Unable to run java with an external library

Question

I saw this post but I wasn't clear on what the resolution was.

I'm trying to run a java program from command line utilizing an external library. Here is the total output of my session:

grifter@host:~/java$ cat ExtractTest.java 

import java.io.IOException;
import org.apache.pdfbox.util.PDFTextStripper;
import org.apache.pdfbox.pdmodel.PDDocument;
import java.io.File;

public class ExtractTest {

public static void main(String[] args) throws IOException {

    System.out.println("About to open PDF");
    File fh = new File("/home/grifter/test.pdf");
    PDDocument d = PDDocument.load(fh);
    System.out.println("Here");
    PDFTextStripper ts = new PDFTextStripper();
    System.out.println(ts.getText(d));

    }
}

grifter@host:~/java$ javac -cp .:/home/grifter/pdfbox-1.8.5/pdfbox/target/pdfbox-1.8.5.jar ExtractTest.java 
grifter@host:~/java$ java -classpath .:/home/grifter/pdfbox-1.8.5/pdfbox/target/pdfbox-1.8.5.jar ExtractTest

Could someone please point me in the right direction?

Any help is appreciated.

Answer 1

pdf box uses dependencies, which also needs to be added to your class path. You can read about the dependecies here

Answer 2

The jar commons-logging and the dependencies is missing in your classpath.

You can download it here
