Using constructors in JApplet for passing variables?

Hello,
Some how I could not figured out, how to pass some parameters to the JApplet by using the constructors. Some how none of the constructors are invoked when I run the JApplet. I have to run it without html. How can I solve this problem?

public class K extends JApplet {
        //declared variables here
     public K() {
     public K(Data data) {
          System.out.println("******");
     public K(int kNo) {
                System.out.println("******");
          setKNo(kNo);
     public K(String kP) {
                System.out.println("******");
          setKP(kP);
     public K(String kP, int kNo) {
                System.out.println("******");
          setKNo(kNo);
          setKP(kP);
        //init method works fine
     public void init() {
          this.setSize(500, 500);
          this.setBackground(Color.BLACK);
          this.setPreferredSize(new Dimension(500,500));
          printer = new Printer(this);
          panel = new Panel(this);
          panel.repaint();
          this.add(panel);
          this.setVisible(true);
       //Other Methods ....
}* I tried to invoke all of the constructors, I added System.out.println("******"); to see if the constructors work fine but none of the overriden constructors were invoked. *

  • Using arrays as type for bind variable

    Hi all,
    I have this stored procedures that takes an array of strings as an argument:
    CREATE OR REPLACE PACKAGE mypackage AS
    TYPE StringArray IS VARRAY(100) OF VARCHAR2(16);
    PROCEDURE doSomething(v_strings IN StringArray);
    END;
    My java code looks something like:
    String[] strings = ...;
    CallableStatement cs = connection.prepareCall("CALL mypackage.doSomething(?)");
    cs.setObject(1, strings, java.sql.Types.ARRAY);
    calling the setObject method throws a SQLException: invalid column type.
    I have tried to change the call to:
    cs.setArray(1, new SqlStringArray(strings))
    where SqlStringArray is a wrapper around String[] that implements the java.sql.Array interface. This however throws a ClassCastException in oracle.jdbc.driver.OraclePreparedStatement. The latter is assuming it is receiving a class that implements yet another interface I guess.
    I also tried:
    cs.setObject(1, strings, java.sql.Types.VARCHAR);
    but that also throws a SqlException: invalid conversion requested
    Does anybody know how to bind String[] into a PreparedStatement?
    Any help is appreciated.
    Rudi.

    Made some progress. I am getting the OracleConnection from the WrappedConnection. This is a temporary solution for me so I would appreciate a final solution from anybody.
    I am now constructing a oracle.sql.ARRAY with an appropriate oracle.sql.ArrayDescriptor. I have found out that the type must be defined on a global level rather than in the scope of the package. Would be good if an Oracle expert could confirm that but I am happy to live with that.
    The IN parameter is correctly bound using the ARRAY instance but I am getting the following error when actually executing the statement:
    ORA-06512: Reference to uninitialized collection: at "BLUETEST_MYPACKAGE", line 57
    Now I have found quite some problem descriptions with that ORA error but all are dealing with OUT parameters that were not correctly initialized, i.e. the array constructor had not been called. In my case however, the array is initialized at by the java code and then bount to the sql statement. You would expect that the jdbc driver takes care of correctly initializing the PL/SQL collection wouldn't you.
    Does anybody know if I need to do anything extra?
    Many thanks,
    Rudi.

  • What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?

    Hi All,
    I am new to TestStand. Still in the process of learning it.
    What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?
    Thanks in advance,
    LaVIEWan
    Solved!
    Go to Solution.

    Hi,
    Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.

  • Can I use an OLE DB Command Task to call a parameterized stored procedure, perform some data editing and pass variables back to the SSIS for handling?

    I am using a Data Flow and an OLE DB Source to read my staged 3rd party external data. I need to do various Lookups to try and determine if I can find the external person in our database...by SSN...By Name and DOB...etc...
    Now I need to do some more data verification based on the Lookup that is successful. Can I do those data edits against our SQL server application database by utilizing an OLE DB Command? Using a Stored Procedure or can I sue straight SQL to perform my edit
    against every staging row by using a parameter driven query? I'm thinking a Stored Procedure is the way to go here since I have multiple edits against the database. Can I pass back the result of those edits via a variable and then continue my SSIS Data Flow
    by analyzing the result of my Stored Procedure? And how would I do that.
    I am new to the SSIS game here so please be kind and as explicit as possible. If you know of any good web sites that walk through how to perform SQL server database edits against external data in SSIS or even a YouTube, please let me know.
    Thanks!

    Thanks for that...but can I do multiple edits in my Stored Procedure Vaibhav and pass back something that I can then utilize in my SSIS? For example...
    One and Only one Member Span...so I'd be doing a SELECT COUNT(*) based on my match criteria or handle the count accordingly in my Stored Procedure and passing something back via the OLE DB Command and handling it appropriately in SSIS
    Are there "Diabetes" claims...again probably by analyzing a SELECT COUNT(*)
    Am I expecting too much from the SSIS...should I be doing all of this in a Stored Procedure? I was hoping to use the SSIS GUI for everything but maybe that's just not possible. Rather use the Stored Procedure to analyze my stged data, edit accordingly, do
    data stores accordingly...especially the data anomalies...and then use the SSIS to control navigation
    Your thoughts........
    Could you maybe clarify the difference between an OLE DB Command on the Data Flow and the Execute SQL Task on the Control Flow...
    You can get return values from oledb comand if you want to pipeline.
    see this link for more details
    http://josef-richberg.squarespace.com/journal/2011/6/30/ssis-oledb-command-and-procedure-output-params.html
    The procedure should have an output parameter defined for that
    I belive if you've flexibility of using stored procedure you may be better off doing this in execute sql task in control flow. Calling sp in data flow will cause it to execute sp once for each row in dataset whereas in controlflow it will go for set based
    processing

  • How can I pass variables from one project to another using Javascript?

    Hi all, I am trying to do this: let learners take one course and finish a quiz. Then based on their quiz scores, they will be sent to other differenct courses.
    However, I wish keep track on their previous quiz scores as well as many other variables.
    I found this nice widge of upload/download variables by CPguru (http://www.cpguru.com/2011/05/18/save-and-load-data-widget-for-adobe-captivate-4-and-adobe -captivate-5/). However, this widget works by storing variables from one project in local computer and then upload it to another project.
    My targeted learners may not always use the same computer though, so using this widget seems not work.
    All these courses resided in a local-made LMS which I don't have access to their code. Therefore, passing variables to PHP html files seems not work.
    Based on my limited programing knowledge, I assume that using Javascript to pass variables may be the only possible way.
    Can someone instruct me how to do this?
    Thank you very much.

    If you create two MIDlet in a midlet suite, it will display as you mentioned means you can't change the display style.

  • How do I use a Labview Enum as a Variable Parameter for Teststant

    I have a Labview VI that performs a relay setup based on a Port selection that is an Enumerated  Type Def. The Control comes in as a drop dwon box in test stand. The question is how can I use that same dropdown as a variable to pass into a subsequence. I am not sure how to get it to show up as a custom  Type in test stand. I am using Labview 8.2 and Test Stand 4.0
    Thanks,

    As of TestStand 2010 there is not a way to natively create enums in TS.  A quick google or bing search using "TestStand Enum" should reveal all those who have tried before you.  I believe that in the Ideas Exchange there is already a note to have TS do this and I'm positive the TS developers are aware...
    In answer to your question you will have to save it as a numeric and pass it down to the sequence.  Or I kinda like this idea:

  • How to use same CMOD code for 2 Diff. variableS?

    Experts,
    I have written some code under CMOD. Now, i have another query which i could use the same CODE, but diff. variable
    ( In the CMOD code, i am passing one User input variable ). For the 2nd query i have to pass different User Input variable.
    How OR what should i wright to tell CMOD, that IF its Query # 1 then use ABC variable and if Query # 2 then use XYZ .
    thanx

    Dear Hon Bon,
    Let us have a small example on ur scenario.
    Lets take the requirement as to calculate Month from Date. (In both the queries).
    Query 1: Input variable for Date is say  'ZDATE1'.
    Query 2: Input variable for Date is say  'ZDATE2'.
    Now let the CMOD variable be ZVAR_CALMONTH.
    when 'ZVAR_CALMONTH'.
        clear: lwa_var_rng,
               lwa_range.
        loop at i_t_var_range into lwa_var_rng where vnam = 'ZDATE1' or vnam = 'ZDATE2'.
          concatenate lwa_var_rng-low+0(4)
                      lwa_var_rng-low+4(2)
                 into lwa_range-low.
          lwa_range-sign = 'I'.
          lwa_range-opt  = 'EQ'.
          append lwa_range to e_t_range.
          clear lwa_range.
        endloop.
    Now when you execute the Query1,  the above code will work for 'ZDATE1' variable,
    if you execute the Query2,  the above code will work for 'ZDATE2' variable.
    So, the key point is,
    1. You need not worry about which query is getting executed. Whatever the query, the particular user entry variable of that query will be taken care.
    2. This method works only if the cmod variable (ZVAR_CALMONTH) is used in both the queries (Ofcourse its ur requirement).
    3. If queries have both the user entry variables then the cmod will work differently(it ll get data from both the user variables).
    You shall try ur code in the above example by replacing the code and the variable names and try playing around it.
    Hope this helps.

  • Passing variables using the URL

    in the past I have alsways used internal navigation methods
    within Flex - i.e. viewStacks, and linkBars etc... but I need to
    use an (existing) external menu and link (communicate) it to my
    Flex Application.....
    is it possible to pass variable to (into) a flex 2
    application using a URL
    e.g.
    http://...............
    ?page=homepage
    picking this variable ("page") up and getting its value (in
    this case "homepage")
    and then use the variable in the Flex application to display
    the relevent component...... ???
    basically, I am trying to navigate through a Flex application
    using an external menu system etc...... and displaying the
    particular components within the Flex application relevent to the
    select links (within the external menu system) communicating the
    two using a URL etc......
    thanks,
    Jon.

    Passing data into a Flex app using the url on startup
    requires working with the html handler, causing it to build
    flashvars in the Embed or Object tag. Inside Flex, these are
    accessed using the Application.parameters array.
    But it sounds like you want ongoing communication between the
    Flex app and the browser. For this you should use
    ExternalInterface. I have not used it at all, so I can't be any
    specific help.

  • How to use one variable as a default value for another variable?

    Hi Experts,
    Is it possible to use one variable as a default value for another variable?
    For example:
    Variable 1 = current calendar year month
    Variable 2 = mandatory input ready variable for calendar year month
    I want to use variable 1 as default value for variable 2, but also have the ability to change the month if required.
    Thanks!
    Kathryn

    u can use replacement path variable
    in that case u can replace the values of 1 variable with the another variable...
    but  u cannot do this setting
    u cannot make variable 2 as mandatory
    u cannot enter value for variable 2
    because by default it will take the value of variable 1
    u have to make follow settings
    variable 2
    name , technical name
    processing by = replacement path
    infoobject = ocalmonth
    next tab
    replaced by another variable
    variable name
    offset start , offset lenght
    save and hit okey

  • Handler called in library can only used passed variables?

    I have been redoing a 3000-line program to put handlers in an assortment of libraries.
    I've been getting a lot of variable undefined errors after calls to the handlers in the library.
    Previously, I declared global variables and the handlers, when they were in the same script, had no problem with them.
    Global variables do not seem to include handlers in called libraries as part of their scope.
    In fact, I can't even Set a new variable in one of these handlers, unless it has first been passed as a parameter in the handler call.
    For example, variable var1 in handler HandyHandler
    set var1 to 1
    results in a variable undefined error unless I call the handler:
    HandyHandler(var1)
    thus passing the variable from the main script.
    This is more than a little awkward.
    Is my perception correct:  all variables in a handler must be defined in the calling script and passed as parameters?

    It's hard to make advice without seeing actual codes. The boiled down essential version to demonstrate the problem would suffice. Also it might help to read the examples and explanations in the following threads.

  • Where used listing for Query Variables

    Can someone tell me how to get this list from the metadata repository or from the transport connector?

    Yeah I figured as much, but this is why I am thinking we have something missing, config or otherwise.
    Cause all I get when I do this is a new window with just the Variable details and nothing else, no where used list at all i.e.

  • Using Broadcaster to run a query for sequential Variable Values

    Hi SDN Community
    I came across a powerpoint slide regarding broadcasting which i hope to use in one of our reports.
    We are on SAP BW 35.
    Broadcaster has been used
    Your opinion would be greatly valued in regards to the direction i should proceed for our particular purpose.
    We basically have a report which is a web report.  This contains much html and javascript enhancements.
    But it essentially has queries with a series of variables.
    The customer would like the Queries to be cached for each variable value for performance reasons, on a daily basis.
    eg. Run the same query for Variable value BMABRM, then BMASRM, etc...
    In a loop fashion.
    Do not need to set a process chain to trigger broadcaster, or rather simply to schedule the broadcaster to run daily.
    I would basically then want to run this (cache) query in an iterative fashion, ie. rerun it for all the sites.
    Can you please make a recommendation to which is the best approach, whether a process chain should be set up, and any experience you may have had setting up a query to rerun for different variable values.  We would of course want the query to run successfully before rerunning it for the next variable to avoid locks, etc.
    Thank you in advance.
    Simon

    Hi Rahul,
    i have been trying to use the process chain functionality to do this but unsure how to do it.
    Which objects do you use in the process chain:
    Trigger Event Data Change (for Broadcaster)
    or Execute APD Model
    or Precalculation of Web Templates
    i am unsure how to incorporate the queries into the process chain.
    If you have any steps , it would be much appreciated.
    Thank you.
