Hi friends,
I want to generate Jaxb pojo classes using xjc by java code not by using command prompt how i will use it.
public static void main(String [] args) throws FileNotFoundException
{
try
{
JAXBContext jc = JAXBContext.newInstance(new Class[] {com.bcbsks.testjb.Report.class});
Unmarshaller um = jc.createUnmarshaller();
Report myJAXBObject = (Report)um.unmarshal(new java.io.FileInputStream("report.xsd"));
}
catch( UnmarshalException ue )
{
ue.printStackTrace();
}
catch( JAXBException je )
{
je.printStackTrace();
}
}
I know that given code is wrong but i want to use any other code for generating pojo classes.
Try:
com.sun.tools.xjc.Driver.run(String[], XJCListener)
Where the String[] are the parameters passed to the XJC command the the implementation of XJCListener looks something like the following:
public class Listener extends XJCListener {
private ConsoleErrorReporter cer = new ConsoleErrorReporter(System.err);
private String generatedPackagePath = null;
public void generatedFile(String fileName, int count, int total) {
message(fileName);
if (this.generatedPackagePath == null) {
this.generatedPackagePath = fileName.substring(0, fileName.lastIndexOf(File.separator));
}
}
public String getGeneratedPackagePath() {
return generatedPackagePath;
}
public void message(String msg) {
System.out.println(msg);
}
public void error(SAXParseException exception) {
cer.error(exception);
}
public void fatalError(SAXParseException exception) {
cer.fatalError(exception);
}
public void warning(SAXParseException exception) {
cer.warning(exception);
}
public void info(SAXParseException exception) {
cer.info(exception);
}
}

I am trying to make my class implement VersionedPortable.
It has a field
ArrayList<byte[]> someMessages = new ArrayList<>();
How do I specify this field in my ClassDefiniton?
I assume it would be something like
new ClassDefinitionBuilder(FACTORY_ID, MESSAGE_BUNDLE_CLASS_ID, VERSION_ID)
.addPortableArrayField("someMessages", ?? what goes here ??)
And how would I read and write them?
Arrays of arrays are not supported in the Portable format by default. However, you can use the following trick to wrap the nested array as a separate Portable type and write your field as a Portable array.
class Foo implements Portable {
private ArrayList<byte[]> messages;
#Override
public int getFactoryId() {
return 1;
}
#Override
public int getClassId() {
return 1;
}
#Override
public void writePortable(PortableWriter writer) throws IOException {
Portable[] wrappedMessages = messages.stream()
.map(ByteArrayWrapper::new)
.toArray(Portable[]::new);
writer.writePortableArray("messages", wrappedMessages);
}
#Override
public void readPortable(PortableReader reader) throws IOException {
messages = Arrays.stream(reader.readPortableArray("messages"))
.map(item -> ((ByteArrayWrapper) item).getArray())
.collect(Collectors.toCollection(ArrayList::new));
}
}
class ByteArrayWrapper implements Portable {
private byte[] array;
public ByteArrayWrapper() {
}
public ByteArrayWrapper(byte[] array) {
this.array = array;
}
#Override
public int getFactoryId() {
return 1;
}
#Override
public int getClassId() {
return 2;
}
#Override
public void writePortable(PortableWriter writer) throws IOException {
writer.writeByteArray("array", array);
}
#Override
public void readPortable(PortableReader reader) throws IOException {
array = reader.readByteArray("array");
}
public byte[] getArray() {
return array;
}
}
I am working on a JavaFX application which facilitates all kind of sport related training sessions. Each session consists of multiple exercises, whereas each exercise is repeated multiple times in a few sets. I created some test data and marshalled it. As it turned out, some fields of the Exercise class objects were written but not all of them. By adding the #XmlElement(name="someTagName") tag to each getter of each field I managed that all fields are marshalled and the xml file looks like expected. However, when I unmarshall the xml file, only those fields, which were written without the #XmlElement tag are read and most of the fields only have the default value from the constructor. What am I missing in order to unmarshall all fields?
Here is the class that I want to marshall/unmarshall

I used this to marshall
public void save(Session session) {
try {
JAXBContext jc = JAXBContext.newInstance(Session.class);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(session, new File(System.getProperty("user.home"), ".sifuSays/sessions/" + session.getName() + ".xml"));
} catch (JAXBException e) {
System.err.println("Cannot save session " + session.getName());
e.printStackTrace();
}
}
which generates the following xml file
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Session>
<exerciseList>
<exercise>
<selected>true</selected>
<breakBetweenSetsInSec>5</breakBetweenSetsInSec>
<displayTimeInSecs>-1</displayTimeInSecs>
<endSpeed>3.0</endSpeed>
<mediaFilePath>Tan Pak Gan.mp4</mediaFilePath>
<name>Solo Tan Pak Gan Drill</name>
<numOfSets>2</numOfSets>
<repsPerSet>3</repsPerSet>
<showIntro>false</showIntro>

</exercise>
<exercise>

<withMetronom>false</withMetronom>
</exercise>
</exerciseList>
<breakBetweenExercisesInSec>10</breakBetweenExercisesInSec>
<name>MMA - Solo</name>
</Session>
and this is the unmarshaller code
public ObservableList<Session> loadSessions() {
sessions = FXCollections.observableArrayList();
try {
List<File> xmlSessionFiles = Stream.of(
new File(System.getProperty("user.home"), ".sifuSays/sessions/").listFiles())
.filter(file -> !file.isDirectory())
.filter(file -> file.getName().endsWith("xml"))
.collect(Collectors.toList());
for(File xmlSessionFile: xmlSessionFiles) {
JAXBContext jc = JAXBContext.newInstance(Session.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
Session session = (Session) unmarshaller.unmarshal(xmlSessionFile);
sessions.add(session);
}
} catch (JAXBException e) {
System.err.println("Cannot load sessions");
e.printStackTrace();
}
return sessions;
}
While numOfSets is marshalled, repsPerset is not. Neither startSpeed or stopSpeed are unmarshalled and neither withMetronom or showIntro. But name and mediaFilePath are marshalled. What's wrong?
You are mixing up boxed (Double, Integer) and unboxed (double, int) types. I recommend sticking to boxed types for marshalling since otherwise you'll end up with things set to 0 that you weren't expecting.
This Is Main Fragment

here i need onitemclick with blockslug please any one can help, am new to android so i need some example.when on click i want take blockslug and load another method with that blockslug,like will get data from u "http://example.com/block/"+blockslug
i want to get blockslug from selected block
i hope guys i will get help
and sorry for my bad English,
First of all, you need to implement setOnItemSelectedListener. Refer to this https://stackoverflow.com/a/20151596/9346054
Once you selected the item, you can call them by making a new method. Example like below
public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) {
Toast.makeText(parent.getContext(),
"OnItemSelectedListener : " + parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_SHORT).show();
final String itemSelected = parent.getItemAtPosition(pos).toString();
showBlockSlug(itemSelected);
}
And then, at the method showBlockSlug() , you can call Retrofit.
private void showBlockSlug(final String blockslug){
final String url = "http://example.com/block/"+ blockslug;
//Do your stuff...
}
I am converting xml to csv using spring batch and integration. I have a approach that job will start by reading files in from landing dir. while processing it will move files in inprocess dir. on error file will be moved to error dir. on successfully processing/writing file will be moved to output/completed.
After searching a while i got to know that there must be problem with itemreader but it is also returning null. I am not getting where is the problem.
Below is my batch configuration
#Bean

Try to return document itself instead of Object in read method of CommReader.java and then check whether its coming null or not in the writer to stop it.

When don't read the file every thing ok, the Log is populated and every thing runs smooth,
but when i attach the Task.Factory.StartNew(ReadFile); method i have an exception.
Exception:
Cannot access a disposed object.
Object name: 'The ThreadLocal object has been disposed.'.
How do i solve that issue? might i need to change the LocalThread logic, or what - i have been trying to handle that issue, for almost a day.
BTW: It's an MVC4 project, and C# 5.0 and i'm trying to TDD it all.
You shouldn't be calling TasksToExecute.Dispose();
there.
