This is an XML and its root is DistinctParty, now I need to extract two tags from it via JAVA.
NamePartyValue
VersionDetail
Now I get the root element and can extract NamePartyValue with these methods, but I also need to extract VersionDetail element which I can't even find in the result, could you please direct me in an accurate direction.
public NodeList readXMLFileUpdated(String path) {
File fXmlFile = new File(path);
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = null;
Document doc = null;
NodeList nList = null;
try {
dBuilder = dbFactory.newDocumentBuilder();
doc = dBuilder.parse(fXmlFile);
doc.getDocumentElement().normalize();
nList = doc.getElementsByTagName("DistinctParty");
} catch (Exception e) {
e.printStackTrace();
}
return nList;
}
public List<Company> getCompanyNamesXML(NodeList nodes){
List<Company> listOfCompanies = new ArrayList<>();
for(int i = 0; i<nodes.getLength(); i++)
listOfCompanies.add(new Company(nodes.item(i).getTextContent()));
return listOfCompanies;
}
This statement nodes.item(i).getTextContent() in upper method returns me the value of NamePartyValue field and when trying to get children of this node with this nodes.item(i).getChildNodes() I can't see VersionDetail in the result, any idea what I might be missing?

Just like you found the NodeList of "DistincyParty" by calling doc.getElementsByTagName(), you can find VersionDetail or NamePartValue elements by doing the same thing.

Trying to unmarshal the above xml file to java objects.
Generated Settings.java and ObjectFactory.java file using xjc tool.These files are deployed in the src folder(along with other java files.)
WHen i unmarshal i get null valuues for Connections,Mappings and TypeMappings.
Is there any steps that i am missing?
public class JAXBImpl{

System.out.println(que.getConnections().getConnection());
}

I know the error is occurring because of this line: System.out.println("caffeineIntake");
I want to access this input variable i.e. caffeineIntake to perform some operation on it.

The error is not occurring because of this line: System.out.println("caffeineIntake");
It is occurring because of the Dialect option selection:
Using this option as mvel rather than java resolved the issue.

Well,
from my point of view
String noOfCups = 1;
is the problem.
perhaps change it to
String noOfCups = "1";

How to change output coding of a XML of reading and writing at the same time in with Jdom?

I have this code, I want to read and want to write the "prueba3.xml" at the same time, the file is UTF8 but when I write the file, the encoding changes and displays strange characters, although I have added format.setEncoding("UTF-8"), it is not doing it correctly. Is it possible to change the output encoding to UTF8 with jdom SAXBuilder?
Input XML:
<?xml version="1.0" encoding="UTF-8"?>
<prueba>
<reg id="576340">
<dato cant="856" id="6" val="-1" num="" desc="ñápás" />
<dato cant="680" id="1" val="-1" num="" desc="résd" />
<dato cant="684" id="5" val="-1" num="" desc="..да и вообем" />
<dato cant="1621" id="1" val="-1" num="" desc="hi" />
<dato cant="1625" id="5" val="-1" num="" desc="Hola" />
</reg>
</prueba>
This is the code:
public static void main(String[] args) throws FileNotFoundException, JDOMException, IOException
{
//Se crea un SAXBuilder para poder parsear el archivo
File xml = new File("c:\\prueba3.xml");
Document doc = (Document) new SAXBuilder().build(xml);
Element raiz = doc.getRootElement();
//Recorremos los hijos de la etiqueta raíz
List articleRow = raiz.getChildren("reg");
for (int i = 0; i < articleRow.size(); i++) {
Element row = (Element) articleRow.get(i);
List images = row.getChildren("dato");
for (int j = 0; j < images.size(); j++) {
Element row2 = (Element) images.get(j);
String texto = row2.getAttributeValue("desc") ;
String id = row2.getAttributeValue("id");
if ((texto != null) && (texto !="") && (id.equals("1"))){
row2.getAttribute("desc").setValue("Raúl").toString();
}
}
Format format = Format.getRawFormat();
format.setEncoding("UTF-8");
XMLOutputter xmlOutput = new XMLOutputter(format);
xmlOutput = new XMLOutputter(format);
xmlOutput.output(doc, new FileWriter("c:\\prueba3.xml"));
}
System.out.println("fin");
}
Output XML:
<?xml version="1.0" encoding="UTF-8"?>
<prueba>
<reg id="576340">
<dato cant="856" id="6" val="-1" num="" desc="񡰡s" />
<dato cant="680" id="1" val="-1" num="" desc="Ra򬢠/>
<dato cant="684" id="5" val="-1" num="" desc="..?? ? ??????" />
<dato cant="1621" id="1" val="-1" num="" desc="Ra򬢠/>
<dato cant="1625" id="5" val="-1" num="" desc="Hola" />
</reg>
</prueba>
Greetings and thanks for your time.

This is a relatively common problem to encounter when using JDOM - especially in countries/regions with non-latin alphabets. In some senses I regret maintaining the use of Writer outputs at all in JDOM.
See the JavaDoc on XMLOutputter too: http://www.jdom.org/docs/apidocs/org/jdom2/output/XMLOutputter.html
The issue is that FileWriter uses the default encoding of the system to convert from the Writer to the underlying byte data. JDOM cannot control that conversion.
If you change the line of code:
xmlOutput.output(doc, new FileWriter("c:\\prueba3.xml"));
to use an OutputStream instead of a Writer:
try (OutputStream fos = new FileOutputStream("c:\\prueba3.xml")) {
xmlOutput.output(doc, fos);
}
... it will use the output as a byte-stream, and the systems' default encoding won't interfere with the output.
(P.S. There's no reason to assign the xmlOutput instance twice.)

DBUnit - integrity constraint violation: foreign key no action; SYS_FK_10556

I am currently coding test with dbunit(using hsqldb). However, I have a huge Problem at initializing the db:
here`s the code:
/**
* Init before a test starts
*/
#Before
public void initialise() {
IDataSet dataSetRating = null;
IDataSet dataSetMovie = null;
log.info("enter init test");
try {
con = datasource.getConnection();
icon = new DatabaseConnection(con);
File rating = new File("./src/test/resources/startDatabaseRating.xml");
dataSetRating = new FlatXmlDataSetBuilder().build(rating);
DatabaseOperation.CLEAN_INSERT.execute(icon, dataSetRating);
} catch (Exception e) {
e.printStackTrace();
log.error(e);
System.exit(-1);
}
}
my create statement looks like that:
CREATE TABLE Rating
(
rid INTEGER GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
mid INTEGER FOREIGN KEY REFERENCES Movie(movieId),
rating INTEGER NOT NULL,
);
and my startDatabaseRating.xml looks like that:
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<Rating rid="0" mid="0" rating="1" />
<Rating rid="1" mid="0" rating="2" />
<Rating rid="2" mid="0" rating="3" />
<Rating rid="3" mid="0" rating="4" />
<Movie movieid="0" title="Movie1" moviePath="C" />
<Movie movieid="1" title="Movie2" moviePath="D" />
</dataset>
When I run the tests I get:
java.sql.SQLIntegrityConstraintViolationException: integrity
constraint violation: foreign key no action; SYS_FK_10556 table:
RATING
Why do I get this exception, cause there is still a dataset in the *.xml file. How to fix this problem?
UPDATE:
CREATE TABLE Movie
(
movieId INTEGER GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
title VARCHAR(255) NOT NULL,
moviePath VARCHAR(500) NOT NULL
);

When inserting a rating, the movie that is referenced must already exist in the movie table. So you are inserting the rows in the wrong order.
You need to first insert the movies, then the ratings.
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<Movie movieid="0" title="Movie1" moviePath="C" />
<Movie movieid="1" title="Movie2" moviePath="D" />
<Rating rid="0" mid="0" rating="1" />
<Rating rid="1" mid="0" rating="2" />
<Rating rid="2" mid="0" rating="3" />
<Rating rid="3" mid="0" rating="4" />
</dataset>

Also I would recommand you to use regular labels for your columns, especially for the id and the foreign key, because it is much more easier to understand and to maintain, if another person is in charge of your code some day !
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<Movie id="0" title="Movie1" moviePath="C" />
<Movie id="1" title="Movie2" moviePath="D" />
<Rating id="0" movie_id="0" rating="1" />
<Rating id="1" movie_id="0" rating="2" />
<Rating id="2" movie_id="0" rating="3" />
<Rating id="3" movie_id="0" rating="4" />
</dataset>
