How to generate a class automatically in JDev

Suppose from OS side, I create a new empty Java file in the src directory of a project in JDev. Then in JDev, I click on the "refresh"/reload button for that project. Now I see the new java file. Double click it to open it; it is blank. In this case, how can I generate a class using the file name as the class name, and a default constructor or even a main method etc.?
Is there any convenient way of doing this, rather than going to the usual route, which is File menu, then new, java file, from that UI to give a class name, choose to include a main method etc..
Thank you.

Not exactly your case, but you should get the idea.

    How to invoke a java class automatically using Quartz scheduler or any other simplified way
    I am trying to schedule a job in my web application and need to understand conceptually How to make it work using quartz . The job is scheduled to be executed at 4 pm daily. Am testing the same and It works well when i run it as standalone application manually.
    How to configure it that when i start my aplication it should run at its own through quartz.
    I am avoiding use of servlet init method and java timer though any alternatives there?
    Thanks for your help.

    I've not see quartz... are you in Windows, Solaris, Linux, or Mac?
    Are you using JAR files or class files?
    Windows: javaw myClass (I cannot remember right off if you have to have the .class on the end)
    Windows: java -jar myJAR.jar
    Solaris java -jar myJAR.jar
    Linux java -jar myJAR.jar
    Mac?

  • How to generate web.xml automatically?

    Hi all!
    I am new to servlets. I have configured the tomcat 5.5.9 with eclipse 3.0 succussfully. It is generating the class files. But I want to know how to generate web.xml through it.
    Thanks in advance...
    Code Snooker

    AFAIK, there's no template for generating web.xml.
    Navigate to <TomcatInstallDir>/webapps/
    You would find lot of directories - each one being a web application.
    Navigate to any one, say ROOT and then to the WEB-INF directory
    under that.
    You would find a web.xml.
    Copy it into your <web-application-dir>/WEB-INF folder and make necessary changes

  • How to generate customer invoices automatically?

    We are doing direct debit for some of our clients based on the billing plan. 
    I know that it is possible to create customer invoices automatically based on the billing plan, but do not know the details how to trigger the process.
    Imagine I have created the billing plan for the billing WBS-element.  What should be done next to post the customer invoice automatically?
    Many thanks for your help!

    Hi Mrinal,
    I do not know much about SD process, in fact I am mostly interested in FI invoices to be generated and posted while having the most dummy SD flow possible.
    What exactly does VF04, what are prerequisites to run it, and what are the follow up steps?  My starting point is the billing plan maintained for the WBS-element, while the target is FI customer invoices posted, so what are the missing steps in between?
    Many thanks.

  • How to generate item codes automatically

    Hi,
    My customer wants that the inventory item code be generated automatically based on its description. The code should have:
    - 3 first characters of the description
    - A sequential increased number, to make the code unique.
    e.g. the item called "Petrol" should have the code "pet004".
    To achieve this, I have created a database procedure. So the user that works in "Item Master" form, will fill out "description" field and the "Item" field should be automatically populated based on the return value of this procedure.
    Is there any way how to achieve this through personalization?
    Or, is there any standard way that Oracle offers for automatic generation of item codes?
    Thank youl

    Hi,
    You have to do it using forms personalization.
    Thanks,

  • How to generate a query automatically?

    Hello,
    I set up a PreparedStatment pstmt = conn.prepareStatment(" select distinct ? from table ")
    and then
    pstmt.setString(1, "country")
    and I use ResultSet rs = pstmt.executeQuery()
    but the result is not what I expect.. It only returns "country"
    if I change it to stmt = conn.createStatement("select distinct country from table")
    it works
    So, how can I generate a query like this automatically?
    Thanks!

    The query you posted means "return the first argument once for every row in the table called 'table'." What is it you are trying to do?
    And, you may want to post this on the JDBC forum rather than here.

  • How to generat code numbers automatically?

    Dear members,
    i have 3 tables with code no which are primary key and char datatype.
    the first code number is 2 characters,
    then the 2nd code number is 5 characters
    then 3rd code number is 9 characters.
    the first table's code numbers are manually defined. 10, 20, 30 and so on.
    but the requirement is to generate the 2nd table's code number automatically by fixing the 1st tables 2 characters on the left and then 10001, 10002, 10003, 10004 and so on.
    and like this the 3rd table's code number to be generated by fixing the first 5 characters on the left from the 2nd table and the 4 characters on the right 100010001, 100010002, 100010003, 100010004 and so on.
    for example:
    FIRST TABLE 2ND TABLE 3RD TABLE
    10 10001 100010001
    10002 100020001
    20 20001 200010001
    20002 200020001
    30 30001 300010001
    30002 300020001
    How can do this job?
    i issue the following query.
    declare
    v_2nd_code_no char(5);
    begin
    select max(2nd_code)+1 into v_2nd_code_no from 2nd_table;
    select first_code_no||v_2nd_code_no into :blk.item from dual;
    end;
    it give the following error.
    ORA-06502: PL/SQL: numeric or value error string
    now how can i do this job.
    thanks in advance.

    Muhammed,
    I think you should reconsider your design. Duplicating data into other columns will give you update headaches, uses extra storage, and fool the optimizer, and maybe others will point out more disadvantages.
    In my opinion your table should look like this:
    code1 number(2,0)
    code2 number(3,0)
    code3 number(4,0)
    Please note that they are numbers! Using numbers for numbers is the right way for not fooling the optimizer. Before executing a query, Oracle determines the access path to retrieve all information, based on statistical information on all the tables,columns and indexes involved. If you issue a query with a predicate like:
    code3 between '100019999' and '100020000'the optimizer will think there are numerous strings between the two "numbers" and will maybe head towards a full table scan, or at least think there are thousands of values between the two.
    Now, if in your application you want to get a nicely displayed number with leading zeros and all, you just use:
    rpad(to_char(code1),2,'0') || rpad(to_char(code2),3,'0') || rpad(to_char(code3),4,'0')Regards,
    Rob.

  • How to generate swf file automatically on server ?

    Hi. I'm new to flash and i've just learnt how to use OSMF to build a flash player. My question is very basic and i hope to put it as clearly as i can:-
    Now i can create a flash player from flash builder. But in order to point to a new location for the video, i need to recreate the swf from flash builder. So how would i generate a new swf or change the video address on the server when a user uploads a new video. Of course i can't afford to build the project in flash builder myself every time a video is uploaded !
    I think the answer incldes flex, that's why i'm asking here. Thank you.

    For what you're using it for, it sounds like you would do better to create one SWF that can have different data fed into it, either by loading external data such as XML, or by using application paramters (flashVars). Use this data to determine the correct location of the video.
    However, it is possible to compile server side using the mxmlc and/or compc compiler. For example, I use Apache Ant to compile themes on the server-side, which then get loaded into an app at runtime. IMHO, this method should only be used for compiling "resources," and not used for compiling "information," as your post suggests.

  • How to generate BSP application automatically

    Hi, BW experts,
        I get some web interfact from transport, for example: Z1, Z2. I failed to run them on the web, then I check the BSP application in SE80 are not generated.
        I use BPS_WB to generate the web interface, selected "save customizing", "Generate BSP Application (Again)" and "Generate Class (Again)".
        then I got the log with green color said "Activity terminated"  , I go to check BSP application but it still not generated.
    anyone can help ?
    Regards

    Jie Miao,
    Which version of BPS are you on?  I worked through an similar issue last week on SEM-BPS 6.0 on NW04S where introduction of a new authorization object S_ICF_ADM gave me false positive on generate and we had issues also with transports even thought no error since the transport id did not have that new object.  This client had security locked down pretty tight.

  • Best Practice for WSDL Generate Proxy Class for Web Service with Two Versions

    Dear All
    Thank you in advance for you help.
    I would like to generate proxy classes for same function but with two versions.
    Old version web service (v23.2) is used for stable modules in a project which is not going to modify.
    However, enhancement is added in new version web service (v24) and is going to use in any future modules.
    For example,
    wsdl.exe -o="TestProxy.cs" -l:CS -n:Test -sharetypes https://community.workday.com/custom/developer/API/Notification/v23.2/Notification.wsdl https://community.workday.com/custom/developer/API/Notification/v24.0/Notification.wsdl
    It generates similar classes with an '1' added at the end of the class name.
    ublic partial class Event_TargetObjectType {
    private Event_TargetObjectIDType[] idField;
    public partial class Event_TargetObjectType1 {
    private Event_TargetObjectIDType1[] idField; ...}
    Since the function inside some class is the same, is it possible for WSDL.exe to generate proxy classes automatically that if the class is the same, then generate one class only (sameFunction())  but if it detects the class is different, then add '1'
    to the end of class name (differentFunction() and differentFunction1())
    i.e.
    public class sameFunction()
    public class differentFunction()
    private int a;}
    public class differentFunction1()
    { private int b;
    Best Regards
    mintssoul

    Hi  mintssoul,
      As per this case, I have shared corresponding details below :
    1.As far as I know, WCF doesn’t support method overloading directly
    2.Because WSDL doesn’t support method overloading (not OOPs).
    3.WCF generates WSDL which specifies the location of the service and the operation or methods the service exposes.
    4.WCF use Document/Literal WSDL Style : Microsoft proposed this standard where the soap body element will contain the web method name.
    5.By default all the WCF services conform to the document literal standard where the soap body should include the method name.
    6.but you can differ the method in the same manually by using Name attribute like below 
    For example:
        [OperationContract(Name="Integers")]
        int Display(int a,int b)
        [OperationContract(Name="Doubles")]
    double Display(double a,double b)
    7. Or I suggest you that can use svcutil to map multiple namespaces for generating wcf service proxies .
        for more information about this, refer here :

  • Generate  primary key automatically

    Hi, I'd like to know how to generate primary keys automatically with JHeadStart because when I try to make an insert into a table, the page gives me the option of insert the primary key of the register.
    Thanks a lot

    I have a table which have 2 fields, one of those is the primary key, the other is the description.
    I have established the primary key as a DBSequence, but when I try to insert a new record testing the service, appears a negative number in the primary key and instead of that I want to appear the correspondent key, or if doesn't appear the correct value, the insert be done correctly.
    At least I change manually the value if this key, the insert can't be done.
