Int 2 Serializable
I have a file with a construction:
Serializable[] serializable = new int[n];
It was generated with jad.exe decompiler from .class file.
When I use javac compiler (java version v1.2.2)
it reports an error that the types java.io.Serializable and int is incompatible
any ideas?
PS
Sorry for my english
I do not know why you change int to Serializable?
The Serializable is a interface that has no methods or fields and serves only to identify the semantics of being serializable. It means Serializable only a signal to tell compiler one class can be serializable. so I think use Serializable array may be a mistake.
The int is a basic type in Java, NOT a class. So it can not change to any class.
By away, one int array can be image to one object, actually the JVM treated the array ( include basic type and object ) as a object.

HELP!
I'm having problems finding a missing or extra bracket within my code? Or at least I thik that is the problem.
The error I get is:
<----
270. try
542. }
--------^
*** Syntax Error: "Finally" inserted to complete TryStatement
I've tried using comparison software but it doesn't help!
I have attached the section of code that is causing the problem, but I think it may be deeped that just the following section.
All the brackes "seem" to match, but 271 goes to 501 in theory, but when I rightclick in my software (JCreator) and choose match bracket, it takes me to 531?
Anyhelp please!! Be most grateful!

The thing is, I have just been looking throughit after what you said and there seems to be only one catch and 3 trys and before I (fooked) around with it, it worked???

Hello all,
When deploying my application to WLS 8.1, I keep getting warnings along the lines of
<Warning> <EJB> <BEA-012034> <The Remote interface method: '//snip// Foo.bar(java.lang.String,int) throws java.rmi.RemoteException //snip// contains a parameter of type: 'int' which is not Serializable. Though the EJB 'Foo' has call-by-reference set to false, this parameter is not Serializable and hence will be passed by reference. A parameter can be passed using call-by-value only if the parameter type is Serializable.>
This message completely confuses me. Since 'int' is a primitive, it cannot implement the Serializable interface. On the other hand this is not necessary since the JVM knows how to serialize primitives anyway. Furthermore, primitives are by Java specification always passed by value.
My assumption is that this message is essentially bogus, a weblogic bug if you want, and the int parameter will indeed be passed by value no matter what the warning says. I just cant se how WLS could pass it by reference given that it is running on a VM that implements the java standard.
Am I missing something here? Please give me your thoughts on this one. We have a customer who is very concerned about these warnings showing up in the log...
Thank you
Message was edited by:
[email protected]Hello, and thanks for taking a stab at this.
While it is great that the fix you ar putting into SP5 allows the administrator to supress BEA-012034 warnings all together, would it not be better to simply correct the code not to issue BEA-012034 warnings for ints, floats and other primitives? Enabeling your fix would indeed make these incorrect messages go away, but it will also supress correct BEA-012034 warnings should our ejb interface [heaven forbid :] contain non-serializable objects.
thanks -

Object Replacement with the existing one int the Serialization Stream..
when u readObject() from serialization its fine,but if u change any of its fields or value of variable and than store it back,it append new object to the Serialization Stream.
I want to store that object back to its original position in the stream.
please help me in this regard..you need to use (override) the readResolve() and writeReplace() methods in the classes that you'll be switching their instances/values/etc. with something else.
Look at the javadocs for the java.io.Serializable interface.
Another option is to subclass the ObjectInputStream and override the resolveObject method. (see java.io.ObjectInputStream). You'll probably also have to subclass ObjectOutputStream and override the writeObjectOverride method.
You really only need to use one of these mechanisms, not both.

Will 2D objects in java.awt.geom.* be Serializable in next version of Java?
I am pretty frustrated about having to write my own Serializable classes. I'm not sure if this is the right place to ask, but will the next version of Java supports Serializable 2D objects?
Further, I was trying to write my own class to extend java.awt.geom.GeneralPath to become Serializable, but it's declared "final". What should I do? (I had no problems with Rectangle2D.Double, Line2D.Double, etc.)
Any help is greatly appreciated.
SelwynYour code for serializing the state of the General path forgets two things:
1. the winding rule
2. the segments types!
You could use a vector, but I just directly wrote to the file:
private void writeObject(ObjectOutputStream oos) throws IOException
{ out.defaultWriteObject();
//write state of transient GeneralPath _gp;
out.writeInt(_gp.getWindingRule());
float[] coord = new float[6];
PathIterator i = _gp.getPathIterator(null);
while(!i.isDone())
{ int seg = i.currentSegment(coords);
writeInt(seg);
//switch on seg, writing correct # of floats from coords
i.next();
out.writeInt(-1); //sentinel for end-of-data: SEG_LINETO etc are [0,4]
private void readObject(ObjectInputStream in)
throws IOException, ClassNotFoundException
{ in.defaultReadObject();
int rule = in.readInt();
_gp = new GeneralPath(rule);
//etc...
}3. I'm just winging this code -- haven't tested it
--Nax -
Problem with writing and reading using serialization
I am having a problem with writing and reading an object that has another object in it. The purpose of the class is to write a order that has multiple items in it. And there will be several orders. This is for an IB project, where one of the requirements is to utilize a hierarchical composite data structure. That is, it is "one that contains more than one element and at least one of the elements is a composite data structure. Examples are, an array or linked list of records, a record that has one field that is another record, or an array". The code is shown below:

Trying to serialize C# object and store as XML Datatype in Sql Server 2005
using
if (Obj != null)
MemoryStream stream = new MemoryStream();
StreamWriter writer = new StreamWriter(stream);
XmlSerializer x = new XmlSerializer(Obj.GetType());
x.Serialize(writer, Obj);
writer.Close();
byte[] arr = stream.GetBuffer();
return Encoding.UTF8.GetString(arr).Trim();
The object looks like

public int couponFreq; // CPN_FREQ
public string floater; // FLOATER
public int resetFreq; //REFIX_FREQ

I have also tried
XmlSerializer x = new XmlSerializer(Obj.GetType());
System.Text.StringBuilder builder = new System.Text.StringBuilder();

Web Service From Java class, serialization problem
Hi,
I want to create Web Service from Java class, I made java project, generated web service from it, create web service archive project and deployed it to WAS 6.40.
My class have 2 methods,
public int add(int a, int b);
public MyResponse doSomthing(MyRequest req);
I can succesfully call add method from Web Service Navigator, it works fine but when I call doSomthing methods I get the following error:
<b>
Deserializing fails. Nested message: XML Deserialization Error. Result class [com.mycomp.sap_tech.ws.MyRequest] does not have property [Amount] of type [java.lang.String]. It is required to load XML..
</b>
Any ideas how to resolve it?
P.S. MyRequest class is exposed throw VI, has default constractor and public getters and setters for all properties. It implements Serializable as well. Any guesses?
Thanks in advance,
Victor.Hi Bhavik, thanks for response.
as I already mentioned it implements Serializable, so it is not the problem.
Thanks Avi but it didn't helps iether

Java.rmi.ServerException: Internal Server Error (serialization error....)
Hi to all.
I have two classes.
The first is:
public class FatherBean implements Serializable {
public String name;
public int id;
/** Creates a new instance of ChildBean */
public FatherBean() {
this.name= null;
this.id = 0;
public String getName() {
return name;
public void setName(String name) {
this.name = name;
public int getId() {
return id;
public void setId(int id) {
this.id = id;
The second is :
public class ChildBean extends FatherBean implements Serializable {
public double number;
/** Creates a new instance of ChildBean */
public ChildBean() {
super();
this.number = 0.0;
public double getNumber() {
return number;
public void setNumber(double number) {
this.number = number;
A test client class implements the following method that is exposed as web service:
public java.util.Collection getBeans() {
java.util.Collection beans = new ArrayList();
ChildBean childBean1 = new ChildBean();
ChildBean childBean2 = new ChildBean();
childBean1.setId(100);
childBean1.setName("pippo");
childBean1.setNumber(3.9);
childBean2.setId(100000);
childBean2.setName("pluto");
childBean2.setNumber(4.7);
beans.add(childBean1);
beans.add(childBean2);
return beans;
When I invoke the web service to url:
http://localhost:8080/Prova
and invoke the correspondent method on jsp client, throws exception:
java.rmi.ServerException: Internal Server Error (serialization error: no serializer is registered for (class test.ChildBean, null))

Where is the problem? Will be ChildBean that extends FatherBean? Wich settings on Sun Java Studio Enterprise 6 2004Q1?

This forum is for Sun Java Studio Creator related questions. Could you pls post your message in the appropriate forum.
Thank you

Hyperterminal has serial comm drivers as well. It just so happens that Hyperterminal is using the serial comm drivers that are built into Windows. That's why you don't notice them.
If you installed LabVIEW, then you should have installed the drivers that come with it. It is on a separate DVD. Obviously you haven't. -

A.show();

}Your originaly source did not include the call to the
close method of ObjectOutputStream which is why your
file was created but empty. I assumed you added it
after the call to writeObject.
Well, that isn't the case. I posted that I added flush().
Read the API docs on the FilterDescriptor class.
This class basically represents an opened file (or
r other open streams) in either an inputstream OR
outputstream. So when you close the outputstream.
The file is not open anymore and thus the
e FileDescriptor object is no longer valid because it
represents and open stream.
I didn't have to read the API docs because to me that seemed like common sense: if I have an object that represents a connection to a file, and I close the connection, it makes sense to me that the object would no longer be valid. Therefore, I didn't use close() in my program.
As far as avoiding lots of try blocks, why not wrap
the whole program in a try block? I assume you're
using all those System.out.println commands to help
debug. It'd be more helpful if you called
printStackTrace on the thrown exception when an error
occurs.
Ok, thanks.
I've done some more tests, and the problem isn't specific to serialization. I'm also unable to use a FileDescriptor when reading a char from a file. I get the same "access denied" error:

System.out.println("io exception createNewFile()");
//Create a FileInputStream:
FileOutputStream out = null;
try
out = new FileOutputStream(myfile);
catch(FileNotFoundException exc)
System.out.println(exc);
System.out.println("error creating FileOutputStream");
//Get the FileDescriptor:
FileDescriptor fd = null;
try
fd = out.getFD(); //a file connection
catch(IOException exc)
System.out.println(exc);

Done.
Done.

Done.I have the following class:
class PrintObject implements Printable
private String propertyFile = "printer.properties";
private HashPrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();
private Properties properties = new Properties();
public int print (Graphics g, PageFormat f, int pageIndex)
private void saveAttributes()
System.out.println("Saving print attributes...");
try
// open property file for writing
ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(propertyFile));
// save printer selection
properties.setProperty("Printer", job.getPrintService().getName());
// write properties object
out.writeObject(properties);
// write attributes object
out.writeObject(attributes);
// close property file
out.close();
System.out.println("Done.");
catch (Exception e)
System.out.print("Could not save print properties: ");
e.printStackTrace();
private void loadAttributes()
System.out.println("Loading print attributes...");
try
// open a property file
ObjectInputStream in = new ObjectInputStream(new FileInputStream(propertyFile));
// read in the properties object
properties = (Properties)in.readObject();
// restore printer selection
PrintService[] services = PrinterJob.lookupPrintServices();
for(int i = 0; i < services.length; i++)
if( services.getName().toString().compareTo(properties.getProperty("Printer", "").toString()) == 0)
try {
job.setPrintService(services[i]);
} catch (PrinterException e)
// Couldn't select a service, sorry
break;
// restore attributes
attributes = (HashPrintRequestAttributeSet)in.readObject();
// close property file
in.close();
System.out.println("Done.");
catch (Exception e)
System.out.print("Could not load print properties: ");
e.printStackTrace();
public void sendPrintJob()
if(job == null)
System.out.println("No printers were detected");
else
// tell the job to use this object to request print pages
job.setPrintable(this);
job.setJobName("Site Panel Print Job");
loadAttributes(); // this fails
// display print dialog
if (job.printDialog(attributes))
// user pressed OK
System.out.println("Sending print job...");
saveAttributes();
// try printing
try { job.print(attributes); }
catch (Exception e) { System.out.println(e); }
System.out.println("Done.");
loadAttributes(); // this works fine

HI,
I am facing the same problem with the serialization of the HashPrintRequestAttributeSet object. Just wondering if there have been any updates or resolutions to this problem?Hi,
Please don't resurrect old threads. I'm locking this one.
Create a new thread with a specific question, and a good description of what you are trying to do.

Recieving cannot resolve symbol symbol : class Serializable
I'm receiving the error:
cannot resolve symbol symbol : class Serializable
The class is as follows:
//package cscie160.hw5;
import java.io.Serializable
* @author Eddie Brodie
* @version %I%, %G%
public class AccountInfo implements Serializable
public int _accountNumber;
public int _pin;
public AccountInfo(int accountNumber, int pin)
_accountNumber = accountNumber;
_pin = pin;
I've tried importing java.*
I've also checked my classpath.
Any ideas?Try taking the import statement out of the comment block; that might help

Trying to understand serialization basics
im getting a error messege in my test class
file load errorjava.lang.ClassCastException: java.lang.String
why would i be getting java.lang.string as a error if im trying to return a object
the load methods not working right but it seemed to save fine
can anyone tell me what im doing wrong
heres my full test applet
import java.util.Vector;
import java.io.*;
// ill serialize a vector here
public class SerilizationUsage extends Frame implements Serializable
Vector v = new Vector();
Vector vec;
A a;
int currentelement =0;
public SerilizationUsage(){
a = new A();a.value = 2;
v.addElement (a);
a = (A) v.get (currentelement);
System.out.println("v "+currentelement+"th elements value "+a.value);
save();
load();
public void save(){
try{
FileOutputStream out = new FileOutputStream("thevectordata");
ObjectOutputStream s = new ObjectOutputStream(out);
s.writeObject("v");
s.flush();
}catch (Exception e) {System.out.println("file save error"+e);}
public void load(){
try{
FileInputStream in = new FileInputStream("thevectordata");
ObjectInputStream s = new ObjectInputStream(in);
vec = (Vector)s.readObject();
}catch (Exception e) {System.out.println("file load error"+e);}
public static void main(String args[]){
System.out.println("Starting App");
SerilizationUsage f = new SerilizationUsage();
System.exit(0);
class A{
int value;
public A(){value = 1;}
}ah wait i didnt see i put "v" instead of v but now its giveing me a not serializable error
file save errorjava.io.NotSerializableException: A
file load errorjava.io.WriteAbortedException: Writing aborted by exception; java.io.NotSerializableException: A
