linux利用poi读取word文档的问题

[dsn21]

大家好,小弟近日遇到问题,写好的程序在windows下是可以正常读取 word的,但迁移到linux时就报如下的错误:

java.io.IOException: Invalid header signature; read 2314885530818453536, expected -2226271756974174256

at com.bit.dlde.resourcetrans.ui.ResourceTransUI$PackageAction$1.run(ResourceTransUI.java:523)
并且引起错误的地方是: POIFSFileSystem fsys = new POIFSFileSystem(in); 希望有高人指点一下啊!!谢谢拉!!

这个设了没有?感觉错误应该与操作系统的默认编码有关
response.setContentType("application/vnd.ms-excel;charset=utf-8");
