This document describes how to create an ecogrid web service and 
implement the functionality in Metacat.

Create the WSDL and WSDD
-- Create a new wsdl in seek/projects/ecogrid/src/xsd.  It's probably
   easiest to copy an existing one. And modify it.
-- Add the service to seek/projects/ecogrid/lib/server-config.wsdd

Build Stubs - for testing purposes, you can follow these steps to build
the stubs and service in seek.  They are also build when you do a full
build of Metacat, but it's much easier to shake out issues here first.
-- In your project, include the following libraries:
	-- seek/projects/ecogrid/lsid/lib/*.jar
	-- seek/projects/ecogrid/lib/*.jar
-- Create a new build file in seek/projects/ecogrid/buildfiles/.  It's easiest
   to copy an existing one and change references to your service.
-- add your service to the target section in seek/projects/ecogrid/build.properites.
   Make sure your service is the only uncommented target.
-- add your service to seek/projects/ecogrid/lib/namespace2package.mappings
-- add your service to the compileTest target in: 
   seek/projects/ecogrid/buildfiles/base.xml
-- create a build<service_name>, deploy<service_name> and test<service_name> targets 
   in seek/projects/ecogrid/buildfiles/metacatImpl.xml 
-- add build<service_name> to war target dependencies.
-- in seek/projects/ecogrid/build.xml, run the stubJar target

Create the metacat implementation
-- create a file named: 
   seek/projects/ecogrid/src/org/ecoinformatics/ecogrid/metacat/<your_dir>/Metacat<your_service>Impl.java
	
Modify metacat and the metacat client - if your service requires changes to metacat 
or the metacat client, you should follow these steps:
-- make your changes to metacat 
-- build metacat to generate a new metacat.jar and metacat-client.jar.  Use 
   "ant clean jar" and "ant clean clientjar" to just build jar files.
-- copy metacat/build/metacat.jar to seek/projects/ecogrid/lib/
-- copy metacat/build/metacat-client.jar to seek/projects/ecogrid/lib/
-- make sure both jar files are included in your project library path
	
Build the ecogrid service
-- Include the newly generated stub jar file for your service in the project.
   library path.  The file will be in 
   seek/projects/ecogrid/build/lib/org.ecoinformatics.ecogrid.<your_service>-stub.jar
-- in seek/projects/ecogrid/build.xml, run the serverJar target
-- once this builds, you know the new service compiles.  It's time to build metacat
   to see if it runs.
   
Run Service in metacat
-- do an installation build of metacat
-- start metacat
