Good point. Just wanted to see if anybody recognises the flaw This probably would help:
label.setText("");

You could use a JList as suggest before and use your own list cell renderer for your images. Your renderer could look like this, assuming that your values are ImageIcons.
public class YourRenderer extends DefaultListCellRenderer { @Override public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { Component c = super.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus); JLabel label = (JLabel)c; ImageIcon icon = (ImageIcon)value; label.setIcon(icon); return c; } }

Happy I could help

A bound property fires a PropertyChangeEvent when the property's value changes and hence informs listeners about changes. A constraint property fires a VetoableChangeEvent and next to informing also allows the listener to veto the change.

There is a good source for some special Swing functions at http://www.javarichclient.com Background image for JList can be found here http://www.javarichclient.com/display-a-jlist-with-a-background-image/

There is a quite good video tutorial http://vimeo.com/27961743 about installing Android plug-ins to Eclipse from Scott Stanchfield, but you can retrieve general information about plug-in installation.

TableModelListener is definitely the better solution.

Implement the setValueAt() method in your table model. In setValueAt() fire a property change to inform listeners on changes. In the listener class update your database with new values.

setValueAt() in your table model

@Override public void setValueAt(Object object, int rowIndex, int columnIndex) { Item item = items.get(rowIndex);//items is holding the data, e.g. in an ArrayList switch (columnIndex) { case 0 : return; case 1 : String description = (String)object; item.setDescription(description); break; case 2 : String size = (String)object; item.setSize(size); break; default: assert(false); } super.fireTableRowsUpdated(rowIndex, rowIndex); //update your JTable boolean changed = !this.cellChanged; this.changeSupport.firePropertyChange("cellChanged", this.cellChanged, changed); //inform listeners about changes this.cellChanged = changed; }

Listen on changes in your listener class and update the database

public void propertyChange(PropertyChangeEvent evt) { String propertyName = evt.getPropertyName(); if (propertyName.equals("cellChanged")) { //retrieve the currently selected object in your JTable //update your database with the changed object } }

I assume you retrieve data from a database and want to display the data in a JTable. If so forward the data to your table model and invoke fireTableDataChanged(). The old data will be cleared and replaced by the new data.

Use Java2D to do graphics. You have to create your chart model and than draw the bars in a panel with Graphics2D. There is quite good tutorial at the Java Tutorial site. You could also look at SwingX, they have extensions for Swing also charts.

Jaikiran,
thanks a lot!

Here is my persistence.xml
<?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <!--<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">--> <persistence-unit name="peoplePU" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <class>people.person.Person</class> <class>people.communication.Address</class> <class>people.company.Company</class> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/> <property name="hibernate.connection.username" value="user"/> <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/> <property name="hibernate.connection.password" value="user"/> <property name="hibernate.connection.url" value="jdbc:hsqldb:hsql://databaseserver:9002/people"/> </properties> </persistence-unit> </persistence>

So in the above persistence.xml version databaseserver:9002 is the database server accessible within the LAN. If I am traveling (with my notebook PC) and I want to access the database I have to change databaseserver:9002 to something like www.mydomain.com:9002. This I would like to do with starting up a preferences dialog where I can change the database server address without re-compiling and re-JARing.

Any idea?
