Non serializable class in biztalk

Is it possible to have a non serializable class in a biztalk application?
Christiane

Hi Christiane,
Yes, it can be used in orchestration but in an atomic scope only.
Steps to call a Non-Serializable .NET Helper Class inside an Expression Shape(The DLL that contains the class must be strongly signed and placed in the GAC):
1.Add a reference to that class.
2.Add an Atomic scope.
3.Create an Orchestration variable of that class inside the scope.
4.Create an instance on that object inside the scope.
5.Call the method.

URGENT : Pass non-serializable objects over sockets

I am working with a non-serializable class.I can't change it to serializable(since it's an API class).I can't create a subclass either as I need to pass the same exact Object .I have tried wrapping it in a serializable class (as transient )but then the particular object that I need is not serialized.Is there a way to pass non-serializable objects over sockets?.Some other way of doing this?. Should i use RMI or Externalize?. Any help would be appreciated.

{snip}
Like this:
public class SerializableLibraryClass extends
LibraryClass implements Serializable {
}Then you've got a class that is exactly the same as
LibraryClass, but is now serializable.Not quite. The base class still isn't Serializable. Take, for example, the following code:
public class A
public int a1;
public class B extends A implements Serializable
public int b1;
B beforeSend = new B();
beforeSend.a1 = 1;
beforeSend.b1 = 2;
objectOutputStream.writeObject(b);
B afterSend = (B)(objectInputStream.readObject());Both beforeSend and afterSend have fields a1 and b1. For beforeSend, a1 = 1 and b1 = 2. For afterSend, b1 = 2 but a1 = 0. The superclass wasn't Serializable; therefore, its members weren't Serialized and, when the object was created on the other side of the stream, a1 was left at its initial value.
In short, you can't just Serialize the subclass. That Serialization won't apply to its superclasses.

Have you considered leaving it in situ and using RMI to manipulate it remotely ?
To be a little pedantic, if you need the "same exact object" then there's no technique that will work for you, since you can only copy an object between JVMs, not move it.

XSQL-022 error on using FOP - serializer class not found; urgent!

Hi all,
currently using XDK 9.2.0.1.0. On trying to invoke Apache FOP serializer I just get the following error message:
XSQL-022: Cannot load serializer class oracle.xml.xsql.serializers.fopserializer
and I really don't know why....
Running XSQL Servlet within Tomcat 4 Engine, but error pops up using both, Tomcat way and/or just the commandline invoker xsql.bat.
Generally XSQL Servlet is working correctly.
My classpath setting contains:
xmlparserv2.jar; batik.jar; classes12.jar; fop.jar; fopserializer.jar; oraclexsql.jar; sax2.jar; xalan-2.0.0.jar; xalanj1compat.jar; xerces-1.2.3.jar; xschema.jar; XSQLConfig.jar; xsu12.jar
The serializer being redefined in XSQLConfig is just:
<serializer>
<name>FOP203</name>
<class>oracle.xml.xsql.serializers.fopserializer</class>
</serializer>
This is because of using FOP 0.20.3, so having my own serializer class due to API change in FOP 0.20.x; my fopserializer is looking like that:
package oracle.xml.xsql.serializers;
import org.w3c.dom.Document;
import java.io.PrintWriter;
import oracle.xml.xsql.*;
import org.apache.fop.messaging.MessageHandler;
import org.apache.fop.apps.*;
import java.io.*;
// FOP 0.20.3 Serializer implementation for XSQL
public class fopserializer implements XSQLDocumentSerializer
private static final String PDFMIME="application/pdf";
public void serialize(Document doc, XSQLPageRequest req) throws Throwable
try
Driver FOPDriver = new Driver();
FOPDriver.setRenderer(FOPDriver.RENDER_PDF);
MessageHandler.setOutputMethod(MessageHandler.NONE);
FOPDriver.setupDefaultMappings();
req.setContentType(PDFMIME);
FOPDriver.setOutputStream(req.getOutputStream());
FOPDriver.render(doc);
catch (Exception e)
e.printStackTrace(System.err);
In my XSQL file I'm using the following PI:
<?xml-stylesheet type="text/xsl" href="listemps.fo" serializer="FOP203"?>
Any suggestions what is wrong in here ?
Can't use the original xsqlserializer.jar either - same error.
Thanks in advance
Jochen

Hi Jochen,
I'm working with Tomcat 4.0.3, FOP 20.0.3 and XDK 9.2.0.1.0, too.
I've copied all the jar-files into tomcat/common/lib. I think that you can't use the MessageHandler in fop20.0.3. I'm using the following serializer:
package diva.xml.xsql.serializers;
import org.w3c.dom.Document;
import java.io.PrintWriter;
import oracle.xml.xsql.*;
import org.apache.fop.apps.*;
import org.apache.log.*;
import org.apache.log.format.*;
import org.apache.log.output.io.*;
import org.apache.avalon.*;
import java.io.*;
public class XSQLFOP203Serializer implements XSQLDocumentSerializer {
private static final String PDFMIME = "application/pdf";
private static final String CONFPATH = "/usr/local/fop/conf/userconfig.xml";
public void serialize(Document doc, XSQLPageRequest env) throws Throwable {
try {
// Open user config file
File userConfigFile = new File(CONFPATH);
Options options = new Options(userConfigFile);
// First make sure we can load the driver
Driver FOPDriver = new Driver();
// Setup logging
Hierarchy hierarchy = Hierarchy.getDefaultHierarchy();
PatternFormatter formatter = new PatternFormatter("[%{priority}]: %{message}\n%{throwable}" );
LogTarget target = null;
target = new StreamTarget(System.out, formatter);
hierarchy.setDefaultLogTarget(target);
Logger log = hierarchy.getLoggerFor("fop");
log.setPriority(Priority.INFO);
FOPDriver.setLogger(log);
// Then set the content type before getting the reader/
env.setContentType(PDFMIME);
FOPDriver.setRenderer(FOPDriver.RENDER_PDF);
FOPDriver.setOutputStream(env.getOutputStream());
FOPDriver.render(doc);
catch (Exception e) {
// Cannot write PDF output for the error anyway.
// So maybe this stack trace will be useful info
e.printStackTrace(System.err);
Hope this helps

Non-Serializable Parameter in client methods on an Application Module

Hello,
I want to create a client method which expects an java.io.InputStream as input parameter. Unfortunately all method parameters must be of a data type that implements the Serializable Interface. This might be good and reasonably for remote deployments as EJBs, but I want to use them local.
Is there any solution for this problem?
Thanks,
Christian

The use of our interface-based approach is for guaranteeing that your client layer is always separable from your middle-tier layer.
If you are implementing a project where you are making the assumption that you won't be separating the two, then you can:
(1) Make sure you're using Immediate sync mode, and
(2) Have your client downcast to your *Impl class to call your method with non-serializable parameter.
This isn't best practice in general, but given your constraints, it's the way to solve this problem.

Serialializing non serializable objects

Hi guys,
I have to serialize (and then send through socket) a class which implements java.io.Serializable. This class also has some reference with other classes, which should be serialized togheter.
But when I run the main class (which only serializes) , java.io.NotSerializableException is thrown.
How do I recognize if a class is effectively serializable?
How do I serialize too even with non-serializable objects?
(I need all these objects)
note : In the class I have only put the marker "implements java.io.Serializable",should I have to do somenthing else?
Thank You for your great help!

if generics are used.
To solve your problem besides the marker, implement
methods writeObject and readObject and serializing
the contained object that is not serializable by
hand. For example if your class is X which contains Y
that is not serializable then you need to serialize
fields Y in X.writeObject and construct a Y object in
X.readObject:
class Y { // not serializable and you cannot modify
it
int i;
int j;
Y(int i, int j)
class X implements Serializable {
String xyz;
Y y;
private void writeObject(ObjectOutputStream out)
throws IOException{
out.writeObject(xyz);
out.writeInt(y.getI());
out.writeInt(y.getJ());
private void readObject(ObjectInputStream in)
throws IOException{
xyz = (String) in.readObject();
int i = in.readInt();
int j = in.readInt();
y = new Y(i, j);Remember to maintain the same order in readObject and
writeObject.

Inserting non-serializable objects

Is there any way to insert non-serializable objects into a database? (Or to convert them to bytes?)

Is there any way to insert non-serializable objectsinto a database?
A joke right?No, it's not a joke. It would be a pretty bad one if it were.
Yes, there is a way. Create a table that corresponds
to the object where each attribute in the object
corresponds to field in the object. Add a unique key
if one doesn't exist.I wish it were that simple. I don't have access to those attributes...
>
To create an object insert a row into the table. To
load the object use the unique key to query for the
row. To 'delete' the object delete the row from the
table.BTW, the object in question is the java.awt.geom.Area object (http://java.sun.com/j2se/1.3/docs/api/java/awt/geom/Area.html ).
The only way I can think of to insert an object that doesn't map to a SQL type is to convert it to bytes through serialization, and insert it as RAW data.
I've extended Area to add a name and made my class serializable. However, since Area is not serializable, the only data I can retrieve after deserializing is the name I added (from my understanding of serialization, I have to save Area's data myself, but can't since I don't have access to it, so the deserialization process calls the Area() constructor which initializes the object to empty).

Non Serializable Objects

I am working on a java project and I have to serialize a class (created by me) which has many references to other classes that should be serialized too.
I add the marker "implements serializable" to all the necessary classes, but when I run I get a non serializable exception.
Maybe one ore more objects are non serializable, but how do I identify them?
I've read that If I have to serialize non serializable objects, I need to write my own writeObject(ObjectOutputStream out)throws IOException and readObject(ObjectInputStream in) , but I don't know how to implement and us them.
note : I can't use transient beacuse I need everything to be serialized!
Thanks a lot. Bye!

Now I'll post my code, If anyone knows how to serialize (and then deseserialize) the class "AgentMessage" , and its subclasses "StaticPart" and "DynElement" from the main class , I'll be grateful.. It's about 2 days I'm working on it and I continue getting "nonserialializable exception" ...
thank you guys

Non-Serializable objects in webservice

Hi everyone,
I'm writing a webservice that connects and performs update on a third-party
data repository (document management system) through the vendor provided
framework.
Some of the objects used in the framework are not serialized, and WebLogic
Workshop 7.0 won't compile my services because they contain non-serializable
objects. Those objects are not used as messages or method parameters, rather
are the member variables of the services.
My question is how would I go about using non-serialized objects in a
webservice class with WebLogic Workshop 7.0? I've seen some Apache AXIS
webservice examples that does the similar thing, but some of the services
works with non-serializable objects. Do I need to create an EJBcontrol that
masks non-serializable objects to be used with the webservice?
Any input is greatly appreciated. I'm still new at webservice programming.
Thank you,
Makoto

Custom non-PersistenceCapable classes used as keys in Maps and/or SortedMaps?

Hi all,
I need to support custom non-PC classes as keys in SortedMaps. It takes
custom coding to the Kodo API right now, and before embarking down that
road, I wondered if anyone out there has already done this and is willing
to share that code.
Thanks!
--matthew

Matthew-
Can you just make the key implement Serializable and store it as a blob
(which means that you will not be able to query against it), or do you
have other restrictions?

Object (which has non-serializable attr.) serialization

i could not solve object serialization problem in anyway. how can this be performed without "java.io.NotSerializableException"?

Hi,
No, transient means that the attribute won't be sent over the stream. You usually declare fields that you don't want to send, or can't send as transient.

11g 1.3 provides a new Serializable class warning ?

We have an adf swing app we moved to version 1.3
we now get this warning in most of the app classes:
Serializable class contains non-serializable fields: [contactX]
this is an example class as basic as you can get that extends JDialog and It uses another class. The warning wants to mark ContactX.class as transient ?
This should not require the "private transient" Keyword as it has nothing to do with Jdialog being Serializable.
Is this produced for some reason due to changes in use of the adf binding or
has something changed that could impact the application now or in the future or is this warning in error?
public class ContactXDialog extends JDialog {
private ContactX contactX;
}

Ok I think I understand your confusion better now.
- JDialog implements Serializable
- You extends JDialog, so ContactXDialog also implements Serializable
- Serialization implies the serialization of all fields, so contactX is a serialization candidate
- Now there's two possibilities.
1. contactX is calculable, meaning you can compute it back at runtime if needed, this is often the case of cached or lazy fetched values. Then you can make the field transient, effectively removing it from the serializable candidates
2. contactX must be set, then it must be serialized, therefore it must be Serializable as well. So the only option here is to have ContactX class implement the Serializable interface.
The warning offered the easiest way out, albeit likely a problematic one, to add the transient modifier.

Hi Wijk,
I have created java class with using NetBeans IDE .
and running with .NET client and i kept it in the folder (C:\Program Files\Oracle\Coherence for .NET\examples\ContactCache.Java\src\examples).
Thanks....

"Abstract" method in a non-abstract class

Hi all.
I have a class "SuperClass" from which other class are extended...
I'd like to "force" some methods (method1(), method2, ...) to be implemented in the inherited classes.
I know I can accomplish this just implementing the superclass method body in order to throw an exception when it's directly called:
void method1(){
throw new UnsupportedOperationException();
}...but I was wondering if there's another (better) way...
It's like I would like to declare some abstract methods in a non-abstract class...
Any ideas?

The superclass just models the information held by
the subclasses.
The information is taken from the database, by
accessing the proper table (one for each subclass).??
What do you mean by "models the information"?
You should use inheritance (of implementation) only when the class satisfies the following criteria:
1) "Is a special kind of," not "is a role played by a";
2) Never needs to transmute to be an object in some other class;
3) Extends rather than overrides or nullifies superclass;
4) Does not subclass what is merely a utility class (useful functionality you'd like to reuse); and
5) Within PD: expresses special kinds of roles, transactions, or things.
Why are you trying to force these mystery methodsfrom the superclass?
It's not mandatory for me to do it... I 'd see it
just like a further way to check that the subclasses
implements these methods, as they have to do.That's not a good idea. If the superclass has no relation to the database, it shouldn't contain methods (abstract or otherwise) related to database transactions.
The subclasses are the classes that handle db
transaction.
They are designed as a binding to a db table.And how is the superclass designed to handle db transactions? My guess (based on your description) is that it isn't. That should tell you right away that the subclasses should not extend your superclass.

Non-servlet class in servlet program

hi,
I declare a non-servlet class which is defined by myself in a servlet class. I passed the complie but got an runtime error said NoClassDefFoundError. Does anyone can help me? Thanks.
