Some notes on the steps one needs to setup webservices etc. for a VO
  (somewhat linux RH9 centric)

Keep in mind that version numbers as well as overall flow of things you
do is likely to change as time goes on. This document was initially written
October 2003 and is evolving as the TVO demo evolves from simple
cgi-bin access to VO enabled webservices....

0) make sure your local webserver is running, i.e.

	mozilla http://localhost

   should now come back with either the silly default placeholder RH9 gives you, 
   or whatever you did. On RH9 you main page lives under

       /var/www/html/

   on this webserver machine..

1) java: you need a JDK. I used 1.4.2 , in the end, $JAVA_HOME will be used by other
   programs, and is used to point to where the JDK resides. I.e. JAVA_HOME/bin/java
   is normally where you find the java executable on linux.

2) apache w/ tomcat: if you get RH9, you get apache, but that's not enoguh. you
   need the java enabled thing, so you can choose either a new version, or 
   add the java stuff. So, go to 

		 http://jakarta.apache.org/site/binindex.cgi

   and get yourself the binary version, e.g. i found the file

		 jakarta-tomcat-5.0.12.tar.gz

   then untarred it, and ran

		 cd jakarta-tomcat-5.0.12
		 bin/startup.sh 
 
   and now tried the URL

	     http://localhost:8080/

   and voila, the tomcat server is now setup and running. Try running some
   examples to make sure it works.

   (curious point: i was able to startup the tomcat server as 'teuben' while
    normal apache was already running as 'apache')

3) axis 1.1, 
    Look in 
	 http://ws.apache.org/axis/index.html
    i downloaded
      axis-1_1.tar.gz
    then copy the axis-1_1/webapps/axis tree into the jakarta-tomcat-5.0.12/webapps/
    tree.

    restart the server
	    bin/shutdown.sh
	    bin/startup.sh

    and try the webpage
	    http://localhost:8080/axis/
    and see if you can validate yourself.


- then:
       a) take a java interface
       b) java2wsdl   
       c) wsdl2java, and fill in the template

  put these classes is then generates into axis/web.inf/classes    <as tree>
  or:						       /lib        <as jar>  ??

  then run some axis program to deploy this


? SOAP-Lite-latest.tar.gz
? XML-RPC

Mirage is a java application available from Lucent Technologies:
http://www.bell-labs.com/project/mirage/. It can do various forms of
visualization of tabular data, including spreadsheets, scatter plots,
histograms, and vector plots. One particularly nice feature is the
ability to select a subset of the data in one plot to see where the appear
in other plots.
