I have (attempted to) create a WebDAV service for Turbine. I would
appreciate comments and suggestions as I am a novice coder, so please
don't take it to hard on me if it sucks. You can find the three files
at <http://www.eastnode.com>. Hopefully the javadoc explains it a
little... But heres what I'm doing with it (A lot more can be done, I
think).
I get a directory listing like so:
Vector webdavfiles = WebdavService.getWebdavFiles( "/some/directory/" );
context.put("directory", webdavfiles);
data.getUser().setTemp("wfiles", webdavfiles); // This is explained
further on
Then in my velocity file I do something like:
#foreach ($item in $directory)
#if ($item.isDirectory())
<tr>
<td>
<input type=checkbox name="wfile_$item.getHashcode()"></td>
<td><a
href="$link.setPage("Collab,Files.vm").addPathInfo("moveto",
$item.getFilename()).addPathInfo("currpath",
$currpath).addPathInfo("JobId", $job.getJobId() )"><img
src="#getContextURL('/images/folder.gif')" border="0" height="16"
width="16"></a></td>
<td> <a
href="$link.setPage("Collab,Files.vm").addPathInfo("moveto",
$item.getFilename()).addPathInfo("currpath",
$currpath).addPathInfo("JobId", $job.getJobId() )">
$item.getFilename()/</a> </td>
<td"> </td>
<td>$item.getDisplayDate()</td>
<td>$!item.getProperty("user") </td>
<td>$!item.getProperty("descr") </td>
</tr>
#else
<tr>
<td>
<input type=checkbox name="wfile_$item.getHashcode()"></td>
<td><a
href="$link.setScreen("Collab.RetrieveFile").addPathInfo("currpath",
$currpath).addPathInfo("JobId", $job.getJobId()
).addPathInfo("filename", $item.getFilename())"><img
src="#getContextURL('/images/file.gif')" border="0" height="16"
width="16"></a></td>
<td><a
href="$link.setScreen("Collab.RetrieveFile").addPathInfo("currpath",
$currpath).addPathInfo("JobId", $job.getJobId()
).addPathInfo("filename", $item.getFilename())">
$item.getFilename() </a></td>
<td>$item.getDisplaySize()</td>
<td>$item.getDisplayDate()</td>
<td>$!item.getProperty("user") </td>
<td>$!item.getProperty("descr") </td>
</tr>
#end
#end
The checkboxes are to mark for delete and for move. I have delete
button and a move button with a dropdown list of folders that use these
checkboxes.
NOTE: The getHashcode() method is used to prevent case conflicts with
filenames so "test" and "TEST" don't conflict when marking for a move or
delete.
If the user executes the delete action the following code then deletes
the files:
WebdavParameterParser wpp = (WebdavParameterParser) data.getParameters();
Vector wfiles = (Vector) data.getUser().getTemp("wfiles");
wpp.markDeleteWebdavFiles(wfiles);
WebdavService.delete(wfiles, path_of_files);
Similarly a move goes:
WebdavParameterParser wpp = (WebdavParameterParser) data.getParameters();
Vector wfiles = (Vector) data.getUser().getTemp("wfiles");
wpp.markMoveWebdavFiles(wfiles);
WebdavService.delete(wfiles, current_path, destination_path);
Also you'll notice in WebdavService there are some methods to store
FileItems and create new directories. This whole service is a lower
abstraction of my collaboration mechanism that I'm working on (which is
very app-specific, or I'd release it).
I hope you all can make sense of this and find it useful. If it is
worth using long-term in turbine I'll release it under the apache
license (but I know it needs work probably :) ).
