How do you pass in null values into a HashMap?
The following code snippet works with options filled in:
HashMap<String, String> options = new HashMap<String, String>();
options.put("name", "value");
Person person = sample.searchPerson(options);
System.out.println(Person.getResult().get(o).get(Id));
So the issue is what has to be entered into the options and or method to pass in a null value?
I tried the following code without any success:
options.put(null, null);
Person person = sample.searchPerson(null);
options.put(" ", " ");
Person person = sample.searchPerson(null);
options.put("name", " ");
Person person = sample.searchPerson(null);
options.put();
Person person = sample.searchPerson();
HashMap supports both null
keys and values
http://docs.oracle.com/javase/6/docs/api/java/util/HashMap.html
... and permits null values and the null key
So your problem is probably not the map itself.
