Running PhantomJS from inside a Jar

Question

I use PhantomJS to do silently testing a website. Since it exewill be attached to the file jar, I decided to read it and write to a temporary file so that I can normally get it through the absolute path.

Here's the code to convert InputStreamto String, referencing the new temporary file:

public String getFilePath(InputStream inputStream, String fileName)
        throws IOException
{
    String fileContents = readFileToString(inputStream);
    File file = createTemporaryFile(fileName);
    String filePath = file.getAbsolutePath();
    writeStringToFile(fileContents, filePath);

    return file.getAbsolutePath();
}

private void writeStringToFile(String text, String filePath)
        throws FileNotFoundException
{
    PrintWriter fileWriter = new PrintWriter(filePath);

    fileWriter.print(text);
    fileWriter.close();
}

private File createTemporaryFile(String fileName)
{
    String tempoaryFileDirectory = System.getProperty("java.io.tmpdir");
    File temporaryFile = new File(tempoaryFileDirectory + File.separator
            + fileName);

    return temporaryFile;
}

private String readFileToString(InputStream inputStream)
        throws UnsupportedEncodingException, IOException
{
    StringBuilder inputStringBuilder = new StringBuilder();
    BufferedReader bufferedReader = new BufferedReader(
            new InputStreamReader(inputStream, "UTF-8"));

    String line;
    while ((line = bufferedReader.readLine()) != null)
    {
        inputStringBuilder.append(line);
        inputStringBuilder.append(System.lineSeparator());
    }

    String fileContents = inputStringBuilder.toString();

    return fileContents;
}

This works, but when I try to start PhantomJS, it will give me ExecuteException:

SERVERE: org.apache.commons.exec.ExecuteException: Execution failed (Exit value: -559038737. Caused by java.io.IOException: Cannot run program "C:\Users\%USERPROFILE%\AppData\Local\Temp\phantomjs.exe" (in directory "."): CreateProcess error=216, the version of %1 is not compatible with this Windows version. Check the system information of your computer and talk to the distributor of this software)

If I'm not trying to read PhantomJSfrom jar, therefore, using a relative path, it works fine. The question is how can I read and execute PhantomJSfrom a jar file, or at least a workaround when reading and writing a new (temporary) file for work.

    java.nio.file.Path p = java.nio.file.Files.createTempFile(prefix, suffix);
    p.toFile().deleteOnExit();
    java.nio.file.Files.copy(inputStream, p, java.nio.file.StandardCopyOption.REPLACE_EXISTING);
    return p.toAbsolutePath().toString();
