How to create jdbcconnection in bean.....

Hi developers..
How to develop jdbcconnection inside bean please send examples.
with regards
sure....:)-

you can use a bean for the jdbc connection. all you need to send to the bean is the data. and if you already know the tablename and the dsn then u can include it in the bean or you can change them dynamically.
for eg:
<jsp:useBean id="jb" class"...."/>
<jsp:setProperty name="jb" property="name" value="xyz">
inside the bean
public class qqq
String xyz;
public void setName(String name)
this.xyz = xyz; // data to be inserted for example
Class.forName(....);
.....// usual jdbc code to insert..
}

  • How to create an OrbtBehavior  bean and then initialize

    Greetings:
    Here's my problem:
    When I use OrbitBehavior as a standard piece of code from the J3D libraries it works, when I try to create a class and using the "extend" during the initialization, the code compiles,
    but I can't figure out how to connect the OrbitBehavior into the Canvas3D and the connect all the pieces to create some neat mouse action in a game I"m writing.
    Standard code:
    javax.media.j3d.Canvas3D canvas3d =
    new javax.media.j3d.Canvas3D();
    com.sun.j3d.utils.behavior.vp.OrbitBehavior orbitBeh =
    new com.sun.j3d.utils.behavior.vp.OrbitBehavior(canvas3d);
    orbitBeh.setSchedulingBounds(
    new javax.media.j3d.BoundingSphere(
    new javax.vecmath.Point3d(0.0, 0.0, 0.0),
    10000.0
    com.sun.j3d.utils.universe.SimpleUniverse virtualUniverse =
    new com.sun.j3d.universe.SimpleUniverse(canvas3d);
    virtualUniverse.getViewingPlatform().setViewPlatformBehavior(canvas3d);
    virtualUniverse.getViewer().getView().setBackClipDistance(10000.0);
    virtualUniverse.addBranchGroup(scenegraphBG);
    I've got as far as initializing a bean that is something like:
    class myBeh extends com.sun.j3d.utils.behaviors.vp.OrbitBehavior{
    In other object:
    class myObj extends javax.swing.JPanel{
    ** Note: this code is exteremely similiar to the old milkshapeViewer source code found somewhere like chumbalumsoft.com.
    The need to import using a Loader some MilkShape3D files is critical, and the OrbitBehavior code was about 3 lines long.
    As far as OrbitBehavior goes, the model flips around and zooms, but I need to control the reactions to the mouse and have been
    having an issue when settinup wakeupon... Criterion.
    That problem is, that I need more than one wakeup variable to defined (mouse movement, mouse button1, mouse button2, mouse wheel),
    KeyBoard keys, etc.
    Any suggestions on how to properly use OrbitBehavior and build a KeyHandler into com.sun.j3d.utils.behavior.vp.* based object would be
    greatly appreciated.
    Thanks again,

  • How to create dynamic entity beans at runtime (experts welcome)

    Hi,
    i have a question that i have been trying to figure out however i am still in search of an appropriate solution and thus ask you experts for guidance...
    I am developing a system to house data using ejbs.. however a have a problem i am trying to make the system very dynamic and some of the data that i am trying to store is dynamic in its nature..
    let me explain: i am searching for a solution that would allow a entity ejb to have a dynamic set of properties
    e.g.
    DataEntity could have one or many attributes but those attributes may be string, string, int, int
    or could be int, int, int
    or long, long
    or double..... or any configuration
    this DataEntity would linked to a TypeEntity that would act as a reference to know how to store and retrieve data..
    I have just come across JMX and dynamic Mbeans, and at first glance this seemed like it may be able to help but after further research i think this handles a different problem than i am facing.. (however might be wrong?)
    At the moment i am using toplink as the OR mapping but have also jsut started looking into hibernate..
    So far all i have come up with is to have a FieldEntity as a mappedsuperclass and have sub classes such as IntFieldEntity, LongFieldEntity.... which simple contain one field i.e int value, or long value..
    . and have DataEntity have a one to many relationship with the field superclass..
    the problem with this is how this gets mapped
    my ideal solution would be to have a dynamic DataEntity which could be generated at runtime and have all the required attributes for the particular type..
    so DataEntity would be a mappedsuperclass and then at runtime new types of DataEntity's could get spawned, database table created and OR mapping created linking?
    e.g.
    DataEnity1
    String attribute1;
    String attribute2;
    int attribute3;
    DataEnity2
    int attribute1;
    int attribute2;
    long attribute3;
    Has anyone ever created a structure like this or seen anything like this before?
    any advice would be appreciated
    regards,
    fg

    You cant add controls to the visual tree a runtime which persist beyond the lifetime of the application.  You will have to persist an indicator to your program which tells it to add the control.  Adding a control is as simple as initializing
    it and adding it to a parent already on the tree.  Controls can be created programmatically or using the XamlReader.Load static method.  You can find XamReader.Load in Windows.UI.Xaml.Markup in windows 8.1, Windows 8.1/Windows Phone unified
    projects.  For old windows phone ad just Silverlight I believe it is in System.Windows.Markup.
    Hope this helps.

    you will have to create a sequence and a trigger
    CREATE SEQUENCE <SEQUENCE NAME>
    INCREMENT BY  1
    START WITH  1
    NOCACHE
    /this sequence will guarantee that each requested number is unique
    the trigger will select from this sequence and insert the obtained value in the new record
    CREATE OR REPLACE TRIGGER <TRIGGER NAME>
    BEFORE INSERT ON <TABLE NAME>
    REFERENCING NEW AS NEW OLD AS OLD
    FOR EACH ROW
        BEGIN
            select
                <SEQUENCE NAME>.nextval
            into
                :NEW.<COLUMN NAME>
            from
                dual;
        END;
    [/CODE]
    this will always take the value from the sequence, even if you already provided a value yourself
    (otherwise you will first have to test if :NEW.<column name> is null, but I wouldn't do this for a key column.
    if you need the generated key back for further processing (inserting it into a child table for example), you can use the returning clause on the insert statement
    see the oracle documentation for more information about sequences, triggers and the returning clause

    I am new to Oracle and need to know how to create a table that uses an automatic incrementation on a primay key for it's default. I need the uniqueness automatically managed by the DBMS.. This activity is know as setting the Column (primary key with identity) in Ms-SQL..

  • How to Create adf table from java bean

    Hi,
    How to Create adf table from java class (Not from ADF BC).
    Thanks
    Satya

    @vlsn -- you have to follow what shay said.
    Do the following in Model layer ::
    create a table property java class with your columns setters and getters like :
    *public class gridProps {*
    private int sno;
    private String orderNum;
    *public void setSno(int sno) {*
    this.sno = sno;
    *public int getSno() {*
    return sno;
    *public void setOrderNum(String orderNum) {*
    this.orderNum = orderNum;
    *public String getOrderNum() {*
    return orderNum;
    Create another table java class which will populate the values to your column values and return the collection :
    *public class gridPopulate {*
    private  List<gridProps> gridValues ;
    *public List<gridProps> setToGrid(ArrayList<ArrayList> valuesToSet) {*
    *if (valuesToSet == null) {*
    return gridValues;
    gridValues = new ArrayList<gridProps>();
    if(btnValue.equals("completeBtn"))
    return gridValues;
    for(ArrayList<String> tempArr:valuesToSet)
    gridProps gp = new gridProps();
    gp.setSno(Integer.valueOf(tempArr.get(0)));
    gp.setOrderNum(tempArr.get(1));
    return gridValues;
    Right click gridPopulate class and create this as data control.This class will be seen in Data control list.Under this data control,Drag the grid property collection(created earlier) to your page.Then execute your binding(gridPopulate) according to your logic.

  • How to create combobox to display more than one columns

    I need kind help with the following question. As the combobox includes two pieces--textbox and the combobox list. Then how to create a combo box bean, which is based on table EMP(empno number(6), ename varchar2(40)) records for example, to achieve these features:
    1) allow more than one columns to be displayed in its records list--e.g., I need to show these records:
    empno (value) ename (label)
    103 David M Baker
    104 David M Baker
    105 Kelly J Volpe
    106 Krista F Carpenter
    107 Michelle P Silverman
    The two 'David M Baker's are different employees, but unfortunately, with the same name.
    2) allow combo box list to return the column value 'empno' even though it shows both columns as above. i.e., if user picks the second record above, then the combobox list returns 104 to the textbox in the background, but the 'David M Baker' is displayed on the textbox. Of course the combobox list may return 'David M Baker' if needed when there is only one column in the list as the current standard feature.
    3)allow partial match search by typing in some letters. i.e., if user types in the textbox of the combobox letter 'K' or 'k' then the partially matched records
    105 Kelly J Volpe
    106 Krista F Carpenter
    should be automatically displayed in the combobox list, not the whole list as above; then user may double click to choose one of the two or if user continues to type in 'R' or 'r', then the uniquely matched record 'Krista F Carpenter' is displayed in the textbox and the 106 is returned to the textbox.
    4) as a bonus if it's doable, allow combobox to return values to different textboxes when its records list has more than one columns.
    The reason I need these features is that I am working on the project migrated from Microsoft Access applications to centralized Java version web application. We at beginning promised to users community that Java swing will provide all the GUI user friendly features Microsoft Access has, but now we got stucked--we ate our words and got tons of complains from our users community. This is just the most needed component I posted here. I really hope that Java would add all the default GUI user-friendly features to compete with MS since its Win95 GUI has been accepted as industry standard. And most users are used to it. They claimed that they don't know and don't care what tool you use the newly created application should be more user friendly, not the opposite.
    I would be very much appreciated if any one would help me with this item.

    Thanks for your comments. I think nobody expects Sun to write everything including special features for its components. But I do think Sun should provide at least those standard user-friendly features for the GUI components because most users have been used to the GUI user-friendly features provided by Win95 and Access/Excel applications. Then this will help us to productively create applications to beat MS applications.
    Other wise like me, to get the existing GUI features, existed in old MS Access application, for our migrated Java application, I must re-create the GUI components library first which is a big burden to me at least, for others it might be fun for coding on their own from scratch, but I have to focus on the timing of project.
    If you really can pass the request to Sun and push them move a bit, please pass these words: before Sun starts to revise them, please play around window GUI, e.g., Access/Excel applications, then plan what to do, the bottom line is to equally match or better than them in FUNCTIONALITY(Look and feel is not my focus here). Don't ignore the influence of Windows regardless of you hate it or love it, the reality is most users are so familiar with windows GUI features which are accepted as industry standard. Thus the choice is to match or better to beat them. Don't make your car by closing your door, don't assume users will like what you come out in a closed room.

  • How to create different log files for each of web applications deployed in OC4J

    Hi All,
    I am using OC4J(from Oracle) v1.0.2.2 and Windows2000. Now I want to know
    1. how to create different log files for each of my deployed web applications ?
    2. what are the advantages in running multiple instances of oc4j and in what case we should run
    multiple instances of OC4J ?
    3. how to run OC4J as Windows2000 Service rather than Windows2000 Application ?
    Thanks and Regards,
    Kumar.

    Hi Avi,
    First of all I have given a first reading to log4j and I think there will some more easy way of logging debugging messages than log4j (If you could provide me a detailed explanation of a servlet,jsp,java bean that uses log4j and how to use log4j then it will be very helpful for me). The other easy ways (if I am not using log4j) to my problem i.e creating different log files for each of web applications deployed in oc4j are
    I have created multiple instances of OC4J that are configured to run on different ports and so on each instance I have deployed a single web application . And I started the 2 oc4j instances by transferring thier error/log messages to a file. And the other way is ..
    I have download from jakarta site a package called servhelper . This servhelper is a thread that is started in a startup servlet and stopped in the destroy method of that startup servlet. So this thread will automatically capture all the system.out.println's and will print those to a file. I believe that this thread program is synchronized. So in this method I need not run multiple instances of OC4J instead each deployed web application on single instance of oc4j uses the same thread program (ofcourse a copy of thread program is put in each of the deployed web applications directories) to log messages on to different log files.
    Can you comment on my above 2 approached to logging debugging messages and a compartive explanation to LOG4J and how to use LOG4J using a simple servlet, simple jsp is appreciated ...
    Thanks and Regards,
    Ravi.

    </ol>
    Adding a Panel to the Frame
    In this section, we will now add a panel to the frame. In the next section,
    we will add all the other components to this panel.</p>
    <ol>
    [*]In the Navigator, double-click <TT>HelloFrame.java</tt>.
    A viewer opens. This viewer has four tabs at the bottom:
    <ul>
    [*]Source, the currently active tab, which displays the source code
    of the selected class</li>
    [*]Design, which invokes a visual layout designer</li>
    [*]Class, which invokes an editor for the class' attributes, and
    can help you stay JavaBean complient</li>
    [*]Doc, which displays the class' JavaDoc
    </li>
    </ul>
    </li>
    [*]Click the Design tab.
    The viewer now displays a grey square, a graphical mock-up of your frame.
    Also, on the right-hand side of your screen, the Property Inspector opens.
    This allows you to quickly set attributes and define events for components.
    </li>
    [*]In the component palette (the tabbed toolbar near the top of your screen),
    select the Swing Containers tab.
    </li>
    [*]Click the blue square (described in rollover text as <TT>JPanel</tt>) and

    World!&quot; to display in the text field.</p>
    <ol>
    [*]In the Property Inspector, select the Events tab.
    </li>
    [*]Click the box next to the Action Performed field and press the Enter

    </li>
    [*]Close your application.</li>
    </ol>
    Refining the UI
    In this section, we polish the UI so that the components have the right size
    and alignment, the text in the text field shows up red, and the panel uses the
    portable GridBag layout instead of the JDeveloper-specific XYLayout.</p>

    This document describes how to create and run a very simple "Hello World"
    Java GUI app using JDeveloper. The application will have one button and one
    text field. Clicking the button will populate the text field with the message,
    "Hello World!"</p>
    [b]Creating The New Application
    In this section, we will create an application with an empty frame.</p>

    you need to work on at one time.
    </li>
    [*]Choose File | New Project.
    The Project Wizard opens. This wizard will help you create a new project called
    HelloGui. A project contains all the files that go together in one "tier"--for
    example, all the files belonging to a single Java Application client, or all
    the files belonging to an Enterprise Java Bean. Because we are working on
    a simple, one-tier application, we will only need one project in our workspace.

    [*]If the Welcome page appears, click Next.
    </li>
    [*]On the Project Type page, in the What is the Project's Filename?
