i working on api portal, provide users ability update there data via api directly there internal systems. liferay 6.2 bundle tomcat. (for api call testing use soapui)

the methods work fine, (i have getall, , getbyid). getbyid returns json object this:

{      "id": "organizationid",      "type": "organizationtype",       "name": "organizationname",      "uri": "organizationnameuri"      "date of inclusion": "inclutiondate",       "last activities": "lastmodifieddate",      "address": {          "name of host institution": "nameofhostinstitute",          "street1": "street1",          "street2" : "street2",          "zip": "zip",          "city": "city",          "country": "country",      },      "url": [{"organizationurl"}],      "main contact": {          "first name": "firstname",          "last name" : "lastname",          "phone": "phone",          "email": "maincontactemail"      },      "type of host institution" : "typeofhostinstitute",       "diseases":  [         {          "name": "diseasename1",          "number": "samplecount",          "gene": "gene",           "orphacode": "orpha"          "icd10": "icd",          "omim": "omim";          "synonym": "synonym"          },         {          "name": "diseasename2",          "number": "samplecount",          "gene": "gene",           "orphacode": "orpha"          "icd10": "icd",          "omim": "omim";          "synonym": "synonym"          }      ] } 

i have api updating diseases information organization. have created url service in url parameters, have in url id parameter send , rest of information in json object. like: /api/jsonws/....-portlet...../updateregbb/organization-id/16016/ , data:

{      "id": "organizationid",      "diseases":  [         {          "name": "diseasename1",          "number": "samplecount",          "gene": "gene",           "orphacode": "orpha"          "icd10": "icd",          "omim": "omim";          "synonym": "synonym"          },         {          "name": "diseasename2",          "number": "samplecount",          "gene": "gene",           "orphacode": "orpha"          "icd10": "icd",          "omim": "omim";          "synonym": "synonym"          }      ] }
