Could not find or load main class when trying to use ojdbc

Question

I'm using code and compiling command from this question (just replaced DBConnect by Test). Then I use java -classpath ojdbc14.jar Test and I'm getting: Error: Could not find or load main class Test.

Same for: java -classpath "ojdbc14.jar;." Test and java -classpath "ojdbc14.jar;./Test.class" Test

When I use just java Test then the error is

Exception in thread "main" java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver
        at Test.main(Test.java:7)
Caused by: java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

@KaustubhKhare since using `-cp` flag is overwriting default value which is current directory, I added it there — pikkewyn, Apr 12 '18 at 10:03
On linux you need to separate classpath entries using `:`, not `;`, and you don't need to surround it with quotes — Mark Rotteveel, Apr 12 '18 at 10:08
@MarkRotteveel, thanks, I don't know how I managed to miss it. Problem solved — pikkewyn, Apr 12 '18 at 10:13

Try doing this,

Set the class path first and then compile and run the program.

classpath=%classpath%;ojdbc14.jar(path for your OJDBC jar);
javac Test.java
java Test
