我在 Eclipse 中使用 JSP 和 Spring MVC 开发了一个 Web 应用程序。当我在 Eclipse 中运行应用程序时运行良好，但是当我在 tomcat 7 中加载 war 文件时，当应用程序必须打印票时它不会，并且不会引发错误。下一个日志来自本地主机访问

Catalina log it ok without errors 下一部分是 catalina log.jul 的最后几行

在程序中创建一个文件来打印它。打印该文件的方法如下：

public void imprimir(String ticketName){
    DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
    //use the default printer
    PrintService service = PrintServiceLookup.lookupDefaultPrintService();
    if (service != null) {
        try {
            //create a print job
            DocPrintJob job = service.createPrintJob();
            //attributes of the job
            DocAttributeSet das = new HashDocAttributeSet();
            FileInputStream fis = new FileInputStream(ticket+".txt");
            Doc doc = new SimpleDoc(fis,flavor,das);
            try {
                //the job is send it to the printer
                job.print(doc,null);
            }
            catch(Exception e){
                e.printStackTrace();
            }
        }
        catch(Exception e){
            e.printStackTrace();
        }
    }
}

我发现问题是要打印的文件的路径，当我的应用程序在warfile的路径中打印时，tomcat会在文件夹的根目录中创建文件
