我正在使用JasperStudio和Jasper server 6.2 windows版本。在本地环境中，我首先测试了数据源，postgreSQL JDBC连接，成功连接，我创建了一个域并链接了数据源。我拿了需要输入字符串的工作jrxml文件。我在视图中创建了报告＆gt; repository＆gt; create＆gt; jasperReport，在配置报告时，我已经提供了生产服务器中的jrxml文件，并将输入字段设置为必填项。到目前为止一切都很好但是当我点击报告时它要求输入值，当给出输入值并且单击应用时，它显示以下错误消息：

当我尝试在JasperStudio中编译相同的jrxml时，它会给我一个带有设计的空报表，但是当选择空数据适配器时它没有数据，并且在选择数据源时它会提供完整的空文档。
