Serialization of Vector Graphics object

Question

I'm writing a Vector base Graphics Software, all objects are stored into a Vector....
Originally, i wanna using XML for saving , but one kind of my objects contains BufferedImage which could not represented by XML , so i decide to save by "ObjectOutputStream".
i know that Vector implements Serializable, plus, i have implements Serializable in my custom objects too....
Unfortunely, it got error as follow:
java.io.WriteAbortedException: Writing aborted by exception; java.io.NotSerializ
ableException: java.awt.BasicStroke
i guess it is because my objects contain some attributes that do not support Serializable , such as BasicStroke, Paint, and some other alse....
Do anyone know how to solve it ??
Thanks very much ~~~

Answer 1

Here is the well functionning code I implemented to save a BasicStroke, where style is the attribut name for my BasicStroke instance.
Declare your BasicStroke attribut as transiant to avoid exception with defaultWrite() operation as explained in previous messages
private void writeObject(ObjectOutputStream s) throws IOException {
s.defaultWriteObject();
float width = this.style.getLineWidth();
int cap = this.style.getEndCap();
int join = this.style.getLineJoin();
float miterlimit = this.style.getMiterLimit();
float[] dash = this.style.getDashArray();
float dash_phase = this.style.getDashPhase();
s.writeFloat(width);
s.writeInt(cap);
s.writeInt(join);
s.writeFloat(miterlimit);
s.writeObject(dash);
s.writeFloat(dash_phase);
private void readObject(ObjectInputStream s) throws IOException {
try{
s.defaultReadObject();
float width = s.readFloat();
int cap = s.readInt();
int join = s.readInt();
float miterlimit = s.readFloat();
float[] dash = (float[])s.readObject();
float dash_phase = s.readFloat();
this.style = new BasicStroke(width,cap,join,miterlimit,dash,dash_phase);
}catch(ClassNotFoundException ioe){System.err.println(ioe.getMessage());}
