     This file covers deploying the gwt created ajax code and servlet to a non-google
     version of tomcat.  This allows for the installation of the servlet(s) along
     side a normal metacat installation.  This file assumes you've already done
     the steps highlighted in the README file.
 ) Create a servlet on your tomcat instance called "rpc".  This is a simple servlet that just runs the gogle remote procedure call (rpc) services.  Use the web.xml file from the ./tomcat/webapps/ROOT/WEB-INF directory.  You'll also need to copy all of the gwt jar files from your gwt installation as well as all of the jar files in ./lib

     also need to copy all of the gwt jar files from your gwt installation as well
     as all of the jar files in ./lib.  Use the gwt-user.jar and gwt-dev.jar from
     metacat/lib.  If you use the ones from the gwt distro, tomcat won't load them
     due to the presence of javax.servlet.Servlet.
 ) copy ./src/org/kepler/web/service/KeplerServiceServlet.java to metacat/src/org/kepler/web/service/ and update the KeplerServiceServlet.java file with the correct url to your metacat servlet (line 6 in the code).
 ) copy ./src/org/kepler/web/service/KeplerServiceServlet.java to
     metacat/src/org/kepler/web/service/ and update the KeplerServiceServlet.java
     Edit the file with the correct url to your metacat servlet (line 6 in the code).
     Make sure the moduleRelativeURL exactly matches the url that will be browsed
     to!  I.E. Don't use "localhost" if you intend to browse to an actual machine
     name.  This confuses the RPC and will cause problems.
 ) run 'ant package' (from the ajax dir) and copy the newly created kepler-web.jar file to metacat/lib/
 ) run 'ant package' (from the ajax dir) and copy the newly created
     kepler-web.jar file to metacat/lib/.  Make sure you updated the hard coded
     servlet paths in the java code before doing this.
 ) run 'ant install' from your metacat directory
 ) make sure tomcat restarts
 ) run ./KeplerClient-compile and copy the contents of the www directory to some web accessible location, then browse to the KeplerClient.html file and the javascript should run.  Note that you may need to update any hard coded servlet paths in the ajax code before copying the www files to the web location.

     They are:
     * the rpc servlet
     * the KeplerServiceServlet servlet.  In the web.xml file, I have called this 'gwt' so the address will be: http://server:8080/servletpath/gwt

     Setup
     -----
 ) Make sure you have the google web toolkit installed.  You can get it from http://code.google.com/webtoolkit/.  From now on, I will refer to the google web toolkit directory as the "gwt" directory.
 ) Make a symbolic link in the gwt directory so that gwt-dev.jar -> gwt-dev-xxx.jar where xxx is either "mac", "linux" or "windows".  This just makes the scripting easier to deal with.
 ) Edit the KeplerClient-shell file and make sure $GWT points to your gwt installation.  Do the same for KeplerClient-compile

     Building
     --------
     Run the KeplerClient-shell script.  Upon successful compilation, you should see two windows open.  One is the tomcat server shell, the other is a test browser where you will see the web page.

     Testing
     -------
     You can use the -shell file for incremental building and testing.  If you want to "clean" the project, you can use the ant build.xml file.  The build file really is not needed.

     Installation/Deployment
     -----------------------
     Once you have a working product and you want to deploy to a normal instance of Tomcat, you can first test that your code works under a normal browser by clicking the "compile/test" button on the google browser.  This will open your page in whatever your default browswer is.  Your server side code is still running on the google tomcat instance (port 8888).  If you want to deploy the servlet and client side code to another instance of Tomcat, follow the instructions in the INSTALL file.

     A note on using different OSs
     -----------------------------
     There are a few differences when moving between windows, linux and osx.  On OSX, the -XstartOnFirstThread flag must be set in the KeplerClient-shell and KeplerClient-compile scripts.  Also, make sure you make a symlink for the gwt-dev jar file.  For some reason, google renames this jar depending on what system you download gwt for.
