Hi Jeromy,
I apologize to respond this email so late.
I've develop a little test portal (close in functionality to production
portal), and I've notice that JSP taglib are slower that Freemarker equivalent
page (I'm speaking about a JSP result page rendered in 1.2s and the same page
rendered with freemarker in 600ms).
It's certain that there are a lot of JSP taglib documentation and S2 forums,
but in a production site it's critical an excellent time response.
I don't know if I'm doing anything wrong... I show you a little fragment of
test code in JSP taglibs an Freemarker:
***************** JSP taglibs **********************
<s:iterator value="offers">
<tr>
<td>
<s:url id="curUrl" action="Redirect"
includeParams="none">
<s:param name="url"><s:property
value="offUrl"/></s:param>
</s:url>
<a href="${curUrl}"><s:property
value="offTitle"/></a><br>
<s:if test="%{offCompany != null}">
<b><s:text
name="Results.company"/></b>: <s:property value="offCompany"/><br>
</s:if>
<s:if test="%{offSalary != null}">
<b><s:text
name="Results.salary"/></b>: <s:property value="offSalary"/><br>
</s:if>
<s:property value="offDescr"/><br>
<s:url id="addToShortListUrl"
action="ShortList!add" includeParams="none">
<s:param name="offId"><s:property
value="offId"/></s:param>
</s:url>
<a href="${addToShortListUrl}"><s:text
name="Results.addToShortList"/></a><br><br>
</td>
</tr>
</s:iterator>
******************** FREMARKER ************************
<#list offers as o>
<tr>
<td>
<@s.url id="curUrl" action="Redirect"
includeParams="none" url="${o.offUrl}" />
<a href="${curUrl}">${o.offTitle}</a><br>
<#if o.offCompany != "">
<b><@s.text
name="Results.company"/></b>: ${o.offCompany}<br>
</#if>
<#if o.offSalary != "">
<b><@s.text
name="Results.salary"/></b>: ${o.offSalary}<br>
</#if>
${o.offDescr}<br>
<@s.url id="addToShortListUrl"
action="ShortList!add" includeParams="none" offId="${o.offId}" />
<a href="${addToShortListUrl}"><@s.text
name="Results.addToShortList"/></a><br><br>
</td>
</tr>
</#list>
Is JSP taglib an slow and not recommended solution for production portals?
Thanks a lot for your patience :)
Best regards!

Asunto: Re: [S2] Freemarker vs struts taglibs
If you're a new user of Struts2 and JSP then I suggest you simply start with
JSP as there's far more resources and tutorials available.
You only must become aware of Freemarker once you wish to extend the default
themes.
Within Struts2, by default Freemarker templates are used when rendering the UI
components (ie. the S2 taglib classes that extend AbstractUITag such as
TextField).
eg. if you use the <s:textfield> tag, Struts2 will render it using the text.ftl
template for the specified/current theme.
Eventually you may wish to extend the theme (change with the way <s:textfield>
is rendered) at which time you'll probably create your own templates for the UI
components-of-interested and start using Freemarker.
Eventually may you also wish to create your own taglib UI components following
the the S2 conventions in which case you'd follow the same template approach
(but Struts2 does not preclude you from using any other JSP/taglib convention).
As mentioned in previous responses and the link below, Struts2 allows you to
use entire Freemarker page results instead of JSP. There are good technical
arguments for using Freemarker instead of JSP, but generally speaking right now
you'll find more people to help, initially less effort, more jobs and better
IDE-support with JSP and almost everything you learn with JSP can be later be
applied within the Freemarker context.
