I am attempting to save a JList using JAXB marshaling.
This is my marshaling method:
public void save() {
try {
File save = new File("save.xml");
JAXBContext jaxbContext = JAXBContext.newInstance(Window.class);
Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
// output pretty printed
jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
jaxbMarshaller.marshal(listB, save);
jaxbMarshaller.marshal(listB, System.out);
} catch (JAXBException e) {
e.printStackTrace();
}
System.out.println(listB);
}
I print out listB to ensure it works.
I still get the following error message:
javax.xml.bind.JAXBException: class javax.swing.DefaultListModel nor any of its super class is known to this context.

You can only marshal or unmarshal instrumented/annotated classes. I didn't check JList but i don't belive it comes out of the sdk annotated for JAXB. Check the projects official site for more info on how to use JAXB https://jaxb.java.net/

This question already has answers here:
Edit the .properties file inside a jar without extracting it or changed to .zip format
(4 answers)
Closed 3 years ago.
Good morning, this is my method.
public void updatePropertiyByValue(String key, String value, String propFile) throws IOException {
Properties prop = new Properties();
objClassLoader = getClass().getClassLoader();
InputStream objFileInputStream = null;
objFileInputStream = getClass().getClassLoader().getResourceAsStream(propFile);
prop.load(objFileInputStream);
objFileInputStream.close();
OutputStream output = null;
try {
output = new FileOutputStream(objClassLoader.getResource(propFile).getFile());
prop.setProperty(key, value);
prop.store(output, null);
}catch (Exception e) {
e.printStackTrace();
}finally {
output.close();
}
}
It's work is to update properties file. My problem is that the inputStream works good with the getResourceAsStream(propFile) instead the ouput part give me an error:
java.io.FileNotFoundException: file:*********************************\easyDeployment\EasyDeployment\target\EasyDeployment-0.0.1-SNAPSHOT.jar!\configuration.properties (The syntax of the file name, the directory name or the value label is not correct) // translated from my native language

I had this kind of error also when i used the getResource() method for the inputStream (in that case was precisely a fileInputStream).
Is there a way to call the output in a different way?
getResource() provides a URL to the file within the jar (zip file). Java can't open this directly.
You either need to expand the zip file to directory and update in the directory.
Or read in and change the zip file. I, however, must ask why you might do this? Class path resources are typically supposed to be read-only
I've got an debugging problem!
I have written a method that should save an object called "Player" to an .bin file.
Here is the shortest version of my saving method, which includes only the "saving process".
public void saveButton_ActionPerformed(ActionEvent e) {
ObjectOutputStream playerSave;
try {
playerSave = new ObjectOutputStream(new FileOutputStream("save/player_data.bin"));
playerSave.writeObject(Main.player);
playerSave.close();
} catch (FileNotFoundException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
}
Directly after starting this method, i'm getting following errors from the console.

The exception you are getting is occurring when you try to Serialize (ObjectOutputStream.writeObject) your Main.player.
Main.player has an ImageIcon field, that does not have an image, so it cannot be serialized.
This is my code:
public void makeReportAddToPanel()
{
JasperReportBuilder report = DynamicReports.report();//a new report
report
.columns(
Columns.column("Applicant", "ApplicantName", DataTypes.stringType()),
Columns.column("Quiz", "Quiz", DataTypes.integerType()),
Columns.column("Score", "Score", DataTypes.integerType()))
.title(//title of the report
Components.text("Score Per Quiz")
.setHorizontalAlignment(HorizontalAlignment.CENTER))
.pageFooter(Components.pageXofY())//show page number on the page footer
.setDataSource("Select answer,userId,questionId from quizTaken",dao.Connection.getDBConnection());
try {
//show the report
JRViewer view = new JRViewer(report.toJasperPrint());
report.show();
this.add(view);
//export the report to a pdf file
report.toPdf(new FileOutputStream("/report.pdf"));
} catch (DRException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
This is the stacktrace

So I am trying to build a report and putting it into a panel but when I run the code I get this error ... When I look into the jasperreport jar the package JRScriptlet is not included
Your project is missing a dependency.
So, you must add the jasperreport-xxx.jar (with xxx corresponding to your targeted version) to your classpath.
If you're using maven add the GAV parameters to your pom.xml file with the adequate scope (compile by default).
I am using hsqldb and would like to delete all records from a table.
Right now I am trying to do that with:
em.createQuery("DELETE FROM Datatable").executeUpdate();

Any recommendations about this case?
You need to control commit/rollback when finalising the changes made on database.
try {
em.getTransaction().begin();
..do what you need to do..
em.getTransaction().commit();
} catch(Exception ex) {
em.getTransaction().rollback();
throw ex; // let upper methods know this did not go well
}
you should try it this way:
#Resource
UserTransaction mUserTransaction;
public void delete()
{
mUserTransaction.begin();
em.createQuery("DELETE FROM Datatable").executeUpdate();
mUserTransaction.commit();
}
I have made a program and I want to release it but I have 5-6 HTTP librarys(.jar) for update checks how can I get them together to a single file?
Ive tried eclipse fat jar maker but it doesnt work that good it throws me an eception when the proram is trying to check if a file exists and it doesnt find it.
File getting code:
public class NotesFile {
private File notesFile = new File("notes").getAbsoluteFile();;
public void saveNotes(String notes) {
try {
PrintWriter writer = new PrintWriter(new FileWriter(this.notesFile));
writer.print(notes);
writer.close();
} catch (Exception ex) {
ex.printStackTrace();
}
}
public String getNotes() {
String notes = "";
try {
if (!notesFile.exists()) {
System.out.println("File loading failed ignoring load method.");
return "";
}
BufferedReader reader = new BufferedReader(new FileReader(this.notesFile));
String var1 = "";
while ((var1 = reader.readLine()) != null) {
notes = notes + var1 + "\n";
}
reader.close();
} catch (Exception ex) {
ex.printStackTrace();
}
return notes;
