Parsing Headache - Please Help

Here's the problem. I need to cutoff any text to the right of and including the following words: "1CFP", "CFP", "1TNK", "TNK", "1AL1", "Al1", "1ATC", "ATC", "1WBL", "WBL", "1SHP", "SHP". (See full text below.) The constraint is that I cannot use methods or packages from Java 1.4, just 1.3. This means no regex and no strObj.split(param). (I used the latter successfully to cutoff the text, but then found out that it had to be compatible with version 1.3). I've tried a few approaches with no success. I must admit, my problem is with the logic. So I'm hoping that someone could give me some pointers. I'd really appreciate it.

Maybe something like this:

public class TruncateString {
    private String[] ends;
    public TruncateString(String[] ends) {
        this.ends = ends;
    }
    public String truncate(String src) {
        String ret = new String(src);
        for (int i = 0; i < ends.length; i++) {
            int index = src.indexOf(ends[i]);
            if (index != -1) {
                return src.substring(0, index);
            }
        }
        return new String(src);
    }
    public static void main(String[] args) {
        String[] ends = {"1CFP", "CFP", "1TNK", "TNK", "1AL1", "Al1", "1ATC",
                          "ATC", "1WBL", "WBL", "1SHP", "SHP"};
        String[] lines = {"L4W2E", "RG  2251 01 SBGL SBGR", "SENT TO: /RGX35",
                          "---------------------------------------------------------------------------",
                          "                                                                           ",
                          "                                                                      1CFP",
                          "RG002163 FMC B733 B727 B767 DC10 MD11 B777                            CFP"};
        TruncateString ts = new TruncateString(ends);
        for (int i = 0; i < lines.length; i++) {
            System.out.println(ts.truncate(lines[i]));
        }
    }
}

Here's the output:

I think what I can do is grab the character length of each row. If it's greater than 69, then I'll grab a substring from 0 to 69. If not, then don't grab a substring.
