Follow the steps given below to invoke latest VOPlot-lite applet version through web-browser.

Instructions for Apache web server.

------------------------------------

1. Place the voplot jar files (voplot.jar + voplot_3rdParty folder) in the home directory (htdocs) of the web server. You can download the zip file of signed jars here.

2. Modify and place the perlscript (after unzipping) loadjvt file in the cgi-bin directory. You have to change the URL for voplot applet codebase and the prefix for the VOTable according to the settings of the server.

e.g. - If the voplot jar and the VOTables reside in the home directory (htdocs) of the Apache server, then assuming that the server listens to port 8080, you will have to modify the values of the following variables in the perlscript as,

$APPLET_CODEBASE="http://localhost:8080/"

$VOTABLE_PREFIX="http://localhost:8080/"

3. Modify and place the demo html page VOTables.html in the home directory (htdocs) of the web server. You will have to modify the prefix of the URL for the VOTables as mentioned earlier.

e.g. - If the VOTables reside in the home directory (htdocs) of the Apache server, then assuming that the server listens to port 8080, you will have to modify the prefix of the VOTable URL to "http://localhost:8080/".

You can view this html page through the web-browser by typing the URL "http://localhost:8080/VOTables.html".

1. Click on the link "plot" to view the plot of each VOTable in the web-browser. Please make sure that the VOTables are present in the proper location before plotting them.
