Jar file doesn't work on the web server

Question

I have an Jar file that is working perfectly fine on my Mac using console:

 MacBook-Pro-Pavel:PDFparser pavelpigalev$ java -jar PDFparser.jar
 Usage: java PDFparser <input-pdf> -p1 <password> -c1 -i0 -s1
    -p1 : PDF password
    -c1 : write JSON to console
    -i0 : don't extract images
    -s1 : take page screenshots [WARNING: currently in beta]
 MacBook-Pro-Pavel:PDFparser pavelpigalev$ java -jar PDFparser.jar f5.pdf
 MacBook-Pro-Pavel:PDFparser pavelpigalev$ 

It creates a folder and puts out images that I need in that folder.

But if I use it on the web server (also using console) it gives me this error:

 [root@somesite.com pdfparser]$ ls
ffive.pdf  lib  PDFparser.jar  README.TXT
[root@somesite.com pdfparser]$ java -jar "PDFparser.jar"
Usage: java PDFparser <input-pdf> -p1 <password> -c1 -i0 -s1

    -i0 : don't extract images
    -s1 : take page screenshots [WARNING: currently in beta]
[root@somesite.com pdfparser]$ java -jar "PDFparser.jar" ffive.pdf

I didn't make this Jar file, I don't really know much about Java. I work with PHP and I really need this program working well on server. Can someone help me with that?

Answer 1

Place vechmath .jar in your class path

Or - Add your supporting .jar s to the classpath

export CLASSPATH=$CLASSPATH:/path/to/vecmath.jar

Or - Supply at the Runtime

java -cp vecmath-xxx.jar -jar Yourjar.jar

Importance of Classpath

Answer 2

You're not using the same JVM that the one in your macbook. You're using GNU JVM as seen in not found in gnu.gcj.runtime.SystemClassLoader

Try a java -version to confim that and then change your JVM

Answer 3

Try to find vecmath-1.3.1.jar file on you Mac and place it in the same dir as PDFparser.jar is located. Try to run. If no success then try to run as follow:

 java -cp vecmath-1.3.1.jar -jar "PDFparser.jar"
