title: Java Jar files not executing
body: <p>Not too long ago I asked a question about distribution of java jar files...that was perfectly answered and my jar files were completely working fine...but in a past few days they have stopped working directly by double clicking and i have to run it through the command java -jar .jar
  what could be the possible reason behind this...i mean i have already included the manifest file and the main classes have also been defined.... I have really no idea whats going on here!!
