title: db derby StartNetworkServer
body: <p>I have problem with starting derby server.
  My derby version: db-derby-10.11.1.1</p>
  
  <p>I followed this tutorial:
  <a href="http://db.apache.org/derby/papers/DerbyTut/ns_intro.html" rel="noreferrer">http://db.apache.org/derby/papers/DerbyTut/ns_intro.html</a></p>
  
  <p>but after typing: startNetworkServer.bat there is no response:

  <p>Could you help me? 
  Maybe there is some problem with my localhost?
  I think that i install Derby correctly because after typing: java org.apache.derby.tools.sysinfo
  I got some result</p>
  
  <p>regards</p>
