I wonder if it's referring to you having to set the format to some kind of default. in web script descriptor, set the default so something valid, i.e. html, xml, etc.

<format default="html">argument</format>

Also, there are several samples of java-backed web scripts here:

thanks, the first and second examples works fine.

For now my workaround is to hard code authentication into the source code of the second example (RandomSelectWebScript.java).
the modifs are:
private TransactionService transactionService;
private Logger logger = Logger.getLogger(RandomSelectWebScript.class);

    public void execute(WebScriptRequest req, WebScriptResponse res)
        throws IOException
    {
   boolean switchUser = false;

      String currentUser = AuthenticationUtil.getCurrentUserName();
      if (!currentUser.equals("admin")) {
         //logger.debug("Current user is not admin so switching to admin");
         AuthenticationUtil.setCurrentUser("admin");
         switchUser = true;
      }

      UserTransaction txn = transactionService.getUserTransaction();

      try {
         txn.begin();


       // get the referenced incoming node
       NodeRef rootNodeRef = getNodeRef(req);

       // draw a random child
       NodeRef childNodeRef = randomChild(rootNodeRef);

       // stream child back
       output(res, childNodeRef);

      } catch(Throwable e) {
         try {
            if (txn.getStatus() == Status.STATUS_ACTIVE) txn.rollback();
         } catch (Throwable ee) {
            e.printStackTrace();
         }
      }

      if (switchUser) AuthenticationUtil.setCurrentUser(currentUser);

    }

I changed also the description of the WS to :
<webscript>
<shortname>Streams a random content item</shortname>
<description>Streams a random content item</description>
<url>/demo/random?path={path}</url>
<authentication>guest</authentication>
<transaction>none</transaction>
<format default="">argument</format>
</webscript>

But it doesn't work ?!

Thanks in advance,
Tegel
