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

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();
}
}
}
