Description

Syntax

JSP

XML

Tag

TS, TX

Similar to the page directive in a

<%@ tag

<jsp:directive.tag tagDirectiveAttrList />

JSP page, but applies to tag files

[ display-name="name of the tag file | display-name" ]

instead of JSP pages. As with the

[ body-content="scriptless|tagdependent|empty" ]

where tagDirectiveAttrList is the same as the list in the JSP

page directive, a translation unit

[ dynamic-attributes="page-scoped attribute" ]

column.

can contain more than one

[ small-icon="relativeURL" ]

instance of the tag directive. All

[ large-icon="relativeURL" ]

the attributes apply to the

[ description="text" ]

complete translation unit.

[ example="text" ]

However, there can be only one

[ language="java" ]

occurrence of any attribute or

[ import="{package.class | package.*} , ... " ]

value defined by this directive in

[ pageEncoding="{characterSet | ISO-8859-1}" ]

a given translation unit. With the

[ isELIgnored="true|false" ]

exception of the import attribute,

multiple attribute or value

(re)definitions result in a

translation error.

Also used for declaring custom

tag properties such as display

name.

Taglib

S, TS

Defines a tag library and prefix

<%@ taglib {uri="URI"

No equivalent. Included in <jsp:root> and in any other XML

for custom tags used in the JSP

| tagdir="/WEB-INF/tags[/subdir]+" } prefix="tagPrefix"

element using the xmlns attribute instead:

page.

<anyxmlelement xmlns:prefix="{uri | urn:jsptld:path |

urn:jsptagdir:/WEB-INF/tags[/subdir]+ }"

Examples:

<my:tag xmlns:my=" />

<my:tag xmlns:my="urn:jsptld:/WEB-INF/tlds/my.tld" />

<my:tag xmlns:my="urn:jsptagdir:/WEB-INF/tags" />

Variable

TS, TX

Declares an expression language

<%@ variable

<jsp:directive.variable variableDirectiveAttrList />

{ name-given="scripting variable"

variable exposed by the tag to

the calling page.

| (name-from-attribute="scripting variable"

where variableDirectiveAttrList is the same as the list in the

alias="locally-scoped attribute") }

JSP column.

[ variable-class="java.lang.String | name of the variable class"

]

[ declare="true | false" ]

[ scope="AT_BEGIN | AT_END | NESTED" ]

[ description="text" ]
