<br>
CH shortcuts are enabled by default in the example configuration
and so it assumes a LevelGraphStorage. Turn this config off or use
the Java code to load it:<br>
<br>
hopper.setCHShortcuts(true, true)<br>
<br>

<p>Hi,</p>
<p>I've been following the guide
<a class="moz-txt-link-freetext" href="https://github.com/graphhopper/graphhopper/wiki/Developers">https://github.com/graphhopper/graphhopper/wiki/Developers</a>. I
can build a graph by calling this in cygwin:</p>
<p>./graphhopper.sh web europe_germany_berlin.osm</p>
<p>I then try loading it in code using:</p>
<p>GraphHopperAPI gh = new GraphHopper().forServer();<br>
gh.load("D:\\Processing\\Graphhopper\\graphhopper\\europe_germany_berlin-gh");</p>
<p>but it gives me this exception:</p>
<p>Exception in thread "main" java.lang.IllegalStateException:
Cannot load the graph - it wasn't create via
com.graphhopper.storage.GraphStorage!
D:\Processing\Graphhopper\graphhopper\europe_germany_berlin-gh/</p>
<p>which happens when it checks the first int from the header of
the nodes DataAccess object against the hashcode of the
GraphStorage class name.</p>
<p>What am I doing wrong? When you build a graph from the command
line does it create it using a different class, not
GraphStorage? Or does Maven somehow build GraphStorage into a
different namespace?</p>
<p>many thanks</p>
<p>Phil</p>
