I've been trying to start learning SGS.  My goal right now is to get the server running and do something as simple as printing out a message to the console in my BootGLO class.  The problem is that I run into this error before I get there.  I've tried everything I can think of but I keep getting the following error:

java.lang.StringIndexOutOfBoundsException: String index out of range: -1
        at java.lang.String.substring(String.java:1768)
        at com.sun.gi.framework.install.impl.InstallationURL.<init>(InstallationURL.java:121)
        at com.sun.gi.framework.install.impl.DeployerImpl.<init>(DeployerImpl.java:123)
        at com.sun.gi.SGS.<init>(SGS.java:128)
        at com.sun.gi.SGS.main(SGS.java:197)
java.lang.InstantiationException: Missing Installation Loader
        at com.sun.gi.framework.install.impl.DeployerImpl.<init>(DeployerImpl.java:129)
        at com.sun.gi.SGS.<init>(SGS.java:128)
        at com.sun.gi.SGS.main(SGS.java:197)

Here's what my files look like (I think these are the relevant ones)

SGS-apps.conf

#This file describes the games installed into this back end as a list of one line entries
#The entries make up a 2 column able as follows
#Game ID   URL Location of deployment XML

1   file:zombieSurvival_Deployment.xml

zombieSurvival_Deployment.xml

<GAMEAPP gamename="ZombieSurvival">
   <GLEAPP bootclass="server.BootGLO" classpathURL="file:."></GLEAPP>
   <USERMANAGER serverclass="com.sun.gi.comm.users.server.impl.TCPIPUserManager" reconnect_key_ttl="30">
      <PARAMETER tag="host" value="127.0.0.1"></PARAMETER>
      <PARAMETER tag="port" value="1150"></PARAMETER>
      <VALIDATOR moduleclass="com.sun.gi.comm.users.validation.impl.FlatFileUserValidator">
         <PARAMETER tag="password_file_url" value="file:passwd.txt"></PARAMETER></VALIDATOR></USERMANAGER></GAMEAPP>

These two files are in the same directory.

Nothing I did with changing the classpath or bootclass changed the error.  Any help would be appreciated, as I am completely stumped.

Ok I fixed the problem.

Apparently, regardless of the values you enter for the file path to the server deployment XML file and the way your file system is structured, the server won't recognize your boot class unless it is located in an apps folder.  I don't know if this is a bug or not, but you would think that you could structure your files however you wanted.  Anyone have any insight on this?
