The Handle server you use must be dedicated to resolve Handles from DSpace. You cannot use a Handle server that is in use with other software already. You can use CNRI's Handle Software -- all you have to do is to add to it a plugin that is provided by DSpace. The following instructions were tested with CNRI's Handle software version 9.1.0. You can do the following steps on another machine than the machine DSpace runs on, but you have to copy some files from the machine on which DSpace is installed.

1. Set the following two configuration properties for every DSpace backend that your are running:

   Code Block
   title DSpace backend configuration to activate the endpoints used by the remote handle resolver
   handle.remote-resolver.enabled = true handle.hide.listhandles = false

   
   

2. Download the CNRI Handle Software: http:s//www.handle.net/download.html. In the tarball you'll find an README.txt with installation instructions -- follow it.
3. After installing the CNRI Handle Software you should have two directories: once that contains the CNRI software and one that contains the configuration of you local Handle Server. For the rest of this instruction we assume that the directory containing the CNRI Software is /hs/handle-9.1.0 and the directory containing the configuration of your local server is /hs/srv_1.  (We use the same paths here as CNRIs README.txt.)
4. Download the plugin from https://github.com/DSpace/Remote-Handle-Resolver/releases.  Select a release.  You can get the source and build it yourself, or just use the JAR file included in the release.  In either case, once you have a dspace-remote-handle-resolver-VERSION.jar, copy it to the directory containing the CNRI software (/hs/handle-9.1.0/lib). 
5. Create the directory /hs/srv_1/logs.

6. Create the following two files in /hs/srv_1.

   Code Block
   title log4j-handle-plugin.properties
   log4j.rootCategory=INFO, A1 log4j.appender.A1=org.apache.log4j.DailyRollingFileAppender log4j.appender.A1.File=/hs/srv_1/logs/handle-plugin.log log4j.appender.A1.DatePattern= '.' yyyy-MM-dd log4j.appender.A1.layout=org.apache.log4j.PatternLayout log4j.appender.A1.layout.ConversionPattern=%d %-5p %c @ %m%n log4j.logger.org.apache.axis.handlers.http.HTTPAuthHandler=INFO

   Change the path in the third line, if necessary. It must point to the DSpace 7 Rest API (as configured in $dspace.server.url).

   Code Block
   title handle-dspace-plugin.cfg
   dspace.handle.endpoint1 = http: //dspace.example.org/server

   If you run more than one DSpace Installation, you may add more DSpace Endpoints.  Just increase the number at the end of the key for each:  endpoint2, endpoint3....

7. Edit the file /hs/srv_1/config.dct to include the following lines in the " server_config" clause:

   Code Block
   "storage_type" = "CUSTOM" "storage_class" = "org.dspace.handle.MultiRemoteDSpaceRepositoryHandlePlugin"

   
   

8. Edit /hs/handle-9.1.0/bin/hdl:
   1. Find a line that contains exec java ... net.handle.server.Main ...
   2. Add "-Dlog4j.configuration=file:///hs/srv_1/log4j-handle-plugin.properties -Ddspace.handle.plugin.configuration=/hs/srv_1/handle-dspace-plugin.cfg" right in front of net.handle.server.Main.
9. If your handle server is running, restart it.
