现在的情况是c10已经配置为custom java provide，实现类似sdk的jdbcsample，但是用sdk取得passportid时一直是空
Cognos10获取PassPort要单独实现。代码如下

package com.cognos.common;
import java.net.MalformedURLException;
import java.rmi.RemoteException;
import org.apache.axis.AxisFault;

//密码

//名称空间
private String namespace = "lgtq1983";
//构造函数，通过配置文件得到服务器地址，名称空间，用户名和密码，并连接登陆cognos服务器
public CognosLog(String CM_URL, String username, String pwd,

this.CM_URL = CM_URL;

}
