how does initial-content work?
I'm trying to figure out loading initial-content from a bundle, but I'm
having a bit of trouble.
First, if I understand correctly, if I change files under my
initial-content directory and then reinstall the bundle, they *don't*
change in the repository, right?
Second, I was playing around with the espblog sample, to see if I
understand things correctly. I added the following file:
espblog/src/main/resources/initial-content/content/espblog/posts/first_post.json
that looks like this:
{
"jcr:primaryType":"nt:unstructured",
"posttext":"I'd like this post to be initial content.",
"title":"First post"
}
And when I deploy this bundle, the post is loaded where I expect:
http://localhost:8080/content/espblog/posts/first_post.html
But, this URL no longer works:
http://gandalf.local:8080/content/espblog/posts.list.html
and I believe that's because 'posts' is not a sling:Folder:
Resource dumped by HtmlRendererServlet
Resource path: /content/espblog/posts
Resource metadata: {sling.resolutionPath=/content/espblog/posts, sling.resolutionPathInfo=.list.html}
Resource type: sling:Folder
Resource super type: -
Resource properties
jcr:created: java.util.GregorianCalendar...
jcr:primaryType: sling:Folder
So, if that's not the way to load the espblog with some initial blog
posts, what is?

For some reason the espblog sample seems to require the
nt:unstructured type for the "posts" node.
I haven't checked why, but to have that node type you can add a
posts.json file to your initial content alongside the posts folder,
samples/espblog/src/main/resources/initial-content/content/espblog/posts.json:
{
"jcr:primaryType"="nt:unstructured"
}
in addition to your existing
samples/espblog/src/main/resources/initial-content/content/espblog/posts/first_post.json
This allows http://localhost:8888/content/espblog/posts.list.html to
work, but unfortunately the post is then missing the "created"
property that should be a date, and I don't think the initial content
mechanism allows for initializing date properties (unless you use
docview xml files for the initial content).
To really fix this, the espblog sample could be made to cope with
missing "created" properties, or we could improve the initial content
loader to better handle date properties.

I'm unable to reproduce your problem, but I'm thinking you may be
victim of SLING-1163 [1].
Could you check http://localhost:8080/system/console/components, and
see if any components are listed as 'unsatisfied'?
If so, restarting the bundle called 'Apache Sling Dynamic Class Loader
Support' might help.

Issue from copying. The local computer is named gandalf, so it doesn't
matter.

Just in case: The server in your first url is localhost:8080, the
second is gandalf.local:8080 ...

That shouldn't be relevant, as long as you did install the Path based
RTP bundle, which uses elements of the path (not the nt:primaryType or
sling:resourceType) to provide a resource type.
Check your web console (http://localhost:8080/system/console) for
"Apache Sling Sample Path Based Resource Type Provider". Is it there?

No, you can reloaded the content when you reinstall the bundle.
for exemple, you can add in your bundle pom.xml :
<Sling-Initial-Content>
SLING-INF/initial-content;path:=/content/myfolder;overwrite:=true;uninstall:=true
</Sling-Initial-Content>
You have other options for the initial-content.
see on the page :

Sorry, I never used this application but your content loading seems to be good.
If needed, you can also initialize the properties for the "posts" node.
Maybe, someone else can help ?
