[GraphHopper] How to load *-gh folder? "it wasn't create via com.graphhopper.storage.GraphStorage" exception

[Nishiura Kazuki]

Hi Peter,
I'm not sure which you meant;1) rewrite my program as gh.load("/something/berlin");2) rename berlin-gh folder as berlin, and also rewrite user program

I tried both and got the same exception.IllegalStateException: Cannot load the graph

I'll create a issue on github.Thanks,
Kazuki

    Hi Kazuki,

      

      does the folder without -gh work? If yes, please create an issue.

      

      Regards,

      Peter.

      

    
    
      
      Hi, 
        

        
        How can I load *-gh folder obtained by graphhopper.sh?
        I first tried your web version; 
        ./graphhopper.sh  web europe_germany_berlin.osm
        and it works fine.
        However, when I try to load
          generated europe_germany_berlin-gh folder (I saw same
          exception for other region), it raises an exception;
        

        
        
          Exception in thread "main"
            java.lang.IllegalStateException: Cannot load the graph - it
            wasn't create via com.graphhopper.storage.GraphStorage!

com.graphhopper.storage.GraphStorage.loadExisting(GraphStorage.java:1310)
           at
            com.graphhopper.GraphHopper.load(GraphHopper.java:476)
           at
            GraphTest.main(GraphTest.java:20)
        
        

        
        Here is code I wrote;
        
                  GraphHopperAPI gh = new
            GraphHopper().forServer();
                 
            gh.load("/home/kazuki/dev/graphhopper/europe_germany_berlin-gh");
        
        

        
        This is a wiki page I refered
        https://github.com/graphhopper/graphhopper/wiki/Developers
        

        
        How can I load *-gh folder ?
        

        
        Thanks!
