accessing file via slide

[Claus Goettfert <cl...@gmx.net>]

hi all,

I use retail slide 1.0.16 and run into problems when trying to access a 
file via slide. I used an example posted previously here but I always get a 
nullpointerexception whatever path variation I try on line

             NodeRevisionDescriptors revisionDescriptors = 
content.retrieve(slideToken, "/files/test.txt");

I use slide out of the box except adding a user for accessing the tomcat 
manager (via tomcat-users.xml) and setting a password for user john in 
/conf/slide/slide.data.

I used the user john to add the "test.txt" file to /files/ via "my network 
places". so there is a file "/files/test.txt" via webdav client and a file 
called "jakarta-slide/server/contentstore/files/test.txt_1.0" even after 
stopping, restarting slide.

additionally changing the "rootpath" in domain.xml doesn't seem to have any 
effect (see below?). slide always stores files in 
jakarta-slide/server/contentstore (slide server started from 
jakarta-slide/server/, the Domain.xml file is also located at 
jakarta-slide/server/Domain.xml).

here is my sourcecode:

<--->
PrintWriter out = response.getWriter();
    try{
             NamespaceAccessToken token = Domain.accessNamespace(new 
SecurityToken(""), "slide");

             Structure structure = token.getStructureHelper();
             Security security = token.getSecurityHelper();
             Lock lock = token.getLockHelper();
             Content content = token.getContentHelper();


             CredentialsToken credToken =
                 new CredentialsToken(new String("john"));
             SlideToken slideToken = new SlideTokenImpl(credToken);

            // structure.create(slideToken, new SubjectNode(), 
"/files/slideTestFolder");

             NodeRevisionDescriptors revisionDescriptors = 
content.retrieve(slideToken, "/files/test.txt");

              } catch (Exception ex) {
              ex.printStackTrace(out);
          }

<-->

when executing the servlet slide throws exceptions like:

ClassCastException: slidestore.reference.MemoryDescriptorsStore
....
ClassCastException: slidestore.reference.FileContentStore
....
ClassCastException: slidestore.reference.DefaultStore
.....

or warnings like:
org.apache.slide.common.Domain - WARNING - Service memory 
(org.apache.slide.store.StandardStore) access error : 
org.apache.slide.common.SlideException: caus is empty

and a nullpointerexception.

all on line:

             NamespaceAccessToken token = Domain.accessNamespace(new 
SecurityToken(""), "slide");

...

can anyone please give me some hints what is wrong? or point me to some 
examples how to use the slide api (simple file access, property access or 
similar)? i didn't find anything, the examples provided seem to cover some 
other topics.

regards,

claus goettfert
