Hello, This is something which is fixed in the development branch and I had thought was fixed in the release as well. Do you have the rest of the stack trace? I believe that it goes through one of the key-value store (com.bigdata.sparse) atomic update classes. Thanks, Bryan ________________________________________ From: Isr...@th...

Subject: using nanoSparqlServer with federation Hi, I have installed a federation on 9 machines using the bigdataCluster16.config example which seems to work fine (used the latest BIGDATA_RELEASE_1_0_0 branch). Then I have started a nanoSparqlServer.sh and I can access its /status and /counters URLs. However, when I try to POST a new URI I get the following exception: <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/> <title>Error 500 java.lang.RuntimeException: java.lang.RuntimeException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.util.concurrent.ExecutionException: java.lang.ClassCastException: com.bigdata.btree.BTree cannot be cast to com.bigdata.service.ndx.IClientIndex</title> </head> <body> <h2>HTTP ERROR: 500</h2> <p>Problem accessing /sparql.
