byte [] x = str.getBytes ();
System.out.println ( new String (x) );
String byStr = "104, 101, 108, 108, 111";
String a [] = byStr.split ( "," );
byte xx [] = new byte[a.length];
int count = 0;
for ( String s :  a)
{
xx[count++] = Byte.parseByte ( s.trim () );
}
System.out.println ( new String (xx) );

Output

fasterxml jackson ObjectMapper produces JSON string with '=' and not ':'

Produces [key=value]
new ObjectMapper ().writerWithDefaultPrettyPrinter ().writeValueAsString ( responseVO.toString() )


Produces {"key":"value"}
new ObjectMapper ().writerWithDefaultPrettyPrinter ().writeValueAsString ( responseVO )


Note : Dont convert toString and pass taht to writeValueAsString ()

Python - Expecting property key name enclosed in double quotes - String to JSON

import demjson 
result = demjson.decode(' { key: "value" }' )


demjson plugin is very good on this
