Directory Generator/Image Directory Generator

[an...@wipro.com]

Hi,



We need to implement a Tree Structure which will have directories of
images as their nodes and on clicking the directory node its
subdirectories (if it is the last then the images) are displayed on the
browser.



We came to know that Cocoon provides Directory Generator which can be
used to provide the above functionality. I am unable to find any
samples/code that explains how to use it. Examples like what should the
XML file contain. Any XSL transformations and where the in the sitemap
should I specify the generator type as directory. Of course I did find
out from the following link something about Directory Generator
http://cocoon.apache.org/2.1/userdocs/generators/directory-generator.htm
l#Example . But this does not help in any way as to get this running in
cocoon.



Any kind of help is greatly appreciated.



Regards,

Anand

Sounds like a simple explorer view. For the directory part the 
DirectoryGenerator is sufficient. For the images you need the 
ImageDirectoryGenerator.

Which XML file? The DirectoryGenerator directly operates on the file 
system. It does not use any XML as input.

There are two (not that obvious) samples in the Cocoon samples:

cocoon-2.1\src\webapp\samples\blocks\sitemap.xmap
cocoon-2.1\src\webapp\samples\test\sitemap.xmap

The latter one generates just the XML of one dir:

<map:generate type="directory" src=".">
     <depth>1</depth>
</map:generate>

while the first one also transforms the XML into another XML:

<map:generate type="directory" src=".">
     <map:parameter name="depth" value="2"/>
</map:generate>
<map:transform src="directory2xsamples.xsl"/>
<map:serialize type="xml"/>

Furthermore there is a directory2html.xslt at 
cocoon-2.1\src\webapp\stylesheets\system, that creates not that nice 
HTML view out of the XML, but it should help.

Feel free to ask more.
