SQL2000 installation and Setup of Java JDBC driver

1. First, remember to patch SQL2000 with SP3 or above (SP4 is recommended)
2. Install SQL Server 2000 driver for JDBC Service Pack 3

3. After installing SQL Server 2000 driver for JDBC Service Pack 3, it is installed in c: \ Program Files \ Microsoft SQL Server 2000 driver for JDBC by default, in C: \ Program Files \ Microsoft SQL Server 2000 driver for JDBC \ Lib contains three jar files:
Msbase. jar, MSSQLServer. jar, msutil. jar, remember to copy these three files to the JRE under your installed JDK. Here I will describe my installation Configuration:
My JDK is jdk1.5.0 _ 09, which is installed on:
In C: \ Program Files \ Java, there are two folders under the c: \ Program Files \ Java directory:
Jdk1.5.0 _ 09 directory and jre1.5.0 _ 09 directory,
The Three jar files mentioned above must be copied to the ext directory under the lib directory under the JRE directory under the jdk1.5.0 _ 09 directory. The complete path here is:
C: \ Program Files \ Java \ jdk1.5.0 _ 09 \ JRE \ Lib \ ext

 

 

4. Set classpath and add the Three jar files.

5. Set SQL2000 to mixed logon mode (Windows and SQL)
