weblogic的EJB调试的问题？

meteor709414

我在weblogic中配置了JDBC和数据源，其中JNDI名称为erp。我在JB中写了一个测试连接的代码如下：
package test1;
import java.sql.*;
import javax.naming.*;
import javax.sql.*;
import java.util.Properties;
import javax.rmi.PortableRemoteObject;
public class Untitled1 {
  public Untitled1() {
  }

  public static void main(String[] args) {
    DataSource ds=null;
    Context ctx=null;
    Connection myConn=null;
    try{
      /**
       * 获得weblogic server JNDI 初始上下文信息
       */
      ctx=getInitialContext();
      /**
       * 建立数据源对象
       */
      ds=(javax.sql.DataSource)ctx.lookup("erp";
      }catch(Exception e){
        System.out.println("Init Error:"+e);
      }
   Statement myStatement=null;
   ResultSet myResultSet=null;
   try{
     /**
      * 建立连接
      */
     myConn=ds.getConnection();
     /**
      * 建立语句对象
      */
     myStatement=myConn.createStatement();
     String str="select * from users";
     /**
      * 建立结果集对象
      */
     myResultSet=myStatement.executeQuery(str);
     /**
      * 篇历结果集对象，访问每条记录，输出字段
      */
     while(myResultSet.next()){
       System.out.println("the users name is"+myResultSet.getString(2));
     }
     //关闭结果集
     myResultSet.close();
     }catch(SQLException e){
       System.out.println("Error code="+e.getErrorCode());
       System.out.println("Error message="+e.getMessage());
     }finally{
       try{
         //关闭语句对象
         if(myStatement!=null){
           myStatement.close();
         }
         //关闭连接
         if(myConn!=null){
           myConn.close();
         }
       }catch(SQLException e){
         System.out.println("Error code="+e.getErrorCode());
         System.out.println("Error message="+e.getMessage());
       }
     }
  }
  private static Context getInitialContext() throws Exception{
    String url="t3://localhost:7001";
    String user="sa";
    String password="jpzhang28";
    Properties properties=null;
    try{
      properties=new Properties();
      properties.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory";
      properties.put(Context.PROVIDER_URL,url);
      if(user!=null){
        properties.put(Context.SECURITY_PRINCIPAL, user);
        properties.put(Context.SECURITY_CREDENTIALS,password==null ? "" : password);
      }
      return new InitialContext(properties);
    }catch(Exception e){
      throw e;
    }
  }
}
在JB中运行时提示这样的错误：D:\bea\jdk142_04\bin\javaw -classpath "C:\Borland\JBuilder2005\jdk1.4\jre\lib\rt.jar;D:\bea\weblogic81\server\lib\weblogic_sp.jar;D:\bea\weblogic81\server\lib\weblogic.jar;D:\bea\weblogic81\server\lib\webservices.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msbase.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\mssqlserver.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msutil.jar;D:/bea/jdk142_04/lib/tools.jar;"   -ms64m -mx64m -Djava.library.path="D:/bea/weblogic81/server/bin" -Dbea.home="D:/bea" -Dweblogic.Name=myserver -Djava.security.policy=="D:/bea/weblogic81/server/lib/weblogic.policy" -Dweblogic.management.discover=false -Dweblogic.ProductionModeEnabled=false -Dweblogic.management.password=JPZHANG28 -Dweblogic.management.username=system weblogic.Server
