I have CQ5 executable jar file.It is suppose to be executed on double clicking.But i get error saying "could not find Main class program will exit".The same jar file executed on all my team mates machine but i am unable to execute it.

I am working on windows 7 OS. I have jre6 installed.

type of file on my system is "JAR" but on everyone else machine its "Executable JAR" Could not figure out what is problem with my system.

Answer 1

You can alternatively try executing this command from a command console, first CD to the location where you have the jar file and execute

For Win7 32-bit:

java -Xmx1024M -jar .jar

For Win7 64-bit:

java -XX:MaxPermSize=256m -Xmx1024M -jar .jar

if you have supported version of Java installed correctly, then the command should be able to start the CQ5 server. In that case, for fixing the double click issue, you would need to fix the filetype association of .jar files to open with /bin/javaw.exe

For supported Java versions, refer
