    <p>I am working on this project where the user enters some data which is written to an XML file.This part is working fine. Now when the user runs the program he should be able to append to that file. Instead it creates a new file with just one entry! A fileoutput stream is also not the solution.</p> <p>Here is the code for serializing to XML</p> <pre><code>String medicine=medicfield.getText(); String doctor=dnamefield.getText(); int duration=Integer.parseInt(dodfield.getText()); int amount=Integer.parseInt(cyclefield.getText()); int inter=Integer.parseInt(intval.getText()); PrescripManager pm=new PrescripManager(); pm.setDcycle(amount); pm.setDosage(duration); pm.setInterval(inter); pm.setmedName(medicine); pm.setdocName(doctor); try{ FileOutputStream file = new FileOutputStream("file.xml"); JAXBContext jaxbContext = JAXBContext.newInstance(PrescripManager.class); Marshaller jaxbMarshaller = jaxbContext.createMarshaller(); // output pretty printed jaxbMarshaller.marshal(pm, file); } catch(Exception ex) { erlbl.setText(ex.getMessage()); } </code></pre> <p>And the Class::</p> <pre><code>@XmlRootElement public class PrescripManager { private String medname,docname; private int interval,dcycle,dosage; private Date dt; public String getmedName() { return medname; } public void setmedName(String medname) { this.medname = medname; } public String getdocName() { return docname; } public void setdocName(String docname) { this.docname = docname; } public int getInterval() { return interval; } public void setInterval(int interval) { this.interval = interval; } public int getDcycle() { return dcycle; } public void setDcycle(int dcycle) { this.dcycle = dcycle; } public int getDosage() { return dosage; } public void setDosage(int dosage) { this.dosage = dosage; } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
