler passes in the current invocation in a + scoped variable called count, which can be accessed using the EL.

Tag Plugins: Introductory Notes
+
+ Tomcat 5 provides a framework for implementing tag plugins. The + plugins instruct Jasper, at translation time, to replace tag handler + calls with Java scriptlets. + The framework allows tag library authors to implement plugins for + their tags. +
+
+ Tomcat 5 is released with plugins for several JSTL tags. Note + that these plugins work with JSTL 1.1 as well as JSTL 1.0, though + the examples uses JSTL 1.1 and JSP 2.0. + These plugins are not complete (for instance, some item types not + handled in <c:if>). + They do serve as examples to show plugins in action (just + examine the generated Java files), and how they can be implemented. +
