Re: [Dspace-tech] LNI/WebDAV : GET returns 501
Thanks a million. I got lookup and get working today after fooling
around with wget. I'm glad you told me about not following the
redirects, or I'd have been scratching my head over 400 errors still.
I'm not using PERL; I am using C#.

Subject: RE: [Dspace-tech] LNI/WebDAV : GET returns 501
You can see how the lookup feature works by using a simple HTTP client
like the GNU "wget" application to do a GET, and reading its diagnostic
output.. for example, this does a lookup of handle 123456789/1
using HTTP Basic authentication to login (assuming you have
username/password
login on your server):
wget [EMAIL PROTECTED] --http-password=PASSWORD -S
http://MYDSPACE.mit.edu:8080/lni/dav/lookup/handle/123456789/1
Now, watch the headers -- the request as a whole will fail because
"wget"
is aggressive about responding to the HTTP 302 status with another GET
on
the real resource, but that GET probably isn't allowed or is missing
some
option. Anyway, just look for the Location: header in the first
response:

This ought to show how to implement what you need with Apache HTTPClient
or something like that.
You're not using Perl, are you? The WebDAV library on CPAN was horribly
broken last I looked, not really usable for this at all.
Also, note that you don't *need* to go through the hierarchy to get at
any Handle in the archive. If you already have the Handle of the
resource
you're looking for, just do a "lookup" to get its URL and use that.
Traversing the hierarchy is just for exploring, and because it's the
model of HTTP and WebDAV.

Subject: Re: [Dspace-tech] LNI/WebDAV : GET returns 501
GET only works on Items and Bitstreams, so if you get the resource path
to a Bitstream from PROPFIND (depth=1) on an Item, then you ought to be
able
to do a GET on it and receive its contents.
This path looks like you've traversed some communities and collections:
>
http://[server]:8080/lni/dav/dso_123456789%241/dso_123456789%242/dso_123
456789%243
You can also get a resource URL by doing a "lookup" on a Handle, e.g.
GET
on http://[server]:8080/lni/dav/lookup/handle/123456789/42
returns a Location: header with the URL. I don't think it works on
Bitstreams, though.
Anyway, if you do a PROPFIND on that resource you're trying to GET, look
at the value for "type" (in the "http://www.dspace.org/xmlns/dspace";
namespace).
It'll be an empty element for the DSpace object type, either
,
, ,
Typically, the Bitstream resources have a path ending in
/bitstream_{n}.{suffix}, e.g. .../bitstream_3.pdf
So, I think the problem here is that you've got a resource for which
GET isn't implemented.
For some sketchy doc which is unfortunately the best available, see

[Dspace-tech] Creating a WSDL file for LNI
Hi - I have been fighting with this for about three days now, so I'm giving up the thought that I can figure it out on my own. I want to call LNI from a .NET client, so I need a WSDL file (at least, I think I do). I've been trying to create one using the Axis JAVA2WSDL command, but I'm always getting a "Class not found" error. Speaking of which, I assume that the class I'd want to do this to is LNISoapServlet.java... Has anybody done this successfully and, if so, can you tell me how you did it? - Rick - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Dspace-tech] LNI - no index.html; "The requested resource (/lni/) is not available"
lni is right there in the Tomcat webapps folder right beside xmlui, which works like a champ. I'm not experienced with web apps, and even less so with java web apps, so I'm at something of a loss here. I've spent a while reading and trying to figure out the problem, with not much success. Mostly, it seems like there should be an index.html file in the WEB-INF directory, but there's not one. Anybody got lni working who'd like to give me a hint? - Rick - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Dspace-tech] xmlui: "The requested resource (/dspace/forgot) is not available" - [also, (/dspace/register) is not available]
Hi - I'm trying to create some non-administrator users in DSpace 1.5, which goes OK until they try to follow the link in the email. Then they get a 404 error, whose description is "The requested resource (/dspace/forgot) is not available." I have more or less the same problem when a user tries to self-register, but the message is "The requested resource (/dspace/register) is not available." I found a message <http://mailman.mit.edu/pipermail/dspace-general/2006-November/001160.ht ml> from Nov 2006 on DSpace-general, where somebody had a similar problem, but that seemed to be a path issue, which I don't think is my problem. I also saw bug 1606456 in the KNOWN_BUGS file, but I can't tell whether that's really it, either. I searched for files with "register" in their names in my [dspace-source] directory, and found a dozen or so of them in directories with jspui somewhere in the path, but none where xmlui was in the path. I'm using the xmlui and just for the hell of right now, the Kubrick theme. I did find some Java code in eperson under xmlui, but that wouldn't have anything to do with a path problem. I think. Is the solution to my problem obvious to anyone? Thanks - Rick Runyan - Check out the new SourceForge.net Marketplace.

Re: [Dspace-tech] Oracle and DSpace 1.5 and "ILIKE"
Cool. A fix *and* and explanation! How can you beat that?
By the way, if you're actually fixing the real code, there are more

public static EPerson[] search(Context context, String query, int

Subject: Re: [Dspace-tech] Oracle and DSpace 1.5 and "ILIKE"
Hi,
I think it worked in 1.4.2 only if you used the default jspui interface
(it doesn't call searchResultCount). Manakin/xmlui on the other hand
does call it, so it breaks.
I altered the code to be oracle friendly:
TableRow row = DatabaseManager.querySingle(context,
"SELECT count(*) as count FROM eperson WHERE eperson_id = ? OR " +
"lower(firstname) LIKE ? OR lower(lastname) LIKE ? OR lower(email) LIKE
?",
new Object[] {int_param,dbquery,dbquery,dbquery});
I assume that would work in postgres as well, but I haven't tested it.
You would also have to make a similar change in Group.java as well.
I haven't looked too closely at 1.5, but it works in 1.4.2.
Hope this helps.

[Dspace-tech] Oracle and DSpace 1.5 and "ILIKE"
Hi -
I'm trying to install DSpace 1.5 using Oracle. It wasn't until
yesterday that I saw this in the KNOWN_BUGS file:
"Oracle compatibility: this release does not support Oracle. Check for
patches or updates to this release to restore Oracle compatibility."
But nevertheless, I thought I had read that people had done successful
installs using Oracle, and I wound up also getting it installed OK, but
now I'm running into a problem in the eperson code when I click the
"People" link under "Access Control."
Specifically, I get this exception:
java.sql.SQLException: ORA-00920: invalid relational operator
and looking through the stack trace, it appears to be coming from
org.dspace.eperson.EPerson.searchResultCount(EPerson.java:326)
where it says
TableRow row = DatabaseManager.querySingle(context,
"SELECT count(*) as count FROM eperson WHERE
eperson_id = ? OR " +
"firstname ILIKE ? OR lastname ILIKE ? OR email
ILIKE ?",
new Object[]
{int_param,dbquery,dbquery,dbquery});
I'm pretty sure "ILIKE" doesn't work in Oracle, but I see this in the
1.4.2 code and I'm pretty sure I was able t create some users in that.
Does anybody have any idea about what's wrong here?
Thanks,
Rick Runyan

Re: [Dspace-tech] Pluggable Storage Question(s)
Richard - Thanks for your reply. I actually posted something on the discussion page of the Pluggable Storage wiki last August, but apparently it hasn't garnered many glances (http://wiki.dspace.org/index.php/Talk:PluggableStorage). I considered those same possibilities, but they all led to other cans of worms, particularly since we're expecting to see some really big files (well, too big for memory, anyway). I'd be happy to have you look at my code. I have no experience in the open-source world, and I wasn't sure how I could contribute what I'd done in case anybody might be interested, but maybe this is how. What would be the best thing to do (after I give it the once-over to remove any obvious stupidisms and lazy hacks)?

There are indeed issues with DB connection management - which is why I didn't add a RDBMS implementation at the outset.

[Dspace-tech] Pluggable Storage Question(s)
Hi - I used the Pluggable Storage interface to modify a 1.4.2 test installation to store bitstreams as blobs in an Oracle database. I'm curious as to whether anybody has moved a working PS implementation to 1.5. Also, about my implementation - I had to modify the interface so that the bitstore methods' callers would pass in their Context. Strictly speaking, this was necessary only for the 'get' method. The problem I had is that when those methods manage their own connections, they have to close them before they return. That meant the connection to the blob stream was closed before get's caller could begin reading it. Has anybody encountered a similar problem? Am I overlooking some painfully simple solution? - Rick Runyan - This SF.net email is sponsored by: Microsoft Defy all challenges.
