我正在使用CypersQueries從Java Applicaton創建節點。我按照上面的鏈接如何在Java中使用Neo4j的cyper查詢應用程序
http://docs.neo4j.org/chunked/milestone/query-create.html
在我javaApplication我用一個簡單的查詢如上
public class CretaeQuery
{
public static final String DBPATH="D:/Neo4j/CQL";
public static void main(String args[])
{
GraphDatabaseService path=new EmbeddedGraphDatabase(DBPATH);
Transaction tx=path.beginTx();
try
{
Map<String, Object> props = new HashMap<String, Object>();
props .put("name", "Sharon");
props .put("position", "Engineer");
Map<String, Object> params = new HashMap<String, Object>();
params.put("props", props );
ExecutionEngine engine=new ExecutionEngine(path);
ExecutionResult result=engine.execute("create ({props})", params);
System.out.println(result);
tx.success();
}
finally
{
tx.finish();
path.shutdown();
}
}
}
當我運行上面的類,我面對上述eror
Exception in thread "main" java.lang.NoClassDefFoundError: com/googlecode/concurrentlinkedhashmap/ConcurrentLinkedHashMap$Builder

我不知道爲什麼錯誤是拋出。請用適當的代碼給我建議
嗨,我在類路徑中缺少的jar。我在Windows 32位中使用neo4j-community-1.9-SNAPSHOT.zip。 – Navyah
嵌入式模式還是REST? –
