Objects-by-value

Hi all,
I am using WLS 5.1/Visibroker 4.0 for C++ and I have the following
questions:
The RMI-IIOP example in WLS 5.1 worked, but it is not shown how objects
are passed over the wire. Is there example code which does more than say
"Hello World"?
How I can access an ejb from C++ by RMI-IIOP?
And how can I pass Objects-by-value?
What are the parameters I have the rmic-compiler to call with?
Any help will be greatly appreciated!

For the moment....
There are no additional examples. New examples will accompany the 5.1.1 release, due shortly. If anything useful becomes available before the end of the month, I will post it to this list.
Objects are marshaled per the spec, but there is the trouble: the spec requires that the transitive closure of the types for any given object be described in the idl for the value type. So, a simple object, 'public class Foo extends java.lang.Object {}', is straight forward in that you must
implement the one value type in C++, but an ejb home is another matter: the home drags in 100+ value types, which you must implement for the C++ compiler of your choice.
To access an ejb from C++ I recommend the following:
-- create a home such that it defines a finder that returns an instance of the bean's remote interface.
-- define the bean's remote interface such that useful methods use only primitive types, strings and remote interfaces.
-- generate the idl from ejbc/rmic... call either code generator with the -idl command parameter
-- remove all the value types (or carefully select the value types you will need) from the idl files corresponding to the home and remote interfaces.
-- generate the C++ code from the idl
The step where you trim away the value types is so that you can make the effort to link the C++ code manageable.
Hope this helps.

Eduardo -
Could you clarify -
When you state:
...define the bean's remote interface such that useful methods use only primitive types, strings and remote interfaces.
what do you mean by the last two words: "remote interfaces"? Do you mean "objects that implement the java.rmi.Remote interface"?

Hi,
Did you talk about the Microsoft Azure Active Directory Sync tool ?
If yes, this issue occurs if one or more of the following conditions are true:
An object in the on-premises Active Directory has an SMTP address that's the same as the SMTP address of the object that's reporting the problem.
An object in the on-premises Active Directory has a mail attribute that's identical to the object that's reporting the problem.
An object already exists in your organizational account and has the same SMTP address or mail attribute as the object in the on-premises Active Directory

Return Objects by Value/Reference?

Could someone please tell me which of this methods would be faster:
import java.util.ArrayList;
import java.util.List;
public class Test {
 public static final int MAX_ITER = 2000000;
 public static void main(String[] args) {
 long begin, end = 0;
 //Return Object by Value
 begin = System.currentTimeMillis();
 List list1 = returnByValue();
 end = System.currentTimeMillis();
 System.out.println(end - begin);
 //Return Object by reference
 begin = System.currentTimeMillis();
 List list2 = new ArrayList();
 returnByRef(list2);
 end = System.currentTimeMillis();
 System.out.println(end - begin);
 public static List returnByValue() {
 List list = new ArrayList();
 for(int i=0; i<MAX_ITER; i++)
 list.add(new Integer(i));
 return list;
 public static void returnByRef(List list) {
 for(int i=0; i<MAX_ITER; i++)
 list.add(new Integer(i));
}From what I understand, returnByValue would be slower as it involves creating a local List, and then returning it by way of copying itself? But surprisingly, both methods take almost identical times to run. Also, please run each method individually one at a time per run, otherwise for some reason, the second method always takes longer if ran simultaneously. Thanks.

Okay, I thought about that, too, because I thought

I don't care about my post count. Maybe next time

I think that telling people to believe the evidence in front of them is a good service to provide. You ran a test that told you the two were virtually identical. I gave you another viewpoint that said side effect free functions should be preferred, especially in situations like this one. No post count boosting there. That's good information.

How are objects and values passed in rmi?

how are objects and values passed in rmi?

In java there are two mwthods of passing aruguments and returning results.
1) by value
2) by reference.
While invoking local methods, java passes primitive types by value and objects by reference.
However while invoking remote methods both these data types are passed by value. Except for the objects being exported. Reason being two different JVM's are involved and thus memory addresses references of one are meaningles for the other. However "pass by value" for values of type object are implemented as deep copy.

How To Retrieve an Object's Value Defined Using c:set ... Tag?

I have the value of a variable defined in JSP#1 (JSP#1 is not a form) using JSTL tag:
<c:set var="id" value="${articleForm.article}" scope="session"/>Now, I have an object 'id' in the session scope. The object 'id' and all the information, which are defined in JSP#1, are forwarded to JSP#2.
JSP#2 is a form. But, the 'id' is not used in JSP#2.
JSP#2 has a submit button and then, a servlet takes over the control after that button is clicked. All the text fields in JSP#2 together with the object 'id' are forwarded to this servlet.
I have two questions:
1. I should put this object 'id' in a request scope or a session scope? Currently, it is in a session scope.
2. How to retrieve the value of this object 'id' in this servlet? (I do not want to print the value out. I want to retrieve the value and store it in a database.)
int articleID = Integer.parseInt( session.getAttribute( "id" ) ); or, it should be retrieved in another way?

I'm not sure you understand the concept of a session object.
Java objects stay on the server. There is no transmission between the web browser and the client.
The scope just sets how long the server "remembers" that variable.
request scope - only lasts one request. Once a web page is returned to the client, the server forgets all request variables.
session scope - lasts for one user - across multiple requests/web pages.
1. I should put this object 'id' in a request scope or a session scope? Currently, it is in a session scope.From your description, you appear to have it right - your object should be in session scope.
2. How to retrieve the value of this object 'id' in this servlet? (I do not want to print the value out. I want to retrieve the value and store it in a database.)If articleForm.article is an String then that looks the right way to access it.
You might have to do it like this:
int articleID = Integer.parseInt( (String)session.getAttribute("id"));
The Integer.parseInt method takes a String as a parameter - while session.getAttribute() returns an Object.
This code will work if the object stored in the session is a String.
The object stored in the session is ${articleForm.article} What type does articletForm.getArticle() return? That is the type you need to cast it to when retrieving it from the session.

How to have custom control in DataGridView display object's value?

I have a sample project located
here
The project has a main form `Form1` where the user can enter customers in a datagridview. The `CustomerType` column is a custom control and when the user clicks the button, a search form `Form2` pops up.
The search form is populated with a list of type `CustomerType`. The user can select a record by double-clicking on the row, and this object should be set in the custom control. The `DataGridView` should then display the `Description` property but in the background
each cell should hold the value (ie. the `CustomerType` instance).
The relevant code is located in the following classes:
The column class:
public class DataGridViewCustomerTypeColumn : DataGridViewColumn
public DataGridViewCustomerTypeColumn()
: base(new CustomerTypeCell())
public override DataGridViewCell CellTemplate
get { return base.CellTemplate; }
set
if (value != null && !value.GetType().IsAssignableFrom(typeof(CustomerTypeCell)))
throw new InvalidCastException("Should be CustomerTypeCell.");
base.CellTemplate = value;
The cell class:
public class CustomerTypeCell : DataGridViewTextBoxCell
public CustomerTypeCell()
: base()
public override void InitializeEditingControl(int rowIndex, object initialFormattedValue, DataGridViewCellStyle dataGridViewCellStyle)
base.InitializeEditingControl(rowIndex, initialFormattedValue, dataGridViewCellStyle);
CustomerTypeSearch ctl = DataGridView.EditingControl as CustomerTypeSearch;
if (this.Value == null)
ctl.Value = (CustomerType)this.DefaultNewRowValue;
else
ctl.Value = (CustomerType)this.Value;
public override Type EditType
get { return typeof(CustomerTypeSearch); }
public override Type ValueType
get { return typeof(CustomerType); }
public override object DefaultNewRowValue
get { return null; }
And the custom control:
public partial class CustomerTypeSearch : UserControl, IDataGridViewEditingControl
private DataGridView dataGridView;
private int rowIndex;
private bool valueChanged = false;
private CustomerType value;
public CustomerTypeSearch()
InitializeComponent();
public CustomerType Value
get { return this.value; }
set
this.value = value;
if (value != null)
textBoxSearch.Text = value.Description;
else
textBoxSearch.Clear();
private void buttonSearch_Click(object sender, EventArgs e)
Form2 f = new Form2();
DialogResult dr = f.ShowDialog(this);
if (dr == DialogResult.OK)
Value = f.SelectedValue;
#region IDataGridViewEditingControl implementation
public object EditingControlFormattedValue
get
if (this.value != null)
return this.value.Description;
else
return null;
set
if (this.value != null)
this.value.Description = (string)value;
public object GetEditingControlFormattedValue(DataGridViewDataErrorContexts context)
return EditingControlFormattedValue;
public void ApplyCellStyleToEditingControl(DataGridViewCellStyle dataGridViewCellStyle)
this.BorderStyle = BorderStyle.None;
this.Font = dataGridViewCellStyle.Font;
public int EditingControlRowIndex
get { return rowIndex; }
set { rowIndex = value; }
public bool EditingControlWantsInputKey(Keys key, bool dataGridViewWantsInputKey)
return false;
public void PrepareEditingControlForEdit(bool selectAll)
//No preparation needs to be done
public bool RepositionEditingControlOnValueChange
get { return false; }
public DataGridView EditingControlDataGridView
get { return dataGridView; }
set { dataGridView = value; }
public bool EditingControlValueChanged
get { return valueChanged; }
set { valueChanged = value; }
public Cursor EditingPanelCursor
get { return base.Cursor; }
#endregion
private void CustomerTypeSearch_Resize(object sender, EventArgs e)
buttonSearch.Left = this.Width - buttonSearch.Width;
textBoxSearch.Width = buttonSearch.Left;
However, the `DataGridView` is not displaying the text and it also is not keeping the `CustomerType` value for each cell.
What am I missing?
Marketplace: [url=http://tinyurl.com/75gc58b]Itza[/url] - Review: [url=http://tinyurl.com/ctdz422]Itza Update[/url]

Hello,
1. To display the text, we need to override the ToString method for CustomerType
public class CustomerType
public int Id { get; set; }
public string Description { get; set; }
public CustomerType(int id, string description)
this.Id = id;
this.Description = description;
public override string ToString()
return this.Description.ToString();
2. To get the cell's value changed, we could pass the cell instance to that editing control and get its value changed with the following way.
public partial class CustomerTypeSearch : UserControl, IDataGridViewEditingControl
private DataGridView dataGridView;
private int rowIndex;
private bool valueChanged = false;
private CustomerTypeCell currentCell = null;
public CustomerTypeCell OwnerCell
get { return currentCell; }
set
currentCell = null;
currentCell = value;
public CustomerTypeSearch()
InitializeComponent();
private void buttonSearch_Click(object sender, EventArgs e)
Form2 f = new Form2();
DialogResult dr = f.ShowDialog(this);
if (dr == DialogResult.OK)
currentCell.Value = f.SelectedValue;
this.textBoxSearch.Text = f.SelectedValue.Description;
#region IDataGridViewEditingControl implementation
public object EditingControlFormattedValue
get
if (this.currentCell.Value != null)
return (this.currentCell.Value as CustomerType).Description;
else
return null;
set
if (this.currentCell != null)
(this.currentCell.Value as CustomerType).Description = (string)value;
public object GetEditingControlFormattedValue(DataGridViewDataErrorContexts context)
return EditingControlFormattedValue;
public void ApplyCellStyleToEditingControl(DataGridViewCellStyle dataGridViewCellStyle)
this.BorderStyle = BorderStyle.None;
this.Font = dataGridViewCellStyle.Font;
public int EditingControlRowIndex
get { return rowIndex; }
set { rowIndex = value; }
public bool EditingControlWantsInputKey(Keys key, bool dataGridViewWantsInputKey)
return false;
public void PrepareEditingControlForEdit(bool selectAll)
//No preparation needs to be done
public bool RepositionEditingControlOnValueChange
get { return false; }
public DataGridView EditingControlDataGridView
get { return dataGridView; }
set { dataGridView = value; }
public bool EditingControlValueChanged
get { return valueChanged; }
set { valueChanged = value; }
public Cursor EditingPanelCursor
get { return base.Cursor; }
#endregion
private void CustomerTypeSearch_Resize(object sender, EventArgs e)
buttonSearch.Left = this.Width - buttonSearch.Width;
textBoxSearch.Width = buttonSearch.Left;
Cell:
public class CustomerTypeCell : DataGridViewTextBoxCell
public CustomerTypeCell()
: base()
public override void InitializeEditingControl(int rowIndex, object initialFormattedValue, DataGridViewCellStyle dataGridViewCellStyle)
base.InitializeEditingControl(rowIndex, initialFormattedValue, dataGridViewCellStyle);
CustomerTypeSearch ctl = DataGridView.EditingControl as CustomerTypeSearch;
ctl.OwnerCell = this;
public override Type EditType

Unable assign a BPM Object field value to a JSP Variable using "invoke"

Hi,
I'm unable to retrieve a value returned by a BPM Object Method and use it in JSP. Here is what I'm trying to achieve:
BPM object named : "myObject" has a method "getRequiredValue" which returns a "String". I want to assign the value returned by "getRequiredValue" to a JSP Variable "myVariable" using invoke method as below:
<% String myVariable = ""; %>
<f:invoke var="${myObject}" methodName="getRequiredValue" retAttName="myVariable"/>
<% out.println ("myVariable: " + myVariable); %>
When I execute the above code I don't get the value being returned by "getRequiredValue" into "myVariable".
Any help would be highly appreciated!
regards,
MK

1. Make sure you mark the "Server Side Method" property of the getRequiredValue method to "Yes".
2. I guess you dont need to specify "<% String myVariable = ""; %>". Try removing it.
3. Replace "<% out.println ("myVariable: " + myVariable); %>" by <c:out value="${myVariable}"/> just in case!
4. Lastly, I hope "myObject" is the name of the instance variable in your screenflow, and not the BPM object name.
Hope this helps

Can I print an objects fields' values in a loop without having to cast?

Hi,
I have a Class with about 30 (public)fields and I need to print the values of each of them to a file. I tried the getFields() method of the Class object, but couldn't get the desired result, especially that the documentation says no order is guaranteed when using this method and I need to know have one in order to be able to read from the file when reconstriucting the object.
I considered using the Object Streams but I need it to be in human readable format, preferably ASCII, as the fields are int, long, String, Date...
Also the object might grow so I don't want to hardcode the writing and reading methods, would like it to be as generic as possible.
Thanks for help

hallo,
have you tried XMLEncoder ; something like this (from the API docs):
XMLEncoder e = new XMLEncoder(
new BufferedOutputStream(
new FileOutputStream("Test.xml")));
e.writeObject(new JButton("Hello, world"));
e.close();
you can customize which parts of the objects are written, i think. otherwise, just create bean-like setter and getter methods for the fields and they should be automatically written (and read with XMLDecoder).
ciao, -sciss-

Problem changing Long object's value

Hi,
I want to know what is the way to change the value of a Long object (if any).
I didn't find set for this, and i want to change the value after creating the object withoud changing the reference (not by longObject = new Long(5)).
Thanks,
Snayit

That's not possible. Long is immutable (as are String, and all other primitive wrapper classes). This is done because immutable objects have huge advantages in many cases (like when acting as the key to a hashmap).

Binding an object tag value / Creating HTML via a backing bean

I have a task flow that sets some properties in my backbean. I've bound the "classid" of an <object> tag to one of these values. However, the first time i load the JSFF page, the object tag isnt created, but if i refresh the page, its loaded correctly.
This would lead me to believe that the binding isn't being done before the JSFF is rendered, so the question is. Does anyone know how to fix this? and if not, i have thought about creating a backing bean that would add the <object> tag to the page with the bind value, but have no idea how i would go about this.
Does anyone know of any good tutorials on adding HTML via a backing bean before the page is rendered?

After further investigation and talking to a colleague, It seems it might not be binding related, since if I print out the bind in a text field, it displays correctly. I think the problem is because I am trying to inject an object tag (hosts a .NET control) into a fragment, but this is never picked up and rendered. Thus, when I do a full page refresh, the object tag is added and all goes well.
If I attempt to bind/add a ADF Faces component this way, it works correctly.
Do you know how to inject code for a fragment?, I am very stuck at the moment - don't have that much knowledge on ADF, so any links/help would be appreciated.
My scenario is this:
I am using a task flow that has 2 fragments.
Fragment 1: set properties - has two input fields and a next button which are bound to a bean that saves the input fields
Fragment 2: display object tag using step ones properties.

Yes, the interfaces of those tools are often a hazard in themselves...
I typically recommend customers to delete them completely. Sometimes this comment also exists in the code itself, but who reads code now-a-days in GRC projects, and why should they have to? ;-(
This looks very much like one of those tools (where the SQL statements are built externally).

Mapping an object using values from multiple tables

Is it possible to use values looked up in other tables when mapping an object?
For example: I have three tables. In table 1, I have fields for 'cityCode' and 'stateCode'. Table 2 is a state table which contains a list of stateCodes and corresponding stateIds. Table 3 is a city table with cityCodes listed by stateId (the city code is unique within the stateId but can be duplicated under other stateIds). Table 3 also contains the cityName for the matching cityCode/stateId pair.
I am ultimately trying to match a cityName to a cityCode. I can't figure out how to tell toplink use the stateId returned when mapping Table 1 to Table 2 via stateCode when mapping cityCode in Table 1 to Table 3.
Any help is greatly appreciated
--matt

What does your object model look like, do you have a single object with data from all three tables in it?

In general because the cardinality of the tables and usage does not match, I would not recommend using multiple tables to map this. Instead define a CityNameManager class that preloads and stores all of the city names for each state, (possible lazy initializing each set of cities per state). Your getCityName() method in your class would then just use this manager.

You could map the multiple tables but it may be difficult, and would most likely need to be read-only because I don't think you want to insert into the table2 or 3. You basically have a foreign key table1.stateCode => table2.stateCode, (table1.cityCode, table2.stateId) => (table3.cityCode, table3.stateId). You probably cannot define this in the Mapping Workbench, so would need to use the ClassDescriptor code API and an amendment method. If you can't get the foreign keys to work you can always use the descriptor multipleTableJoinExpression and define the join directly.

You could also define a OneToOneMapping to the CityName from your object using the cityCode and using a selectionCriteria() on your mapping to provide an expression that uses the getTable() method to join to the intermediate table.
