External tab document extension

The External Tab Document feature helps you show tab content in a properties tab based on an external URL request when a node document is selected.

Field / Property Type Description
extension.external.tab.document List Each row is a pair of values with a tab content declaration; the format is: name;url
name1;http://localhost:8180/openkm/test.jsp
name2;http://www.openkm.com
When you embed a URL in an iframe that belongs to a subdomain different from the application’s domain, you must include that domain in the configuration; otherwise, the browser will block it for security reasons. You can find more information about the okm.content.security.policy configuration parameter in the section Experimental configuration parameters
webservices.visible.properties List To make the values of the parameter “extension.external.tab.document” accessible to all users, the parameter “extension.external.tab.document” must be added to the current list.
If you forget to add the property name, only administrators will be able to retrieve the value, so some extensions may produce errors for regular users.

Create a file named test.jsp and copy it into the $TOMCAT_HOME/webapps/openkm folder.
