Logger is the name of the newer class which replaced Category. The issue is
the same for both of them, however.
At some point in your application, the server needs to return data back to
the client (typically in J2EE apps this is accomplished with ValueObjects or
DataTransferObjects depending on your preferred patterns catalog). That
server return will be serialized for transport back to the client (actually
for transport back to the client stub, which then deserializes it for the
calling client).
So in your set up, I am guessing that ValueObjectFactory is returning a
collection of a class named like EmployeeVO. If this collection is then
sent back to the client and the EmployeeVO instances making up the elements
of that collection define a Logger (or Category) instance, the serialization
will fail because Logger/Category is not serializable. You would need to
mark the Logger/Category variable on the EmployeeVO class as transient.
So if you have:
public class EmployeeVO
{
private Category log = Category.getInstance( getClass() );
...
}
change to:
public class EmployeeVO
{
private transient Category log = Category.getInstance( getClass() );
...
}

|
|Well. I am not sure about Looger variable. I am using
|
|private Category log = Category.getInstance(getClass());
|
|statement in the OrganizationManager session bean. Log4j
|initialization is done successfully in the view controller
|servlet. This error occurs when the
|findColOfEmployeeVOByLoginInfo method of the
|OrganizationManager session bean is called.
|
|**** method ***
| public Collection findColOfEmployeeVOByLoginInfo(String
|username, String password) throws SessionException,
|RemoteException {
| try {
| EmployeeHome home = (EmployeeHome)
|
|ServiceLocatorBean.getInstance().getLocalHome(
| "ejb/Employee",
|EmployeeHome.class);
|
| return
|ValueObjectFactory.getInstance().getCollectionOfVO(
|
|home.findByLoginInfo(username, password));
| } catch (Exception re) {
| throw new
|SessionException(this.getClass().getName()+".findByLoginInf
|o():"+re.getMessage());
| }
| }
|***
|The method getCollectionOfVO gets the EJB interface
|objects and then copies values into JavaBean objects and
|returns a collection of JavaBean objects. Both EJB and
|JavaBean have
|
|- private Category log = Category.getInstance(getClass());
|
|defined in them. But the variable "log" is not copied.

|
|It looks like maybe you are trying to define a Logger as a
|variable on
|something which is getting serialized. Logger does not
|implement the
|Serializable interface. You must mark that Logger
|variable as transient, or
|explicitly read and write it yourself during serialization.
