Howdy. Code:bash-5.0$ java -jar download/GeoMapApp.jar

at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:482I have openjre7-7u251_b02-x86_64-1alien, & GeoMapApp-3.6.10 on Slackware64-Current. I get the same error with the -client or -server options. GeoMapApp-3.6.8 did the same thing. Can I get out of this with options, do I need openjdk, or sun's offering?
