Could not find the main class: SortAlgorithms

Question

I have this Java class:

public class SortAlgorithms {
public static void main(String... args) {

        String out = "";
        int vec1[] = readFile(args[0]);

        out = out + write(vec1);
        out = out + "=== INSERTION SORT ===\n";
        insertionSort(vec1, vec1.length);
        out = out + write(vec1) + "\n";
...
}
...
}

And I deploy it on other machine at my Boinc platform. There is a bash script to run this class:

#!/bin/sh

export JAVA_HOME="/usr/java/jdk1.6.0_34/"
export PATH=${JAVA_HOME}/bin:${PATH}

java SortAlgorithms 10 "output.txt" > saida.txt

And I receive this error:

<stderr_txt>

Does anyone know what is happening? Thnaks in advance. Felipe

Answer 1

Your class file was not copied properly. It starts with string '<sof' which is definitely not a java bytecode start.
