This tag library provides Tiles tags.
]]>
insertTemplate
org.apache.tiles.jsp.taglib.InsertTemplateTag
JSP
Insert a template.
Insert a template with the possibility to pass
parameters (called attributes).
A template can be seen as a procedure that can take parameters or attributes.
<tiles:insertTemplate> allows to define these attributes
and pass them to the inserted jsp page, called template.
Attributes are defined using nested tag
<tiles:putAttribute> or
<tiles:putListAttribute>.
You must specify template attribute, for inserting a template
Example :
<tiles:insertTemplate template="/basic/myLayout.jsp" flush="true">
<tiles:putAttribute name="title" value="My first page" />
<tiles:putAttribute name="header" value="/common/header.jsp" />
<tiles:putAttribute name="footer" value="/common/footer.jsp" />
<tiles:putAttribute name="menu" value="/basic/menu.jsp" />
<tiles:putAttribute name="body" value="/basic/helloBody.jsp" />
</tiles:insertTemplate>
]]>
template
true
true
A string representing the URI of a template (for example, a JSP
page).
]]>
flush
false
false
boolean
True or false. If true, current page out stream is flushed
before insertion.
]]>
ignore
false
true
boolean
If this attribute is set to true, and the attribute specified by the
name does not exist, simply return without writing anything. The
default value is false, which will cause a runtime exception to be
thrown.
]]>
role
false
true
If the user is in the specified role, the tag is taken into account;
otherwise, the tag is ignored (skipped).
]]>
preparer
false
true

insertDefinition
org.apache.tiles.jsp.taglib.InsertDefinitionTag
JSP
Insert a definition.
Insert a definition with the possibility to override and specify
parameters (called attributes).
A definition can be seen as a (partially or totally) filled template that
can override or complete attribute values.
<tiles:insertDefinition> allows to define these attributes
and pass them to the inserted jsp page, called template.
Attributes are defined using nested tag <tiles:putAttribute> or
<tiles:putListAttribute>.
You must specify name tag attribute, for inserting a definition from
definitions factory.
Example :
<tiles:insertDefinition name=".my.tiles.defininition flush="true">
<tiles:putAttribute name="title" value="My first page" />
<tiles:putAttribute name="header" value="/common/header.jsp" />
<tiles:putAttribute name="footer" value="/common/footer.jsp" />
<tiles:putAttribute name="menu" value="/basic/menu.jsp" />
<tiles:putAttribute name="body" value="/basic/helloBody.jsp" />
</tiles:insertDefinition>
]]>

insertAttribute
org.apache.tiles.jsp.taglib.InsertAttributeTag
JSP
Inserts the value of an attribute into the page.
This tag can be flexibly used to insert the value of an attribute into a page.
As in other usages in Tiles, every attribute can be determined to have a "type",
either set explicitly when it was defined, or "computed". If the type is not explicit, then
if the attribute value is a valid definition, it will be inserted as such. Otherwise,
if it begins with a "/" character, it will be treated as a "template". Finally, if it
has not otherwise been assigned a type, it will be treated as a String and included without
any special handling.
Example :
<tiles:insertAttribute name="body" />
]]>
name
false
true

the value attribute is specified.

Exception is thrown if no appropriate tag can be found.
Put tag can have following atributes :
- name : Name of the attribute
