I have a JSON object, generated from a REST service, that looks like this:

```
  {
    "name": "mark",
    "other_details": "{age:34, gender:male}"
  }

```

In the "other\_details" param, the value has to be converted to a JSON object, which ultimately should look like:

```
{
    "name": "mark",
    "other_details": "{
                          "age":"34", 
                          "gender":"male"
                      }"
}

```

My POJO looks like:

```
class Profile{
          String name;
          String other_details;
         //getters and setters
}

```

I need some help regarding converting the value of the "other\_details" param(which is a string) into a JSON.
I did try to use Jackson, but it was of no use.

any ideas, how should I proceed !!
