Description

I am evaluating sling.

I succeed in setting it up and it works as I thought, seems to be a very valuable product for those who want to rapidlly build a software that relies on JCR, which is my case.

But the next question is "Should I use a noSQL Database or not". As it may be an important choice, since Sling is not really compatible with SQL database, I wanted to make sling run with MongoDB.

I read the documentation, and at first impression, it seemed quite immediate; I simply have to add an option to change the mode of launching the starter application, as it is said in the following documentation: https://sling.apache.org/documentation/the-sling-engine/the-sling-launchpad.html

 

So I tried to launch the starter application with the following lines:

java -Dsling.run.modes=oak,oak_mongo -jar org.apache.sling.starter-10-SNAPSHOT.jar

and checked with a mongodb client if a mongodb server was started or not ...

As I was unable to connect to mongodb://localhost:27017 I guess something is missing, maybe mongodb should be installed separetely ? 

 

I continue reading the documentation, and find https://sling.apache.org/documentation/bundles/nosql-resource-providers.html

OK, my conclusion was I missed to install the nosql-resource-providers, so I installed the bundle and check again ...

Nothing new, it seems I have done nothing.

So, always according to https://sling.apache.org/documentation/bundles/nosql-resource-providers.html, there is another launchpad to use.

There is the link to the source code: https://github.com/apache/sling-old-svn-mirror/tree/trunk/contrib/nosql/launchpad

But it is said that this source repository is obsolete and shall not be used.

So I get back to apache git repository, and filtered on "sling" and "nosql", I can find some code now ...

https://github.com/apache?utf8=%E2%9C%93&q=sling+nosql&type=&language=

But it is absolutely not clear to me whether I have to do something with that modules or not ...

So my real problem is I can't get the right documentation on "How to setup Sling 9 to work with mongodb" and there is, as far as I know, no forum where I can ask this to a community to help.

I guess sling is working well with mongoDB, but if I need 10 days to set it up (I spend 1 day, maybe it is not enough) my point of view is made: I won't use mongodb.

But this maybe a terrible mistake !

 

So help please !
