Deserializing a string
I need help with deserializing a string. The string looks like
FirstName1
LastName1
Address1
FirstName2
LastName2
Address2
FirstName3
LastName3
Address3
I want to deserialise this string into an array of person objects.
Thanks in advance.
J2ME does not support deserialize.
Create a format like below one
<firstName?lastName?address>
you encrypt your information in this formatted String. After that you can call getBytes() method it will give byte[]. you can store this byte array into recored Store (setRecord in RMS).
Whenever retrieve you can get byte array ,pass byte array to string constructor than you can get you information in above format.

I need to send Obj A but not Obj B which is referenced
I'm having a problem with my serialization. Here's the set up:
The server creates an instance of Obj A and Obj B, which contain references to each other. I want to serialize Obj A and send it to the client, but not Obj B.
First I tried setting Obj A's reference of Obj B to null right before I sent it to the client, but I kept getting Null Pointer Exception.
Then I tried adding "transient" to Obj A's reference to Obj B, but now when Obj A appears on the client, the other fields are also blank. I assume this is because Java is ignoring Obj B and all of it's references including Obj A.
Is there some way to void Obj A's reference to Obj B right before it's sent, without nulling Obj B completely?
Thanks!
MattThen I tried adding "transient" to Obj A's reference to Obj B, but now when Obj A appears on the client, the other fields are also blank. I assume this is because Java is ignoring Obj B and all of it's references including Obj A.No. Something wrong here. Make objB transient in objA, and send objA. Everything else in objA should appear at the client. That's how I thought it should work, which is why I tried it in the first place...
Is there some way to void Obj A's reference to Obj B right before it's sent, without nulling Obj B completely? Setting objA.objB to null doesn't 'null objB completely'. It does nothing to the object B, only to A's reference to it.
That's what I thought, but it again it didn't work, so I guess I then wrongly assumed that it was nullying Obj B (which doesn't really make sense, and of course it's wrong).
Ok here's the object I serialize and send:
public class Info implements Serializable{
Client clientInfo;
String cmd;
ArrayList<String> handleList = new ArrayList<String>();
ArrayList<Territory> list = new ArrayList<Territory>();
some methods....Then there's the Client class, which is where the problem is (Obj A from my first post)
public class Client implements Serializable {
public int ID;
String handle;
public ClientThread threadName;
public int money;
public ArrayList<Territory> ownTerrList = new ArrayList<Territory>();
public ArrayList moveList = new ArrayList();
public ArrayList attackList = new ArrayList();
public ArrayList buildList = new ArrayList();
some methods....Then the ClientThread class (Obj B from my first post), which is what's causing the problems because I think it cannot be serialized because it's a thread, is that correct?
Notice that the Client class above contains a reference to ClientThread threadName, which is the corresponding instance/thread of the class below, which contains a reference to the Client class above, Client client (so Obj A has a reference to Obj B and Obj B has a reference to Obj A):
public class ClientThread implements Runnable, Serializable{
Client client;
Socket connection;
String msg;
ObjectInputStream objIn;
ObjectOutputStream objOut;
Info courier = new Info();
C2Server server = null;
public ClientThread(Socket connection, C2Server server, int id){
this.server = server;
this.client = new Client();
this.client.ID = id;
this.connection = connection;
this.client.threadName = this;
server.addClient(client);
a run method...
some other methods....
My normal procedure for sending the information across the network is:
1) Update the Client instance which is inside the Info instance, which is the object sent.
2)Send
Then I started getting errors and problems so I started doing this:
1)Update the Client instance which is inside the Info instance, which is the object sent.
2) Set the Client instance's reference to the ClientThread instance to null (threadName =null)
3) Send
When the Info instance "gets" to the other side and is deserialized, the String cmd and ArrayList handleList are intact, but the ArrayList list and ArrayList ownTerrList (inside the Client instance) are both empty. I know those ArrayLists are full before I send because I do a System.out.println on them and they print out correctly with objects for each of my threads. They are full on the server side, then empty on the client side, and I can't figure out what the problem is. What might cause some of the fields in an object to be deserialized incorrectly while others are fine?
Thanks.

How to fix a problem with the order of strings in a JSON response for a CFHTTP request?
Good morning, guys! (It's 10:50 a.m. in Brazil)
First of all, I'm still new at CF and my questions may seem too much silly and my English's not the best, so, please be patient with me. hehe
Well, I'm accessing a link via CFHTTP that gives me a JSON response. I'm not familiar with JSON yet, so I'm working it as a string and using string functions (Find,RemoveChars,Replace,etc), but it happens to me that I'm receiving a certain kind of order of the strings list from the JSON when I access it directly from the browser and other kind of order totally different when I access it from the CFHTTP.
I only figured it out because I was working at home with my code and there everything went just fine as expected. Then I brought to my job to develop a little bit more as soon as I get a free time and here my code doesn't work anymore. When I took a look at the JSON by a CFOUTPUT, I realized the strings were in a different order.
Does anyone know why is it happening?
Link to the JSON: http://sigmine.dnpm.gov.br/ArcGIS/rest/services/extra/dados_dnpm/MapServer/0/query?text=83 0620/2012&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelInter sects&where=&returnGeometry=true&outSR=&outFields=FID,Shape,PROCESSO,ID,NUMERO,ANO,AREA_HA ,FASE,ULT_EVENTO,NOME,SUBS,USO,UF&f=pjson
Basic code simplified to find out that the order of strings were coming different when access by CFHTTP:
<cfhttp url="#URLAbove#" method="get" result="DadosDoDNPM" charset="utf-8" timeout="10000" />
<cfset DadosJSON = deserializeJSON(DadosDoDNPM.FileContent) />
<cfif arrayLen(DadosJSON.features)>
<cfset CodigoFonteJSON = ToString(serialize(DadosJSON.features)) />
<cfoutput> #CodigoFonteJSON# </cfoutput>
</cfif>
Is there a way to fix it and to make my code work everywhere?
If it matters, I use Railo at home and at my job.
Since now, I thank you.When you deserialize JSON data, ColdFusion converts it into native structures and arrays (roughly equivalent to JavaScript objects and arrays). In ColdFusion, structures are unordered (that is, they don't maintain keys in any particular ordered sequence).
This really shouldn't be a problem though, at least not if you just want to work with the data contained in the deserialized JSON structure. So DadosJSON should be a native ColdFusion structure, and you can interact with it like any other structure in ColdFusion. In fact, you should not have to re-serialize it at all unless you need to send it to an external application using JSON.
Why are you reserializing the data? And why use serialize() instead of serializeJSON()?

How to get XMP MetaData as an XML String in a process?
Hi there,
I have a process where I would like to export a documents XMP MetaData, manipulate the XMP MetaData and then import the MetaData again to the document.
I thougt first I will use the service Name "XMPUtilityService" with the Service Operation "Export XMP" to export the XMP MetaData as a document.
Hoewer I am not sure how to manipulate the output document from the Export XMP service.
When I print out the document.toString() in a execute Script Service I get the following:
<document state="active" senderVersion="0" persistent="false" senderPersistent="false" passivated="false" senderPassivated="false" deserialized="false" senderHostId="null" callbackId="0" senderCallbackId="0" callbackRef="null" isLocalizable="true" isTransactionBound="false" defaultDisposalTimeout="600" disposalTimeout="600" maxInlineSize="65536" defaultMaxInlineSize="65536" inlineSize="3440" contentType="null" length="-1"><cacheId/><localBackendId/><globalBackendId/><senderLocalBackendId/><senderGl obalBackendId/><inline><?xpacket begin="" id="W5M0MpCehiHzreSzNTczkc9d"?>
<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="A...</inline><senderPullServantJndiName/><attributes/></document>
Actually I expected something like this:

What do I need to do to get the XMPMeta data as an XML String from a document within a process?
Thanks in advance!
PaulHi,
thanks for the answer.
I know that I can retrieve the XMPUtilityMetadata object, but this object provides only access to a few information suche as creator, subject, producer, etc.
However I would like to retrieve the whole XML String of the XMP Metadata.
How is this possible?
Thanks.

[java.nio] StreamCorruptedException when deserializing objects
Hello everybody!
I made a messaging (chat) program using java.io where all the client-server communication is done by serializing small objects. Now I would like to covert the server side to the NIO concept and I'm already struck. I successfully pass objects to the client and the client deserializes them, but only the first one! When it try to read the second it fails with a StreamCorruptedException.
Here�s a sample (testing) code. In the server run() method I first serialize a string, then get its byte array from ByteArrayOutputStream and in the loop periodically send this byte array through the channel. On the client side I just read the deserialized object.
Server run():
public void run() {
try {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(baos);
oos.writeObject("abcdefgh");
byte[] objectArr = baos.toByteArray();
baos.close();
oos.close();
ByteBuffer buff = ByteBuffer.allocate(objectArr.length);
buff.put(objectArr);
buff.flip();
while(true) {
selector.select();
Set keys = selector.selectedKeys();
for (Object o : keys) {
SelectionKey key = (SelectionKey)o;
if (key.isAcceptable()) {
ServerSocketChannel server = (ServerSocketChannel) key.channel();
clientChannel = server.accept();
if (clientChannel == null)
continue;
clientChannel.configureBlocking(false);
SelectionKey clientKey = clientChannel.register(selector, SelectionKey.OP_WRITE);
} else if (key.isWritable()) {
SocketChannel client = (SocketChannel) key.channel();
if (buff.hasRemaining()) {
client.write(buff);
} else {
buff.clear();
buff.put(objectArr);
buff.flip();
try {
Thread.currentThread().sleep(2000);
} catch (InterruptedException e) {
return;
} catch (IOException e) {
e.printStackTrace();
}Client run():
public void run() {
try {
soc = new Socket("localhost", 4000);
ObjectInputStream ois = new ObjectInputStream(soc.getInputStream());
while(true) {
Object d = ois.readObject();
System.out.println("data = " + d.toString());
} catch (Exception ex) {
ex.printStackTrace();
}At the second read I get a StreamCorruptedException.
Apart from this I would like some hints in how to implement the application with NIO. For example how can I tell the objects apart on the client side � should I send every time a byte array before the object, which tells the length of the next coming object? This is probably not a 100% bulletproof solution and presents additional data transfer?
Than you in advance!OK, I found a solution but I don't like it, because I don't understand it.
The ObjectOutputStream adds a header (4 bytes) to the stream - if I send the array with those four bytes I get an StreamCorruptedException. If I send the array without the header I also get a StreamCorruptedException: "invalid stream header".
If I reconstruct the object, by calling ObjectOutputStream.writeObject() and get it's byte array from ByteArrayOutputStream.toByteArray(), every time I have to fill the ByteBuffer, then it works.
Here's the modified sending block, for the above example:
} else if (key.isWritable()) {
SocketChannel client = (SocketChannel) key.channel();
if (buff.hasRemaining()) {
client.write(buff);
} else {
//* ---- added code ---------
baos.reset();
oos.writeObject("abcdefgh");
objectArr = baos.toByteArray();
buff.clear();
buff.put(objectArr);
buff.flip();
} I really don't understand why I have to write the object in the object stream every time. I used ObjectOS and ByteArrayOS, to get the object byte array and then I thought I could forget about those streams and use this array to fill the ByteBuffer. What changes if I send the object through this process with every iteration (and how this harms speed - it's like sending everything twice)? If someone would explain this to me I would appreciate it much. -
A very very strange issue on BlazeDS Deserializing
Hi all,
I run into a very very strange issue on BlazeDS Deserializing. Is there any hint or idea? Thanks a lot!
Scenario 1:
Both the browser(firefox or IE) and the midtier (BlazeDS ,java) are on the same machine.
Actual result:
Everything works fine. All the properties in the Flex Object could be mapped to the Java Class
Scenario 2:
The browser(firefox or IE) and the midtier (BlazeDS ,java) are on the different machine.
Actual result:
Sometimes it works fine.
And most of the time it does not work fine. Only the data in List is mapped correctly. All the values of simple data type such as int are mapped to 0 .
Let me simplify the problem.
The objects of Class B is always stored in the ArrayCollection assocItems of Class A
Flex side:
public class A {
public var id: int;
public var name: String;
public var assocItems: ArrayCollection=new ArrayCollection();
public class B {
public var id: int;
public var assocItems : ArrayCollection=new ArrayCollection();
The id , name in Flex Class A and assocItems in Class B could be deserialize to correct value . But the id of Class B is always mapped to 0. This is not correct.
The log level of BlazeDS is configured to Debug. From the log I can see that each value is passed from Flex side to Java server side correctly.
[BlazeDS][INFO] Channel endpoint my-amf received request.
[BlazeDS][DEBUG] Deserializing AMF/HTTP request
Version: 3
(Message #0 targetURI=null, responseURI=/18)
(Array #0)
[0] = (Typed Object #0 'flex.messaging.messages.RemotingMessage')
However, the Java object does not get the correct value of B.id.
In conclusion,
1. It’s an issue with only default types
2. It does not occur every time
3. It does not occur when the browser(firefox or IE) and the midtier (BlazeDS ,java) are on the same machine
Have you ever run into the similar problems? And what’s your solution?I checked, when I hard-code the constant in linq, the generated sql is like this:
SELECT "Extent1"."AA" AS "AA"
FROM (SELECT "TBL"."AA" AS "AA"
FROM "USERNAME"."TBL" "TBL") "Extent1"
WHERE ('1062303212007000121' = "Extent1"."AA")
if I pass a variable to the query with same value, the sql is like this:
SELECT "Extent1"."AA" AS "AA"
FROM (SELECT "TBL"."AA" AS "AA"
FROM "USERNAME"."TBL" "TBL") "Extent1"
WHERE ("Extent1"."AA" = '1062303212007000121' /* @p__linq__0 */) (@p__linq__0 is passed as parameter)
The only difference is a paramter. I can't figure out why there is such a impact on performance. -
Deserializing an XML to object in an RFC : HELP
The requirement in my project is that I pass the Serialized XML String to a Remote Function Module by calling the RFC. In the RFC, I need to deserialize the XML to corresponding class instances/Objects.
CALL TRANSFORMATION id
SOURCE XML i_xml
RESULT ref = O2 .
But this stmt throws an exception in d RFC stating
XML_INVALID_REF A non-existent objectID was referenced (property href).
I have no ideas of getting this work. Please help me if u have any information about it. Looking fwd.. U can as well mail me ur inputs to [email protected]
Thanks,
Srikanthi am not sure about deserializing xml ..check this blog ..it has some information about it..

Problems displaying deserialized components
I'm trying to save the state of some objects which extend JComponent and JLayeredPane, and they don't all redisplay on deserializing, although they seem to be in the containment tree.
Basically, I have a class GamePanel which extends JLayeredPane. Also classes Square and Region both of which extend JComponent and use 2D graphics for painting themselves. It seems to serialize OK (but how does one tell?). But when I deserialize, only the lower level of the GamePanel is painted. However, the higher level is populated.
Does anyone have any idea why they're not displaying? The code is below (TestKiller and its menus are generated by NetBeans - hence the slightly odd code). There are 5 menu items (I've simplified a lot from the original so it's a bit clunky): Add Region (you can only do this once in this version), Save As which serializes to a file, Restore which deserializes from a file, Exit which is obvious and Print which outputs the containment hierarchy of GamePanel to standard output.
If you want to try it out, fire up the program, do a File|Add to add a Region (see the dotted lines) and File|Print to see that there's a Square at level 2 and a Region at level 3. Then File|Save as... to save it. Quit the program.
Fire it up again and do a File|Restore and a File|Print. You'll see from the output that the Square and Region are there with identical parameters to the output before, but the Region hasn't displayed its outline.
The output's below, with java-like comments added to show what I've done:

Please someone tell me what I'm doing wrong. As a serialization newbie it's probably something simple, but no amount of validate() and pack() makes any difference.
The code's below - a bit long I'm afraid but it's difficult to cut it down much more and display the problem. The main class (TestKiller) was generated by NetBeans.

The version on 10.5 was supporting it." This means that it's our bug that we keep using Lucida Grande as fallback font even Apple dropped support Thai script with that font after 10.6. Unfortunately this bug was deferred from current development release (11.2) because of time constraint. If this support is critical for your business, can you open a bug in our public bugbase and ask as many vote as possible? In this way I may be able to convince internal team to fix this bug in next release.
Thank you for your feedback!

Error deserializing arguments, xml tag without a recognized type
I am trying to run a webservice created using Weblogic Workshop 8.1sp2 that communicates
with an ejb control. When I test in debug mode, I get the above error, specifically:
<detail>
<jwErr:jwErrorDetail xmlns:jwErr="http://www.bea.com/2002/04/jwErrorDetail/">
com.bea.wlw.runtime.core.request.RequestValidationException: Error deserializing
arguments.
Encountered an xml tag without a recognized type: the type must be declared with
an xsi:type attribute.
Caused by: com.bea.xml.marshal.XmlEncodingException: Encountered an xml tag with
out a recognized type: the type must be declared with an xsi:type attribute.
</detail>
I am passing a Request object to the jws method (to the ejb) that has a Collection
as an instance member. This Collection references objects of another type, Param
(code for both objects below). Before passing the object, I convert the Collection
to an array of objects. When I call the operation via a java client, I get the
above message.
In Workshop, I've included the Request and Param classes as the parameter xml
and the soap style is rpc. I've tested the ejb by itself and it is working fine.
Request.java:
import java.util.*;
public class Request implements java.io.Serializable
protected Collection params=null;
public Collection getParams()
{ return params; }
public void setParams(Collection data)
{ params=data; }
Param.java:
public class Param implements java.io.Serializable
private String name=null;
private Object value=null;
public String getName()
{ return name; }
public void setName(String data)
{ name = data; }
public Object getValue()
{ return value; }
public void setValue(Object data)
{ value=data; }
Here's the code from the jws:
public class MyWS implements com.bea.jws.WebService
* @common:control
private control.PSEjbControl psEJB;
static final long serialVersionUID = 1L;
* @common:operation
* @jws:parameter-xml
* include-java-types="mypackage.Request mypackage.Param"
* @jws:protocol soap-style="rpc"
public void addData(mypackage.Request arg0) throws java.rmi.RemoteException
System.out.println("arg0 : " + arg0);
psEJB.addData(arg0);
*Note: in the server console, arg0 comes through as null when called from my client.
Here's the bit from my client:
import weblogic.jws.proxies.*;
import org.openuri.www.encodedTypes.Request;
import org.openuri.www.encodedTypes.Param;
public void go(String wsdl) throws Exception {
MyWSSoap mw = null;
mw = new MyWS_Impl().getMyWSSoap();
Request req = new Request();
Collection reqColl = new ArrayList();
Param param1 = new Param();
param1.setName("NAME");
param1.setValue("Joe Tester");
Param param2 = new Param();
param2.setName("ADDRESS");
param2.setValue("345 Test Drive");
reqColl.add(param1);
reqColl.add(param2);
Object[] obs = reqColl.toArray();
req.setParams(obs);
mw.addData(req);
Not sure if this enough to go by. Please let me know if you need more information.
Any help is really appreciated. Thanks.Hi Keith,
My only suggestion is to factor out the java.util.Collection (see the
docs here [1]) with either primitive types or XMLBeans [2].
Sorry, not much help. You might also ask your question in the workshop
[3] newsgroup.

Hi Bruce, thanks for the reply. I set the operation for document-style soap and
still get the deserialization exception as mentioned in my original note. Below
is the wsdl. Note: in my original note, the problematic operation was addData()
which is now named addBusinessLocation(). As always, your help is greatly appreciated.

Hi Keith,
As a quick test, you might try changing the protocol style to use
doc/lit (@jws:protocol soap-style="document") to see if this provides
another view on the real issue.
Could you post the generated WSDL?
Thanks,
Bruce

ClassNotFoundException deserializing
I am having an strange problem: in a servlet, when I serialize and then deserialize it's session I happen to get:
1.- Serialization and Deserialization goes OK when session has no attributes;
2.- Serialization and Deserialization goes OK when session has only attributes of type in JDK;
3.- Serialization goes OK but Deserialization goes NOT OK when session has attributes from custom classes;
The following servlet code and custom object code exemplify this behaviour. I am using WebLogic 8.1 SP4. It all happens regardless of archived or exploded deployment, and also in standalone or clustered instances. It also happens regardless of wether session is replicated or not.
Any help or clue about what is happening or what I am doing wrong would be appreciated. To test it, you only need to deploy the following objects onto any existing or new web app. Then, the catch block with comment <i>// this code will be executed :o(</i> will be executed...
Thank you in advance.

Elements Type lost when deserializing a collection in Flex
I am running FlexBuilder, BlazeDS, SBI (Spring Blaze Integration), Hibernate with Tomcat 6 on a local machine.
I have a layoutStructure object that holds layoutModule objects in its layoutStructure.children ArrayCollection. On the server LayoutStructure.java contains a List<LayoutModule> children collection annotated OneToMany to the LayoutModule table. I can see in the BlazeDS debugger that the List<LayoutModule> being sent from the server correctly contains LayoutModule objects but when it is being deserialized in Flex all of them lose their type and are translated into Object type.
Can anyone please let me know why do you thing that is? I have all the [RemoteClass(alias=" ... ")] mappings correctly done. Here is some of the code (omitting all the packaging information):
LayoutStructure.java:
@Entity
@Table (name="layoutstructure")
public class LayoutStructure implements Serializable
private static final long serialVersionUID = 8935662122890799233L;
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="layoutStructureId")
public Integer id ;
@OneToOne(
cascade=CascadeType.ALL,
optional=false)
public User user;
@OneToMany(
fetch = FetchType.EAGER,
cascade = CascadeType.ALL )
@JoinColumn(
name = "fk_layoutId",
nullable = false )
@org.hibernate.annotations.IndexColumn(
name = "position")
public List<LayoutModule> children ;
LayoutModule.java:
@Entity
@Table (name = "layout_module")
public class LayoutModule implements Serializable
private static final long serialVersionUID = -4413201380054375907L;
* NanToNullProxy() needed in order to null out the id:Number
* property coming from Flex in a newly created object (it
* defaults to NaN in Flex but I need it NULL for Hibernate
* to persist it as a new object).
public LayoutModule(){
BeanProxy bp = new NanToNullProxy();
bp.setIncludeReadOnly(true);
PropertyProxyRegistry.getRegistry().register(LayoutModule.class, bp);
private Integer id;
@Id @GeneratedValue( strategy=GenerationType.AUTO )
public Integer getId() {
return id;
public void setId(Integer id) {
this.id = id;
LayoutModule.as:
[Bindable]
[RemoteClass(alias="test.layout.LayoutModule")]
public class LayoutModule extends EventDispatcher implements IUID
* The id number to store in the database.
public var id : Number ;
* Unique Id needed for proper identification
* in the tree component when it is being
* reopened to the same LayoutUnit after refreshing
* the dataProvider.
public function get uid():String
return String(id) + "c";
public function set uid( uid:String ):void
Any help would be greatly apprectiated. Thanks. Dahn.Hi DJ
Thanks for the quick reply.
The good news is that what you suggest simplifies my process a lot. So thanks for that.
The bad news in the order in still wrong. I.E it's not as the collection order, but it is the same order as the Process Multiple file route!
So a step forward, but not quite there yet.
Thanks so far!

Hashtable imcompletely deserialized?!
If anyone could help me with this I would be most appreciative.
I appear to have a situation where a serializable class with an internal Hashtable is not deserilizing correctly. The class containing the Hashtable is called PropDb. In PropDb I have this method...
protected Hashtable m_names = new Hashtable();
public synchronized String getStringVal(String key) {
if ((key != null) && (key.length() != 0))
return (String)m_names.get(key);
else
return null;
}Now here is the exception that is sometimes thrown...
java.lang.NullPointerException
at java.util.Hashtable.get(Unknown Source)
at util.PropertyDB.getString(PropertyDB.java:635)Given that the key is not null, and looking at the source for Hashtable... the only other entities in Hashtable.get() that could throw the NullPointer are the internal data array or one of the data items in the data array!
The reason I'm suspecting the serializing/deserializing is because it this NullPointer seems to come up "randomly"-- often enough to be a problem, but with no identifiable pattern!! So, can anyone tell me there are know issues with Hashtables deserializing in an incorrect state?
Thank you very much.Hi there,
I just wanted to mention that Hashtable's actions are strongly
dependent by the hashcodes of the keys. Let's say that your
KEY objects don't have constant hashCodes. Then the result of
get() method is often wrong 'cause of the formula
int hash = key.hashCode();
int index = (hash & 0x7FFFFFFF) % tab.length;
So if you want to serialize /deserialize Hashtable , I recommend you
to override the hashCode() method of you Keys and write it in a way
that gives you assurance that your key's hashcodes will remain constant after serialize/deserialize

JMS getObject() Error deserializing object for client
I am using WL6.1 and having a problem deserializing an object for a
client that doesn't have access to the corresponding implementation
object in its CLASSPATH (it only deals with the interface). From
previous posts, I read that upgrading to SP3 would fix this issue, but
I am still having this problem on both Solaris and Windows using SP3.
If I modify the client CLASSPATH to include the Server-side JAR file
that contains the implementation class, I don't have the problem and I
can successfully perform getObject() and deserialize the object. The
following is the code for the client:
public void onMessage(Message msg)
String msgText;
if(msg instanceof ObjectMessage)
try
ObjectMessage objMsg = (ObjectMessage) msg;
ActivityCreationEvent msgEvent =
(ActivityCreationEvent) objMsg.getObject();
System.out.println("Got a creation event");
catch(Exception ex)
System.out.println("Error getting JMS message:" + ex);
ex.printStackTrace();
the following is the code for the server:
objMsg = tSess.createObjectMessage(null);
ActivityCreationEvent createEvent=new ActivityCreationEventImpl();
objMsg.setObject(createEvent);
tPublisher.publish(objMsg);
and the following is the client stack trace:

The client doesn't need to have access to the implementation class for
any other aspect of the code, and I would like to keep it that way.
Does anyone have information as to the cause of the problem and a
solution?
Thanks in advance
Hi James,
Just having the interface is not sufficient, as the JVM must be able to
find the implementation class of an object in order to unserialize it - this is not a WebLogic
thing, it is a java thing. Either package the required class in the .ear that contains
the MDB or put it in your classpath.

Serialize String containing only whitespace such as a " " character
I'm having dufficulty figuring out how to serialize a String property
[XmlElement("DescriptionDelimiter1")]
public String DescriptionDelimiter1
get { return _DescriptionDelimiter1; }
set { _DescriptionDelimiter1 = value; }
Granted, I don't really need the XmlElement tag but just in case I want to change the name of the XML element...
Anyway, what I get in XML is
<ImportProfiles>
<ImportProfile Name="HPH Import Profile">
<ConcatenateDescriptions>true</ConcatenateDescriptions>
<DescriptionDelimiter1 />
<DescriptionDelimiter2>\r\n</DescriptionDelimiter2>
<DescriptionDelimiter3>\t</DescriptionDelimiter3>
<ImportProfile>
</ImportProfiles>
The problem is when serialized, if the value is " " or a single space, the result is <DescriptionDelimiter1 /> which when deserialized sets the string's value to "" with is not the value I need. I've looked into using CData but there doesn't seem to be a simple way to implement it... I expect
<DescriptionDelimiter1> </DescriptionDelimiter1>
or
<DescriptionDelimiter1><[CDATA[ ]]></DescriptionDelimiter1>
Is there some setting I can use when serializing the object to indication the process should not trim away whitespace?
The following is the method used to serialize my object:
public static String Serialize(DataImportBase dib)
System.Type[] ArrType = new Type[1];
ArrType[0] = typeof(System.DBNull);
XmlSerializer xs = new XmlSerializer(typeof(DataImportBase), ArrType);
System.IO.MemoryStream aMemoryStream = new System.IO.MemoryStream();
xs.Serialize(aMemoryStream, dib);
return System.Text.Encoding.UTF8.GetString(aMemoryStream.ToArray());
Thanks for any assistance!!!
ChrisI have looked through the classes for XML serialization but I haven't found anything that seems to allow one to set that attribute xml:space declaratively on members.
One way to change the serialization behaviour would be to write a specialized XmlWriter that takes a list of element names for which it writes out the xml:space attribute. This can be done with a few lines if you use the XmlWrappingWriter from the project http://www.codeplex.com/Wiki/View.aspx?ProjectName=MVPXML. The code for XmlWrappingWriter is also shown in Oleg's blog.
If you use that then you can set up a specialized XmlWriter as follows:
public class XmlSpaceWriter : XmlWrappingWriter
private XmlQualifiedName[] ElementNames;
public XmlSpaceWriter(TextWriter output, XmlQualifiedName[] elementNames)
: base(XmlWriter.Create(output))
ElementNames = elementNames;
public override void WriteStartElement(string prefix, string localName, string ns)
base.WriteStartElement(prefix, localName, ns);
foreach (XmlQualifiedName name in ElementNames)
if (name.Namespace == ns && name.Name == localName && base.XmlSpace != XmlSpace.Preserve)
base.WriteAttributeString("xml", "space", "http://www.w3.org/XML/1998/namespace", "preserve");
break;
and use it like this
Foo foo = new Foo();
foo.Bar = " ";
foo.Example = " ";
XmlSerializer serializer = new XmlSerializer(typeof(Foo));
StringWriter stringWriter = new StringWriter();
XmlSpaceWriter spaceWriter = new XmlSpaceWriter(stringWriter, new XmlQualifiedName[] {new XmlQualifiedName("Bar")});
serializer.Serialize(spaceWriter, foo);
spaceWriter.Close();
string markup = stringWriter.ToString();
The result then looks like this:
<?xml version="1.0" encoding="utf-16"?><Foo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><Bar xml:space="preserve"> </Bar><Example> </Example></Foo>
The example code above has just one constructor for a TextWriter but the code could obviously easily extended to have further constructors taking e.g. a stream. -
Deserializing cyclic reference with object resolution
I am attempting to deserialize complex objects containing cyclic references with an ObjectInputStream that implements the method resolveObject.
Of course, enableResolve(true) has been called in the constructor of the object input stream.
The problem I am seeing is that object resolution, when applied, is not propagated back to those objects that have been already deserialized and point to a "handle" object.
Is there a proper way to retroactively enforce object resolution?
Cheers,
Didier H. BessetHi Didier
I read your code, downloaded junit and ran your test. The test fails, so back to a few System.out.println statements!
I put a few into your code, see attached. Your deserialization is OK but your getComposite method returns the underlying referent and you are testing against the SoftReference!
Here's the output of the printlns - you can see the strings, objects and lists being resolved and the final "test" of printing out the objects you are comparing.
