How to pass a "user defined" object to a thread?

Hi...
I have created an object say 'obj1' . I want to pass to a thread say 'T1' .
The thread T1 implements the runnable class.
I need to pass the "obj1" object to the T1 for it to be processed in the "run" method of T1.
As far as I have seen there is no thread constructor in Java that accepts an object created by the user.
My question is there any way to pass an object to a thread? and if so how can it be done?

You can just add your own method to the class. Then call that method to pass the object to the thread before you call start on the thread.
class MyThread implements Runnable
   public void run()
      userObj.whatever();
   public void addObj(Object obj)
      userObj = obj;
   Object userObj = null;
// your code
MyThread thread = new MyThread();
thread.addObj(myObj);
thread.start();As long as you don't call start before your pass the object to your thread, then you won't have a problem. Hope this helps.

  • How to pass a user defined table type to stored procedure?

    Hi,
    I am trying to call a stored procedure from Java. The store procedure has three IN parameter, 2 IN/OUT params and 3 OUT parameters. The two IN/OUT parameters are user defined objects. Can anyone tell me how to set these IN/OUT parameters in Java.
    Thanks

    It is database/driver specific so you need to use the specific functionality of the driver (not jdbc) to access it.

  • How can i send user defined Object as a argument to the MBean methods in authentication provider to create user?

    I developed our own Authentication, Identity Assertion & Authorization providers

    user defined object as a argument and returns a user defined object. i am able
    to call all the methods which takes java objects(for example: String, int, ArrayList,

    any user defined object then it gives exception. if in the argument i used user

    Is there any way to use user defined object as an argument to MBean method?
    can anyone please help us as we r in the final stage of the project?

  • How to clone a user-defined object?

    Hello,
    I need to clone an Object[] array (propArray) that holds objects of Integer, Double, Boolean type, along with objects of user-defined ClassA, ClassB, ClassC type. The matter is that the ClassA object isn't being cloned, while the rest of the user-defined objects are cloned just fine.
    In more detail, ClassA has two properties:
    public class ClassA implements Cloneable{
       private String penaltyFor;
       private Penalty[] penaltyArray;
       protected Object clone(){
          try{
             ClassA o = (ClassA)super.clone();
             o.penaltyFor = this.penaltyFor;
    //         o.penaltyArray = (Penalty[])penaltyArray.clone();  //This ain't working.
             //But neither does this :(.
             int penCount = this.penaltyArray.length;
             o.penaltyArray = new Penalty[penCount];
             for(int i = 0; i < penCount; i++)
                o.penaltyArray[i] = (Penalty)this.penaltyArray.clone();
    return o;
    } catch(CloneNotSupportedException e){ throw new InternalError(); }
    The Penalty class contains properties of primitive type and here is its clone() method:
    public class Penalty implements Cloneable{
       private String penaltyDesc;
       private int lowLimit, upperLimit, penaltyValue;
       protected Object clone(){
          try{
             Penalty o = (Penalty)super.clone();
             o.penaltyDesc = this.penaltyDesc;
             o.lowLimit = this.lowLimit;
             o.upperLimit = this.upperLimit;
             o.penaltyValue = this.penaltyValue;
             return o;
          } catch(CloneNotSupportedException e){ throw new InternalError(); }
       }I don't know what else to try. I suppose the problem is the Penalty[] array, but I may be wrong. An alternative would be to use Copy Constructors, but it will cause too many changes to the code, since the clone() method is used for the propArray copy in many places and the ClassA object is a late addition to the propArray (unfortunately it wasn't planned to exist from the beginning).
    Thank's.

    class ClassA implements Cloneable{
       private String penaltyFor;
       private Penalty[] penaltyArray;
       public Object clone(){
          try{
             ClassA o = (ClassA) super.clone();
             if (penaltyArray!=null){
                o.penaltyArray = (Penalty[]) penaltyArray.clone();
                for(int i = 0; i < penaltyArray.length; i++) {
                    Penalty penalty = this.penaltyArray;
    if (penalty!=null)
    o.penaltyArray[i] = (Penalty) penalty.clone();
    return o;
    } catch(CloneNotSupportedException e){
    throw new InternalError();
    class Penalty implements Cloneable{
    private String penaltyDesc;
    private int lowLimit, upperLimit, penaltyValue;
    public Object clone(){
    try{
    return super.clone();
    } catch(CloneNotSupportedException e){
    throw new InternalError();
    If your Penalties are immutable, you don't need to clone them -- rather,
    make then unclonable, like Strings.

  • Issue in passing Oracle User Defined Types to PL SQL from Websphere Applica

    HI,
    I am facing an issue when trying to pass Oracle collection object(User Defined Types) from Java to PL SQL. The issue happens inside J2EE application which is running inside Websphere Application Server 6.x. My database is Oracle 10g and i am using ojdbc1.4.jar as thin driver.
    The issue is that when i pass the Oracle Object from java side, the attribute values of the collection objects at the Oracle PL SQL side is coming as empty. I have tried the same java code in a standalone application and it works fine. The issue happens only when the application is running inside WAS.
    Anybody has any idea how to pass Oracle User Defined Types from WAS 6.x server to Oracle PL SQL?

    Andy Bowes wrote:
    Hi
    I am using WebLogic 8.14 & Oracle 9i with thin JDBC driver.
    Our application needs to perform the same DB operation for every item in a Java Collection. I cannot acheive the required performance using the standard Prepare & Execute loop and so I am looking to push the whole collection to Oracle in a single invocation of a Stored Procedure and then loop on the database.
    Summary of Approach:
    In the Oracle database, we have defined a Object Type :
    CREATE OR REPLACE
    TYPE MYTYPE AS OBJECT
    TxnId VARCHAR2(40),
    Target VARCHAR2(20),
    Source VARCHAR2(20),
    Param1 VARCHAR2(2048),
    Param2 VARCHAR2(2048),
    Param3 VARCHAR2(2048),
    Param4 VARCHAR2(2048),
    Param5 VARCHAR2(2048),
    and we have defined a collection of these as:
    CREATE OR REPLACE
    TYPE MYTYPE_COLLECTION AS VARRAY (100) OF MYTYPE
    There is a stored procedure which takes one of these collections as an input parameter and I need to invoke these from within my code.
    I am having major problems when I attempt to get the ArrayDescriptor etc to allow me to create an Array to pass to the stored procedure. I think this is because the underlying Oracle connection is wrapped by WebLogic.
    Has anyone managed to pass an array to an Oracle Stored procedure on a pooled DB connection?
    Thanks
    AndyHi. Here's what I suggest: First please get the JDBC you want to work in a
    small standalone program that uses the Oracle thin driver directly. Once
    that works, show me the JDBC code, and I will see what translation if
    any is needed to make it work with WLS. Will your code be running in
    WebLogic, or in an external client talking to WebLogic?
    Also, have you tried the executeBatch() methods to see if you can
    get the performance you want via batches?

  • UDO--user defined object

    how to use UDO--user defined object in sap b1????

    Creating UDO in SAP B1
    1. Create UDT, ( Create UDT as Document if want the code to be in auto increament form)
    2. Create UDFs for created UDT,
    3. Register Object using  "Object Registration Wizard",
                    (a) Put UDT's unique name in "UNIQUE ID" field of UDO (Image - UDO01.jpg) ,
                    (b) Do further as per requirements,
    4. After Registering the UDO, you can access it from where you have set it to access (@ UI Settings of "User - Defined Object Registration Wizard"),
    5. If you wana change the field location / change the design of the form, Open screen painter as and click on "Open User Defined Object List " (Mostly 3rd icon from Left in screen painter),
    6. Make required changes and save it by clicking "Save Form To Database" ( Mostly 2nd icon from Left in Screen Painter),
    7. Now the UDO is ready and can be used by user.

  • How can I use User-Defined Aggregate Functions in Timesten 11? such as ODCI

    Hi
    we are using Timesten 11 version and as per the documentation, it doesn't support User-Defined Aggregate Functions.
    So we are looking for alternatives to do it. Could you please provide your expert voice on this.
    Thanks a lot.
    As the following:
    create or replace type strcat_type as object (
    cat_string varchar2(32767),
    static function ODCIAggregateInitialize(cs_ctx In Out strcat_type) return number,
    member function ODCIAggregateIterate(self In Out strcat_type,value in varchar2) return number,
    member function ODCIAggregateMerge(self In Out strcat_type,ctx2 In Out strcat_type) return number,
    member function ODCIAggregateTerminate(self In Out strcat_type,returnValue Out varchar2,flags in number) return
    number
    How can I use User-Defined Aggregate Functions in Timesten 11? such as ODCIAggregateInitialize ?

    Dear user6258915,
    You absolutely right, TimesTen doesnt support object types (http://docs.oracle.com/cd/E13085_01/doc/timesten.1121/e13076/plsqldiffs.htm) and User-Defined Aggregate Functions.
    Is it crucial for your application? Could you rewrite this functionality by using standart SQL or PL/SQL?
    Best regards,

  • Wanting to copy DOM element child value into user defined object in PL/SQL.

    We have a DOM object and can retrieve the object elements. We are wanting to take the elements and map them to user defined object attributes. We want to then place the element child (the text portion of <item>Foo</item> into the object attribute. Is there a package or utility that is available where we can simply pass the DOM and user defined objects and "magic happens here"?

  • Link button to User Defined Object in Grid

    Hi,
    I'm using SAP B1 8.81 with B1DE.
    I have added a grid which is populated from a DataTable to a form.
    One of the columns in the grid contains the DocEntry of a User Defined Object.
    How can I display a link button on the grid ?
    Regards,

    Hello Ben,
    You need to set the column object type.

    Dim oEditCol As SAPbouiCOM.EditTextColumn = oGrid.Columns.Item("DocEntry")
    oEditCol.LinkedObjectType = "2" 'The SDK documentation says you should use the value 0, but in previous versions it didn't work, so I recommend you user a value other than -1 or 0
    You then need to catch the et_MATRIX_LINK_PRESSED event and other your user form...

  • Dispose a user-defined object in Java

    Hello,
    Suppose I have the following loop :
    while ( some_condition) {
    UserDefinedClass abc = new UserDefinedClass();
    // do some work and exit loop.
    Everytime, I enter this loop I instantiate a new object "abc". I am worrying that if I keep doing this, after a while, I will run out
    of memory. Is there a way to dispose a user-defined object? Or is this scenario taken care of by Java garbage collection process?
    Any advice is much appreciated.

    Hello,
    Thank you for your reply.
    I wonder if you could tell me how often Java does its garbage collection?That's pretty unpredictable.
    I ran a test and observed that
    my program's memory usage kept going up and up.If you gave it it 64M, and the most it ever needs at one time is 10M, it can still ramp up to the full 64M, even if it's doing frequent GC. Running GC does NOT mean that the JVM gives the memory back to the OS. It can do that, and I think it does under some circumstances, but there's no guarantee if, when, or how much it will give back. GC only means that the JVM has reclaimed space that is no longer in use by objects. Whether it holds onto that memory for future use or gives it back to the OS is up to it.

  • Object to user defined object

    I pushed user defined objects in to the Vector or Stack.
    But they return an java defined Object type when I try to use them.
    Is there way that I can convert this Object into my defined object.
    MyClass a;
    MyClass b;
    Stack table = new Stack();
    table.push(a);
    table.push(b);
    //now when i use pop to get it back it returns an Object type
    Object temp = table.pop();
    //how do I change this object into MyClass so i can have access to MyClass stuff?

    dam..thank you so much I feel stupid..Don't.
    Casting is one of those things that can take a while to get used to.
    In your original post, you asked: how do I change this object into MyClass so i can have access to MyClass stuff?
    It's important that you understand that casting doesn't change the object in any way.
    All it does is cause a reference that's been declared as one type to be treated as a different type. So even though all the compiler knows about what's returned from pop() is that it refers to an Object, you're telling it you know better, and that the object pointed at will in fact be a MyClass, and so you can access MyClass' members.
    If, at runtime, the object you happen to pop off the stack isn't a MyClass, casting won't magically turn it into one. You'll get a ClassCastException.

  • Portal Entitlements for user defined objects

    Hi,
    The UUP aggregates the user profile information from different backed data sources.
    One of the properties in the propertyset is a multivalued property. I populate

    PropertyMapKey propertyMapKeyM = new PropertyMapKeyImpl(null,"DA_Privilege");
