It is possible to have each element of Alfresco Content Services, including VirtualViewer, installed across separate Tomcat instances.

The example configuration changes below are based on our ACS docker-compose.yml example. VirtualViewer’s content handler and repository AMP need to be configured for this to work properly.

Configuring the Alfresco Content Repository URL in VirtualViewer

VirtualViewer needs to know how to contact the Alfresco Content Repository. Make the following configuration changes to the VirtualViewer tomcat instance.

  1. Install VirtualViewer Alfresco in a tomcat instance if you have not already done so.

  2. Open webapps/virtualviewer/WEB-INF/web.xml and add the following <init-param> to the <servlet> section:

     <init-param>
 	<param-name>alfrescoBaseUrl</param-name>
 	<param-value>http://alfresco:8080/alfresco</param-value>
 </init-param>

  3. Change the URL in <param-value> to the URL where alfresco-content-repository can be reached.

  4. Restart the Tomcat instance.

Configure VirtualViewer’s URL in Alfresco Content Repository AMP

The VirtualViewer snowbound-repo-X.X.AMP in the alfresco-content-repository instance needs to be configured to contact the VirtualViewer AJAX interface.

  1. If you have not already done so, apply the snowbound-repo-X.X.AMP file to the Alfresco Content Repository Tomcat instance.

  2. Open webapps/alfresco/WEB-INF/classes/alfresco/module/snowbound-repo/alfresco-global.properties.

  3. Look for the line containing the property snowbound.cache.servers=.

Set this property to the URL where your VirtualViewer AJAX Servlet can be reached. For example, snowbound.cache.servers=http://vv-alfresco:8080/virtualviewer/AjaxServlet.

  1. Restart the Tomcat instance.
