Mapping an attribute to different classes

I have a class, A that contains an attribute called "state" of type State. Class State is an abstract class that contains 2 methods. Classes ActiveState and CompletedState extend State and none of them have attributes. They only implement the 2 methods. I am having problems trying to map the state attribute of A since the state can be either an ActiveState or a CompletedState. Any suggestions?

Hi Cynthia,
I would assume that the State object itself is un-persistentable as there is in fact no persistent attribute defined in either State or it's subclasses.
If you treat the State as a kind of status flag to A class, you could use Transformation Mapping for the attribute (refer to the manual for the setting of the mapping).
If you do have persistent attributes in State and/or it's subclasses, you could simply use 1:1 mapping from A to State, and use TopLink inheritance support to map State, ActiveState and CompletedState.

Same parameter-map used on 2 different classes

Greetings,
If the same parameter-map (type connection or http) is used on two different policy-map classes, will that create a conflict in how traffic for each of serverfarms uses persistence or inactivity timeout (script 1)?

Unable to map/get Attributes with import of LDIF Object Class

Hi All,
We are trying to take import of Customized Object Class and Attributes into OID through LDIF.
LDIF import command is:
./ldapadd -p 3060 -h myhost -D "cn=orcladmin" -w Ac123456 -f xyzObjClass.ldif
LDIF contents are:
dn: cn=subSchemaSubentry
changetype: modify
add: objectclasses
objectclasses: ( 1.3.6.1.4.1.1436.2.46 NAME 'ProviderObjClass' SUP ( organizationalPerson $ person $ top ) STRUCTURAL MAY ( attr1 $ attr2 ) )
Note: attr1 and attr2 are already imported into OID.
Result: We are able to create Object Class and also able to inherit Super Class. But we are not able to map the attributes to our Object Class.
Can anybody help me in importing ?
Thanks & Regards,
Newbie

Again, I don't work with Java and you should ask Java-related question in Flex (or Java) forum.
Java or not - you need to package your server side language specific object into something that AS understands (text, XML, AMF object) and load this data into AS via, perhaps, URLLoader. Or you can open socket. Then you parse this data with AS3 code in SWF.

Mapping UME attribute problem

Hi all,
I'm using EP SP16 with a MSADS flat hierarchy datasource.
I've mapped the attribute "pwdLastSet" in the configuration file but when I list the "attributeNames" of my user, it doesn't exist.
This mapping is no different than previous mapping I've mapped such as extensionAttribute, company, dn and others all done successfully.
Can't "pwdLastSet" be mapped?
Amit

hie could u please paste the xml configuration file here. Also the attribute pwdLastSet is a read only attribute from ADS.

Is there a way to not have to map all attributes

Is there a way to have a attribute in a class not have to be mapped to a
db column? I have a base class that has a property that is used for
convience but doesn't map to any DB column. I am currently getting a No
mapping information was found error.
Thanks
Jeff

Jeff,
That's the right answer, assuming that you may want that field to be in a
serialized object of that class. If you don't want the field serialized,
then making the field transient will cause Kodo to use
persistence-modifier="none" by default.
Thanks,

I think I found my own answer.
in the metadata file add the column and set thepersistence-modifier="none"
like below.
<class >
<field name="sessionName" persistence-modifier="none"/>
</class>

Mapping private attribute in workbench

Hi,
The mappingworkbench will not generate a toplink-deployment-descriptor.xml for directly mapped attributes that have accessibility private. Other comments in this forum and weblinks that date from Webgain-Toplink describe that this should be possible.
So my questions are:
- where can I find current toplink documentation that describes how to map private attributes?
- how can I get around the fact that the mapping workbench does not accept methods with private accessibility?
Thanks for your insights,
Joost de Vries
Nederland

Hi Donald,
First; what I want to do is create a 'value object' [cf. Fowler], that is: a java object that can be given values for its attributes at creation time, but not afterwards.
So the way I try to accomplish that is by making the mutator (set-method) private.
This is how to recreate the situation: I have a working mapping. I change the set method of an attribute to private. I restart jDeveloper (*), I generate the toplink-deployment-descriptor.xml. The generation fails with the message 'Method setDjiNummer(Integer i) has private access in class org.myOrg.MyClass'.
Sincerely,
Joost de Vries
Nederland
(*) by the way: is there a better way to make sure the Toplink Workbench sees changes made to java classes?

Mapping object attributes to ArrayField widget

Is there a way to specify get/set methods for fields within an
ArrayField widget instead of public attributes of the mapped type?
We are trying to enforce strict encapsulation of our data objects, but
it seems that the only way to display our data objects in an ArrayField
widget is to bind each field in the ArrayField to a PUBLIC attribute of
our object. I was hopeful that the virtual attribute would take care of
this but apparently, the virtual attributes can only access public
attributes on our class.
An obvious solution to this is to retrieve the private attributes of our
objects via their Get methods and then manually adding them to the
ArrayField widget, but this seems to be a lot of wasted processing.
Any thought would be greatly appreciated. Send replies directly to me at
[email protected]
Thanks,
Van

Hi,
Refer your suggestion
Confirm that
4. The datatype for the field is same as the data type of the vo attribute.
This is what I need to Solve.The datatypes are not similar
I want to show Students Number in the table column
DataType for the field in the Table is selected as "Number"
In the View Object there is no datatype called "Number".So, I selcted "Integer".
Now, how can I show VO attribute of type "Integer" in a table column of type "Number"..
thanks,

Problems to map organization attribute from IDM 7 to my own Resource

Hi
I have a problem mapping the organization user attribute to my resource. My Resource xml looks like:
          " <AccountAttributeTypes>\n"+
          " <AccountAttributeType name='accountId' mapName='loginName' mapType='string'/>\n"+
          " <AccountAttributeType name='email' mapName='email' mapType='string'/>\n"+
          " <AccountAttributeType name='firstname' mapName='firstname' mapType='string'/>\n"+

          " <AccountAttributeType name='organization' mapName='organization' mapType='string'/>\n"+
          " </AccountAttributeTypes>\n"+
but when I try to get the organization attribute in my resource it comes null. I get it like follows:
     WSAttributes attributes = user.getWSAttributes();
     attributes.getValueAsString("organization")
Does anyone know how to map organization attribute to a Resource?
Thanks.

I can pass the Organization attribute to my Resource configuring this in MetaView tab.. But only pass me this attribute when I update an account.
in my resource xml is:
static String gfResourceXml =
          "<Resource name='ResourceAdapter' class='com.qoslabs.jes.idm.ResourceAdapter' typeString='ResourceAdapter' typeDisplayString='ResourceAdapter'>\n"+

Two equal objects, but different classes?

When programming on binding Referenceable object with JDK version 1.5.0_06, I have encountered a very strange phenomenon: two objects are equal, but they belong to different classes!!!
The source codes of the program bind_ref.java are listed as below:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++
import java.lang.*;
import java.io.*;
import java.util.*;
import javax.naming.*;
import javax.naming.spi.ObjectFactory;
import java.util.Hashtable;
public class bind_ref {
public static void main( String[] args ) {
// Set up environment for creating the initial context
Hashtable env = new Hashtable();
env.put( Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.RefFSContextFactory" );
env.put( Context.PROVIDER_URL, "file:/daniel/" );
Context ctx = null;
File f = null;
Fruit fruit1 = null, fruit2 = null;
byte [] b = new byte[10];
try {
ctx = new InitialContext( env );
Hashtable the_env = ctx.getEnvironment();
Object [] keys = the_env.keySet().toArray();
int key_sz = keys.length;
fruit1 = new Fruit( "Orange" );
     SubReference ref1 = fruit1.getReference();
ctx.rebind( "reference", fruit1 );
     fruit2 = ( Fruit )ctx.lookup( "reference" );
     System.out.println( "ref1's class = (" + ref1.getClass().toString() + ")" );
     System.out.println( "fruit2.myRef's class = (" + fruit2.myRef.getClass().toString() + ")" );
     System.out.println( "( ref1 instanceof SubReference ) = " + ( ref1 instanceof SubReference ) );
     System.out.println( "( fruit2.myRef instanceof SubReference ) = " + ( fruit2.myRef instanceof SubReference ) );
     System.out.println( "ref1.hashCode = " + ref1.hashCode() + ", fruit2.myRef.hashCode = " + fruit2.myRef.hashCode() );
     System.out.println( "ref1.equals( fruit2.myRef ) = " + ref1.equals( fruit2.myRef ) );
} catch( Exception ne ) {
System.err.println( "Exception: " + ne.toString() );
System.exit( -1 );
+++++++++++++++++++++++++++++++++++++++++++++++++++++++
All the outputs are shown as below:
=======================================================

ref1.hashCode = -1759114666, fruit2.myRef.hashCode = -1759114666
ref1.equals( fruit2.myRef ) = true
========================================================
I hightlight the critical codes and outputs related to the strangeness with bold texts.
Who can tell me what happens? Is it really possible that two objects belonging to different classes are equal? If so, why that?

It can also depend on how you implement the equals method.
class Cat {
    String name;
    Cat(String n) {
        name = n;
class Dog {
    String name;
    Dog(String n) {
        name = n;
    public boolean equals(Object o) {
        return name.equals(o.name);
    public static void main(String[] args) {
        Dog d = new Dog("Fred");
        Cat c = new Cat("Fred");
        System.out.println(d.equals(c));
}

Can't call or execute of different class files in a main program

Hi, I got a main program which can call 3 different classes. The main program have an implicit-choice List as a starting menu. If one of the file is selected, the files will call out and display it. However, i managed to call the 1st 2 files, and the 3rd files can't display anything after selected.
I enclosed my code as below:

May i know what is problem am i facing now? And how to solve it.
Thanks.

Thanks to all for your thoughts and replies. I liked the xargs suggestion, so I tried that first. I would have (may still) try the stdin suggestion, followed by writing the grep output to a file.
xargs does work, in a way I didn't expect it to, but that could be due to my inexperience with the workings of the shell.
here's a line from my test script
cat file | grep foo | xargs java com.company.test.TEchoArghere's the contents of 'file'
123foo
abc
qafoozv
qaz
wsx
qwefoort
zxcfooh
sdfghhere's the output from the test class, which just echos any arguments
::number of args: 4
::args[0] 123foo
::args[1] qafoozv
::args[2] qwefoort
::args[3] zxcfoohso xargs appends all the values from grep into an argument list and call the java class once.
when I took xargs out of the script, nothing was passed to the class:
::number of args: 0this was really interesting and something to keep in my back pocket for future use.
Thanks again to all.

Page Attributes and Application Class Attributes

Hi, everyone,
I am quite new to BSP.
I have a question here:
what is the difference between page attributes and application class attributes of a bsp application? As they are both global attributes, there seems to be no big difference when we use them.
thanks a lot.
Fan

Hi Fan,
a BSP application can be made up of many pages.
A page attribute is visible only in the page it is associated with.
Attributes of the application class are visible from every page in that application.
Cheers

How to define a Value for an Attribute of an Class

Hi,
How to define a Value for an Attribute of a Class ...
( I need to change the value of an Attribute of a class in standard program ....
Ex...
   cl_hrce_masterswitches=>infotype_framework_is_active
Here infotype_framework_is_active is the attribute .. its value in standard program is 'X'... Now i need to change it as ' '.
How to define it and set value as ' '.

Hello Surendar
The static attribute INFOTYPE_FRAMEWORK_IS_ACTIVE is read-only and there is not SETTER method to manipulate its value.
However, the attribute is filled in the CLASS_CONSTRUCTOR:
METHOD class_constructor.
    IF ce_is_active                 = true OR
       global_payroll_is_active     = true OR
       mngmt_global_empls_is_active = true.
      infotype_framework_is_active = true.
      perid_infotype_is_active     = true.
    ELSE.
      infotype_framework_is_active = false.
      perid_infotype_is_active     = false.
    ENDIF.
ENDMETHOD.
Thus, you need to analyze how attribute CE_IS_ACTIVE, GLOBAL_PAYROLL_IS_ACTIVE and MNGMT_GLOBAL_EMPLS_IS_ACTIVE are filled in the CLASS_CONSTRUCTOR.
For sure you will find customizing settings that are responsible for this.
Regards
Uwe
