I downloaded MapViewer from OTN some time ago. How do I find out which version it is?
First, scroll all the way to the bottom of the home/welcome page of your MapViewer instance. If you see a line like Build: Ver9_0_4_B030829, that’s the version and build number of your MapViewer instance. If you did not see such a line, chances are it is an older (pre 9.0.4) version of MapViewer. In any case, you can always navigate to the MapViewer’s unpacked directory $MAPVIEWER/web/WEB-INF/lib/, and find the file named mvclient.jar. Now run the command “jar tvf mvclient.jar” and it will display a list of class files packaged inside. One of the files will have a name like “Ver902_*.class”. This tells you the version and build number of your MapViewer instance.
