Running a Java Program

Question

I looked at some other SO questions, didn\'t find anything that solved my problem... I have a Main.java file (below) and a OthelloLib.jar file without associated source files.

Answer 1

Note: You can do all this within a good IDE like eclipse or netbeans by adding the library to your project. The rest gets handled automagically.

Answer 2

Did you import all the libraries?

like

import a.b.c. OthelloPlayer;

Answer 3

Did you specify the classpath when you call your program?

Something like the following might work:

java -cp .:OthelloLib.jar Main

Answer 4

You run

javac -classpath .:OthelloLib.jar Main.java

to compile, then

java -classpath .:OthelloLib.jar Main

In each case the -classpath .:OthelloLib.jar option tells Java where to find SimplePlayer and other classes you need; it doesn't know to look in the JAR file on its own. And you do need to tell both the compiler and the virtual machine where to look for the classes.

EDIT: Looks like you added something about TimeoutException since I wrote this... did you remember to compile TimeoutException.java? And is the TimeoutException.class file in the same directory as Main.class?

Answer 5

Have you set a reference to OthelloLib.jar or invoking the javacompiler with the library as a parameter?

java -classpath .:OthelloLib.jar -g Main
