I registered a servlet in Java Web Server and since then I have stopped the JWS and trying to restart the same. But I have been unable to do so. I have tried it on a different machine and it worked perfectly fine. No procedure was changed. I am getting an error like this one :
javawebserver: Java Web Server ERROR: Protected file protected.html does not exist
javawebserver: Java Web Server ERROR: ACL configuration error: com.sun.server.realm.NoSuchAclException: change.
javawebserver: com.sun.server.realm.NoSuchAclException: change

javawebserver: at com.sun.server.http.HttpService.run(Compiled Code)
javawebserver: at java.lang.Thread.run(Compiled Code)

whereas the file does exist. I cant seem to figure out what the problem is now.
Kindly reply ASAP.
