dsp:importbean can import a servlet bean or a JavaBean component into a JSP. After a component is imported, references to it can omit its full Nucleus path. You can also use dsp:importbean to map the imported component to a scoped attribute that is EL-accessible. dsp:importbean tags are typically placed at the top of the JSP, in order to facilitate references to them.
Attributes
ImportedComponent:bean(Required)
The bean attribute accepts the fully-qualified Nucleus path and name for the servlet bean you want to import.
ServletBeanasanAttribute:var
The var attribute names an EL variable that makes the servlet bean instance accessible to other tags on the page. When var is omitted, the shorthand name for the component is used.
VariableScope:scope
The scope attribute determines where the servlet bean variable identified by the var attribute is stored and what resources can access it. Options include: page, request, session, or application. Omitting this attribute causes the default, page, to be used.
Example
<dsp:importbean bean="/atg/dynamo/droplet/Switch"/>
<dsp:importbean bean="/atg/dynamo/servlet/RequestLocale"
var="requestlocale"/>
<dsp:importbean bean="/atg/dynamo/droplet/Redirect/>
<dsp:setvalue bean="${requestLocale.refresh}" value=" "/>
<dsp:droplet name="Switch">
<dsp:param bean="${requestLocale.locale.language}" name="value"/>
<dsp:oparam name="fr">
<dsp:droplet name="Redirect">
<dsp:param name="url" value="fr/index.jsp"/>
</dsp:droplet>
</dsp:oparam>
<dsp:oparam name="de">
<dsp:droplet name="Redirect">
<dsp:param name="url" value="de/index.jsp"/>
</dsp:droplet>
</dsp:oparam>
<dsp:oparam name="default">
<dsp:droplet name="Redirect">
<dsp:param name="url" value="en/index.jsp"/>
</dsp:droplet>
</dsp:oparam>
</dsp:droplet>In this example, Switch, RequestLocale, and Redirect are imported to the current JSP. When these components are used elsewhere in the page, they use the component and property names only. The RequestLocale component is imported to a var attribute so the dsp:setvalue and dsp:param tags can access RequestLocale with EL.
This code sample uses tags from the DSP and JSTL Core tag library.
