JET Syntax Reference

JET has the following directives

@jet - affects Java code created by the JET compiler.
@taglib - imports a tag library into the template for use, and assigns it a unique namespace prefix.

JET recognizes the following "Classic" JET directives, but does not yet implement them. An error message is issued if any of the following directives are recognized:

@include
@start
@end

To emit the characters <%@ in a templates output, enter <\%@. To emit %>, enter %\>

The @jet directive

The @jet directive controls the name of the generated Java class, its containing package and the Java classes it imports.

All attributes are optional.The following tag summarizes the available attributes.

Attribute	Usage
package	Name of package into which the template will be compiled. May be used only once per template.
class	Name of Java class to be generated. May be used only once per template.
imports	A space separated list of Java import locations.
startTag	A two character replacement for <% in subsequent JET elements.
endTag	A two character replacement for %> in subsequent JET elements.

The @taglib directive

The @taglib directive imports an XML tag library, or renames the taglibrary namespace prefix. Example:

<%@taglib id="org.eclipse.jet.controlTags" prefix="cc"%>

The value for prefix must be value XML NCName, namely, it must start with letter or underscore (_), and then contain letters, digits or the characters underscore (_), hyphen (-) or dot (.).

The id for the Standard JET tag libaries are:

Tag Library	ID
