Use JSTL tags for ATG droplets and beans

Question

Hi,
I am trying to display profile values in a JSON object in jsp.
<dsp:getvalueof var="json" bean="ProfileFormHandler.ProfileJSON"></dsp:getvalueof>
<c:out value="${json}" />
but instead of using dsp tag is there a way for accessing ProfileFormHandler using JSTL tag
Also how can we use droplets in ATG like ForEach using JSTL tags only
<dsp:droplet name="ForEach">
<dsp:param name="array" param="catalogItems.rootCategories"/>
<dsp:param name="elementName" value="categoryItem"/>

I am trying to display profile values in a JSON object in jsp.
<dsp:getvalueof var="json" bean="ProfileFormHandler.ProfileJSON"></dsp:getvalueof>
<c:out value="${json}" />
but instead of using dsp tag is there a way for accessing ProfileFormHandler using JSTL tagIn the <dsp:importbean> use var to give an EL variable name to the component you are importing.You can also set its scope attribute to page, request, session, or application with page scope being the default. You can then access it as a page scoped attribute. So this should do:
<dsp:importbean var="profileFormHandler" bean="/atg/userprofiling/ProfileFormHandler" />
<c:out value="${pageScope.profileFormHandler.ProfileJSON}" />In case you change the scope in importbean you can accordingly use pageScope, requestScope, sessionScope or applicationScope.
Also how can we use droplets in ATG like ForEach using JSTL tags only
<dsp:droplet name="ForEach">
<dsp:param name="array" param="catalogItems.rootCategories"/>
<dsp:param name="elementName" value="categoryItem"/>Any ATG droplet is nothing but a servlet which is also a Nucleus component. So essentially you want to call a servlet from JSTL which as such shouldn't be done in a well written script-less JSP. You can probably try to use the droplet as a bean and use JSTL on top of it but since ATG droplets also have different types of parameters like input, output and open so you will have to specially handle those.
