Java: Could not find or load main class

I developed a small Java program under windows and am now trying to run it on an ubuntu machine.

run.sh:

/opt/atlassian/jira/jre/bin/java -classpath "commons-lang3-3.3.2.jar;opencsv-3.3.jar;.\TisowareExportConverter.class" info.aptis.plakon.TisowareExportConverter /home/tisoware/transfer/tisoware_presence_export.csv /home/tisoware/convert/$

I compiled the .java file under windows

Directory contents

tisoware@server037:~/convert$ ls -la

    -rw-r--r-- 1 root         root           4425 Apr 19 14:21 TisowareExportConverter.class

The java class

package info.aptis.plakon;

public class TisowareExportConverter {

    public static void main (String[] args) { /* stuff is done here */}
}

Problem

All I get is

tisoware@server037:~/convert$ bash convert.sh
Fehler: Hauptklasse info.aptis.plakon.TisowareExportConverter konnte nicht gefunden oder geladen werden

(Translation: Could not find or load main class info.aptis.plakon.TisowareExportConverter)

What am I doing wrong?

Under Windows the program runs like this

run.bat

java -classpath libs\commons-lang3-3.3.2.jar;libs\opencsv-3.3.jar;out\production\tisowareExportConverter2 info.aptis.plakon.TisowareExportConverter tiso_infile.csv tiso_outfile.csv tiso_user_mapping.csv

Thank you, Internet <3
