I'm evaluating Spectacle as the presentation framework for RDF output(not sure if there's any other good tools can do this?). Just got some problems. Could anyone kindly answer my questions? Thanks in advance!

   I can't find any mysql user/password definition in spectacle.war file, how does spectacle connect to mysql db if there's no user/pass defined?
   Is it a must to set up virtual host for running spectacle samples on Spectacle Web Server? can I simply use localhost as host?
   When I tried to run ant to build the Spectacle sample, it ask me to input the hostname of the Spectacle Server and the password, where is the password defined? if I use localhost as hostname and leave empty or input anything as password, it just throw exception. What should I input?
   Is there any more doc besides http://www.aidministrator.nl/spectacle/index.html ? I'm building a research project with Sesame and would like to use Spectacle to do the presentation of RDF output, I don't know how can Spectacle integrate with the search result from Sesame?
   When I tried to deploy spectacle.war file to JBoss3.2.2, I always encounter below exception, can anyone help?
