HI:
   
  As I remembered , in the launchpad app project.
I can run a sling demo only with a jar (with java -jar command ), to my
surprise the latest versioin can't work well.

  Now I want to do it too , which jar can I use?
Has the architecture been changed in the launchpad?

Re: How can I use a jar to run sling

[paksegu]

I am able to run sling lunchpad app by following example below
http://incubator.apache.org/sling/site/getting-and-building-sling.html
 
set JAVA_HOME=C:\jdk
set PATH=%JAVA_HOME%\bin
set M2_HOME=C:\maven
set PATH=%M2_HOME%\bin
set MAVEN_OPTS=-Xmx256m

cd /sling
mvn clean install
 
I have notice that sometimes the jcrapp jar does not build, unless you
 
cd /sling/launchpad/jcrapp
mvn clean install
 
then when the build is done
 
Java -jar target/org.apache.sling.launchpad.jcrapp-2.0.0-incubator-SNAPSHOT.jar 
-c sling -f -
 
this should work 
Cheers

This is not currently possible (though the implementation would be
rather simple).

The problem is that we also support WebDAV on "/" through the Sling
WebDAV bundle. So, for WebDAV we might want to expect the script to be
returned as plaintext to be able to edit and modify it.

I could imagine two options: (1) we add a configuration setting, which
controls whether scripts are executed or not or (2) add a servlet to
handle a special extension, which would execute the script. I would
prefer this second option.



Maybe it could be possible to set a resource type, sling:Script on  
these, to allow execution? They could be edited if accessed through  
the /dav/ prefix.

Hmm, the last time I checked, they did run on my box.

Would it be possible to get the test results, best in a JIRA issue. Thanks.

Yes, there are two GWT modules in the Sling project inside the
extensions/gwt folder: The servlet module provides the basic Server Side
infrastructure and is required. The sample module is a sample GWT form.

This artifact is not available from the central maven repository but
from the OPS4J repository.

The Sling launchpad/app module is set up to find the artifact correctly.
If you need it in your own module, you might want to add the following
repository definition to your pom.xml:


OPS4J
OPS4J Repository
http://repository.ops4j.org/maven2

true


false

You might want to create a /apps/sling/content/error404 node, set the
sling:resourceType, title, and text properties and in your error handler
you do:

<%
sling.include("/apps/sling/content/error404.html");
%>

This will return a page with your decorator etc.

Re: A question about sling launchpad

[Felix Meschberger]

Hi Yan,

As Betrand said, this is actually a (known) bug in the definition of the
OCM bundle of Sling. If you don't need/use OCM (Object Content Mapping),
you can safely ignore this error.

Anyway, I know of this problem and will fix it later this week.

Felix

   Servlet servlet = ((SlingHttpServletRequest) req).

[newbie] WebDav - Content Negociation

[JY]

I want to make a simple wiki where pages can be edited by WebDav. 
Several formats can be available.


For example: The page http://example.com/main can be modified by one of 
this file :


/
|- main.html (for modifications with an HTML Editor like DreamWeaver)
|- main.doc (for modifications with MS Office)
|- main.odt (for modifications with OpenOffice)
|- main.wiki (for modifications with Notepad with Wiki Syntax)
|- main.pdf (read-only PDF format for export)

Can Sling help me to do that?

Re: Can't use some JCR classes in Sling

[Joshua Oransky]

Toby,

	I'm trying to create a script that can replicate a node, so I need  
access to these classes. I'm using the content.jsp code from the CRX  
webapp, but I want the code to reside INSIDE my app, so that I can  
package it up and send it to the servers I need, since I wont have  
access to the command line or FS.


Here's my code:

	String action_arg0 = currentNode.getPath(); try  
{ com.day.crx.replication.ReplicationManager mgr =  
(com.day.crx.replication.ReplicationManager)  
((com.day.crx.core.CRXRepositoryImpl)  
repSession 
.getRepository 
()).getModule 
(com.day.crx.replication.ReplicationManager.class.getName()); if (mgr  
== null) { %>Replication not configured<% } else  
{ mgr.replicate( repSession, "Activate", action_arg0, null, false,  
null ); %>  alert("Replication of Node <
