Thanks Vincent.  I finally figured out from Craig Wright's comment ("FOR THOSE 
NEW TO XWIKI") that a)there is such a thing [as a code snippet that runs in a 
page] and that this is one of them.  Being completely unaware of the existence 
of snippets, I would never have guessed that this was one.

I followed step 1:
Step 1: Switch to Filesystem attachments.
I followed step 2:
 Step 2: Add a new directory to your backup routine.
I read step 3:
Step 3: Copy attachments from database to filesystem.
Now you are ready to copy the data over from your database to the filesystem. 
It is prudent to leave the attachments in the database since in most situations 
the attachment data is not bothersome just sitting in the database (The only 
risk of attachments left in the database is that they will bloat the size of 
the database files). As such, this script contains no facility to delete 
entries from the database.
If anything goes wrong in this function, it will fail with an error message and 
you should get the stack trace, keep it to confuse and humiliate the developer 
with. No harm should be done since this only loads from the database and only 
saves to the filesystem.

I read step 4:
Step 4: Make sure everything is working.
Check to make sure your attachments are still there, if an attachment is 
broken, ... 

I felt quite sure that how to run the thing should be in step 3; 2 is too soon, 
and 4 is too late.  But how?  Nowhere in the text does it actually say how to 
run the thing!!!   So I googled looking for other's comments on forums, etc.  I 
YUM installed Groovy and tried running it on the commandline.  I removed the 
leading and trailing lines ("[[grovy]]") which caused errors.  I got class not 
found errors.  I read step 3 again.  I started reading the details of CLASSPATH 
and /bin/build-classpath.  With reluctance and just a little resentment.   It 
was an extwemewy fwustwating expewience.

That said, I realize it the mailing list is for questions, not complaints, and 
so apologize to all for this complaint, and will take it and my other such 
observations to Jira and log them as bugs.

Hi,

I’ve never used this code but shouldn’t it execute in a wiki page?

Thanks

[xwiki-users] Help Request! Running the Attachment Porter

[Douglas Landau]

Folks,

I found the attachment porter but don’t know how to invoke it.  I am reading 
and re-reading the page about it, the page that has the download button.  But 
nowhere does it say how to use it.   

Now, I apologize sincerely for the dumb question.   But I am getting an error 
for every one of 15 or so import lines!   It -must- be necessary to set some 
CLASSPATH or something or specify some JARs on the groovy commandline or 
-some-thing it seems like there -must- be something here that everyone 
thinks is so obvious that it goes without saying...

Could someone please take pity on me and send me their command line that they 
used to run this sucker?

Thank You!
