C# 动态调用java webservice的问题？？

现在动态调用从C#的 webservice代码能运行，但是调用java webservice就不行。
关键就是代码内红色地方，命名空间在java里没有命名空间，不知道怎么解决?
//动态调用web服务
public static object InvokeWebService(string url, string methodname, object[] args)
{
return WebServiceHelper.InvokeWebService(url, null, methodname, args);
}

public static object InvokeWebService(string url, string classname, string methodname, object[] args)
{
string @namespace = "EnterpriseServerBase.WebService.DynamicWebCalling";
if ((classname == null) || (classname == ""))
{
classname = WebServiceHelper.GetWsClassName(url);
}

try
{
////获取Web Service描述
WebClient wc = new WebClient();
Stream stream = wc.OpenRead(url + "?wsdl"); //一定要以?wsdl结尾
ServiceDescription sd = ServiceDescription.Read(stream);
ServiceDescriptionImporter sdi = new ServiceDescriptionImporter();
sdi.ProtocolName = "soap";
sdi.Style = ServiceDescriptionImportStyle.Client;
sdi.AddServiceDescription(sd, "", "");

//指定命名空间
CodeNamespace cn = new CodeNamespace(@namespace);

//生成客户端代理类代码
CodeCompileUnit ccu = new CodeCompileUnit();
ccu.Namespaces.Add(cn);
sdi.Import(cn, ccu);
//建立C#编译器
CSharpCodeProvider csc = new CSharpCodeProvider();
ICodeCompiler icc = csc.CreateCompiler();

//设定编译参数
CompilerParameters cplist = new CompilerParameters();
cplist.GenerateExecutable = false;
cplist.GenerateInMemory = true;
//添加编译条件
cplist.ReferencedAssemblies.Add("System.dll");
cplist.ReferencedAssemblies.Add("System.XML.dll");
cplist.ReferencedAssemblies.Add("System.Web.Services.dll");
cplist.ReferencedAssemblies.Add("System.Data.dll");

//编译代理类
CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu);
if (true == cr.Errors.HasErrors)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
foreach (System.CodeDom.Compiler.CompilerError ce in cr.Errors)
{
sb.Append(ce.ToString());
sb.Append(System.Environment.NewLine);
}
throw new Exception(sb.ToString());
}

//生成代理实例，并调用方法
//获取程序集
System.Reflection.Assembly assembly = cr.CompiledAssembly;

//获取程序集类型
Type t = assembly.GetType(@namespace + "." + classname, true, true);
object obj = Activator.CreateInstance(t);
//获取方法
System.Reflection.MethodInfo mi = t.GetMethod(methodname);
//调用方法
return mi.Invoke(obj, args);
}
catch (Exception ex)
{
throw new Exception(ex.InnerException.Message, new Exception(ex.InnerException.StackTrace));
}
}

private static string GetWsClassName(string wsUrl)
{
string[] parts = wsUrl.Split('/');
string[] pps = parts[parts.Length - 1].Split('.');

return pps[0];
}

}
