Cannot resolve reference to bean 'rhinoScriptDebugger' - how to enable server-side JavaScript debugger?

[anon26949]

I have Alfresco Community v5.2.0 and Alfresco Share v5.2.c that running on Apache Tomcat 7.0 Servlet/JSP Container, installed on CentOS 7.3.

As far as I know, I can use two approach to enable the JavaScript debugging:

1. Enable the debugger for every time when server starts
2. Enable the debugger when required.

If I use first approach.

For the repository tier I set the following property in /tomcat/webapps/alfresco/WEB-INF/classes/log4j.properties:

...
log4j.logger.org.alfresco.repo.web.scripts.AlfrescoRhinoScriptDebugger=on
...‍‍‍

For the web tier I set the following property in /tomcat/webapps/share/WEB-INF/classes/log4j.properties:

...
log4j.logger.org.alfresco.web.scripts.AlfrescoScriptDebugger=on
...‍‍‍

As a result, I get an exception.

For the repository tier, I go through the link http://localhost:8080/alfresco/service/api/javascript/debugger then I see the following:

I press Enable and get exception again:

What I'm doing wrong? How to enable server-side JavaScript debugger?

I would be very grateful for the information.

Thanks to all.

[afaust · Accepted solution]

You are trying to start the debugger in a headless environment. The debugger needs a screen attached to the process running the Tomcat instance. Typically a server will not have that and as a result you cannot use the debugger.

Axel is correct but you might be able to get something to work if you use X11 forwarding (ssh -X) - I haven't tried in a while but this old blog post gives some pointers Alfresco debugger in a VirtualBox VM – Thoughts about technical things
