Running jar file in cmd in Windows gives error

Question

I have downloaded a jar file called beagle.14Jan16.841.jar from here and am trying to run it in cmd using the line

java –Xmx8g –jar beagle.14Jan16.841.jar gt=beaglefilt.vcf out=beagleoutput

My cmd directory is the location of the beagle.14Jan16.841.jar file.

The error I get is Error: Could not find or load main class ?Xmx8g

My java is up to date and PATH leads to my java bin folder (java -version works).

The jar file is in my current cmd directory. Do I still need to add it to the class path? If so, how if the jar file is in C:\Users\Administrator\Documents\Research? — evoclue

Yes, you do. set classpath=%classpath%;.\beagle.14Jan16.841.jar. Do the same thing if it's somewhere else. Just include the full path — dragon66

Your Problem is in - character,in your error say it as ?

Try to copy this command and run it:

java –jar beagle.14Jan16.841.jar gt=beaglefilt.vcf out=beagleoutput

Then I get the error Error: Could not find or load main class ?jar

You're right about the character difference. I initially wrote it somewhere else and was trying to copy and paste it. Thank you.
