Windows XP and Windows 2000 + executable jar files

Hi All,

I have an java application which is zipped in a executable jar file. The application starts and works fine when the jar file is double clicked in windows 98 environment. But when I try to execute the same jar file on windows 2000 or windows xp by double clicking the jar file it doesn't starts. But i can start the application in windows xp and windows 2000 by the following command from the command prompt:

java -jar myapp.jar

Y cannot i execute the file by double clicking it unlike in windows 98.

Regards

Apparently .jar files are not associated with the java executable. You can check in Windows Explorer - Tools - Folder Options - File Types

i have found some files dont extract well on ntfs, mostly self extracting, to solve the problem i usually make a small fat32 partition on my machines to extract and start installations from, if they dont seem to run from ntfs. but have run into the opposite also, on windows 98 and ME have found that some files when extracted dont work right or at all, wordpad documents are blank on 98 and ME, but on a ntfs machine they have all thier info.
