Oracle BI报表服务返回0大小的字节数组

Question

当我在Oracle Bi report v12c中的Oracle Bi Service中调用runReport时，返回的byteArray为null！！！请帮帮我！

我的代码：

public static void main(String[] args) {
ReportService_Service reportService_Service = new ReportService_Service();
ReportService reportService = reportService_Service.getReportService();
ReportRequest reportRequest = new ReportRequest();
reportRequest.setAttributeFormat("pdf");
reportRequest.setAttributeLocale("en-US");
reportRequest.setAttributeTemplate("Simple");
reportRequest.setReportAbsolutePath("/Ehsan/HrEmployeeReport.xdo");
ParamNameValues allParam = new ParamNameValues();
ArrayOfParamNameValue pNameValue = new ArrayOfParamNameValue();
ParamNameValue nameValue = new ParamNameValue();
nameValue.setName("salParam");
ArrayOfString aos = new ArrayOfString();
aos.getItem().add("13000");
nameValue.setValues(aos);
pNameValue.getItem().add(nameValue);
allParam.setListOfParamNameValues(pNameValue);
reportRequest.setParameterNameValues(allParam);
try {
File newFile = new File("D:/a/b.pdf");
FileOutputStream fos = new FileOutputStream(newFile);
ReportResponse response = new ReportResponse();
response = reportService.runReport(reportRequest, "weblogic", "weblogic1");
System.out.println(response.getReportContentType());
System.out.println(response.getReportFileID());
System.out.println(response.getReportBytes().length);
fos.write(response.getReportBytes());
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
}

输出：

1. application/pdf
2. xmlp4736064089125233107tmp
3. 0

尝试添加：

reportRequest.setSizeOfDataChunkDownload(-1);

在您的代码中。
