Create a textfile in java

Hello!
I got two questions:
1) If I have a catalog called "temp" how can I controll how many textfiles there are stored in the catalogue? I want to read every textfile that is stored in there.
2) Is there any simple way to create a new textfile from a javaprogram
into a specific catalog?
Thanks for helping me// MiMa

Hello again!
Thank you for your kindness ;-)....giving me the link
Of course I know how to read/write from an EXCISTING file.... but I've never been creating a NEW file in a javaprogram. Maybe I didn't explain myself to well?
It says in the tutorials that the file I want to read/write from/to must be placed in the same catalogue so my conclusion is that the file must EXCIST before I work to the file...or Am I wrong?
And of course I've been searching in the javacommunity and in the tutorials before I posted this "fundamental question" but with no result. And I have to do this "cataloguething" otherwis I haden't made a question about it.
So what should I do?
Thank you for helping me!

  • How to create web services in java?

    Hi,
    I am a newbie to java webservices. Can anybody tell me how to create web services in java?
    Any tutorial link or step by step doc would be useful.
    Appreciate your help in this regard.
    Thanks in advance.

    Creating web services in Java appears to depend highly upon the server you intend to use.

  • Created in Web dynpro Java or Web dynpro ABAP

    hi all,
    I have a web application running. Its UI  is created either in web dynpro java or web dynpro ABAP. Is there any way by which we can find out that in which form of UI technology is it created; in web dynrpo java or web dynpro ABAP ?

    Hi,
    I am really not sure if this is recommended..
    Try some negative testing on the application. If the application crashes, the trace of the error occured will tell you what kind of development has been adopted for the Web Dynpro application.
    Another hint can be the port number in the Application URL. If it is not 50xxx, and is somewht like 8xxx, it is surely Web Dynpro for ABAP.

  • How to create and instance of Java Object from an XML Document.

    Hi,
    How can we use a XML Document to create an instance of Java Object and do vice versa ie from the Java Object creating the XML Document.
    XML Document is available in the form of a String Object.
    Are there helper class available to achieve this.
    I need to do this in a Servlet.
    Regards
    Pramod.

    JAXB is part of JavaSE while Xmlbeans claims full schema support and full infoset fidelity.
    If the standard APIs do all that you need well then use them.

    Ask in the ID forum and be much more specific about your configuration. there could be any number of reasons why manifests, temp files or restore files are created.
