原来文件中file: 后面用的是相对路径，我调试的时候老说examples/data/university0-0.owl（系统找不到指定路径）我就把三个file指向文件的相对路径该为绝对的，就没报原来的错误，可现在在执行时又有这样的错误：

WARN [main] (OntDocumentManager.java:1078) - An error occurred while attempting to read from file:examples/data/univ-bench.owl. Msg was 'Not found: file:examples/data/univ-bench.owl'.

  }

我感觉现在比原来的错误好了一点，现在就是在查询的时候没找到An error occurred while attempting to read from file:examples/data/univ-bench.owl. Msg was 'Not found: file:examples/data/univ-bench.owl'.
lubm-query4.sparql中的内容是这样的：
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX ub: <http://www.lehigh.edu/~zhp2/2004/0401/univ-bench.owl#>

SELECT ?X ?Y1 ?Y2 ?Y3
WHERE
{?X rdf:type ub:Professor .
?X ub:worksFor <http://www.Department0.University0.edu> .
?X ub:name ?Y1 .
?X ub:emailAddress ?Y2 .
?X ub:telephone ?Y3}
我不知道这是什么原因，不知道您可不可以帮帮我，谢谢了。
