Hi Oliver and thanks for the quick response!
Got a few more question :)

Hi Eirikur!

I agree many things are confusing, as apropriate, up to date  
documentation is yet a weak spot of Slide. But, once you get it,  
Slide's architecture actually is quite obvious and nice. I will try to  
add more docs as soon as possible and will also try to talk other  
people into writing some. How about you when you have finally solved  
your problems ;)
Sure when I get to that point I will probably be an expert on what not  
to do ; )

Anyway, to have Slide use your stores for content and user information  
you will have to provide your own implementation of  
org.apache.slide.store.ContentStore and  
org.apache.slide.store.SecurityStore.
Are there any docs on what the methods in those interfaces should  
actually be doing? Example from ContentStore interface:
 NodeRevisionContent retrieveRevisionContent (Uri uri,  
NodeRevisionDescriptor revisionDescriptor)
I can figure out what the NodeRevisionContent and the descriptor but  
what does the "uri" contain when you are using a database as a  
repository?

Also are you forced to use versioning of files? We haven't yet  
implemented versions for files in our system.

 You will have to configure your implementation in Domain.xml as well.  
Consider Eirikur.filestore implements  
org.apache.slide.store.ContentStore and Eirikur.userstore implements  
org.apache.slide.store.SecurityStore this configuration taken over  
from the standard configuration of a J2EE store might be what you  
have:

     <store name="j2ee" >
         <nodestore classname="org.apache.slide.store.impl.rdbms.J2EE">
            <parameter name="datasource">jdbc/mtx</parameter>
            <parameter  
name="adapter">org.apache.slide.store.impl.rdbms.SQLServerRDBMSAdapter< 
/parameter>
              <parameter name="compress">true</parameter>
What does the org.apache.slide.store.impl.rdbms.J2EE handle then? What  
are the "rest" of the stores?
And what does compress true mean?

    </nodestore>
      <contentstore classname="Eirikur.filestore">
      </contentstore>
        <securitystore classname="Eirikur.userstore">
        </securitystore>
        <lockstore>
          <reference store="nodestore" />
        </lockstore>
        <revisiondescriptorsstore>
          <reference store="nodestore" />
        </revisiondescriptorsstore>
        <revisiondescriptorstore>
          <reference store="nodestore" />
        </revisiondescriptorstore>
      </store>
      <scope match="/" store="j2ee"/>


For a reference how to implement those interfaces have a look at
org.apache.slide.store.txfile.TxFileContentStore as the default  
implementation for the content store and  
org.apache.slide.store.impl.rdbms.J2EEStore for both.

Hope this helps as a starting point and this is the information you  
were looking for. Feel free to come back to the list for any open  
issues.

Yes it really helps thank you : )

Best regards

Hi all,
I have been sitting on the sidelines watching this developer  
mailinglist to try to figure out what strategy to take in my  
integration of Slide into our web application framework. We have a  
pure object based J2EE web framework (almost JSF compliant ;) that  
has it's own database driven filesystem and user system (with roles  
and group permissions) and would like to make the filesystem  
available through WebDAV with Slide. We are also working on embedding  
an java LDAP server that some guys at codehause.org have resurrected  
from a dead to open up our user system to others and there we only  
have to implement our own backend.
In my little knowledge of Slide it seems to be the same task at hand  
but it's very...very confusing as to what exactly we need to do?
What do we have to do so Slide uses our user system for  
authentication (possible through LDAP) and our filesystem as a  
supplier of the files and folders published in webdav?
Please give me two scenarios a) where we use our own file system  
data-structure b) we use the data-structure that comes with Slide and  
somehow just link to it.
Hope someone has the answers : )
Thanks in advance for any help you can give me and congratulations on  
the beta version coming out...
