Using a java class from within Matlab

Hi all,

I am programming some metadata tools for NOAA's (National Oceanic and Atmospheric Administration's) hourly surface database, and I'm having trouble getting a java class they supplied to work within matlab.

I have no java experience at all and have never used Matlab apart from in this project, though I have been using it daily now for two months or so.

The java class comes as just a .class file (ish-Java.class), and it is used to turn the raw NOAA data files into a space-delimited text file. I can use it fine from windows command line when the .class and raw data are in the same directory. I cd to the directory in question and input simply:

java.ishJava (input filename) (output filename.txt)

Minus the parenthesis of course. My question is how can I do this from within Matlab? My code downloads necessary raw files over ftp, but I want to automate the conversion. I have tried adding the folder ishJava is in to the static java classpath, and Matlab recognizes ishJava, but I have no idea how to execute these methods from within Matlab. Any help would be appreciated.
