Doing the tutorial at ADASS

Most of the information you need for the tutorial will be available here before ADASS. Many of the examples use Apache AXIS. If you are intereested in trying to do get these working during the tutorial on you lap top you should install AXIS.
To actually get AXIS running you will need to set up your environment after you unzip it. You may create a script to do this. Here is the environment you need for simple AXIS client building (it's for DOS - you can convert for UNIX easily right ;):

set ALIB=C:\java\axis-1_1RC2\lib\

set CLASSPATH=.;c:\java;%ALIB%\axis-ant.jar;%ALIB%\axis.jar;%ALIB%\commons-discovery.jar;%ALIB%\commons-logging.jar;%ALIB%\saaj.jar;%ALIB%\axis.jar;%ALIB%\jaxrpc.jar;%ALIB%\wsdl4j.jar;%ALIB%\log4j-1.2.4.jar;

Notice this includes c:\java - it's a good idea to include some directory in the classpath which you will generate WebService stubs into.

Doing the grid-services bit

Grid services are more complicated than web services (they do more complicated things) and need more infrastructure to build and run than is described above. Materials for doing the grid-service tutorial on your own machine are available, including components for a sample service and its clients plus a list of supporting software that you would need to install.
