Getting java.io.NotSerializableException: sun.management.MemoryPoolImpl
Hi,
While trying to get JVM Memory pool information of a remote computer ,am getting java.io.NotSerializableException. I used following method
ManagementFactory.getMemoryPollMXBean().
Please help me to solve these exception.

I agree, it looks frustrating. Obviously the serialization process has found the non-serializable object during the traversal of the object graph, but its difficult to know where this is.
Your class looks a bit "serialization-heavy", if you don't mind me saying. I avoid serializing anything to do with swing components and stick to collections and my own classes. Do you need to serialize these? If not, mark them transient. You can do this for all of them and then reintroduce into the serialized form one at a time to see which one causes the problem (just for curiosity).
When the object is deserialized you will have to make the necessary arrangements to set up any members that you marked transient, as these will be null. You can do this is readObject, but on this subject, why are you writing out the points member explicitly? It will be written out anyway since there is nothing special about it.
I don't know how familiar you are with the serialization package but its a sharp instrument that needs respect. I would advise reading the specification, if you haven't already done so.

Java.io.NotSerializableException: sun.awt.image.BufferedImageGraphics2D
Hi all!
This problem is in relation to a very complex bean for data visualization which is jarred and bridged as an activex control.
I am able to create the activex control and embed it in a vb form. But when I try to run the application in vb I get the following message and the application does not start.
java.io.NotSerializableException: sun.awt.image.BufferedImageGraphics2D The bean has not used the class mentioned above anywhere. It uses the
Image
class though. I have used other beans, which use the same drawing techniques as the bean in question, as activex controls, with no errors.
What could be the problem?

PS: the actual error dump is 1 page long I can send it by email on request.Hello,
Have you implemented the Serializable Interface? I usually receive that error when I forgot to implement that interface. It is mandatory for a JavaBean to implement this interface.
As an example:
import java.io.Serializable;
public class SimpleBean implements Serializable
I hope it helps.

..... abbreviated
I can figure out the reason being that something inside the _Spline class is not serializable but I've checked everything and it seems fine. All custom classes implements Serializable.
Is there anyone who can give me a hint on what to look for? Is the sun.java2d.SunGraphics2D connected to any Swing component?
Your reply highly appreciated.

Java.io.NotSerializableException WHY??? What did I do??? ;-)
Hi Guys,
I am getting java.io.NotSerializableException when running a query and
passing in PersistenceCapable object via executeWithMap or
executeWithArray. When I run the same query and pass the object in
directly into execute()(as a single parameter), it works just fine... ???
I am using Kodo version 2.4.2. To pass the parameters in I have tried
HashMap as well as normal array (ArrayList.toArray()) and always got the
problem.
The code and full stack is bellow. Please note the test for
PersistenceCapable. Part of the code is commented out, but it still throws
the exception as it is.
Any help would be greatly appretiated!!!

who ever wrote it, mapped executeWithArray and executeWithMap to simple
Query.execute.
Damn! :-(

Hi Guys,
I am getting java.io.NotSerializableException when running a query and

executeWithArray. When I run the same query and pass the object in
directly into execute()(as a single parameter), it works just fine... ???
I am using Kodo version 2.4.2. To pass the parameters in I have tried
HashMap as well as normal array (ArrayList.toArray()) and always got the
problem.
The code and full stack is bellow. Please note the test for
PersistenceCapable. Part of the code is commented out, but it still throws

Any help would be greatly appretiated!!!

Java.io.NotSerializableException: com.sun.xml.tree.XmlDocument
Hi,
I got this error when my servlet is trying to parse a xml document:
RuntimeRemoteException( java.io.WriteAbortedException: Writing aborted by exception; java.io.NotSerializableException: com.sun.xml.tree.XmlDocument )
And my application runs ok when Tomcat is used as servlet container, but it runs into problem when iPlanet is used.
Any idea?
Thanks in advance!Thanks for your reply.
The EJBs in the application are all stateless beans. The error happens at the servlet side, not the EJB side. When the servlet tries to parse the returned XML document using xalan 1.0, the error happened. However, I can not reproduce the error when I use Tomcat as servlet container.
here is how I coded:
XSLTProcessor processor = XSLTProcessorFactory.getProcessor(new org.apache.xalan.xpath.xdom.XercesLiaison());
XSLTInputSource xmlSource = new XSLTInputSource(doc);
XSLTInputSource xslSheet = new XSLTInputSource("file:"+xslFile);
Writer out = new StringWriter();
XSLTResultTarget xmlResult= new XSLTResultTarget(out);
processor.process(xmlSource,xslSheet,xmlResult); -
Java.io.NotSerializableException: weblogic.ejb20.internal.EntityEJBContextImpl
Hi,
We are currently in the process of moving from Weblogic 6.1 SP5 and
Toplink 3.6.3 to Weblogic 8.1 SP2 and Toplink 9.0.4 and during some test
I have seen a "scaring" stack trace. It seems that, for some reason, a
thing that "uses to work" failed with a very strange error. I tried to
reproduce it but without any success. Besides asking if anybody knows
what could have caused this error I would like to know what the "not
serializable" object is. Is it the EntityEJBContext?

In case it could share some light in the case I will explain a bit what
does the process intended to do:
The general idea is that, given some data (managed with Toplink's 9.0.4
CMP) we take a XML "snapshot" of them (via a custom OBJ2XML class that
has been working for ages without any problem) and "publish" it via JMS
in order to perform asyncronous actions with it. I'm sure this is a,
more than usual, scenario for a lot of folks.
As it seems looking at the stack at some point during some internal
object serialization it fails and rollbacks all the process. The object
being serialized by our side only contains four attributes: a
java.math.BigDecimal for it's primary key, a java.util.Date for
timestamp locking and two simple java.lang.String's
Although I'm pretty sure the problem should not be with the entity bean
itself but with an internal Weblogic op (is it trying to serialize the
EntityBeanContext as stated after the java.io.NotSerializableException
message?
Any help with this would be greatly appreciated as I have no clue how
this happened and I'm also unable to reproduce it (I'm also sure if I
managed to trigger it testing the application alone it will rise many
more times that could be admited if we move to production).
I would like to point also that currently until we have some more time
to fix it we are using "remote" entity bean, I mean even if we are alway
s calling them within the container they are not deployed with "local"
interfaces yet (although AFAIK Weblogic should avoid RMI calls on them
being co-located with the session beans).
Regards.
Ignacio.

>Ignacio,
6.1 used pass-by-reference by default, so parameters to beans were
passed by reference.
It's very likely that you are getting this error because in 8.1 this default
was turned off. This causes serialization of parameters by default and
that's why your code that worked started failing - you just did not know
that you were passing non-serializable objects around.
To fix this you could either turn on the pass-by-reference explicitly and/or
find out where your code is passing non-serializable objects. This is a useful
exercise anyways.
Hope this helps.

Slava Imeshev

Java.io.NotSerializableException error when starting 8.1 app server
I am running JES 054Q with uwc deployed on the app server 8.1 (along with am, portal, and da). I am getting a java.io.NotSerializableException for com.sun.uwc.common.util.UWCPreferences when the application server starts. Any access to get attributes from UWCPreferences results more java.io.NotSerializableException errors. How do I get the app server to not load com.sun.uwc.common.util.UWCPreferences as Serializable?
Following is what is showing up the log file with finest level:

ThanksI think this might occur if you don't have the patch for SunAlert 46042 installed. There's more information on this critical Solaris security vulnerability, which was reported back in 2002, at http://sunsolve.central.sun.com/search/document.do?assetkey=1-26-46042-1
Can you run the following command to check if you have patch 109326-09 installed and let us know the result?showrev -p | grep 109326If you don't have 109326-09 or higher installed, you should install it as soon as possible. You can follow the link from the SunAlert. Better yet, install the latest Solaris 8 recommended patch cluster from http://sunsolve.sun.com/pub-cgi/show.pl?target=patches/patch-access to make sure your system is fully patched and up to date. -
Coherence POF java.io.NotSerializableException on standalone Webcenter spaces server.
Hi,
I’m using coherence(V3.6.1) with POF serialization in ADF web application. I have setup local coherence server node and Jdev integrated webcenter server in my local system(windows 7 OS), the application works perfectly when I run in local Jdeveloper integrated server. But when I deploy the application on dev environment ( standalone webcenter spaces server v11G on Unix OS) we are getting exception “(Wrapped) java.io.NotSerializableException: com.enbridge.co.ux.coherence.pojos.CommodityPojo”
It seems that POF is not configured properly on the standalone webcenter (spaces) server, please help finding out the solution for this issue. On standalone webcenter spaces server is there any extra configurations we have to do?
The error logs and configuration filess I have used:

Cant launch SunMC windows JAVA console under Sun VirtualBox 2.0.0
Hi,
Has anyone managed to successfully launch the Java console under Sun VirtualBox?
I'm using SunMC 3.6.1, Mac OS X 10.5.4 and Sun VirtualBox 2.0.0
When I attempt I get the usual messages
"Connection establish. Authenticating user"
"Login Successful. Launcing console'....but the console never displays.
Any thoughts?
DomAll of this was in fact related to the IP address changing (still not sure why a modified HOSTS file didn't fix?).
As a test, I removed "use DHCP" and hard coded my network connection back to the address it was when I first installed. While I did in fact lose internet connectivity, EM and the Listener could then fire up.
Obviously this won't be my permanent solution, but I wanted to post back for others with these issues. -

The stack trace sesms to tell me that it is something internal to the workshop generated EJBHome class since i do not see any reference to InitialContext in my bean class.
Is it some bug with workshop. Or is it something wrong i am doing.
Thanks
sriramPage 325 (paragraph 5) of O”Reilly Enterprise Java Beans (4th Edition) states:
“During the lifetime of a stateful session bean, there may be periods of inactivity when the bean instance is not servcing mentod from the client. To conseve resources, the container can passivate the bean instance by preserving its conversation state and evicitin the bean instance from memory. A ben’s convesatin stat may consist of primitive values, object that are serializable, and the following special types:
javax.ejb.SessionContext
javax.ejb EJBHome
javax.ejb EJNObject
javax.ejb Jta.UserTRansaction
javax.ejb Naming.Context(only when it references the JNDI ENC)

Java.io.NotSerializableException: java.awt.BasicStroke - really confusing
I have a class Box which has two member Size and Location, both Serializable.
Then I have several classes (e.g. Node) which extend Box.
None of all the classes (Box, Size, Location and all extensions of Box e.g. Node) use BasicStroke. I commented out the import of BasicStroke in all classes that are Serializable, so it cannot be used anywhere.
The problem is I use drag and drop, and when Box is also Serializable I get the following error when trying to drop:

I do not know how to better describe the error, because I have no clue why BasicStrokes is tried to serialize at all. I am really confused, but perhaps somebody has seen something similar and can give a hint.

kudiThanks for the hint. Actually I must say once more that I was too tired that I have overseen a memeber field because of bad code layout :-( I better went to sleep...
But there is still something confusing, that is also the reason why I did not search for the fields in the right class.
So I have a class Box and a class Node which extends Box. Node is the one which contains the evil AWT references. When I declare only Node as Serializable, it works. But when I also declare the super class Box as Serializable the error occured.
In my opinion a Serializable sub class with a super class which does not implement Serializable does not make sence, but as an accident I did it. What is the semantic in such a case? (At least I know it could not serialize the sub class as expected...)

Java.io.NotSerializableException when overwrite the JTable data into .txt file
hi everyone
this is my first time to get help from sun forums
i had java.io.NotSerializableException: java.lang.reflect.Constructor error when overwrite the JTable data into .txt file.
At the beginning, the code will be generate successfully and the jtable will be showing out with the data that been save in the studio1.txt previously,
but after i edit the data at the JTable, and when i trying to click the save button, the error had been showing out and i cannot succeed to save the JTable with the latest data.
After this error, the code can't be run again and i had to copy the studio1.txt again to let the code run 1 more time.
I hope i can get any solution at here and this will be very useful for me.
the following is my code...some of it i create it with the GUI netbean
but i dunno how to attach my .txt file with this forum
did anyone need the .txt file?
this is the code that suspect maybe some error here
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
String filename = "studio1.txt";
try {
FileOutputStream fos = new FileOutputStream(new File(filename));
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(jTable2);
oos.close();
catch(IOException e) {
System.out.println("Problem creating table file: " + e);
return;
System.out.println("JTable correctly saved to file " + filename);
}the full code will be at the next msgthis is the part 1 of the code
this is the full code...i had /*....*/ some of it to make it easier for reading

Java.io.NotSerializableException exception in session beans
Hey experts,
I have written the following code to call a session bean method from a portal application.
Object obj1 = context.lookup("applications/knet");
UserInfoHome userInfoHome =
(UserInfoHome) javax.rmi.PortableRemoteObject.narrow(
obj1,
UserInfoHome.class);
UserInfo userInfo = userInfoHome.create();
Collection col =
userInfo.getAllrooms();
out.println("The size is " + col.size() + "<br>");
The following is the implementation of the getAllrooms() method in the session bean
public Collection getAllrooms() {
Collection col = null;
try {
InitialContext ctx = new InitialContext();
roomsHome = (RoomsLocalHome) ctx.lookup("java:comp/env/ejb/RoomsBean");
col = roomsHome.findAllRooms();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FinderException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return col;
In the entity bean the following EJB QL has been used
<EJB QL>
select object(r) from Rooms r
</<EJB QL>>
I get the following error
com.sap.engine.services.rmi_p4.exception.P4BaseRuntimeException: I/O operation failed : java.io.NotSerializableException: com.sap.engine.services.ejb.entity.finder.EJBLocalCollection :

Please helpHi Sabbir,
You are trying to expose a Collection of Entity local interfaces (RoomsLocal) that is the result of RoomsLocalHome.findAllRooms(), through the Session bean's remote interface method getAllrooms(). This is forbidden by the EJB specification and of course cannot work. You have to use remote interfaces of Entity beans when you want to expose them to remote clients - although this is not a good practice either since Entity beans are fine-grained components. Data transfer objects (<a href="http://en.wikipedia.org/wiki/Data_Transfer_Object">DTO</a>) with Session facades should be used for this purpose (you already have a Session facade - the UserInfo bean).
Hope this clarifies it!

Java.io.NotSerializableException in WL6
All,
I have a servlet calling a user/group manager stateless session bean.
The same code works well in WL5.1.0.
Recently I migrated to WL6 and found there is a serialization problem.
Rebuild the EJB jar with WL6 ejb
compiler did not solve the problem. Here is the detail:
In the remote interface I have a method called assignGroups().
public interface InfUserGroupManager extends EJBObject {
public void assignGroups(InfIIPSession session, InfDBObjectPK userPk,
Collection groupIds)
throws RemoteException, InfInsufficientPrivilegeException;
In a servlet I have code like this:
InfUserGroupManager mgr = ....; // Gets a reference to InfUserGroupManager
stateless session bean.
HashMap groups = .....; // Both keys and values are java.lang.Integer
objects.
Collection assignedGroups = groups.values();
mgr.assignGroups(iipSession, userPk, assignedGroups);
java.util.HashMap and java.lang.Integer are both serializable. However, when
trying to invoke the
assignGroups() method on the InfUserGroupManager object will raise
exception.
javax.servlet.ServletException: failed to marshal
public abstract void
com.informatica.security.manager.InfUserGroupManager.assignGroups
