为什么我的java web应用程序不能在tomcat7中发送打印

Question

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，它工作得很好，但是当我在tomcat7中加载war文件时，当应用程序必须打印票证时，它不会这样做，也不会抛出错误。下一个日志来自localhost访问

Catalina日志没有错误。下一部分是catalina log.jul的最后几行。

在程序中，会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();
        }
    }
}

我发现问题出在要打印的文件的路径上，当我的应用程序在warfile的路径下打印时，tomcat会在文件夹的根目录下创建该文件
