[S2] Freemarker vs struts taglibs
Hi,
I'm a bit confused. I need to decide if I'll use Freemarker or Struts
taglibs, and I don't know the differences between both. E.g. what's the
difference between <s:iterator> and <@s.iterator>, <s:url> and <@s.url>,
etc etc...
I have seen all the tutorials and examples I have found working with
taglibs, but people says WebWork and Struts 2's choice is Freemarker...
Please, help me to understand why taglibs or Freemarker :)
Thanks a lot!
Cheers!

Jordi,
I took your freemarker and JSP code below and implemented it in three
equivalent S2 actions that generated a list of 20 Offers. I then took
some basic performance measurements with JMeter
Test settings:
Http get request directly to the action url
Thread Group: 50 threads, 1 second ramp up period, 100 loops
Gaussian random timer with 100ms deviation and 300ms constant delay offset
Each webapp deployed in the same Tomcat 5.5.17 server on a basic winxp
box (* yes, this is a bad test environment, but at least it was
consistent for the 3 cases)
Case1: Install of S2.0.6 with struts object factory, no optimisations,
JSP result
Result: 5000 Samples, Throughput: 87.8 requests/sec 1139.71 KB/sec
Case2: Install of S2.0.6 with struts object factory, local template
directory and freemarker template update delay of 60000, JSP result
Result: 5000 Samples, Throughput: 89.6 requests/sec 1213.35 KB/sec
Case3: Install of S2.0.6 with struts object factory, freemarker result
Result: 5000 Samples, Throughput: 73.7 requests/sec 579.12 KB/sec
Surprised? I was.
The explanation for Case2 only being marginally faster than Case1 is
that the JSP doesn't include any UIBeans (the templates are hardly used
at all)
An explanation for why Case3 may be so much worse is that using struts
tags within FTL is slower than using them directly in compiled JSP. As
your sample doesn't make use of the UIBeans that use the freemarker
templates its a disadvantage in this case to provide an FTL result.
Repeating the tests yielded consistent relative results on this server.
I can't explain why these are not consistent with your test results.
regards,
Jeromy Evans

That's correct. I have compared both scenarios without considering the first JSP access (I know how JSP works at this level).
Thanks again for your time :)

Hi Jordi, I'm impressed you made the effort to compare Freemarker vs Jsp performance. I've re-posted your question at the top of this email in the hope that it gains the attention of some of the more experienced developers.
In your test did you ensure your comparison doesn't include the first time the JSP is retrieved? On the first request the JSP is converted to java and then compiled which is inevitably slow. Subsequent requests execute the bytecode and are much faster. Did you take this into account?
Within struts2, I think it would be a fair assumption that JSP will always be somewhat slower than pure Freemaker because the UIBeans are rendering using the Freemarker template engine anyway. I wouldn't have imagined it would be <10% slower but have no evidence. I'll try to run the same comparison if I get a spare moment.
Anyone else care to comment?

Extract the Freemarker tag templates; Freemarker doesn't cache them when they're loaded from the classpath.

Re: [S2] Freemarker vs struts taglibs
Posted by Dave Newton <ne...@yahoo.com>.
Extract the Freemarker tag templates; Freemarker
doesn't cache them when they're loaded from the
classpath.

Hi Jordi, I'm impressed you made the effort to compare Freemarker vs Jsp
performance. I've re-posted your question at the top of this email in
the hope that it gains the attention of some of the more experienced
developers.
In your test did you ensure your comparison doesn't include the first
time the JSP is retrieved? On the first request the JSP is converted to
java and then compiled which is inevitably slow. Subsequent requests
execute the bytecode and are much faster. Did you take this into account?
Within struts2, I think it would be a fair assumption that JSP will
always be somewhat slower than pure Freemaker because the UIBeans are
rendering using the Freemarker template engine anyway. I wouldn't have
imagined it would be <10% slower but have no evidence. I'll try to run
the same comparison if I get a spare moment.
Anyone else care to comment?

Hi,
An important info to comment... The total Action execution time is 60ms (again, perhaps the problem is slow taglib execution (?))
Cheers!

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:

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.

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.

Re: [S2] Freemarker vs struts taglibs
Posted by Jeromy Evans <je...@blueskyminds.com.au>.
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.

Re: [S2] Freemarker vs struts taglibs
Posted by Caine Lai <ca...@gmail.com>.
I have been using Freemarker with Struts 2 for my latest project and I'm
loving it. The syntax is a gazillion times (yes, exactly that many) better
than JSP in my opinion.
As far as differences in the tags, there isn't any. You can do the same
thing using the Freemarker Struts tags as you can using the JSP Struts tags.
Just to be clear, you choose to use either JSP or Freemarker. And then you
use the tag syntax for that view language.

FreeMarker is a template engine, with it's own syntax. JSP tags can be
used in FreeMarker, adding some configuration. In the case of Struts
tags, no configuration is required, and you can use them like you would
in JSP except a few differences, see this for details:
