Re: [Dspace-tech] REST API query, sort

Wesley,
For problem 1, what are you seeing in your DSpace logs?  In your  
Catalina logs? Have you checked them for SQL or database errors?

Re: [Dspace-tech] Rest api

2012-03-05 Thread maurice . bouchard

Are you using Postgres or Oracle? When I installed the REST API a  
couple of weeks ago, I encountered the 500 internal server errors as  
well.  I solved them by placing the ojdbc14.jar in my CLASSPATH (I am  
using Oracle).  If you're using Postgres there may be an analogous  
fix.  Keep in mind, the REST API is not using the same db connection  
mechanism, at least for Oracle, as dSpace proper.

[Dspace-tech] REST API metadata elements not populated from a collection level query

2012-02-23 Thread maurice . bouchard

Greetings,
When I issue a collection level query such as:  
http://192.168.56.111:8008/rest/collections/22.xml I get all items in  
collection 22 (as expected) but the individual item level   
fields are empty, as in:

0


0


0


0

When I issue an item level query such as  
http://192.168.56.111:8008/rest/items.xml I get all the items in all  
collections (as expected) but the metadata elements are populated, as

This has to be related to https://jira.duraspace.org/browse/DS-922  I  
am using DSpace 1.8 and the latest version of the REST API.  I  
understand that the module is experimental but if this is easy to fix,  
that would be much appreciated. I'm not a java programmer but I am  
happy to help however I can.

Thanks very much.

Re: [Dspace-tech] DSpace REST API: SQL error (500)

2012-02-23 Thread maurice . bouchard

I solved this problem.

The REST API is using class oracle.jdbc.OracleDriver which is found in  
the ojdbc14.jar  This jar was not in my classpath.  I copied it to  
$JAVA_HOME/jre/lib/ext and after that, the API works.  Everything is  
obvious in retrospect but I am still confused as to why my  
dspace-1.8.0 install was working perfectly well with jspui and xmlui,  
both happily populating my oracle tables. Clearly, these apps are  
using a different db connection mechanism (i.e., db.url found in  
dspace.cfg) than the REST API.  Is there a technical reason why the  
API couldn't use the same mechanism?

Re: [Dspace-tech] DSpace REST API: SQL error (500)

2012-02-22 Thread maurice . bouchard

Thanks for the response, but I'm not sure what I'm looking in that  
java file. In the startProviders method, I found the following code:
// for dev testing only COMMENT IN WORKING ENVIRONMENT
 if (config.contains("dspace.dir")) {
 config = "/devel/dspace/config/dspace.cfg";
 }

which was *not* commented so I commented that code and rebuilt.   
Sadly, there was no change in the behavior.

The method builds the entityProvider list.  Is there supposed to be a  
database initialization there?  That seems unlikely.  If the web.xml  
file under the dspace-rest/webapp/WEB-INF directory points at my  
dspace.cfg, why wouldn't it connect to the database using the jdbc  
connect in db.url?  I noticed the pom.xml for the dspace-rest code has  
ojdbc14 under Oracle db support.  Is that correct?

[Dspace-tech] DSpace REST API: SQL error (500)

2012-02-22 Thread maurice . bouchard

Hello,
I am attempting to use the REST API against a test repository. I am  
using dspace 1.8.0 and Oracle express.  My repository is working fine  
(using the xmlui, I can add, change, and view communities,  
collections, and items).  I've checked out and built the REST API  
after having changed its web.xml to point at my dspace.cfg. I can get  
to all the documentation (e.g.,  
http://192.168.56.111:8008/rest/describe and yes, I am using port 8008  
since oracle apex is listening on 8080). When I attempt to retrieve  
any communities (e.g.,  
http://192.168.56.111:8008/rest/communities.xml), collections, or  
items, in either json or xml format, I get 500 - Internal server  
errors.  The tomcat (v6.0.33) log shows:

Setting the REST servlet context to: /rest
Setting the manager servlet context to: /rest
stor2/communities.xml

I've inherited a DSpace 1.6.1 repository and we're having problems  
with the XMLUI.  Specifically, variable *names* like  
xmlui.ArtifactBrowser.FrontPageSearch.para1 for example are displaying

xmlui.general.dspace_home





 

xmlui.general.dspace_home

xmlui.general.dspace_home

I've checked the tech list archives and Nabble but haven't found this  
problem reported before.  We have likely misconfigured something but,  
after several hours of searching and educating myself on jetty,  
dspace, log4j, etc I'm at a loss. Has anyone seen this before?  I'd  
appreciate some advice on where to look.

Thanks very much.
