Thanks Andres, your reply was very useful. I also found http://www.json.org/javadoc/org/json/JSONObject.html#JSONObject(java.lang.Object,%20java.lang.String[]) but then I have to pass the attributes name of POJO object. I will try the toJSON( ) method of JSONSerializer, would it be able to convert the collections in POJO like arrays , maps, lists etc?? Thanks a lot once again, Petr Andres Almiray <aal...@ya...> wrote: Hi Petr, I think you can find what you're looking for in net.sf.json.JSONSerializer It will let you serialize a Java bean, map, array, collection into JSON and back, you may specify a target class when converting back to Java or leave it blank, the result will be a DynaBean compatible with jakarta's bean-utils.
