Question

I am trying to do "javac Classname.java" from cmd prompt, and this Classname.java requires Jfreechart libraries/jars, and runs fine if compiled from Eclipse (because project package has jars imported).

But I want to run the file from cmd prompt and its not able to show me the output. It comes with errors like: ("package doesn’t exist"), how to fix it? I need the class file and also run JNI commands to create header file.

You need to set the classpath.

You can do this in 2 ways. Either use the -classpath or -cp option:

javac -cp jar1.jar;path/to/jar2.jar Classname.java

Or, if you need it to persist, use the CLASSPATH environmental variable:

set CLASSPATH=path1;path2
javac Classname.java
