How to merge 2 JSON objects from 2 files using jq?

I'm using the jq tools (jq-json-processor) in shell script to parse json.

I've got 2 json files and want to merge them into one unique file

Here the content of files:

file1

{"value1": 200,"timestamp": 1382461861,"value": {"aaa": {"value1": "v1","value2": "v2"        },"bbb": {"value1": "v1","value2": "v2"        },"ccc": {"value1": "v1","value2": "v2"        }    }}

file2

{"status": 200,"timestamp": 1382461861,"value": {"aaa": {"value3": "v3","value4": 4        },"bbb": {"value3": "v3"        },      "ddd": {"value3": "v3","value4": 4        }    }}

expected result

{"value": {"aaa": {"value1": "v1","value2": "v2","value3": "v3","value4": 4        },"bbb": {"value1": "v1","value2": "v2","value3": "v3"        },"ccc": {"value1": "v1","value2": "v2"        },"ddd": {"value3": "v3","value4": 4        }    }}

I try a lot of combinations but the only result i get is the following, which is not the expected result:

{"ccc": {"value2": "v2","value1": "v1"  },"bbb": {"value2": "v2","value1": "v1"  },"aaa": {"value2": "v2","value1": "v1"  }}{"ddd": {"value4": 4,"value3": "v3"  },"bbb": {"value3": "v3"  },"aaa": {"value4": 4,"value3": "v3"  }}

Using this command:

jq -s '.[].value' file1 file2
