Hi... I have created a executable jar file. If I double click on this jar file it works fine with 32 bit JRE. But If I use 64 bit JRE, it is recognized as a jar file. If I double click on it, a window is shown to select a program for running the jar file. But it doesn't even work if I browse th java.exe or javaw.exe for running the jar file. Please tell me why 64 bit JRE does not recognizes it as a executable jar file, while it works fine with 32 bit JRE. One more thing, my JAR file always work from command prompt(java -jar jar_file) wheather I use JRE 32 or JRE 64 bit. Thanks
