You can run your test as:
./jmeter -Jjmeter.save.saveservice.output_format=xml -Jjmeter.save.saveservice.response_data=true -Jjmeter.save.saveservice.samplerData=true -Jjmeter.save.saveservice.requestHeaders=true -Jjmeter.save.saveservice.url=true -Jjmeter.save.saveservice.responseHeaders=true -n -t requests.jmx -l log.jtl
Alternatively you can add the next lines to user.properties file (lives in "bin" folder of your JMeter installation)
jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data=true
jmeter.save.saveservice.samplerData=true
jmeter.save.saveservice.requestHeaders=true
jmeter.save.saveservice.url=true
jmeter.save.saveservice.responseHeaders=true
This way JMeter will store results in a way they could be examined in the View Results Tree listener.
