[jira] Created: (SLING-990) Prototype for a Sling Explorer
implementation based on GWT
Prototype for a Sling Explorer implementation based on GWT
----------------------------------------------------------
Key: SLING-990
URL: https://issues.apache.org/jira/browse/SLING-990
Project: Sling
Issue Type: New Feature
Components: Extensions
Reporter: Christophe Lombart
Following the Sling Explorer proposal [1], I have started an implementation with the SwartGwt UI framework [2] (based on GWT and under LGPL licence).
Not sure but I think that LGPL is compatible with the Apache project.
Until now, it is just a prototype. Can you review the code and see if this Gwt application is well integrated with Sling ?

Felix Meschberger commented on SLING-990:
-----------------------------------------
I did not run the code, I just looked at the contents of the package. This lookes very interesting but misses a few things:
* We need the LICENSE and NOTICE file (and the DISCLAIMER, but this we can add on SVN commit)
* What is the licencse (and source) of the images and CSS files included ? These might have to be
attributed in the NOTICE file and *not* be (L)GPL-ed. Also a LICENSE file would be required for
them unless they are ASL licensed.
In tree-node.json.esp you do :
if (childNode == null)
{
name += child.path;
}
else
{
name += childNode.name;
//name = child.path;
}
To get the label of the resource. You might use ResourceUtil.getName(resource) here, which does the same and does not rely on the resource being a node.
children.json.esp seems to be JCR-based: How about using the Sling Resource abstractions here : listing children using ResourceResolver.listChildren and getting the propreties with Resource.adaptTo(ValueMap.class) ?

------------------------------------------
Thanks for your comments.
Yes, it is just a prototype and it is read-only :-)
I would like to get more comments before adding more features.
What's the conclusion for SmartGwt ? I can make a try with SmartGwt folks to see if it is not possible to change their license. Or maybe you ? because you have more ASF/open source experience. Your arguments will be certainly better :-)

------------------------------------------
I will modify the JSON scripts.
Ok for LICENSE, NOTICE & DISCLAIMER. I will add them if we can resolve the license issue.
The resources (images, css & js) are under LGPL. I took those files from Smart GWT 1.1 distribution. Maybe we can use others.
If LGPL is an issue, we cannot continue to use SmartGwt because the current implementention requires 2 SmartGWT jars (see the pom.xml). Those jars are also under LGPL. There are used to run the application in the hosted mode and compile de java code into js.

Bertrand Delacretaz commented on SLING-990:
-------------------------------------------
I had a quick look and this looks good.
To build it, I had to set the maven-sling-plugin <version> to 2.0.4-incubator in pom.xml
Also, I think the URL used to access the explorer ( /explorer/index.html ) is not mentioned in the README.
Is it correct that this version is read-only? That's not a problem, I'm just not sure if I haven't found how to edit stuff ;-)

-------------------------------------------------
Congrats Christophe, looks good!.
Regarding SmartGwt, I´d prefer to keep more simple with just GWT :).

------------------------------------------
SmartGwt provides more advanced widgets. That's the main reason why I started the explorer with it.
We can use GWT but it will take more time to provide a nice UI.
SmartGWT is already based on a dual license (LGPL & commercial).
I can refactor the project to use only GWT

Cool, so we get a Resource tree explorer !
> The resources (images, css & js) are under LGPL. I took those files from Smart GWT 1.1 distribution. Maybe we can use others.
Could these be extracted from the artifact downloaded from the maven repository on build time ? So that we don't have to store this in our SVN.

Would it be a big problem to not be able to use SmartGWT ?

Hi all,

I think, this primarily means we are not allowed to distribute the final
bundle build as a JAR file containing the (L)GPL licensed stuff.
IIRC we are allowed to have the source in the SVN repo provided it only
contains properly licensed files and we probably should make sure that
anyone using this is aware of using (L)GPL licensed when building and
running.
Maybe Jukka may add to this ?
Regards
Felix
