How to save a JLayeredPane? - java

Hi I am using a JLayeredPane which has many JTextPanes, buttons, labels etc.
I am using Serialization to save it but gives non-serializable exception.
How do I actually save it?
This is the code where I am trying to serialize JLayeredPane
FileOutputStream fos = null;
ObjectOutputStream os = null;
try
{
fos = new FileOutputStream(file+".pd");
os = new ObjectOutputStream(fos);
os.writeObject(tempPane);
System.out.println("Saved Successfully");
}
catch (Exception ex)
{
ex.printStackTrace();
}
where tempPane is the JLayeredPane.
However, I am getting a java.io.NotSerializableException:

Java Application Hangs SomeTimes

We are trying to automate the Java Browser based application using BluePrism. I am using Internet explorer as application and enabled Java techniques in application moduler. I am able to spy the elements and able to perform operations like focus, write, read, select tree views etc. But some times Java application will hang and blue prism will not respond. So some of the operation will fail because of this i.e., Blueprism unable to select the country or state from the drop down. We are following all the best practices provided by blue prism but still we are facing this issues some times. Please let me know for any solution.
Even manually if we open the application we are getting the below error sometimes.
Note: Java application and BluePrism are hosted inside Azure VM

IOException / Java Security Access Error when saving a file

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.
java.io.IOException: failed to load image contents

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.

Right now I am trying to do that with:

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();
}

Thanks

Did you configure your JNDI Datasource for the report designer?
From the Pentaho infocenter:
Edit the .pentaho/simple-jndi/default.properties file. The .pentaho
directory is in the home or user directory of the user account that
runs Report Designer. If you have multiple copies of Report Designer
installed to multiple user accounts, each default.properties file will
have to be edited.

If you do not actually want to serialize the JFileChooser but you simply have a reference to it in some class of yours (that you need to serialize) make that reference transient so the serialisation process will simply ignore it.

I'm not sure why you would want to serialize a file chooser as what would be the sense in this? I think that your best bet is to not serialize the gui portion of a program but rather the data held in the model (assuming an MVC structure) -- unless you have requirements that we need to know about.
