String.format equivalent in Java 1.4

Currently i have a method calling String.format() in Java 5 and it's working perfectly

String.format("%02x", octet) //octet is a int type

However due to some issue we need to deploy this code in a JDK 1.4 environment, and String.format doesn't exists in 1.4.

Anyone knows any alternative way to perform this function?

I think you should take a look at Retroweaver which lets you deploy Java 1.5 on a 1.4 JVM.

You could use something like this snippet: 

String hexString = Integer.toHexString(octet);
if (hexString.length() < 2) {
    hexString = "0" + hexString;
}

You need to use Integer.toHexString(int) and pad the text yourself.
