我目前正在尝试将 Web 服务合并到我的应用程序中。我无法访问 Web 服务本身，但可以通过 jar 文件访问。下面是访问 Web 服务的代码：
import java.util.List;
import java.io.Serializable;
import java.lang.String;
import com.zf.fileviewing.connection.FVConnectData;
import com.zf.fileviewing.connection.FVConnector;
import java.net.URL;
public class CheckOutAxalant implements Serializable
{
private static final long serialVersionUID = 1L;
public List<String> CheckoutAxalant(String docCid)
{
List<String> fileNames;
String userId="";
FVConnectData fvData = new FVConnectData();
fvData.setWsKeyword("");
fvData.setWsUrl("");
FVConnector con = new FVConnector(fvData);
// get all filenames of document
try
{
fileNames = con.getAllFileNames(docCid, userId);
for (String value : fileNames)
{
System.out.println("filename: " + value);
}
return fileNames;
}
catch (Exception e)
{
System.out.println("ERROR: " + e.getMessage());
e.printStackTrace();
return null;
}
}
错误发生在该行：
FVConnectData fvData = new FVConnectData();
完整的堆栈跟踪如下：

因为我无法访问网络服务，所以我非常坚持这一点。
另外仅供参考，如果我运行相同的代码但将其调整为普通的 Java 应用程序，它就没有问题。
