resteasy @Consume json fails with java.util.Map -

-

i have following json structure:

{     "foo" : {         "foo1" : {             "txt" : "val",             "txt1" : "val1",             "txt2" : "val2",         },         "foo2" : {             "txt" : "val",             "txt1" : "val1",             "txt2" : "val2",         }     },     "bar" : {         "bar1": {             "txt" : "val",             "txt1" : "val1",             "txt2" : "val2",         },         "bar2": {             "txt" : "val",             "txt1" : "val1",             "txt2" : "val2",         }     } }

while have following pojo:

class pojo {   string txt;   string txt1;   string txt2; }

and resteasy method looks like:

@post @produces({ mediatype.application_json }) @consumes({ mediatype.application_json }) @path("/foo") public void bar(@queryparam("jsonobj") map<string,map<string,pojo>> jsonobj);

however while starting server following error:

i went through documentation , complex objects says use stringconvertor, shouldn't supported simple types list, map etc...

instead of taking json in map> jsonobj format , can use inputstream , can process input stream objects out of it.
