Java XDocReport不是ImageIO SPI类

大家好，请帮帮我。我是一名新的java web开发人员。我尝试了XDocReport，用邮件合并系统创建Word和PDF文档，一切看起来都很好。但当我试图在服务器上安装它时，它抛出以下异常：

我将Java 8用于本地和服务器：

在我的IDE上，Netbeans看起来一切都很好。我也试过自己的tomcat，没问题。但当我在服务器上部署它时，错误总是发生的。请帮帮我

这是完全错误：

大家好，欢迎来到StackOverflow。我想我们需要更多的细节（哪台服务器？错误是否与代码相关？…）hi@baitmbarek thans，以便您快速响应。我的服务器是带有Tomcat 9和MySQL数据库的Windows服务器。我认为它与代码没有联系，因为一切工作都可以在IDE上找到，还有我自己的本地tomcat。我从这里了解到，您自己的Tomcat代码与windows服务器上的代码相同吗？（版本和配置）。另外，您的服务器是否使用Java8（JRE1.8）？是的，这是不同的。我的是Tomcat8，但配置相同。您是否可以打包您自己的tomcat或下载一个新的tomcat 8并将其部署到您的服务器上，然后在其中安装war？将有助于确定问题是否与Tomcat有关。
