Here’s how to do a simple XSLT transformation using only classes in vanilla Java 1.5 (maybe even 1.4?), no external libraries or anything. The classes are found in the javax.xml.transform package.
Needed something to generate random passwords and found Java Password Generator. It generates passwords which are gibberish, but still sort of readable, which I think is a lot nicer than pure gibberish.
I just wanted a simple ‘get me a new random password method’ though, and not all the applet and ‘make several passwords’ stuff. Decided to extract the useful parts and clean it up a bit. In case I need it again, or others need it, and since he states “share your source with others freely”, here is the result 🙂
Wanted to create an easy interface for reading lines from a stream. It should take care of all the annoying Java IO nitty-gritty for me and I wanted to use it simply by throwing it into a for loop.
Ok, so I was happily reading CSV files from an SFTP server. The file content is returned as an InputStream and I I used a BufferedReader to read it line by line. Each line contained either a header or an order. The header lines started with the string “HDR”.
However, I suddenly discovered that my code was consistently skipping the first header (and as a result the orders belonging to it). The reason, I found, was simple. The first header, on the first line, didn’t start with “HDR”, it started with “â–¡HDR”! And that undisplayable square turned out to be a Unicode Byte Order Mark (BOM).
