 Description   

It would be nice if Spring had support for jsp taglibs like f.x.

<#assign tolog=JspTaglibs["/WEB-INF/jsp/tolog.tld"]>

as decribed on http://fmpp.sourceforge.net/freemarker/pgui_misc_servlet.html (see the heading "Using JSP custom tags in FTL")

I wrote an article about this: http://opensource.atlassian.com/confluence/spring/display/INTEGRATE/Using+JSP+taglibs+with+FreeMarkerView

Source code from the article.

FYI, I received this email from someone who's been using the code in my article:

Hi Tom,

Just an update on your code to get JspTaglibs working in Spring
Freemarker installations.....

It seems to work flawlessly. I've migrated all of my functionality to
use the code and seen no problems.

It seems to a good piece of work - I encourage you to get this into
Spring, it something I know that I want, something in the Spring JIRA,
and something I know a few other J2EE people want.

Thanks for a fine piece of work,
Dean.

I tested this implementation. I had to create a new view resolver to make this work the way I needed.

It works great.

All,

I updated FreeMarkerView and FreeMarkerConfigurer as appropriate so this should now just work. Can anyone who needs this feature please try it out. I gave it a basic run in a local Tomcat but feedback from a real usage scenario would be great.

Rob,

I've just replaced all usages of TaglibFreeMarkerView with the regular FreeMarkerView in several of our real-world applications which heavily use the taglib functionality, and it seems to work just fine! Waiting for RC1 to deploy into production...

To quote Homer, "Holy Macaroni!". Integrating both Erik's and Tom's code gives me JspTaglibs access in my out of the box spring + freemarker setup. Thanks very much! (and to the rest of the Spring folks too!)

This JspTaglibs support really needs to be made a part of Spring, or made into a filter. Immediately after discovering the no-taglibs limitation with the out of the box Spring integration, I felt like I had to drop FreeMarker...that was a "deal breaker".

I opted to drop Tom's Views.properties and go with Erik's bean config xml. Here's mine:

<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="templateLoaderPath" value="/WEB-INF/ftl/"/>
</bean>
<bean id="freemarkerServletContextModel"
class="springext.web.servlet.view.freemarker.support.ServletContextModelFactoryBean"/>
<bean id="freemarkerTaglibFactory"
class="springext.web.servlet.view.freemarker.support.TaglibFactoryBean"/>
<bean id="viewResolver"
class="springext.web.servlet.view.freemarker.TaglibFreeMarkerViewResolver">
<property name="servletContextModel" ref="freemarkerServletContextModel" />
<property name="taglibFactory" ref="freemarkerTaglibFactory" />
<property name="cache" value="true" />
<property name="prefix" value="" />
<property name="suffix" value=".ftl" />
<property name="exposeSpringMacroHelpers"
value="true" />
</bean>

FYI I am still on 1.2.6, not sure about jumping to 2.0, worried about destabilization.... Cheers.
