Problem in JFileChooser

Problem in JFileChooser - java

I want to use JfileChooser to choose a file and writeObject to the selected file or readObject from the selected file. I have serialize my class but I don't know how to serialize this MetalFileChooserUI? Or do I need to do it? Thank you very much.
smiliar error message to mine
Can someone help me to find a solution to it? Thank you.

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.

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

Main.player has an ImageIcon field, that does not have an image, so it cannot be serialized.

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.

Stackoverflow error when writing larger size object to a file

When I give a smaller size input file, there is no error. But when giving an input file of a larger size, I am getting an error. I'm creating a tree object for that input file, and I then want to save the object to the file. The file will be created and when it writes later, it's giving an error.
Does anybody know how to write a larger object to a file using
ObjectOutputStream?
try{
JOptionPane.showMessageDialog(null,"in try");
FileOutputStream fout = new FileOutputStream("d://obj.ser");
JOptionPane.showMessageDialog(null,"obj created");
ObjectOutputStream foos = new ObjectOutputStream(fout);
JOptionPane.showMessageDialog(null,"oos created"); //till here i get output
foos.writeObject(tree);
JOptionPane.showMessageDialog(null,"here compltes writeobj");
foos.flush();
JOptionPane.showMessageDialog(null,"after flush");
//foos.close();
fout.close();
JOptionPane.showMessageDialog(null,"alll");
}catch(Exception ex){
JOptionPane.showMessageDialog(null,"error");
}
Tree file is :
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.swing.JTextArea;
/**
* This is an implementation of a MISTree (which is modified from a fptree).
*
*
*/
public class MISTree implements Serializable {
// List of items in the header table
private static final long serialVersionUID = 5950169519310163575L;
List<Integer> headerList = null;
// List of pairs (item, node) of the header table
Map<Integer, MISNode> mapItemNodes = new HashMap<Integer, MISNode>();
// root of the tree
MISNode root = new MISNode(); // null node
/**
* Constructor
*/
MISTree() {
}
/**
* Method for adding a transaction to the fp-tree (for the initial
* construction of the FP-Tree).
*
* #param transaction
*/
public void addTransaction(List<Integer> transaction) {
MISNode currentNode = root;
// For each item in the transaction
for (Integer item : transaction) {
// System.out.println("item in this transaction is "+item);
// look if there is a node already in the FP-Tree
MISNode child = currentNode.getChildWithID(item);
if (child == null) {
// there is no node, we create a new one
MISNode newNode = new MISNode();
newNode.itemID = item;
newNode.parent = currentNode;
// we link the new node to its parrent
currentNode.childs.add(newNode);
// we take this node as the current node for the next for loop
// iteration
currentNode = newNode;
// We update the header table.
// We check if there is already a node with this id in the
// header table
MISNode headernode = mapItemNodes.get(item);
if (headernode == null) { // there is not
mapItemNodes.put(item, newNode);
} else { // there is
// we find the last node with this id.
while (headernode.nodeLink != null) {
headernode = headernode.nodeLink;
}
headernode.nodeLink = newNode;
}
} else {
// there is a node already, we update it
child.counter++;
currentNode = child;
}
}
}
// here some other methods like to print a tree and other are there
}
MIS Node also serialized.
And it works fine for smaller tree. no error but for larger size tree its giving an error
Error is like this:

I get the feeling the issue is your tree structure. ObjectOutputStream works by serializing the objects, and when serializing an object all members of that object will themselves be serialized by default (leaving aside certain edge cases), which means if you have a deeply-nested tree, each level in the tree will mean more calls to the serialization functions. (I don't think cyclic references would be part of the problem, as Java's serializer keeps track of backreferences, but that may only work for already-serialized objects rather than objects in the process of being serialized so you may want to check on that too.)
I would suggest flattening out the tree in some fashion and writing the objects individually rather than trying to write the entire tree as one object. Then, when you read the objects in with an ObjectInputStream, rebuild the tree from the flattened objects.

How to save a JLayeredPane?

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:

Problem in JFileChooser - java

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.
