How to call testng file using shell command in Jenkins?

I am new to Jenkins. I have installed Jenkins on Linux server & created a new Job, trying to execute the job with Shell Command. I have used following shell command to call testng.xml present in the workspace. My shell command is java -cp ./lib/*:./bin org.testng.TestNG testng.xml. Whenever I am trying to build it's got failure & Jenkins console output is given below...

Earlier I run same source file using Eclipse IDE & Jenkins installed in windows machine. Both Succeeded & No problem. But Jenkins installed in linux machine causes the problem.. How to solve this? Is there is any mistake in Shell Command that i have written above? I am facing this issue from last two days but didn't get any solution.. Please help on this..
