i have a java program that uses Jre6 (for the Swing based GUI) but also jre1.2.2 (that Visibroker 45 needs to make CORBA API call). if i install jre 1.2.2 and then jdk6 (includs jre6) all is ok. but if after all is installed,
i re-install jre 1.2.2 the GUI program will not start when i click on the jar file. i have a simple workaround to the problem (i just run: 'javaw -jar <jar file name>' and make sure in Path env variable the bin directory of jre6 is the first in the list or run:'<full path of javaw.exe in jre6 bin dir> -jar <jar file name>') and these options work great, but still it's very annoying i can't just click on jar file after i re-installed jre 1.2.2. it's more annoying since this program is used by a lot of people and it takes me long time to explain to them how to use the workaround/s in case of conflict (which there are sometimes). i've tried to change the default javaw.exe file/process that files of .jar extension are started with and nothing worked. it's got to be some jre conflict but i don't know what and how to fix it.
