连接 oracle 11g 与 java 8 (eclipse)

Question

I can't import java.sql.*; because it said that this package is not accessible although I put ojdbc6 and also I tried ojdbc8 in the classpath but it isn't work; [ I mention that I have oracle 11g and jdk 10 & eclipse 4 ]

Answer 1

How did you add your ojdbc driver? A typical way is shown below:

First you need to right click your project and go for "Build Path" and go for "Configure build Path"

Then, in the "libraries" tab, click on the "Add External JARs" go to your ojdbc driver file to load it.

This is the typical way to load your ojdbc driver. Try first see whether it will help

Answer 2

If your IDE (Eclipse) gives error:

The package java.sql is not accessible

Or if compiling using javac gives error:

test\Test.java:3: error: package java.sql is not visible
import java.sql.*;
           ^
  (package java.sql is declared in module java.sql, but module Test does not read it)
1 error

Then it is because your Java 9+ project has a module-info.java file, ie your project is modular .

You need to add the following line to the module-info.java file:

    requires java.sql;
