[jira] Created: (SLING-989) scripts in /apps are read by user session, this leads to security problem
scripts in /apps are read by user session, this leads to security problem - Key: SLING-989 URL: https://issues.apache.org/jira/browse/SLING-989 Project: Sling Issue Type: Bug Reporter: Michael Marth At the moment the user session is used to read the scripts stored in /apps. Most web apps have some anonymous users as well, therefore the ACLs of /apps must allow read access of the /apps directory. Hence, all scripts within /apps are readable by anyone. I suggest to allow the Sling administrator to configure which session to use when the scripts are read. He could choose the admin session or stick with the default (the user's session). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
Re: (In)Security in Sling
Hi, thanks John, for pointing this out. Part of the problem you describe is misconfigurations on my part (I did not realize that the anonymous user is not part of the everyone group). But as Felix has described the problem with the /apps directory cannot be fixed by configuration. I just filed bug 989 [1] for this (an in-the-air collision with Felix' mail). As a third aspect: I believe there are parts in most sites where the json representation is not desired. What do you think about making the json servlet more configurable in terms of black/whitelisting properties it renders? That would be on top of all other proper security measures, of course.

One thing that I have been increasingly concerned with is the end users ability to scrape all of the sites content and code with minimal effort using the built in functionality of the SlingPostServlet. The Sling Get Servlet to be precise ;-) For Example: http://dev.day.com/discussion-groups/users.infinity.json http://dev.day.com/discussion-groups/apps.infinity.json As Jukka said, you may employ access control to prevent this. But there is a glitch for the scripts located in /apps and /libs: Currently scripts are read from the repository using the session of the current user, that is the request user. So preventing access to http://dev.day.com/discussion-groups/apps/mailingLists/mailingLists.jsp by simply denying read-access for the anonymous user actually prevents using the site at all. One solution to this problem could be to not load the scripts with the session of the current user but to use a special-purpose session (for example an admin session) to do this. This way, you may lock down /apps and /libs for general consumption but may still execute the scripts in there. WDYT ? Regards Felix (this one really disturbs me) So far, my solution has been to provide a proxy (namely Apache2) in front of sling to filter out any undesired requests. Seems to work. But, by doing this, it takes way what is so cool about Sling. I have reported to Day Support numerous times, but they don't seem too concerned about it. But for sites where the content is critical or where we require users to pay for our content, it is very important to us. Is there a better way to handle this? Please let me know your thoughts.

Re: Integrate Sling with data from another system
Hi, [I believe that large parts of your question are of interest for the Sling group, so I'll answer here. For the parts that are related to Communique only you might want to head over to http://groups.google.com/group/day-communique] As far as I understand it you try do to the import in a way that is possible, but not very JCR-like: As the data is not stored in JCR repository as nodes, but a plain file I would recommend to actually store each of your products in a JCR node at a path like /mobile/handset/NokiaN75 or /content/mobile/handset/NokiaN75 Like that the script resolution is handled by Sling and you will not need the 20+ controllers. The import itself could be done with a little standalone JCR app. IIRC Sling can also process POSTed XML files (and produce nodes) so if you can control the incoming XML format that might be even simpler (but I would personally go the first route) hth Michael On Sun, Mar 15, 2009 at 7:21 AM, tao wen tao...@gmail.com wrote: Integrate Sling with data from another system We are working a public website using CQ 5. Some of the data like product catalogue comes from another system. The requirement asks us to get the data and embed them as part of the page hosted by CQ. This is a challenging job to us, as we can not find any example out there doing this. The challenges we have identified are: 1. How to get/load the data 2. How the data being updated and notified 3. How the data being rendered 4. How to embed them as part of the page Before we sending out this mail to ask for help, we did some consulting with sales of CQ, and did some homework like reading source code of sling. Here are our planned apporaches. We need some advices here about are those apporaches following the best practices of sling or simply anti-patterns. 1. How to get/load the data Some background: we will deploy three CQ instances. One author instance and two publish instances. The data will be prepared in author instance using JDBC, and doing some transformation in memory. The result will be persisted into a xml file and saved in JCR repository. We rely on replication functionality to publish the xml file to the publish instance. Then in the publish instance we just need to read things in xml back into memory. 2. How the data being updated and notified We will set up a scheduler in author instance to poll the data every day. The update will be notified as event. If the replication process can generate event itself, then we will rely on it. Otherwise, we need to set up new topic and publish event to it when the serialized xml file being updated. We assume CQ will distribute the event to publish instance so that the publish instance can know they need to refresh the data in memory using the updated xml file. 3. How the data being rendered As the data is not stored in JCR repository as nodes, but a plain file, so things like /mobile/handset/NokiaN75 can not be understand by CQ. To make those nodes available, we write our own resource provider, and map it to /mobile/handset. We will do URL parsing ourself to get the parameters. The final resource provided to script engine will contain the necessary data. In the page, we can reference the handset by reference the current node (a.k.a the resource provided). The resource provider is similar to tranditional controller in MVC architecture. So there might be 20+ controllers in a system, would that be a issue? 4. How to embed them as part of the page We leverage the CQ component here. The component will be configured with a URL, where it can fetch its html. So, the comonent can not render itself, instead, it relies on another URL to do it (which is backened by a controller). To do this, we either need to implement some sort of server side include, or using client side ajax call. The concern of server side include is how to do that, and how to pass user session. The concern of using client side ajax call is the user experience might be impacted as the network could be slow. We were told from the sales of CQ that to be effective about page caching, we’d better to use ajax call to retrieve the dynamic content. Any comments? -- Michael Marth | http://dev.day.com/

json query servlet and excerpt path
Hi,
I tried to make sense of the re:excerpt feature in the json query servlet
and hit the same problem as in [1]
After a fresh Sling install this query
http://localhost:/content.query.json?queryType=xpathstatement=//*[jcr:contains(jcr:content,'sling')]/rep:excerpt(
.)
gives the correct but slightly useless result
[{name:index.html,jcr:path:/index.html,rep:excerpt():excerptfragment\/fragment\/excerpt,jcr:score:1000},{name:sling-test.html,jcr:path:/sling-test/sling/sling-test.html,rep:excerpt():excerptfragment\/fragment\/excerpt,jcr:score:904}]
(i.e. the excerpts are correct, but it is desirable to get the excepts of
the jcr:content node below)
However, adding an excerptPath like:
http://localhost:/content.query.json?queryType=xpathstatement=//*[jcr:contains(jcr:content,'sling')]/rep:excerpt(.)excerptPath=jcr:content
gives:
[{name:index.html,jcr:path:/index.html,rep:excerpt():,jcr:score:1000},{name:sling-test.html,jcr:path:/sling-test/sling/sling-test.html,rep:excerpt():,jcr:score:904}]
(i.e. no excerpts at all).
Is this a user error on my part or a bug?
A second issue I have: without excerpts I get the jcr:primaryType in the
results, but I do not get this property when the query contains an excerpt.
i.e.
http://localhost:/content.query.json?queryType=xpathstatement=//*[jcr:contains(jcr:content,'sling')]
yields
[{name:index.html,jcr:path:/index.html,jcr:score:1000,jcr:primaryType:nt:file},{name:sling-test.html,jcr:path:/sling-test/sling/sling-test.html,jcr:score:904,jcr:primaryType:nt:file}]
Shouldn't the primaryType be present even with the excerpt?
Thanks for having a look
best regards

Re: SlingPostServlet: How to handle resource paths when creating content (Re: [jira] Commented: (SLING-588) Sling ignores specified node path when creating content)
Hi Felix, Lars, thanks for the help. I will give it a try. Yet, I still wonder why we chose to ignore selectors and extensions on POSTs. It appears inconsistent to me that we have these mechanisms that work beautifully for GET requests, but on POSTs they don't. Actually, before looking into the docu and asking here I spent quite some time just trying to POST to a script with a selector because I naturally assumed that this would work. Maybe there is a good reason why POSTs with selectors are a bad idea, but otherwise I suggest to re-consider them. WDYT? Michael You can help yourself with a servlet which you write for your blog post resource type handling POST requests. In addition your servlet would implement the OptingServlet interface, which has the accepts(SlingHttpServletRequest) method. In this method you check whether the POST request is a Trackback request or not. If the request is a simple update POST, just return false and your servlet will be ignored. If the POST request is a Trackback request, return true and your servlet will be called to handle the POST request and the default SlingPostServlet will not be called. -- Michael Marth | Day JCR Cup 08 | Win a MacBook Pro: http://dev.day.com/

Re: SlingPostServlet: How to handle resource paths when creating content (Re: [jira] Commented: (SLING-588) Sling ignores specified node path when creating content)
Hi Felix, I have a question about that: URL for the selection of the concrete representation (script). For other requests (POST, DELETE, ...) you want to modify the resource (and don't care for the representation) and hence _should_ address the resource directly without any representational detail such as selectors and extensions. I would like to implement two different POST features on one node. As always, a blog example :) The nodes are blog posts, one feature is posting reader comments, the second feature is trackbacks (which come along as POST requests from other blogs). For the comments I am OK with the default behavior (I do not want to overwrite POST.esp). For the trackback feature I need to implement a custom behavior (as specified or rather agreed upon by the different blog systems). How could I construct a URL that would make it possible to distinguish the two POSTs if there are no selectors? Related to this: trackback POSTs are supposed to return an xml document containing success or error messages. So in my understanding of Sling's handling of extensions for GET requests the URL for trackback POSTs should end in .xml. You might say that there is no problem, because Sling ignores the extension anyway, so it might as well be .xml, but it seems a bit inconsistent to me. I think a POST to /foo.xml should return xml and a POST to /foo.html should return html Cheers Michael -- Michael Marth | Day JCR Cup 08 | Win a MacBook Pro: http://dev.day.com/

Re: [RT] Post processing of POSTs
Hi Carsten, sorry, I was not very specific about scripting, indeed. IIUC one needs to supply an OSGi bundle in order to be able to tweak the POST behavior. What I would like to do is adjust the POST behavior without having to resort to deploying an OSGi bundle i.e. directly from a JSP. For example, if one could write a POST.jsp that executes the default behavior and passes back the change list (additionally to the mechanism proposed by you): % changes = Sling.defaultPOSTBehaviour(); // do some more % (this code is an illustration of what I mean rather than an actual suggestion) The use cases in the back of my mind are a) adding mixins to newly created nodes and b) comment spam prevention on a blog.

Re: [RT] Post processing of POSTs
hi, i like bertrand's proposal to make available the post servlet's methods in scripts. that way we would not need to add additional script name resolution logic. script authors could do whatever they want , but would not have to reimplement existing functionality. i also have 2 use cases for this at hand: a) adding mixins to newly created nodes and b) creating new node versions (in the jcr sense) when changing existing nodes.

While the pre processing can modify this list of changes, the post processing can only do additional things. I don't think that the list of actions is known upfront. Because this list is built as the actions re executed. (Right now). Yes, I know - but I think it could be possible to first generate the list of changes and then apply them.

Re: Standard Sling Project Template

comment on addressing the binary property jcr:data of an nt:file
Hi, I am fiddling around with nt:file and Sling and came across something which seems to be a bit inconsistent or maybe a bug. In the browser I can access the (binary) jcr:data property of an nt:file directly, like: http://myserver/path_to_ntfile/content/jcr%3acontent This returns the content of the file. But if I try to include the file contents through sling.include I get a resource not found in the log ( o.a.s.j.r.i.JcrResourceResolver: Could not resolve URL xxx to a Resource). That's OK, because it is not a node, but a property. However, I can access it in the browser, so it struck me as a bit inconsistent. Related to this: a while ago we had a discussion if there is a use case for addressing properties in urls (rather than just nodes). I think at that time there was no use case found. Well, addressing jcr:data is a use case for me at least. (if this behaviour is really a bug let me know, I'll file it) Cheers Michael -- Michael Marth, http://dev.day.com

Re: comment on addressing the binary property jcr:data of an nt:file
Hi Felix, I am not sure, whether I can help you, because you just say, you try to include ... through sling.include without telling which path you use to include. This should of course work, except if you mangle with the path. So if you use /path_to_ntfile/content/jcr%3acontent as the resource path it is expected to get an error. You would actually have to included path_to_ntfile/content/jcr:content You are right. I had unescaped the colon, but there was actually another url-escaped character in the path.

Michael Marth commented on SLING-282:

this might be related (regarding collections handling):
the property to is multivalued.
in the script I do something like:
%= currentNode[to][0] %
if the value of to has only one value I seem to get back this value as one
string so [0] gives me the first character. if to has 2 values I get back a
collection so [0] gives me the first element. this is consistent with what
[to].length gives me.
I am not 100% sure if this is a bug (might be my lack of understanding for
javascript), if so a comment on how to determine the result length of a
multi-valued property would be appreciated.

Re: various questions regarding alternative scripting engines
Hi Felix, But if I try to access something like $resource.node (which I would have expected) Velocity does not recognize the expression. How do I get to the node? Do I have the wrong syntax? I looked at the src of JcrNodeResource and expected to be able to use something like .node, .getNode() or similar. I do not exactly know, how velocity maps Java objects. But a resource is definitely a Resource and by conincidence a JcrNodeResource. In addition, the JcrNodeResource.getNode() method is not public and not part of the API. When you want to access the node of a resource you will have to adapt the Resource to the Node class, something like: $resource.adaptTo(Node.class); But I am not exactly sure about the exact syntax. I am not exactly a velocity expert, but I tried this and had no success so far. But I also think that having to cast (sort of) a resource into a node in a script is a bit weird. Especially, if you consider that resource.nodeworks in esp's. Could we not just get the node as an object right away? I am aware that this has been discussed before, but I do not see any advantages of abstraction lost if the node object is available to the scripts if the resource in question is actually a node. The script needs to know it handles nodes anyway. WDYT? Michael
help, my content model looks un-Slingable
Hi, I have an existing content model and want to build a sling app on top. The model is Jukka Zitting's mail model he coded for James (see [1]). One mail is stored as: nt:file |-jcr:content (unstructured) |- from (string) |- to (string) |- jcr:data (binary) ... In order to display a mail via Sling I added a property sling:resourceType to the jcr:content sub node (because I could not add it to nt:file). My URL now looks something like: http://localhost:/content/.../emailtitle/jcr:content or http://localhost:/content/.../emailtitle but in both cases the binary jcr:data is returned directly. Do I have to change my content model or do you guys see a way that I can access my mail resources and have a script being executed? Thanks for hints Cheers Michael [1] http://dev.day.com/microsling/content/blogs/main/jcrmail.html -- Michael Marth, http://dev.day.com
Re: help, my content model looks un-Slingable
Hi Felix, thanks a lot - I'll give it a try. Maybe it would be helpful if we had some additional script resolution based on URLs or paths. In my example I could map a script to nt:resource if the resource is below /content/mails or so. Such a mechanism could really be helpful for users that have no possibility to modify existing content. Cheers Michael On 2/15/08, Felix Meschberger [EMAIL PROTECTED] wrote: Hi Michael, I just updated the jcr/resource module to create a sling:Resource mixin node type, which defines a sling:resourceType property as a String. You may attach this mixin node type to your mail node and set resource type accordingly. This gives you the full flexibility to render your mail specifically. Alternatively, of course, you may create a servlet or script for the nt:file resource type. But this has the advantage that all nt:file nodes regardless of whether they are actually mail or not will be rendered by that servlet or script. The first option is probably better.

Re: various questions regarding alternative scripting engines
Hi Felix, when I use var node = resource.adaptTo(Packages.javax.jcr.Node) I get an exception Cannot find function adaptTo. (I guess this is a temporary problem. Or does it work for you?) Which is probably an error as it introduces an API in JavaScript which is not paralelled by the other APIs, we should probably remove that Rather than removing the very useful resource.node from esps for consistency reasons I would kindly ask to introduce resource.node into other scripting engines as well (would be consistent again :) ). I believe that this can be done by injecting a node object within the scripting engine implementation so that the Resource interface does not have to be changed again. I think that this would be really helpful for Sling adoption because it would make things easier for newbies. Cheers Michael -- Michael Marth, http://dev.day.com

various questions regarding alternative scripting engines
Hi,
I am just looking at the various scripting engines and ran into some probs.
Maybe someone can help?
Velocity
---
I have installed the velocity bundle and want to do the first test in
Bertrand's 15min tutorial with a velocity script. Saving this as
html.vltworks OK:
html
body
$resource.getResourceType() br
$resource.getPath()
/body
/html
I get something like:
foo/bar
/content/mynode
But if I try to access something like $resource.node (which I would have
expected) Velocity does not recognize the expression. How do I get to the
node? Do I have the wrong syntax? I looked at the src of JcrNodeResource and
expected to be able to use something like .node, .getNode() or similar.
Freemarker
Almost the same as velocity. If I save this as html.ftl
htmlbody
${resource.resourceType} br
${resource.path}
/body/html
This works, but this
htmlbody
${resource.node}
/body/html
Gives an exception: Expression resource.node is undefined on line 3, column
3 in /apps/foo/bar/html.ftl. The problematic instruction: -- == ${
resource.node} [on line 3, column 1 in /apps/foo/bar/html.ftl] --
Java backtrace for programmers: --
freemarker.core.InvalidReferenceException: Expression resource.node is
undefined on line 3, column 3 in /apps/foo/bar/html.ftl
Ruby
---
Saving anything as html.erb gives me an exception when I do a request like
above. I installed the scripting bundle just like for velocity and
freemarker. The console says things are fine. The exception is:
org/jruby/runtime/callback/InvocationCallback (500)
The requested URL /content/mynode.html resulted in an error in Sling Default
Error Handler Servlet.
Exception:
java.lang.NoClassDefFoundError:
org/jruby/runtime/callback/InvocationCallback
Is there additional installation work to be done for Ruby?
Thanks a lot for hints

As the Sling modules start asynchronously, what might happen is that
they're not ready yet. But startup shouldn't take more than a few
seconds on a decent system.
If retrying doesn't help, have a look at the log created under
launchpad-webapp/target/logs/error.log, and if any errors are
reported. I've just added the info about that log file to the wiki

Re: Filter Scripting (was: POSTs and microjax)
Alex, I can understand both sides of the discussion because both are needed. It just depends on the user's or customer's requirements. I agree. Maybe it'd be good if we treated scripting and Java development as equal citizens, i.e. if we tried to make available all features to both approaches if that is possible (I am not sure if it is, though). Cheers Michael -- Michael Marth, http://dev.day.com
Re: µsling 2.0 requirements (was: [RT] Shall we merge microsling into Sling?)
Sounds great. This WebDAV module currently supports the Jackrabbit JCR repository, but Sling is meant to run with any JCR repository. OK, but can I add: switching the repository to another JCR repository is comparatively easy (i.e. does not require a recompile) (I like CRX's Repository Explorer) -- Michael Marth, http://dev.day.com
Re: Error Handling in Sling
Guys, you might have lost me in this discussion, but may I ask anyway: We now have three orthogonal pieces in resolving a script: http method, requested mime type and response status code (plus script language). How do they get mixed in the script resolution process? Which script will be executed when there is a request for a *.pdf that results in a 404? Is it 404.pdf.esp or 404.esp or sthg else? thanks for clarifying Michael On 12/20/07, Felix Meschberger [EMAIL PROTECTED] wrote: Hi, Am Dienstag, den 18.12.2007, 17:44 -0800 schrieb Padraic Hannon: +1 From what I understand of your proposal this sounds great.

First, though, I present the current implementation. Current implementation -- Currently Sling (the core project) defines a ErrorHandlerServlet. This interface may be implemented by error handlers and registered as OSGi services just like any plain Servlet. In case of an error (HttpServletResponse.sendError or an uncaught Throwable), Sling core kicks in an error handler which calls the canHandle method of each registered servlet in turn. For an error with status code a series of status values is checked against the servlets until a servlet can handle. The series is defined as ( sc, (sc/10)*10, (sc/100)*100, 0 ) e.g. for the status 413 the series would be ( 413, 410, 400, 0 ). Sling core contains a default error handler servlet which replies true for the last entry (0). For an exception to be handled the class hierarchy of the exception is checked. For a FileNotFoundException, the classes FileNotFoundException, IOException, Exception, and Throwable are checked. The Sling core default error handler replies true for the Throwable class. Proposal This implementation is working but it is rather limited as all 404 stati are handled by the same handler regardless of the actual request. Starting from the proposal on the dev list, we could resolve the error handler servlet or script just like any request handling servlet or script. The error handler creates a temporary SlingHttpServletRequest wrapper whose getMethod() implementation returns the status code or Throwable thrown. With this wrapper object the same resolution process takes place as for a normal HTTP method. If no servlet or script can be resolved the default error handler is used (instead of the normal default servlet). The call to the error handler script or servlet is done using the unwrapped SlingHttpServletRequest, that is the getMethod returns actual request method. Also the usual request attributes are set as defined in the Servlet Specification. A handler for a status code is only searched for the exact status code. A handler for a Throwable is still searched through the class hierarchy, which is line with catch clauses, which also support the class hierarchy. WDYT ?

POSTs and microjax
Hi, this has been discussed before, but without conclusion afaik, so I would like to start this discussion again: at the moment one can only use the microjax post servlet in an all-or-nothing way. This means that my app needs to decide: I either send POSTs to the microjax servlet and that's all there is. Or I implement POST.esp which means I can do all I wish to do, but I have to replicate all of microjax's servlet functionality (in terms of writing to the repository). I would really like to have a mechanism to mix this, i.e. to extend the microjax servlet with custom logic. And there is actually a real-world use case for it: Spam filtering. Right now I had to revert to a Java servlet to do this (because I did not want to implement POST.esp). IMO it would be great if we had something like filters or pipelines or whatever you want to call it in microsling. WDYT? Cheers Michael -- Michael Marth, http://dev.day.com
Re: use case: resolving a resource based on a node´s version
Do people think we need a syntax for selectors that are handled by the Sling/microsling framework and not by applications? Yes.

Re: Request Data Validation
Hi David, re the use case I still got this one I brought up a while ago: catching spam comments on a blog. However, for this use case I do not think I need the validator functionality typically offered in web frameworks (like checking for empty strings or stuff like that). I would like to intercept POSTs to the microjax servlet with some custom logic (in a script). If that is possible all the simpler validation stuff (like checking for required values) can be implemented (by an application writer) as well if someone wishes to do so. When this was first discussed I think the result was to implement the POST script. But I would like to extend the behavior of the PostServlet without having to reimplement everything it does. That would be something like implement the POST script (do some validation there) and pass on the request to the POST servlet or not (depending on the validation). Cheers Michael On 12/6/07, David Nuescheler [EMAIL PROTECTED] wrote: hi carsten, hehe ;) He, you're taking all the fun out of this discussion :) Now, I think it makes sense to have an additional validation mechanism on top of JCR. I guess with the node type definitions you can't handle all validation cases (like validating one field depends on the value of another one etc.). So we need these hooks. i am all for a general validate() hook. (... to take care of the dream-case. ;) ) It makes sense to leverage the validation information from the nodetypes, of course. And I also think that it makes sense to validate the input based on this information before a commit. So some sort of general service doing this would be great... excellent. then all the general cases from xss to integer validation can easily be taken care of via regular nodetype definition. regards, david -- Michael Marth, http://dev.day.com
Re: [jira] Commented: (SLING-114) ECT - Ecmascript Client Templates
Bertrand, 2 things I wonder about: 1. would it be better to produce output like: p class= document.write(item.color); \ document.write(item.text); /p So that e.g. search engines could index the static parts? 2. Having the same templating language on client and server is nice, but maybe different delimiters would be a good idea. If the same ones are used we cannot combine server-side and client-side parts in one script. This seems like an unnecessary limitation to me. btw: reminded me of the TrimPath stuff now at http://code.google.com/p/trimpath/wiki/JavaScriptTemplates Cheers Michael On 11/29/07, Bertrand Delacretaz (JIRA) [EMAIL PROTECTED] wrote: [ https://issues.apache.org/jira/browse/SLING-114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12546652] Bertrand Delacretaz commented on SLING-114: --- Thanks for the hint, didn't know about that.

Re: microsling scripting for POSTs
Hi Felix, implementing a servlet or a servlet filter takes me back to coding Java. It is my understanding that at least microsling (not necessarily Sling) should allow me to code JCR-based web apps in scripting languages (ie. that my scripts are able to write into the repository).

microsling scripting for POSTs

Re: Script engines as plugins?
If you mean plugins written in Java, that would be Sling OSGi I guess...it might seem like a big beast now, but once refactored to the new sling-api, Sling OSGi shouldn't be much harder to use than microsling for simple things. So we could assume that people with that kind of needs would graduate to Sling OSGi, OTOH if by plugins you mean scripts that can be reused as software components in other scripts, that's a different topic, that might be interesting to explore...a bit later maybe ;-) Well, I deliberately stayed away from the question how an application-level plugin mechanism should be implemented. But, yes, I meant scripts that can be reused (but not necessarily just visual components). I agree, this discussion is probably a bit too early.
Re: microsling user feedback
Hi, I gave it a shot to put the static resources in the repository and access them through WebDAV. It worked, but there is one issue that I would like to mention in this discussion about the correct implementation: Even for resources that are readable for for anonymous users I get the basic authentication popup of the browser. Surely, this can be suppressed (maybe by wrapping the WebDAV servlet?). But this also made me wonder how the single-sign-on would work between a (raw, unwrapped) WebDAV-based part (that uses basic authent) and microsling (that uses the jsessionid cookie/Java appserver mechanisms)? microsling could of course accept the basic authentication headers if a WebDAV login occurred first, but how would it work the other way round?

I think this is very easy to understand for everybody and means that microsling generally works just like every other WebDAV enabled webserver for everything that is static. This sounds very plausible, but has some implications, which turn out to be somewhat problematic. Therefore, I just added a StreamServlet which streams a resource of type nt:file (which is most likely what is required by Michael) and in addition support If-Modified-Since header such that a 304 may be sent back just in case. This more or less should match, what WebDAV does in this respect, and I think we are done without any special handling. Personally, I think that this is a very simple and straightforward solution that leverages a lot of features implemented in WebDAV entirely correctly. Think of etag or modified since behaviour on GET or PUT and DELETE which all would have to be re-implemented in microsling. Streaming out of a Sling Application currently only discusses reading (GET) not updating, which is done as described by Betrand using access to the WebDAV servlet included with microsling. Generally I think WebDAV is very Restful and a very good basis to start and sort of decorate microsling on top of a webdav enabled server. This sounds like an interesting point, though: Running Sling/microsling ontop of a WebDAV server instead of a repository :-) I think assuming assuming that people add an extension to let's say /content/mypage when GETting /content/mypage.html though microsling is good practice anyway. Definitely, it also helps determine the default response content type. Regards Felix
