[dspace-tech] Browse by and Sidebar facet for Series

[euler]

Dear All,

I received a request to add a Browse by and sidebar facet for series in the 
repository I'm working on. The problem is that the series field contains 1) 
Series statement and 2) Volume number/sequential designation. For example, 
Technical report ; no. 1, Technical report ; no. 2, Technical report ; no. 
3, and so on and so forth. If I create a new browse by index and sidebar 
facet for the series statement, it will not aggregate the series title 
Technical report but will instead create individual entries for each series 
number. So my question is how to aggregate the series entries in the browse 
by index and sidebar facets?

Thanks in advance,
euler

[dspace-tech] Re: Installation problem

[Kim Shepherd]

Hi Nico, it's hard to diagnose this problem exactly... although the problem 
seems to be that you're getting back a null Hibernate session for the 
context, I'd say your postgres database connections should be OK since your 
ant fresh_install finished successfully, which includes lots of db writes 
and checks, so I think the problem area could be the way the 
webapps/context are deployed in Tomcat and/or their references to 
dspace.home or dspace.config.

Could you share some more information such as
- which log is this exception from?
- how is Tomcat is configured to point to the xmlui and solr webapps? 
- are there any other deployment / startup errors or warnings in your raw 
catalina logs?

Cheers

Kim

Re: [dspace-tech] Access Database without Hibernate

[Tim Donohue]

Hi Tiago,

The DatabaseManager was replaced by the new Database Access Object (DAO)
Layer in DSpace 6.x.  So, now you need to use the appropriate DAO object to
query the database table that you wish to query (as there are now DAOs for
each database table).  For much more information on this, see the DSpace 6
Service API notes at:
https://wiki.duraspace.org/display/DSPACE/DSpace+Service+based+api#DSpaceServicebasedapi-Servicebasedapi
(There are also many examples linked to from the bottom of that wiki page.)

So, there is no direct replacement for DatabaseManager. But, if you wanted
to query the "item" table (for example), you'd now use
the org.dspace.content.dao.ItemDAO class to do so:
https://github.com/DSpace/DSpace/blob/master/dspace-api/src/main/java/org/dspace/content/dao/impl/ItemDAOImpl.java

Hope that helps. If you have more specific questions, please feel free to
ask them on this list.  We fully realize this new model will take getting
used to, but it provides much more stability and separation of concerns
than our old way of using the DatabaseManager for all queries.

Tim

Re: [dspace-tech] Does '$/dspace database clean' affects configuration-tool-demo.xls ?

[Pascarelli Luigi Andrea]

Yes, you have to run again the load-cris-configuration script.

Hope this helps you.

Best,

[dspace-tech] Re: Internal System Error - HTTP Status 500

[snemi]

Maybe your solr index is corrupt or locked by .lock file. Maybe delete 
C:\dspace\solr\search\data\index\


and try to create new index with dspace index-discovery -b

[dspace-tech] Does '$/dspace database clean' affects configuration-tool-demo.xls ?

[Lluís Madurell Alemany]

If running [dspace]/bin/dspace database clean

Do you need to run again (2 times) dspace load-cris-configuration -f 
[dspace]/etc/configuration-tool-demo.xls ?

[dspace-tech] Re: Changing default sorting in search

[eanasagasti]

Thanks a lot! It worked.

I uncomented the line in 
*[dspace-install-dir]/config/spring/api/discovery.xml*
Then rebuilt the index:
*./dspace index-discovery -b*
And then restarted the web server, in our case Tomcat7:
*/etc/init.d/tomcat7 restart*
