将 DB2 与 Java 连接起来
我需要将 DB2 与 Java 连接起来。请帮助我在 ECLIPSE 中将 DB2 与 java 连接起来。如果你能一步一步地指导我,那将是非常有帮助的 请让我知道如何在eclipse代码片段中添加类路径:
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;
public class connection {
public static void main(String[] argv) {
try {
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
}
catch (ClassNotFoundException e) {
System.out.println("Please include Classpath Where your DB2 Driver is located");
e.printStackTrace();
return;
}
System.out.println("DB2 driver is loaded successfully");
Connection conn = null;
PreparedStatement pstmt = null;
ResultSet rset=null;
boolean found=false;
try {
conn = DriverManager.getConnection("jdbc:db2:sabarish","db2admin","Murugasaranam");
if (conn != null)
{
System.out.println("DB2 Database Connected");
}
else
{
System.out.println("Db2 connection Failed ");
}
pstmt=conn.prepareStatement("Select * from bo");
rset=pstmt.executeQuery();
if(rset!=null)
{
while(rset.next())
{
found=true;
System.out.println("Class Code: "+rset.getString("clcode"));
System.out.println("Name: "+rset.getString("name"));
}
}
if (found ==false)
{
System.out.println("No Information Found");
}
} catch (SQLException e) {
System.out.println("DB2 Database connection Failed");
e.printStackTrace();
return;
}
}
}
在运行代码时,我得到了以下异常:
java.lang.ClassNotFoundException: COM.ibm.db2.jdbc.app.DB2Driver
