A simple implementation of a Java timer. Executes timer task every second.

Compare two dates in Java.

I actually like SQL. So, things like Hibernate with it's own query language don't quite fit my style. But, I don't want to code the same catch SQLException conn.close over and over either. So, I came up with this.

The idea is you extend SQLCommand (usually anonymously) override getSql(), and call execute() to get a list of whatever objects you are selecting - all the cleanup stuff is taken care of. It also handles nullable attributes more intuitively using ResultSetWrapper and PreparedStatementWrapper so that in your overridden getRow(ResultSetWrapper rs) method, you can call getInt on a nullable column and have it return null - what a concept! Also I like java.util.Date for my dates, so the wrappers convert to/from java.sql.Timestamp.

Right now I've only bothered with some basic types - it should be pretty clear how to add more if you need em.

See what ya'll think.

Oh, it uses JDK 1.5 Generics, but stripping that away would be pretty easy if you wanted 1.2 compliance.

I needed these for a recent project, bits and bytes constants.

Convert a password returned by JPasswordField::getPassword() into a String.

Add additional IP to compute

A utility class that gets the MD5 hash of an input stream. Also includes a method for converting byte array to hex-formatted string.

Read a eight bytes in little endian order from the given InputStream and create a long out of them.

Checks to see if a file or folder exists
The fFile variable determines whether you're
looking for a File (True) or Folder(False)
The strName variable holds the fully qualified
path you're looking For

this function returns the aggregated size
of all files in a directory and its subdirectories
