提供调用的static 工具类SambaUtil.java:

测试类SambaUtilTest.java：
package com.sillycat.api.commons.utils;

import junit.framework.TestCase;

public class SambaUtilTest extends TestCase {

protected void setUp() throws Exception {
   super.setUp();
}

protected void tearDown() throws Exception {
   super.tearDown();
}

public void testDummy() {
   assertTrue(true);
}

public void testCreateDir() {
   String dir = "www.sillycat.com/share/test1";
   SambaUtil.mkdir(dir, "guest", "guest");
   SambaUtil.mkfile(dir + "/test2.txt", "guest", "guest", "<html></html>中文hello world!");
   String tmp = SambaUtil.readfile(dir + "/test2.txt", "guest", "guest");
   System.out.println(tmp);
   SambaUtil.delete(dir + "/test2.txt", "guest", "guest");
}
}


报错：
jcifs.smb.SmbException: The network name cannot be found.

原来是我的filepath写错了,写成www.sillycat.com/test1
改成www.sillycat.com/share/test1就OK了

报错：
jcifs.smb.SmbException: The process cannot access the file because it is being used by another process.

原来是方法里面的
SmbFileInputStream in = new SmbFileInputStream(f);
SmbFileOutputStream out = new SmbFileOutputStream(to);
这个in 和 out 都要注意 close，我有一个忘记close了。。。汗
