Hi,
Anyone have experience with getting an embedded Neo4j database running on GWT? I get an AccessControlException when I create the embedded database server side.
Here's my stacktrace:
SEVERE: javax.servlet.ServletContext log: Exception while dispatching incoming RPC call
com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract com.coreywu.uwcompanygraph.client.CompanyGraph com.coreywu.uwcompanygraph.client.QueryGraphService.getGraph()' threw an unexpected exception: java.security.AccessControlException: access denied ("java.io.FilePermission" "\var\uwcompanygraph" "read")
