Deserialize XML and get value using Java

When I use a distance API I get this response:

You can use XmlMapper of jackson to de/serialize your XML.
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.9.8</version>
</dependency>
so you shall need to create an instance of it and deserialize as follows :
XmlMapper mapper = new XmlMapper();
Response value = xmlMapper.readValue("<Response>..</Response>", Response.class);
So you will need to create your object model that reflects your XML.

MongoDB Morphia only saving 1 user

You can't insert more than one because you have duplicateKey: you can't use an #id with primitive type without setting a unique value yourself.
You defined your id like this:
#Id
public int id;
Even though you never set any value for id, primitive types are initialized to 0, so you end up trying to insert multiple documents with the same key.
Solution:
You can either :
change your id to String: #Id String id;
change your id to ObjectId: #Id ObjectId id;
keep #Id int id and manually set a unique value to it (player.getUniqueId() for instance).
The first 2 options will work because they won't be initialized and will be null. Mongo will then generate a unique id for you.

how to write junit test cases for Row Mapper class in spring

The above classes are my Row Mapper and Model class.i do not know how to write junit test class for Row Mapper class .please any one guide me how to write junit test for these classes.
Hi here is my Junit test code for above classes.
public class UserRowMapperTest {
UserRowMapper userRowMapper=null;
#Before
public void runBeforeEachTest(){
userRowMapper= new UserRowMapper();
}
#After
public void runAfterEachTest(){
userRowMapper=null;
}
#Test
public void testMapRow(){
userRowMapper.mapRow(resultSet, line);
}
}

From my point of view there is nothing to test here.
You should create unit tests only for the methods which have some business logic. I don't see the reason to test the methods which are using just getters and setters because in general they don't do anything.
However, if you want just to practice this is the advice what you could do for the unit test. First of all check some questions on how to write the unit tests because it feels like you don't understand what you need/want to achieve.
In general this is the sketch of what you want:
#Test
public void testMapRow(){
// SETUP SUT
UserRowMapper userRowMapper = new UserRowMapper()
// fill (prepare) in the Object that you want to pass to a method.
ResultSet resultSet = createResultSet();
// EXERCISE
UserData resultData = userRowMapper.mapRow(resultSet, line);
// VERIFY
Assert.assertEquals(expectedValue, resultData.getSomeValue())
}
p.s. By the way, there is no point in line parameter in this method because you don't use it.
And about the NullPointerException, please, have a look to quite popular question about it.

How to pass array of string in insert query in ibatis?

How to pass array of string in insert query statement in ibatis. On passing string array as parameter it is giving me this exception of ibatis -

How to normalize your database in hibernate? (Repeating values don't get saved again and again)

imagine I have a table called Photo and a table called Tag.
A Photo can have any amount of tags. Like a picture of the Brandenburg Gate in Berlin has as tags "Berlin", "Gate", ...
Now there is a second photo with the Berlin Reichstag and has also "Berlin" as one of its tags.
At the moment this would now get saved redundantly in my database, this means in my Tag table "Berlin" appears twice and in my join table that has been created by hibernate each tupel directs to its own "Berlin"-Tag.
I don't like this situation, because this means I'm saving redundant data in my database. I would much more like the case that the tag "Berlin" gets only saved once in my Tag-table and each Photo that has this tag gets the reference on this one tag object.
So summarized:
Before (I hope this now gets displayed correctly, when I send this question)
PHOTO
ID | PhotoName
1 | Brandenburg Gate
2 | Reichstag Germany
...| ...
TAG
ID | Tagname
1 | Berlin
2 | Hamster
3 | Berlin
4 | Berlin
5 | Bird
...| ...
PHOTO_TAG (join table)
photoID | tagID
1 | 1
2 | 3
3 | 4
... | ...
Hopefully afterwards:
PHOTO
ID | PhotoName
1 | Brandenburg Gate
2 | Reichstag Germany
...| ...
TAG
ID | Tagname
1 | Berlin
2 | Hamster
3 | Bird
...| ...
PHOTO_TAG (join table)
photoID | tagID
1 | 1
2 | 1
3 | 1
... | ...
As you can see Berlin only needs to get saved once in the Tag table, while there is still no information loss, since the join table references correct on the tupel.
I tried to achieve this with hibernate (I'm not a pro) on a postgresql database. My Photo-Class has an attribute photoTags, which I gave a ManyToMany relationship (I thought that this could mean that every photo can have any amount of tags while every tag can have any amount of photos they're referenced to)
#ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
private Set<Tag> photoTags;
But simply, this didn't work. There is a lot of redundant data in my tag table.
a
Now my question: Do you know any sufficient way for me to realize this? Thank for you for every answer and comment (If you need any further information, like my hibernate.cfg.xml, just tell me).
(This Question here is dealing with a similar problem, but the answer is not satisfying for me:

The way you are expecting it to work is how it's supposed to work.
I don't see anything wrong in the Hibernate model classes you have posted, so I can only assume that you are setting new Tag instances to the photo instead of loading them and setting them.
When you do that hibernate doesn't know if these objects are equal or not because they don't have an ID set (you just create them remember?).
Load the Tag objects and assign them to photos or if you are hell bent on adding new instances remove cascade all option and override the equals method to consider other details than the ID if the id is not set (null).
