Controller and URL Rewriting with GaelykServlet

[Nicolas Martignole]

Hi

I'd like to create a front controller for existing URLs such as
/category/java so that it loads category.groovy with a param "java"

1. Do you know if it's possible to set an URL as value for
"resource.name.replacement" ?
for instance something like category.java?c=java

2. When I declare the following configuration for my GaelykServlet
and I restart the server it works the very first time (/category/java
will load category.groovy)
but it won't work if I reload the page.

Thanks

Nicolas

<servlet>
<servlet-name>CategoryServlet</servlet-name>
<servlet-class>groovyx.gaelyk.GaelykServlet</servlet-class>
<init-param>
<param-name>verbose</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>resource.name.replace.all</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<!-- Try to turn /category/java?id=50 to /category.groovy?
c=java -->
<param-name>resource.name.regex</param-name>
<param-value>/(\w*)/*((\w*))(\?.*)?</param-value>
</init-param>
<init-param>
<param-name>resource.name.replacement</param-name>
<param-value>$1.groovy</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>CategoryServlet</servlet-name>
<url-pattern>/category/*</url-pattern>
</servlet-mapping>

Where did resource.name.replacement come from? I have not seen this as a parameter anywhere?

Oups sorry

I was refering the initi-param for GarlykServlet, as shown in gaelyk tutorial where one puts the regexp

This replacement system is described in the tutorial.

The replacement helps finding a resources on disk, somehow.
Think of it as a file path, if you wish.
But it's not a URL, so you can't redirect to a URL with a parameter,
unfortunately.

Which version of Groovy and Gaelyk do you use?

[Nicolas Martignole]

Latest Gaelyk with Groovy 1.6

Ah - right. I haven't looked into that. I forked Gaelyk (its in github/rvowles) and I have a plugin architecture available to our little group. I had to butcher the servlets a bit to make it work the way I want, but essentially you get a filter like mechanism with all the bits you actually need to make pretty much anything work.

I added a slf4j plugin which allows you to add a "log" variable to your binding easily here:

http://github.com/rvowles/gaelyk-plugin-slf4j

I need to test it on the project we are working on, but that is here: 

http://github.com/rvowles/reggae

(registration system for CITCON)

Other examples of plugins that add extra functionality to the category (such as a model object, putAll on entities, etc) - the plugin that registers is here:

http://github.com/rvowles/reggae/blob/master/src/reggae/ControllerPlugin.groovy

the extra Category functionality here (what is good about this is that it keeps you agile, adding category stuff in your own project and refactoring it out when you think you'll need it)

http://github.com/rvowles/reggae/blob/master/src/reggae/ReggaeCategory.groovy

and the new model object that also directly injects its variables into the binding of the gtpl, which makes it really nice to use:

http://github.com/rvowles/reggae/blob/master/src/reggae/GaelykModelBindingEnhancer.groovy

this means you go: model["address"] = address (for example) in your controller, and you can then just go ${address} in your gtpl.

For *your* particular project, the plugin architecture would help as you can intercept the scriptUri, pull it apart, stick the parameters into the binding and then pass the corrected scriptUri through to the next phase. Easy-peasy. You can do any kind of REST-like stuff with it as well.

But this is of course a departure from Gaelyk itself.

Hi,
Gaelyk 0.3 and Groovy 1.6.5 on Mac. I'll double check and will fill a
bug if requiered with the web.xml and the exact usecase

:-)

Thanks Guillaume

Latest Gaelyk certainly means 0.3.1?
And Groovy 1.6 is a bit vague, as there have been many 1.6.x versions :-)
My latest experiments were with Groovy 1.7-beta-2 and the upcoming
1.7-RC-1, and I've not had issues with this last one.
Could you please try the same thing with the upcoming RC-1 from below?
