Where to place text file in Jdeveloper9irc to read from Java program

For ex.
package mypackage;
import java.io.*;
public class ReadData
public ReadData()
public static void main(String[] args)
new ReadData();
try{
File fin = new File("test.txt");
if (fin.canRead())
System.out.println("Can read file");
I am geting a error message of file not found. Please advise
in which directory should I place the text file "test.txt" so that the java program can read from it.
Thanks,
agsp

The test.txt file should be in the 'Run Directory" of your Project. Select Project.jpr and invoke Project settings dialog.
Click on the Runner. You will see the "Run Directory" edit field.
For ex.
package mypackage;
import java.io.*;
public class ReadData
public ReadData()
public static void main(String[] args)
new ReadData();

How to create .a files for iPhone applications

Hi guys,
I am working on iphone library in Objective-C and I need to create .a files in this library. Please let me know if anybody knows how can I create the .a files from .m files in Objective-C.
Thanks in advance,
Ishita

hello,
it is not officially supported. however, it can be done when you write your own makefile. how to call the compiler and necessary flags and so on see the "build results" output of xcode. it's like
/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.0 -x objective-c -arch i386
and so on. after you created the object files you create the library with the archive tool, like
ar -crv libwhatever.a Dada.o Bubu.o AnotherOne.o

How to call c functions that expects c structs from java program?

i need to call from my java program to c functions that get
c structs as a parameters in their prototype.
as you probablly know java is not working with structs (classes only), so my question is how can i do it , i mean call the c functions that gets structs as parameters form java????

i believe your c function can accept a jobject and then inside your c function you have to translate that jobject into a c struct by using the jni methods.
the only reason your c function cant accept structs from java is because java does not have such structures. your c function can accept any data type that has been defined and a jobject has been defined.
if you have no control over the c functions that are being called, you need to write a wrapper function for those c function. the wrapper functions do the translation from jobject to a struct...then call the c other c functions.

How to create an event in web application?

Hi,
I am creating online auction application. I need to have an event trigerred when an auction on an item is finished. How can I do that?
Thank you

You could use the Observer design pattern...You'll find plenty of litterature on the subject.
You'd also want to take a look at how they implement the feature you're looking for in existing auction applications, like Sun's :
http://developer.java.sun.com/developer/onlineTraining/Programming/JDCBook/code.html
Sourceforge's Gavel, which is open source, so you can browse the CVS repository to look for source code :

How to create a file in the server?

Hi,
I'm making a webservice that has to generate a XML file, sign it using another webservice and return this XML. The problem is that i don't know how to create the file in the server throught webservice.
I use this code in the webservice to generate the XML and after I return the XML to client in a byte[]
     static void outputDocumentToFile(Document myDocument, String path) {
        //setup this like outputDocument
          try {
               // XMLOutputter outputter = new XMLOutputter(" ", true);
               XMLOutputter outputter = new XMLOutputter();
               //output to a file
               FileWriter writer = new FileWriter(path);
               outputter.output(myDocument, writer);
               writer.close();
          } catch(java.io.IOException e) {
               e.printStackTrace();
    }But the file is generated in the client-side, how can I generate the file in the server-side?
Thanks very much.

Well the File object doesn't create a file it's simply an abstract representation of file and directory pathnames.
You can try something like this:
<%
try
// get the path to the web server root
// I read somewhere not to use 'getRealPath' for some reason which I
// can't seem to remember :S Hopefull someone can enlighten us :)
String path = application.getRealPath("/project/jsp/demo.txt");
File file = new File(path);
PrintWriter writer = new PrintWriter(new BufferedWriter(new FileWriter(file)));
writer.println("Hello World!");
writer.close();
catch (Exception e)
System.err.println(e.getMessage());
%>
Hope this helps :)

How to share HttpSession between different web application ?

I have two web application ( ie two different war files), I discovered that the jsp in the two war files are not able to share the HttpSession, may I know how to you share the HttpSession between two different web application ?

From the api doc:
"Session information is scoped only to the current web application (ServletContext), so information stored in one context will not be directly visible in another."
You can not share a Session object between web apps. You can create your own sessions using a database, textfile or hashmap. Do a search on the O'Rielly web site for psuedo-sessions.

I am working in windows 7 and I am trying to enable the copy/paste and I can not find user.j file in the profile and I am not real sure how to create a file, I can create a folder .

I am trying to copy text from a word document and paste it into my web builder and it says that firefox does not support copy/paste from clipboard. Went to your site and it tells me to open the user.j file in my profile. This file does not exist and I am not real sure how to create that file so I can paste the fix from your site into it.

I went to that link and added to firefox add on but it still does not work. I went to the add on option button for this but it told me that my MYSIWG widget was disabled. Does this have something to do with it not working and if so how do you enable it.

3. Set the source property of this Interactive From UI element to the context pdfSource.
4. Insert a button which would open your pdf file.

How to create txt file in utf-8?

Hi,
if i create a txt file using vb in fdm, it is created with the ansi encoding. Is there any option how to create this file in utf-8?
Thx

Forms6i uses Oracle 8.0.6 client libraries. MetaLink Note 207303.1 lists supported client/server configurations, and the last database version supported with those libraries is Oracle 9.2. The only exception is made for e-Business Suite (Oracle Applications). Therefore, you configuration is not supported.
Anyway, Oracle 8.0.6 does not support AL32UTF8 well. You should select UTF8 as the database character set (not national character set!). You need to select a check box on DBCA interface (possibly unavailable in fast/default installation path) which allows you to see non-recommended character sets.

How to create backup file on itunes for ipod touch 4g game apps data? Is there a way to do it? I want to try an app on my friend's computer, but you can't add apps on another computer without having your own ipod's data being deleted. Thx for any help!

How to create backup file on itunes for ipod touch 4g game apps data? Is there a way to do it? I want to try an app on my friend's computer, but you can't add apps on another computer without having your own ipod's data being deleted. Thx for any help!
I want to know how to create a backup file (because I'm pretty new with itunes, and it's hard to use it for me still), how to store my app data/media/videos, etc. And how I can retrieve them back when I'm done with the app I tried on my friend's computer.
If anyone can help, it'd be great! Thank you so much!

Sure-glad to help you. You will not lose any data by changing synching to MacBook Pro from imac. You have set up Time Machine, right? that's how you'd do your backup, so I was told, and how I do my backup on my mac. You should be able to set a password for it. Save it. Your stuff should be saved there. So if you want to make your MacBook Pro your primary computer, I suppose, back up your stuff with Time machine, turn off Time machine on the iMac, turn it on on the new MacBook Pro, select the hard drive in your Time Capsule, enter your password, and do a backup from there. It might work, and it might take a while, but it should go. As for clogging the hard drive, I can't say. Depends how much stuff you have, and the hard drive's capacity. As for moving syncing from your iMac to your macbook pro, should be the same. Your phone uses iTunes to sync and so that data should be in the cloud. You can move your iTunes Library to your new Macbook pro
you should be able to sync your phone on your new MacBook Pro. Don't know if you can move the older backups yet-maybe try someone else, anyways,
This handy article from Apple explains how
How to move your iTunes library to a new computer - Apple Support''
don't forget to de-authorize your iMac if you don't want to play purchased stuff there
and re-authorize your new macBook Pro
time machine is an application, and should be found in the Applications folder. it is built in to OS X, so there is nothing else to buy. double click on it, get it going, choose the Hard drive in your Time capsule/Airport as your backup Time Machine and go for it. You should see a circle with an arrow on the top right hand of your screen (the Desktop), next to the bluetooth icon, and just after the wifi and eject key (looks sorta like a clock face). This will do automatic backups of your stuff.

How to create pdf files in UNIX directory from oracle reports

I would like to know how to create pdf files in UNIX directory from oracle reports.
Thanks,

Please make your question more clear . Also mention the reports version.
1) If you are runnning reports in Unix, you can give
.... destype=file desformat=pdf desname=<filename>
in command line
Please refer docs below.
2) If by your question you mean
"My reports server is running in Windows but I want to ftp my files to Unix after creating it"
then the answer is that you can use pluggable destination "ftp"
.... destype=ftp desformat=pdf desname=<ftp url>

How to get the web application root ?

Hi,
We are developing a JSP/Servlets web application for Weblogic 5.1, that is distributed as a WAR archive, and so far we are unable to determine the web application root dynamically (from within the code in a Servlet or class). We tryed the servletContext.getRealPath("/") method, but it is not working due to the fact that we are deploying the application as a WAR file.
We need to have this app root at the application startup, because it is widely used inside the JSP pages and the servlets of the web application. Also we would like to avoid setting it as a static parameter in the web.xml or elsewhere.
Does anyone know how to do that? Any hint or suggestion is very much appreciated!
TIA
Stefan Buynov

Thanks for your reply.
As I said in one of my early posts, this variable (the application root) i used widely in the application (not only in JSPs, but also in classes).
Another problem will be including JSTL in the project - first of all, I will have to put this tag where the variable is required (it will be quite exhausting), and also the specification of the application is strict - I might not be able to add this tag library, since the client won't like it.
Anyway, thanks for your concern.
Regards,
Stefan
