Re: [xsl] XSL + Java extensions + Xalan + banging my head ag

The specific error might help. I think from looking at your code that
the method, setIndent(), should be static. 

Did you consider that you are doing a lot of String construction?
Instead you could try:

  public static String setIndent(int indent)
  {
    char[] indents = new char[indent];
    java.util.Arrays.fill(indents, " "); // use for loop if ver < 1.2
    return new String(indents);
  }
