How to get value extracted from regular expression extractor in Jmeter?

I get the following response from server in JSON: 

{
"global_id": 00001,
"name": "IMG_0747.JPG",  
"time_taken":   {  
"segment_1_time": 1,
"segment_2_time": 1,  
"segment_3_time": 27,  
"segment_4_time": 1,  
"segment_5_time": 16,  
"segment_6_time": 20,  
 }  
}

I want to extract the values of segment_1_time, segment_2_time,....,segment_6_time. To do so, I am using the following values in Regular Expression Extractor (for segment 1 only): 

Reference Name: s1time  
Regular Expression: "segment_1_time": (\d+)  
Template: $1$  
Match No: 1  
Default Value: 0

I wrote this script in Bean Shell Post Processor to get value of segment_1_time in order to use it for further processing: 

String time_s1= vars.get("s1time");
log.info("Segment 1 time= "+time_s1);

For some reason, I always get NULL in time_s1. I also tried using var time_s1 instead of String time_s1 but it gives null value too. Where am I going wrong?

Regexp - not a good way to parce JSON. JSON Path extractor - is a simple way to do it. Read this article (scroll down to 'Parsing JSON' title) to understand how to do it

Please make the following changes in your regular expression to make it work

Regular Expression: .segment_1_time":(.+?),

"Regular expression extractor does not return value if you give a space"

hope this will help
