Updating a Record in OFBiz using Java

This is an example on how to update a record in OFBiz using Java as engine. I am assuming that the you have created the service of this method in you service.xml.

public static Map updatePerson(DispatchContext dctx, Map context) {
       Map resultMap = ServiceUtil.returnSuccess();

       //this is how you fetch the values from the request
       String id = (String) context.get("id");
       String firstName = (String) context.get("firstName");
       String lastName = (String) context.get("lastName");
       String gender = (String) context.get("gender");
       String email = (String) context.get("email");

       try {
             GenericValue personGV = delegator.findOne("Person", UtilMisc.toMap("id", id), false);
             if (personGV != null && !personGV.isEmpty()) {
                    personGV.put("firstName", firstName);
                    personGV.put("lastName", lastName);
                    personGV.put("gender", gender);
                    personGV.put("email", email);
                    personGV.store();
             }
       } catch (GenericEntityException e) {
            return ServiceUtil.returnError("Failed. " +e.getMessage());
       }  
       return resultMap;
}
