Issue about BI JAVA SDK-SOAP request failed with return message 2147483653

Question

Dear Experts,
I'm trying to use BI JAVA SDK to connect BW by using XMLA connector.
But there's an error messaet said :
SOAP request failed with return message 2147483653 ( Invalid MDX command with INCLUDING)
I'm really new to this JAVA SDK, and after searching help in SAP Service Market and Google, there's no helpful suggestion.
please help me about how to fix this error.
Here is my code:
IBIConnection connection = (IBIConnection) cf.getConnectionEx(cs);
      IBIOlap olap = connection.getOlap();
      Cube cube = olap.getObjectFinder().
      findCubeFirst((String)null, "ZFI_C11/ZFI_C11_Q001");
    // This is just a sanity check to verify that the
    // cube on which this example relies was retrieved 
    if (cube==null){
        System.out.println("no cube found");
// Didn't print out this message, seems it can connect to BW and get the InfoCube and Query.
    Dimension plantDimension = olap.getObjectFinder().
    findDimensionFirst(cube, "ZPLANT");
  Dimension materialDimension = olap.getObjectFinder().
    findDimensionFirst(cube, "ZMATERIAL"); 
  IBIQuery query = olap.createQuery(cube);
  IBICommandProcessor commandProcessor = query.getCommandProcessor();
  commandProcessor.moveDimensionToRows(plantDimension);
  commandProcessor.moveDimensionToRows(materialDimension);
  IBIDataSet dataset = query.execute(); // After execute this statement, error happens.
Thank you!

Solved myself, it's because the query used in my code have user input variable.
