Creating Collaborative Whiteboard

[Charles Costa, modificado hace 14 años.]

Recently I stumbled on Liferay after receiving a request from a client who was looking for a simple solution which would allow for collaboration within his company though messages, profiles, and in particular a collaborative whiteboard which lists all users in the room and also provides chat capabilities.

After stumbling on Liferay I was amazed at the features of the suite and the seamless operation of the initial install -- which certainly saved a ton of effort in patching custom code and code from other projects. The only thing however is that I haven't been able to find a whiteboard plugin for Liferay so I wanted to see if there are any plugins created by the community which fill that void, or if I'll have to implement my own Flash or Java applet within the program.

Thanks very much in advance,

Charles

This is a 3 year old post, but are there any developments on this. I'm also very interested in this feature.

We (Rivet Logic) created a whiteboard plugin for Liferay 6.2 and it's on the MarketPlace now.

Rejoice!

That's great Alaaeldin, we've been thinking about adding some real-time capabilities to the Portal.

Would be awesome to hear your experiences with it in a blogpost form

Hi,
I have installed the whiteboard application in liferay 6.2 and wildfly 11 application server.
I added the whiteboard portlet and display it. I connect with 2 different users in 2 different PCs. When I try to write with user 1, user 2 sees nothing. I have no errors in the server log. can you help me understand where I'm wrong?

This is the log when I call the page with the whiteboard:
