连sqlserver 出错

连sqlserver 出错。我下载的 SQLServer 2000 Driver for JDBC sp1. 执行任何sql语句出错。
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]对象名 'lucker' 无效。 at com.microsoft.jdbc.base.BaseExceptions.createException(Unknown Source) at com.microsoft.jdbc.base.BaseExceptions.getException(Unknown Source) at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processErrorToken(Unknown Source) at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processReplyToken(Unknown Source) at com.microsoft.jdbc.sqlserver.tds.TDSExecuteRequest.processReplyToken(Unknown Source) at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processReply(Unknown Source) at com.microsoft.jdbc.sqlserver.SQLServerImplStatement.getNextResultType(Unknown Source) at com.microsoft.jdbc.base.BaseStatement.commonTransitionToState(Unknown Source) at com.microsoft.jdbc.base.BaseStatement.postImplExecute(Unknown Source) at com.microsoft.jdbc.base.BaseStatement.commonExecute(Unknown Source) at com.microsoft.jdbc.base.BaseStatement.executeQueryInternal(Unknown Source) at com.microsoft.jdbc.base.BaseStatement.executeQuery(Unknown Source) at _jspdocs._test._jspService(_test.java:70) at oracle.jsp.runtime.HttpJsp.service(HttpJsp.java) at oracle.jsp.app.JspApplication.dispatchRequest(JspApplication.java) at oracle.jsp.JspServlet.doDispatch(JspServlet.java) at oracle.jsp.JspServlet.internalService(JspServlet.java) at oracle.jsp.JspServlet.service(JspServlet.java) at javax.servlet.http.HttpServlet.service(HttpServlet.java:588) at org.apache.jserv.JServConnection.processRequest(JServConnection.java) at org.apache.jserv.JServConnection.run(JServConnection.java) at java.lang.Thread.run(Thread.java:479)

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"); 
Connection conn = DriverManager.getConnection 
  ("jdbc:microsoft:sqlserver://server1:1433;User=test;Password=secret"); 
里面没有数据库的名字，所以程序不知道你要找哪张表里的数据
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
conn=DriverManager.getConnection("jdbc:Microsoft:sqlserver://server1:1433;DatabaseName=数据库名；User=test;Password=secret");
