Could not find or load main class Mysql

Question

I have problem with my java app compilation.

Folder structure:

src/LogServer.java (this is the main class)

src/SocketThread.java

I also use MySQL driver in it. This files aren't in package.

When I'm running:

javac -classpath mysql-connector-java-3.1.14-bin.jar *.java

everything works fine.

See the compilation:

java -classpath mysql-connector-java-3.1.14-bin.jar LogServer

compiler says:

user@user-Inspiron-3543:~/workspace/LogServer/src$ javac -classpath mysql-connector-java-3.1.14-bin.jar *.java

user@user-Inspiron-3543:~/workspace/LogServer/src$ java -classpath mysql-connector-java-3.1.14-bin.jar LogServer
Error: Could not find or load main class LogServer

Answer 1

You will need to use the -classpath argument. In your classpath, you will need '.' to establish that your current directory is on the classpath and the mysql-connector-java-3.1.14-bin.jar. So you put those two together in a list. On Linux, the elements are separated by ':'. On Windows, it is ';'.

java -classpath .:mysql-connector-java-3.1.14-bin.jar LogServer
