这真让我感到压力。我尝试在Pentaho和数据库SQL Server 2000之间建立连接这么多次。每次我尝试使用Native（JDBC）访问进行连接时，总会出现此错误：
Code:
Error connecting to database [sutera] : org.pentaho.di.core.exception.KettleDatabaseException:
Error occured while trying to connect to the database
Error connecting to database: (using class com.microsoft.sqlserver.jdbc.SQLServerDriver)
Java Runtime Environment (JRE) version 1.7 is not supported by this driver. Use the sqljdbc4.jar class library, which provides support for JDBC 4.0.

我搜索我收到此错误的原因以及我发现我认为可能导致此问题的原因是因为我的Java运行时环境（JRE）版本1.7。从我做的研究来看，这个Java版本无法读取我使用的jdbc驱动程序。所以我下载其他jdbc驱动程序，我认为它适合sql server 2000.但同样的错误仍然出来。所以，我改变了我的计划。我尝试将我的JRE更改为其他版本。但问题是，即使我已经将JRE更改为其他版本，它仍会检测到相同的版本，每次测试连接时仍会出现相同的错误。
请有人指导我如何删除此错误？我是Pentaho＆amp;的新手。面对这样的事情，我不知道如何解决它。
