How to add external jar without Eclipse build path option?

问题

My java file jdbc11.java was compiled successfully with javac jdbc11.java command in cmd, after that when I tried to to run java jdbc11 I got this exception:

java.lang.ClassNotFoundException: com.mysql.jdbc:Driver

refering to this code in the file

Class.forName("com.mysql.jdbc.Driver");

, when I tried it in eclipse ,I added to "Java Build Path" the external jar : mysql-connector-java-5.1.20-bin.jar and it run successfully . in case I didn't fix it with eclipse what should I done in the first try with java jdbc11 command in order to make work ? note: the jar in the same dir with the jdbc11.java

Try adding the mysql-connector jar to the classpath when you execute your command-line code:

java -cp mysql-connector-java-5.1.20-bin.jar;. jdbc11

You have to add -classpath in the execute command

java -classpath mysql-connector-java-5.1.20-bin.jar jdbc11

If I'm understanding you allright, what you are missing is a -cp option in your java command line, which is what eclispe would do internally if you were to put it in the build path.
