Re: How to Execute a Sling Replication

[Andreas Schaefer Sr.]

Hi Timothee

I am slowly getting there. As much as I love OSGi for its extensibility as much
I hate it when it goes wrong.

Turns out for the Forward Distribution Agent I need a Distribution Package 
Builder
which is not configured in the Sample but I could also not find it in the IT 
tests.

After having a closer at the IT tests I figured out that I also need to set the
run mode ‘notshared’.

This did the trick and now I have the author configuration up and running.

I let you know if I run into other issues.

Thanks - Andy

Re: How to Execute a Sling Replication

[Andreas Schaefer Sr.]

Hi Timothee

Thanks for the quick reply. If you are referring to:

curl -v -u admin:admin 
http://localhost:8080/libs/sling/distribution/services/agents/publish -d 
'action=ADD' -d 'path=/content/sample1’

then it does not work on my installation. I get a ‘Unsupported Operation 
Exception: create’ which
I think happens because the call to the agent is ignored. One thing I noticed 
is that this node
in Composum is never resolved (spinner keeps on spinning).

With the investigation into the Default Distribution Component Provider is will 
also check out
this as I think they are related.

How to Execute a Sling Replication

[Andreas Schaefer Sr.]

Hi

I managed to build and install the Sling Distribution including
the sample package. Everything looks fine but I am not sure
how to start a replication of a given node.

I want to replicate a given node on the Author to the Publish
instance(s) defined in the used agent. How would I do that
from the command line?

Re: Service user for sling pipes

[Andreas Schaefer Sr.]

I use a Service User and packaged it up in a Content Package which deploys just 
fine.

The only drawback is that if you need to set permissions with it then you might 
end up
with an issue where the user is created after the policies are created which 
leads to
the policies not being set (no user there).

I think the best solution is to provide a package that contains the service 
user and
service user mapping and ask the deploy to install it first.

To create the service user package I just created the Service User manually with
Composum, created a package, downloaded and integrated into my project.

Re: Securing a Servlet w/o Resource

[Andreas Schaefer Sr.]

Yeah, that might be a good idea.

That said I ran into an issue with JCR Package and Groups.

Having a group part of the package will replace the group
node during installation even when filter mode is set to update
or merge.

This is an issue because User Group Membership is stored on
the group and a redeployment will wipe that.

Is that by design?

Securing a Servlet w/o Resource

[Andreas Schaefer Sr.]

Hi

If I have a servlet that is not based on a resource how would
I secure access in Sling?

This is what I came up with on doPost():

userManager = AccessControlUtil.getUserManager(session);
Authorizable authorizable = 
userManager.getAuthorizable(request.getUserPrincipal());
if(authorizable == null) {
// handle anonymous user
return;
}
boolean ok = false;
if("admin".equals(authorizable.getID())) {
ok = true;
} else {
Iterator i = authorizable.declaredMemberOf();
while(i.hasNext()) {
Group group = i.next();
if("sling-node".equals(group.getID())) {
ok = true;
break;
}
}
}
if(!ok) {
// Handle wrong permissions
return;
}

 In addition to what others have said, there is plan ( with no
 time
 commitment ) to add our own content-package Maven plugin, which
 would
 make this kind of project usable with Maven.

Re: Different ways to define initial content :: Content.xml vs Json equivalent

[Andreas Schaefer Sr.]

Hi Greg

One difference between an JCR Content Package (ZIP file) is that you can use
the exploded tree inside the Eclipse or IntelliJ plugin and edit / deploy / 
import (from
server) one file at a time. With the Bundle Content you have to deploy it
as an entire bundle.

If working with JSon you have to keep in mind that:

1) You don’t have comments but you can add a comment attribute but
see that as JCR property

2) There is only a SINGLE LINE text in JSon

This works:

“attributeOne” : “One line is ok”

This does not:

“attributeTwo” : “This line will
  fail as it is multi line”

For most part this is ok but certain configurations that is not good.

Having worked on bigger AEM projects we ended up having many
JCR Content Packages and OSGi Bundles and so eventually we
used a dedicated ALL JCR Package which is just there to bundle up
all artifacts and deploy them in one swoop.

For most part I prefer the Bundle Contents over JCR Packages especially
with Sling as Composum prints outs node properties as JSon. That said
I never worked on a big project with it and so I don’t know what issues
I would face. A friend of mine said they ran into issues with it.

As far as I know SLING-INF is not needed but I would recommend to
place your content is a specially marked folder and not just 
/scr/main/resources.

This line is more instructive:


SLING-INF/libs/sling/validation/i18n;overwrite:=true;path:=/libs/sling/validation/i18n

than this:

apps/fling;path:=/apps/fling;overwrite:=true;uninstall:=true

In Sling 9 you can have both JCR Packages and Bundle Content w/o any issues.

Re: Fling Installation on Trunk

[Andreas Schaefer Sr.]

For something else I delved into Sling Provisioning and I
came up with a way to import Thymeleaf. Not sure if  that
is the best way but it seems to work.

When I add a file called thymeleaf.txt to 
launchpad/builder/src/main/provisioning
with that content:

[feature name=thymeleaf]

# Add the dependencies on the Model exporter
[artifacts]
org.attoparser/attoparser/2.0.2.RELEASE
org.unbescape/unbescape/1.1.4.RELEASE
org.apache.servicemix.bundles/org.apache.servicemix.bundles.ognl/3.2_1
org.javassist/javassist/3.20.0-GA
org.apache.sling/org.apache.sling.scripting.thymeleaf/1.1.1-SNAPSHOT

Build and start sling (just the builder) I have thymeleaf installed and prepped
and ready.

So I am wondering if there is a better way or if I can create my own 
provisioning
models but keep them in a separate folder.

Re: Use of global HTL object log

[Andreas Schaefer Sr.]

Hi Burkhard

Thanks for the tip. After tinkering around with REPL I finally got it working 
with
this,

The page logging:

${logError.logMe}

The logic.js containing the method:

use(function () {
var text = this.text || ' Not Found';
return {
logMe: function() {
log.error(text);
}
};
});

Here with a single parameter:

${logError.logMe}

use(function () {
var text = this.text || ' Not Found';
var param1 = this.parameter1;
return {
message: 'hello world',
logMe: function() {
log.error(text, param1);
}
};
});

Not quite user-friendly but it gets the job done.

Hi

In the HTL documentation I saw that there is a global
HTL object log for the SLF4J logger.

How would I use that logger?

Re: Fling Installation on Trunk

[Andreas Schaefer Sr.]

Hi Oliver

It would be nice if the Readme would indicate that this is a work in
progress to avoid users wasting time on a piece that is not ready
for prime time. As the trunk is probably the first thing people
get as Sling code this would be helpful I think.

In my opinion an example should be plug and play. For anyone
not very familiar with Sling this is disheartening and can turn them
away from Sling. I hope that Fling eventually gets there but for
now I pass as I don’t have the time to look into that (have my own
little peeve Sling project).

Re: Sling Resource Rendering Inheritance

[Andreas Schaefer Sr.]

Hi Roy

Thanks for all your help.

At the end it turns out that I made a mistake when using the HTL include:

This was my first include:



which fails. But using this:



does work.

So on another node I saw some Sling apps (samples and Composum) that place
their components under /libs instead of /apps.

In AEM developers were told not to put anything under /libs and now Sling it 
going
the other way. Is there a reason for this shift. As far as I know there’s no 
difference.

Thanks for all your help - Andy

Re: Sling Resource Rendering Inheritance

[Andreas Schaefer Sr.]

Yeah, the have a big “Download Now” button and that is not the file.
I think the reason was that I use Safari w/o Flash and then the link won’t show.

That said your code words and the major difference I saw is that the inheritance
only works if it is in the /apps//components folder. I 
tried
that after I got mine working by copying the working resource type definitions 
back
up to /apps/.

This structure works:

/apps
/testApps
/components
/home
body.html
/page
body.html
page.html

The page.html has a HTL import of body.html and it will take the one from actual
resource type (here testApps/components/home).

Can anyone from the sling team verify that? If so why, where is that defined and
is that configurable?

I used the sling sample Fling as an example but that does not use inheritance.

Thanks for you swift help - Andy Schaefer

Sling Resource Rendering Inheritance

[Andreas Schaefer Sr.]

Hi

As a long time CQ / AEM backend developer I ran into some issues
to adjust to Sling.

I have a resource ‘Home Page’ that should render a JCR node as
a HTML page. The Home page component then only adjust
the layout of the Body and Head and the rest should be inherited from
its Resource Super Type “Page’. I tried that but it does not render
without the home.html as well as the footer missing in Home is not
picked up.

This is my configuration:

1. JCR Content Node (/content/sample/home)


http://www.jcp.org/jcr/1.0 " 
xmlns:nt="http://www.jcp.org/jcr/nt/1.0 " 
xmlns:sling="http://sling.apache.org/jcr/sling/1.0 
"
 jcr:primaryType="nt:unstructured"
 jcr:title="Sample Home"
 jcr:description="Sample Home Page"
 sling:resourceType="sample/home"
 sling:resourceSuperType="sample"
/>

2. Home Page configuration (/apps/sample/home):


http://www.jcp.org/jcr/1.0 " 
xmlns:nt="http://www.jcp.org/jcr/nt/1.0 " 
xmlns:sling="http://sling.apache.org/jcr/sling/1.0 
"
 jcr:primaryType="sling:Folder"
 jcr:title="Sample Home Page Component"
 jcr:description="Sample Home Page Component woth HTL"
 sling:resourceSuperType="sample/page"
/>

This only contains the head.html and body.html file.

3. Page Configuration (/apps/sample/page):


http://www.jcp.org/jcr/1.0 " 
xmlns:nt="http://www.jcp.org/jcr/nt/1.0 " 
xmlns:sling="http://sling.apache.org/jcr/sling/1.0 
"
 jcr:primaryType="sling:Folder"
 jcr:title="Sample Page Component"
 jcr:description="Sample Page Component"
/>

This contains the page.html which includes the head, body and footer.html file.

This setup does not work and I could only make it work by providing the 
/apps/sample/home/home.html.

Any way to make the work like in AEM?

I am pretty sure that I don’t see the forest because of the trees here
but I could not figure out how to do it right even when looking at the
Sling Samples.

Re: How to create Rest APIs for non-JCR data in Sling 8??

[Andreas Schaefer Sr.]

I never develop for Sling but a few years doing backend on AEM.

So I am wondering if you used the Sling IDE Tooling (Eclipse or our IntelliJ 
Plugin)
and debugged your code there.

Did you try to use a Servlet that is bound to a Type instead of a Path? This
might do what you want.

Cheers - Andy

Re: Multiple Version of Commons Lang in OSGI...

[Andreas Schaefer Sr.]

I use Commons tools both version 2 and 3 together in AEM and so it should work.

That said how are you installing Commons lang and which package does need it.

If you have a custom package that needs commons lang 3 then you need to package 
it with it
if it is not provided from another package.

This is all OSGi behavior but this should be resolvable within.

Dynamic Resource Change Listener

[Andreas Schaefer Sr.]

Hi

I would like to listen to JCR Nodes being added, modified and removed in Sling 
and saw that you provide the Resource Change Listener which would work 
perfectly but I could not figure out how to make the paths to listen for 
dynamic.

What I would love to have is to configure an OSGi Service that either 
implements ResourceChangeListener or does register one with Sling. The paths to 
listen for are set by the OSGi Configuration and the user can add, change or 
remove paths.

Is there a way to create a Resource Change Listener(s) dynamically so that when 
I receive the configuration (changes) I can register them rather when the 
Resource Change Listener service is deployed?

Thanks - Andy Schaefer
