FastDFS java 客户端上传文件错误

wp00000008

TrackerGroup tg = new TrackerGroup(new InetSocketAddress[]{new InetSocketAddress("192.168.100.68", 22122)});               
                                TrackerClient tc = new TrackerClient(tg);       
                                TrackerServer ts = tc.getConnection();       
                                StorageServer ss = tc.getStoreStorage(ts);
                                StorageClient1 sc1 = new StorageClient1(ts, ss);
                               
                                fileid = sc1.upload_file1("c:/a.txt", "txt", meta_list); //此行异常
                               
                                System.out.println("Upload local file "+item+" ok, fileid="+fileid);

以上是代码片段，上传出现java.net.ConnectException: Connection refused: connect异常
服务器tracker和storage正常运行，检查storage日志，无状况。
检查tracker日志，信息如下：

以上是代码片段，上传出现java.net.ConnectException: Connection refused: connect异常

定位一下是哪行代码引起的这个错误呢？
看出错信息，应该是连接服务器失败。

wp00000008

fileid = sc1.upload_file1("c:/a.txt", "txt", meta_list); //此行异常

以上代码行出问题

如果是连接服务器失败，那服务器日志里面是不会有
send data fail, errno
之类的信息的

我想问题应该是连接上了，可是在处理上传的时候，出现了问题

能否使用如下的形式，将出现异常时的调用堆栈打印出来呢：
                try
                {
                         //访问FastDFS的若干行代码
                }
                catch(Exception ex)
                {
                        ex.printStackTrace();
                }

看打印出来的异常信息，是连接storage server失败。

wp00000008

我找出原因了，将storage的配置文件修改了一下

从
tracker_server=127.0.0.1:22122
改为
tracker_server=192.168.100.68:22122

现在错误是：

java.lang.NullPointerException

        at org.csource.fastdfs.StorageClient.do_upload_file(StorageClient.java:407)

特别说明：
tracker和storage是在一台机器的
从客户机均能telnet上去

昨天我用你的测试代码测试过，碰到的也是NullPointer的异常。
FastDFS Java Client API中有全局变量需要初始化，你要先调用：
ClientGlobal.init(fdfs_client_conf_filename);

或者直接对ClientGlobal的全局变量进行赋值也是可以的。

多谢帮助，这个问题解决了。
