What I’m trying to do is running a .java source by compiling and running

  • 0

What I’m trying to do is running a .java source by compiling and running it from command prompt (not using any IDE) using commands javac and java and the program connects with MySQL, so everytime I run the program from cmd, I need to specify path of the MySQL connector using -classpath switch of java. And entire command to run the program gets something like below:

java -class .;path/to/connector/mysql-connector.jar MySQLConnect

where I want it to be as simple as for other programs like java MySQLConnect
and it should run the program.

Is there any way I can add the connector’s path to environment variables of Windows that java make use of it. I already tried by creating a new CLASSPATH variable in Windows environment variables and added absolute path of the connector with file name along, but that didn’t worked.

Please provide me the workaround of this Windows and Ubuntu as well.

Thanks.
