The key values in the objects need to be in quotes.

Your json is not valid.

The paramsArray,paramsObj,one,three and paramsStr should be wrapped beetween double quotes (a valid JSON has keys and values both wrapped).

String s = "{\"paramsArray\": [\"first\", 100],"
            + "\"paramsObj\": {\"one\": \"two\", \"three\": \"four\"},"
            + "\"paramsStr\": \"some string\"}";

Try a JSON validator like JSONLint.

"{ 'paramsArray': ['first', '100']," + 
  "'paramsObj': { 'one':   'two'," +
                   "'three': 'four'}," +
  "'paramsStr': 'some string'}"

Use single quotes inside double ones to increase readability like so...

Although some parsers may accept single quotes, the JSON specification specifically says that names, which are string values, need to be enclosed in double quotes ".
