Jenkins not starting as a windows service -

i have followed steps run jenkins window service . followed url : https://wiki.jenkins-ci.org/display/jenkins/installing+jenkins+as+a+windows+service

but jenkins not starting window service. when did research found problem following jenkins.xml file.

attached image.jenkins.xml snapshot

when change java keyword specific jdk path (c:\program files\java\jdk1.8.0_60\bin\java.exe) works without jenkins service not started.

so wanted know exact meaning of java word inside executable tag?

if executable tag contains word 'java' java expected in path system variable.

so if open command prompt , type 'java', should launch java. if doesn't java isn't on path , have specify full path executable, or alternatively add java path.

googling "add path windows" gives plenty of instructions on how this.
