Whare are the Classes?

Where are the Classes situated which we import while writing a JAVA code.
Import Java.Math
My question is where in JDK folder the class MATH is situated?

C:\jdk1.5.0_07\jre\lib
that is in jdk\jre\lib\rt.jar
use java decomplier to see Math.class
http://members.fortunecity.com/neshkov/dj.html
Give me duke dollarsMaybe you would have deserved some duke dollars if you had suggested that the OP simply looks at Math's source code - why decompile the class? If he had wanted to know it, that is.

    Benje001,
    Right-click on the CWAI control on your form. Choose Properties. The first tab is the Channels tab. After you choose your device from the drop down box on the right, you can type in the Channels box which channel you want to use.
    If you want to see a CWAI control that is already configured, all of the shipping examples will have this already done.
    Also, if you have questions about any item on the CWAI (or any other NI ActiveX control) you can click the ? icon in the right corner of the properties page and then click on the item in the dialog that you need help with. This "What's this" help will describe that particular control on the dialog.
    Hope that helps!

  • Weblogic Tuxedo Connector on 10gR3 - Where are the Classes?

    Hi everybody,
    I need some help developing an application using WTC. I am trying to build an application using Weblogic Workshop, but I am not able to find the class TuxedoConnection or TuxedoConnectionFactory that was mentioned on the documentation.
    I imported all jar files from \bea\wlserver_10.3\server\lib and still don't find this class. Do you have any idea where I find the correct jar or what is happening?
    Thanks,
    Rafael

    Hi Todd,
    thanks for your answer, but not all classes are there. TuxedoConnection and TuxedoConnectionFactory are examples of classes that are not inside weblogic.jar.
    I found where these classes are:
    <BEA_HOME>\module\com.bea.core.jatmi_1.2.0.3.jar

  • Whar are the ASAP methodologies?

    hi
    what are the ASAP methodologies, and what are the steps(technical) involved in that?
    thanks in advance,
    bye

    HI,
    Project plan, Business Blue print, Realization, Final preparation & Go-Live - support.
    1. Project Preparation: In this phase, decision makers define clear project objectives and an efficient decision making process (i.e. Discussions with the client, like what are his needs and requirements etc.). Project managers will be involved in this phase (I guess).
    A Project Charter is issued and an implementation strategy is outlined in this phase.
    2. Business Blueprint: It is a detailed documentation of your company's requirements. (i.e. what are the objects we need to develop are modified depending on the client's requirements).
    3. Realization: In this only, the implementation of the project takes place (development of objects etc) and we are involved in the project from here only.
    4. Final Preparation: Final preparation before going live i.e. testing, conducting pre-go-live, end user training etc.
    End user training is given that is in the client site you train them how to work with the new environment, as they are new to the technology.
    5. Go-Live & support: The project has gone live and it is into production. The Project team will be supporting the end users.

  • Are the Class E-book Settlement emails spam?

    Hello,
    I just received an email regarding a E-Book settlement, specifically "settlement ID Number: AP00020431. Reminder to Activate Your Credit" for the iTunes store. My question is this spam? Or a legitimate settlement. They list a website with the following address: www.ebooksagsettlements.com and activating iTunes store codes at //support.apple.com/kb/ht1574.
    If this is spam, thought apple users should know about it!

    Thanks for the info. I used your info to go to Apples redeem page and after pasting my code received $6.08. Not a lot but will pay for a album I was planning on purchasing. I'm sure many people will be reluctant to use the link in the email for fear of some password stealing, or keystroke recording site or the like. Using the redeem link on Apples page eliminates that problem.

  • What are the RFC's we use in XI

    Whar are the types of RFC we use in XI.
    Edited by: Harsha reddy on Jun 23, 2008 10:32 PM

    Hi
    The 5 basic types of RFCs
    Synchronous RFC (sRFC)
    Asynchronous RFC (aRFC)
    Transactional RFC (tRFC)
    Queued RFC (qRFC)
    Parallel RFC (pRFC)
    a good introduction into RFC and the different RFC types is the following article: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f078394a-4469-2910-c4bf-853c75674694
    Transactional RFC (tRFC)
    Transactional RFC (tRFC, also originally known as asynchronous RFC) is an asynchronous communication method that executes the called function module in the RFC server only once. The remote system need not be available at the time when the RFC client program is executing a tRFC. The tRFC component stores the called RFC function, together with the corresponding data, in the SAP database under a unique transaction ID (TID).
    Queued RFC (qRFC)
    To guarantee that multiple LUWs (Logical unit of work)are processed in the order specified by the application, tRFC can be serialized using queues (inbound and outbound queues). This type of RFC is called queued RFC (qRFC).
    qRFC is therefore an extension of tRFC. It transfers an LUW (transaction) only if it has no predecessors (in reference to the sequence defined in different application programs) in the participating queues.
    Implementation of qRFC is recommended if you want to guarantee that several transactions are processed in a predefined order.
    So if the Quality of service is Exactly once.. Trfc's used...
    if the Quality of service is Exactly once in order Qrfc's r used...

    The ALV object Grid methods allow the same functionality as ALV grid report function modules but are displayed within
    a screen (dialog program). SAP has provided a suit of programs which demonstrate how to For examples see standard SAP
    programs as detailed below:
    BCALV_EDIT_01 This report illustrates the simplest case of using an editable/noneditable ALV Grid Control.
    BCALV_EDIT_02 This report illustrates how to set chosen cells of an ALV Grid Control editable.
    BCALV_EDIT_03 In this example the user may change values of fields SEATSOCC (occupied seats) and/or PLANETYPE.
    The report checks the input value(s) semantically and provides protocol messages in case of error
    BCALV_EDIT_04 This report illustrates how to add and remove lines to a table using the ALV Grid Control and how to
    implement the saving of the new data.
    BCALV_EDIT_05 This example shows how to use checkboxes within an ALV Grid Control. You learn:
         (1) how to define a column for editable checkboxes for an attribute of your list
         (2) how to evaluate the checked checkboxes
         (3) how to switch between editable and non-editable checkboxes
    BCALV_EDIT_06 This example shows how to define a dropdown listbox for all cells of one column in an editable ALV
    Grid Control.
    BCALV_EDIT_07 This example shows how to define dropdown listboxes for particular cells of your output table.
    BCALV_EDIT_08 This report implements an ALV Grid Control with an application specific F4 help. The following aspects
    are dealt with:
         (1) how to replace the standard f4 help
         (2) how to pass the selected value to the ALV Grid Control
         (3) how to build an f4 help, whose value range depend on a value of another cell.

  • Report template : where are defined the class

    Hello,
    I'm looking where the class are defined, such used in "before rows"
    <td><table cellpadding="0" border="0" cellspacing="0" summary="" class="t1standard">
    I'd like to add by owns or to modify existing one.

    Hello,
    It's in the css file if you open up the page template there should be something like.
    <link rel="stylesheet" href="#IMAGE_PREFIX#carl/theme_1/theme_V2.css" type="text/css" />
    and thats the css file that is being used by your pages. Either edit that file (discouraged) add another file right after it it that overrides the classes you want to change or just change it inline in the page header or the template.
    Take a look at this http://www.brainjar.com/css/using/

  • What are the benefits of converting my custom class into Data Control?

    Hi,
    I have developed my own custom class which implements no of methods for execution of Business Logic. Now I have two ways to use the same -
    *1. Create and instance of the same (wherever required) and call those methods.*
    *2. Expose the class as Data Control.*
    I want to understand which methods/technique is better and why?
    Does creating that class as Data Control provides me better performance any other benefit.
    Thanks in Advance,
    Amit

    Hi,
    1. You use this if you don't want to use ADF bindings to access the business logic (e.g. to build input forms or table for it)
    2. You use this when you want to work with ADF. Additional benefits you gain is that you can specify UI control hints on the generated metadata, apply validation rules that are consistently applied to all uses of the POJO class. In addition you don't need to handle class instantiation and dismissal yourself anymore as the ADF framework takes care of it.
    The base line though is "no data control - no ADF binding"
