smb文件復制異常

Question

我正在嘗試將jar文件復制到Windows共享文件夾，並且我正在使用smb來執行此操作，但出現以下錯誤。 還有其他方法可以復制文件嗎？

    String user = "abc";
    String pass ="xyz";
    try{
        String sharedFolder="tmp/share/sample.jar";
        String path="smb://1.2.3.4/"+sharedFolder;
        NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("",user, pass);
        SmbFile smbFile = new SmbFile(path,auth);
        SmbFile localFile = new SmbFile("C:/abc/exz/sample.jar");
        localFile.copyTo(smbFile);

    }catch(Exception e){
        e.printStackTrace();
    }

例外情況：

jcifs.smb.SmbException: Failed to negotiate
jcifs.smb.SmbException: Timeout trying to open socket
    at jcifs.smb.SmbTransport.start(SmbTransport.java:315)
    at jcifs.smb.SmbTransport.negotiate0(SmbTransport.java:865)
    at jcifs.smb.SmbTransport.negotiate(SmbTransport.java:941)
    at jcifs.smb.SmbTree.treeConnect(SmbTree.java:119)
    at jcifs.smb.SmbFile.connect(SmbFile.java:827)
    at jcifs.smb.SmbFile.connect0(SmbFile.java:797)
    at jcifs.smb.SmbFile.copyTo(SmbFile.java:2022)
    at copyToWindows.copyFile(copyToWindows.java:26)
    at copyToWindows.main(copyToWindows.java:14)

    at jcifs.smb.SmbTransport.negotiate(SmbTransport.java:947)
    at jcifs.smb.SmbTree.treeConnect(SmbTree.java:119)
    at jcifs.smb.SmbFile.connect(SmbFile.java:827)
    at jcifs.smb.SmbFile.connect0(SmbFile.java:797)
    at jcifs.smb.SmbFile.copyTo(SmbFile.java:2022)
    at copyToWindows.copyFile(copyToWindows.java:26)
    at copyToWindows.main(copyToWindows.java:14)

我可以遠程寫入文件。

String sharedFolder="tmp/share/text.txt";
        String path="smb://1.2.3.4/"+sharedFolder;
        NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("",user, pass);
        SmbFile smbFile = new SmbFile(path,auth);
        SmbFileOutputStream smbfos = new SmbFileOutputStream(smbFile);
    smbfos.write("TEsting ".getBytes());

確保您使用的是截至目前的最新jar，即jcifs-1.3.15.jar，而不是較低版本的jar，例如jcifs-1.1.11.jar等。
