Question

我创建了一个简单的BIRT报告，它使用两个不同的DataSet从两个DB表中选择数据。它还有两个传递给DataSet查询的参数。

我的问题是，当我从Eclipse + BIRT环境运行报表时，它会按原样获取所有数据，但是当我从Grails birt-report服务运行报表时，它只打印静态骨架，但不会来自DB的数据。

首先我认为传递给服务的参数值有问题，所以我在报告中添加了一行来打印这些值。这些参数被传递并打印出来然后我从查询中删除了 where 部分，但仍然没有发生任何事情。该报告在从Eclipse运行时填写，在 birt-report 插件中运行时为空。

这是我用来打印报告的代码：

    params.remove('action')
    params.remove('controller')
    params.remove('name')

    params.put("userId", 10)   //parameter that should be passed
    params.put("resumeId", 5)  //parameter that should be passed

    println params;

    def options = birtReportService.getRenderOption(request, 'doc')
    def result=birtReportService.runAndRender(reportName, params, options)
    response.setHeader("Content-disposition", "attachment; filename=" +reportName + "."+reportExt);
    response.contentType = 'application/doc'
    response.outputStream << result.toByteArray()

任何想法可能是什么原因？

UPD：我如何调试它以查看内部真正发生的事情？

UPD 2：看起来它与应用程序有关，因为当我在新的Grails应用程序中启动报告时，它可以正常工作。

我在查看调试日志时发现的成功和失败启动之间的唯一区别是：

在这两种情况下都使用了相同的报告文件。

在birt-report插件中运行时，BIRT报告不会打印dataSetRow [“name”]值
