There are thousands of materials on the internet. I followed some of the trusted sources but still I'm getting this error:
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
I'll quickly show you what I've tried:
Added classpath in environment variables
Then I tried adding with command prompt also with this command:
set classpath=%classpath%;C:Users\\320050772\\Documents\\task-tracker\\*.jar
But still I'm getting this error:
Either I'm not doing this correctly or I'm missing an important step here. Please correct me.
Here's is my DataService.java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class DataService {
public static void main(String args[]){
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con=DriverManager.getConnection(
"jdbc:oracle:thin:@localhost:1521:xe","system","scott");
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from emp");
while(rs.next())
System.out.println(rs.getInt(1)+" "+rs.getString(2));
con.close();
}
catch(Exception e){
System.out.println(e);
}
}
}
From the java docs:
Class path entries that are neither directories nor archives (.zip or JAR files) nor the asterisk (*) wildcard character are ignored.
My advise is to replace "*.jar" with concrete .jar - File references. Please double check the output of echo %CLASSPATH%
(Windows) or echo $CLASSPATH
(Linux and related OS)
