Hi All,
I am havingan issue with REST API on a dspace (5.1 version) on Linux and I
wouldappreciate any help.
You mayfind below a description of my build and deploy procedure:
1. I have downloaded the dspace-source5.1 in a windows environment.
I installed the following:
Java version: 1.8.0_40
Maven version: Apache Maven 3.2.5
Ant version: version 1.9.4
Tomcat version: Apache Tomcat 8.0.18
Postgres version: 9.4.1
2. I have built with maven and run theant scripts (ant fresh_install)
onWindows.
The dspace directory is [dspace]= C:\Dspace
The dspace installation finishes successfully.
3. I have deployed successfully thefollowing apps:
jspui (Note: in order to make jpui to work I had to delete
servlet-api-2.5-20081211.jar from [dspace] \webapps\jspui\WEB-INF\lib
xmlui
oai
solr
rest
Then Iwanted to deploy dspace on a Linux environment, since we intend to use
windowsfor development and building and Linux for a staging and
productionenvironments.
1. I have changed the [dspace]directory in build.properties files to:
dspace.install.dir=/applications/dspace (Because the installationdirectory on
the Linux environment is/applications/dspace)
2. I have built with maven and run theant scripts (ant fresh_install) on
Windows.
3. The dspace installation finishessuccessfully on C:\applications\dspace
4. Then I copy the contents of C:\applications\dspace(from the windows
environment) to /applications/dspace on the Linuxenvironment.
5. I deploy the applications on Tomcatof the Linux Environment.
Java version: 1.8.0_40
Tomcat version: 8.0.18
The following web apps work fine:
· jspui(Note: in order to make jpui to work I had to delete
servlet-api-2.5-20081211.jar from [dspace] \webapps\jspui\WEB-INF\lib
· xmlui
· oai
· solr
But the rest application is not working and Iget the following error:
(Please note that I have the same error in Dspace 5.0 as well) type Exception
