How do I implement authentication??

[illios]

Hi,

Im noob on Errai. I have before worked with GWT as a frontend developer.

I want to try to make a todo list where users can share the list but also login and add/remove/edit the list.

Meaning I get data from a database and then restrict it with authentication.

How does this work with errai?

Is there a good example??

I would love to be able to use the messenger bus. So that the owner of the list updates his list the other users sees it!

I tried some of the demos:

mvp - user updates but you need to refreash for other users to see the change.

grocerylist - add/remove/update worked but couldnt see the changes in the other browsers.

todolist - same as grocery. I wanted to use this demo to build my app from.

all bus demos - not working.

error i get when i try to run them or clean them:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

SLF4J: Defaulting to no-operation (NOP) logger implementation

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

Implementing authentication in Errai is just like with any other Servlet-based application. You can obtain access to the HttpServletRequest from the bus architecture which can be used to enforce authentication and authorizatino like in any servlet app.

One option however is to use DeltaSpike Security if you want a non-programmatic approach.

I would be interested to hear from anyone who has got apache shiro to work with Errai.

Thanks
