Step 8. Enable the DSpace Java webapps on the Java Tomcat webapp server

The DSpace webapps have been compiled in the /home/dspace/webapps folder but Tomcat only serves up webapps in the /var/lib/tomcat6/webapps folder.

So, how do we get all the files into the Tomcat webapps folder ?

There are several methods, but we are going to set it up so that if you change anything in the DSpace /home/dspace/webapps folder and then re-compile, the changes automatically occur in the Tomcat /var/lib/tomcat6/webapps folder. This also saves you from constantly copying webapps after a compile, which is a tricky business.

We create shortcuts (symlinks in the Unix world) to the DSpace webapps, in the default Tomcat webapps folder, by typing as follows:

cd /var/lib/tomcat6/webapps

sudo ln -s /home/dspace/webapps/oai

sudo ln -s /home/dspace/webapps/solr

sudo ln -s /home/dspace/webapps/sword

sudo ln -s /usr/share/tomcat6-admin/manager

Step 8.1 Configure the default ROOT webapp

DSpace has two web interfaces, the XMLUI and the JSPUI. This procedure allows you to select which inteface will be used as the ROOT webapp. In other words, the one that does not need a /XMLUI or a /JSPUI URL addition.

Start by removing the default Tomcat ROOT webapp with the following command:

sudo rm -rf /var/lib/tomcat6/webapps/ROOT

Then apply one of the following.

• Please note: You can only choose one option.

Option A: Type the following to make the XMLUI the default interface. Complex setup but very configurable and has a low server load.

cd /var/lib/tomcat6/webapps

sudo ln -s /home/dspace/webapps/xmlui ROOT

Option B: Type the following to make the JSPUI the default interface. Easy to setup but hard to customise and has a high server load.

cd /var/lib/tomcat6/webapps

sudo ln -s /home/dspace/webapps/jspui ROOT

Example listing of DSpace Java webapps in the Tomcat webapp folder

dspace@ir1:/var/lib/tomcat6/webapps$ ls -l
total 0
lrwxrwxrwx 1 root    root         32 2012-09-05 11:27 manager -> /usr/share/tomcat6-admin/manager
lrwxrwxrwx 1 root    root         24 2012-09-05 11:28 oai -> /home/dspace/webapps/oai
lrwxrwxrwx 1 root    root         26 2012-09-05 11:29 ROOT -> /home/dspace/webapps/xmlui
lrwxrwxrwx 1 root    root         25 2012-09-05 11:28 solr -> /home/dspace/webapps/solr
lrwxrwxrwx 1 root    root         26 2012-09-05 11:29 sword -> /home/dspace/webapps/sword

Previously we ran both the XMLUI and JSPUI and now only run the XMLUI as the ROOT interface. The JSPUI seemed to consume a lot of memory.

Step 8.2 Restart Tomcat Server

Type the following.

sudo /etc/init.d/tomcat6 restart
