Aspects in tapestry pages using spring
Hi,
I want to log the time users spend on individual pages in tapestry to a
database. I'm thinking the best way to do this may be to define an
aspect (using aspectj) on the attach() method for each page. I'm using
spring for the business/dao layers. As the tapestry pages are not
themselves defined in the spring application context I'm having a hard
time coming up with a suitable aspect that can be
a) defined to run on all attach() methods in any class that extends
BasePage, and
b) into which I can inject the spring bean which provides an interface
to the database where the logs must be stored.
I can accomplish a) by using a simple aspectj aspect, and b) by using a
spring defined aspect, but I'm not sure how to accomplish both at once.
Am I overlooking something stupid?
Thanks
Denis

Thanks for that James - using a filter is a better approach than aspectj
in this instance. I'm not too hot on hivemind. Is there any service
point or extension I can use to get the current page's name? I have a
request filter for implementing the open session in view filter in
hibernate already, and I can get the actual URL from the
WebRequest.getPathInfo() method, but I'm not sure how to get the page
class name itself. Any idea for how to get this using hivemind?
Thanks a lot for your help

Re: Limit the number of clicks per second inside Tapestry
Posted by mu...@fantasymail.de.
Thanks for the input!
It is primarily intended to get rid auf Apache modules that did that before and to be more flexible in using that information.
Search engines crawlers can usually slow down a website a lot - or experimental crawlers by university students etc....or malicious webcrawlers or people who download your website for offline viewing.
I think restricting it to 1 page view per second would be enough - certain ip addresses could get a higher "bandwidth".
Instead of sending them to an error page, however, I would just let the request time out.....
The good thing would be you could write your own profiling application and log those ipaddresses and clients that are bandwidth hungry....
The only question is, whether such a Tapestry implementation would be efficient or not....maybe this would consume too much memory itself if there are many visitors on a website?

Re: Limit the number of clicks per second inside Tapestry

I believe you could create a filter (in Tapestry 4) that could
intercept requests and work with a session-based object. The session
object would need to keep a list of timestamps of recent accesses.
With this, it could determine if a user has slipped over your
threshold, at which point you could, say, redirect the user to a
static HTML page warning them of their transgression.
These filters can be added to Tapestry's WebRequestProcessor pipeline.
I'd love to know what your underlying use-case is.

If I want to limit the number of clicks page views per second for every user,
how would I do that inside Tapestry?
Would that go into the BaseEngine ?

Re: Aspects in tapestry pages using spring
Posted by James Carman <ja...@carmanconsulting.com>.
Well, it depends on your pointcut, I guess. If it can be woven into
your code properly, you don't need to recompile Tapestry. However,
you might want to look into putting an interceptor on the page service
or introducing a web request servicer filter. That's an easy way to
do cross-cutting concerns.

Re: Aspects in tapestry pages using spring
Posted by Denis McCarthy <dm...@annadaletech.com>.
Thanks for that James. I've got the aspectj stuff working now. The
reason why I've been looking into aspectj is to log the length of time
users of my site spend on individual pages. I want to log when each page
is rendered for a particular user's session, giving me a record of how
long a user spent on any individual page (this information is important
to me because the application is a touch-screen application, and if any
screen is slowing down or frightening users away because of its
complexity I want to know about it)
As this is a stereotypical cross-cutting concern, I've been looking for
a nice way to log this using tapestry's own internals. However, if I
understand aop correctly I'll have to compile tapestry itself using ajc
with my aspect to weave the aspect into the tapestry code. This could be
a little over the top - I'm wondering is there some less invasive way to
record page loads per session without resorting to copying and pasting
the same code into every page to accomplish this? Is there something in
hivemind that'll allow me to record this information?
Thanks

Re: Aspects in tapestry pages using spring
Posted by James Carman <ja...@carmanconsulting.com>.
You can also use AspectJ within Tapestry using hivemind-aspectj (at
JavaForge). You still have to make sure you weave the aspects into
your code, but hivemind-aspectj can inject HiveMind services into your
singleton (the default) AspectJ aspects. That way, you can inject all
of Tapestry's HiveMind goodies into your aspects in case you need them
(which you probably will). If you want more information, email me
back and I'll see if I can give you an example (the test cases are
quite slim, but they do show how it's used).

Re: Aspects in tapestry pages using spring
Posted by Ivano <i....@mclink.it>.
Once you have accomplished the task (a), the task (b) can be solved as
follows.
You need to define the aspect as a SpringBean (only in spring 2, of
course) using something like:
<bean id="yourAspect" class="your.company.aspects.AspectClass"
factory-method="aspectOf" lazy-init="false">
<property name="yourDatasource" ref="myDataSourceBeanId"/>
</bean>
in your applicationContext.xml file.
Then you need to weave your project classes with the aspect you made
(e.g. configuring Eclipse to do it if you use that.).
Don't forget to deploy the aspect class with your application.
