Import iCal into another program

Is it possible to export a calendar that's in iCal and import it into another program? In other words is there a way to share my calendar with a non-mac user other than through a .MAC account?

With the release of iCal 3 in Mac OS X 10.5 and iCal Server with Mac OS X 10.5 Server in the near future, this will be possible, as iCal has been rewritten to conform with the the emerging CalDAV standard. It's not possible to do using iCal at the moment, as it does not have the capability to host read-write calendar objects.
There is an open-source version of the iCal Server: Darwin Calendar Server.
You won't need .Mac to do this, but in any event, .Mac cannot interact with computers not running OS X, eliminating the one you want to share calendar data with.

Importing XML into Java. Help needed Please!!!

Hi,
I have downloaded j2sdk1.4.1_05 and want to configure it to import XML files into a DOM in Java. I am having trouble doing this and need help. I read that version 1.4 support JAXP 1.1 but I am having trouble finding the JAXP-api.jar file. It says to put all the other Jar files into a folder and leave the JAXP-api.jar.
Could you please tell me how to set up Java so that I can import an XML file. I also downloaded JAXP 1.2. But there seems to be no installer.
Thanx John

You can learn about reading xml in java by reading the J2EE tutorial at
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/
Here is sample program to read XML file into a DOM taken from this tutorial
(http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JAXPXSLT4.html)

        factory.newDocumentBuilder();
      document = builder.parse(f);
    } catch (SAXParseException spe) {
      // Error generated by the parser
      System.out.println("\n** Parsing error"
        + ", line " + spe.getLineNumber()
        + ", uri " + spe.getSystemId());
      System.out.println(" " + spe.getMessage() );
      // Use the contained exception, if any
      Exception x = spe;
      if (spe.getException() != null)
        x = spe.getException();
      x.printStackTrace();
    } catch (SAXException sxe) {
      // Error generated by this application
      // (or a parser-initialization error)
      Exception x = sxe;
      if (sxe.getException() != null)
        x = sxe.getException();
      x.printStackTrace();
    } catch (ParserConfigurationException pce) {
      // Parser with specified options can't be built
      pce.printStackTrace();
    } catch (IOException ioe) {
      // I/O error
      ioe.printStackTrace();
} // main
} If you have java 1.4 sdk installed everything should compile and run. Separate
JAXP package is nor required - JAXP is included in rt.jar in java-home-directory/jre/lib.

Import tool into java application.

I'm creating a java web service & would like to know if there is a way to import a .exe file into the application so that it can be used in windows with having to be on the customers machine.

I'm sorry, you're firmly in WTF territory here.
That's a command to load an application via Java Web Start. It loads it from the server at 192.168.1.1. Running a Web Start application, once it's loaded onto the client, does not involve a browser. But getting it installed on the client does involve a browser.
And you can configure a Web Start application to create a shortcut. You don't need to do it yourself, least of all from the application to which the shortcut should refer.
I also don't understand the reference to "web services" and "turning the application into a web application", but probably your use of those phrases isn't related to their actual standard meanings.
My advice: use Java Web Start in the way it was meant to be used. It works just fine that way. Don't try to help it out if you don't know what you are doing. Which you definitely don't, if I am understanding your idea correctly. Which I might not be.

Import J2ME source into Java ME SDK 3.0

Hi,
Im new to Java ME.
The internet has lots of J2ME examples for games(but none for Java ME SDK 3.0), and im trying to import these into Java ME SDK 3.0 . I click on new project and select 'Import Wireless Toolkit Project', but it doesn't detect a project. Ive tried this with several popular J2ME samples.
Anyone know how to do this right, so I can import J2ME projects into Java ME SDK 3.0 completely, with classes, packages and resources intact?
I tried making a new project, and then copying the files into the relevant directories too. All the classes show up in the SDK, but on running the program no app is displayed in the emulator.

Don't double post. I've removed the thread you started in the Java Programming forum with the identically same question.

Also please let me know about how to connect internet through proxy server.As I said above, if you are using the Apache HTTP client, no we can't, as this is not an Apache forum. I also told you where to find that answer.
If on the other hand you don't want to use that client any more, setting the system properties http.proxyHost and http.proxyPort will do it for java.net.HttpURLConnection. See the Java Custom Networking tutorial for examples.

Can I use a C/C++ xml parser in my java program?

Hi,
How can I use a C/C++ xml parser in my java program?
Elvis.

You would still need to convert the XML data structure into a Java data structure to import it into Java.
Don't assume you need C++ to do anything. I woudl write it in Java first, then profile the application to see where the bottle necks are and then optimise them
Don't optimise code unless you have proof it needs to be optimised.
If you want to improve the speed of reading XML, try XMLbooster

New TO JAVA Programming

Dear Forummembers,
I am student doing postgraduate studies in IT.i have some queries related to one of my programming staff.i am very much new into Java programming and i am finding it a bit difficult to handle this program.The synopsis of the program is given below -
You are required to design and code an object-oriented java program to process bookings for a theatre perfomance.
Your program will read from a data file containing specifications of the performance,including the names of the theatre, the play and its author and the layout of the theatre consisting of the number of seats in each row.
It will then run a menu driven operation to accept theatre bookings or display the current
status of seating in the theatre.
The name of the file containing the details of the performance and the theatre should be
provided at the command line, eg by running the program with the command:
java Booking Theatre.txt
where Theare.txt represents an example of the data file.
A possible data file is:
Opera
U and Me
Jennifer Aniston
5 10 10 11 12 13 14
The data provided is as follows
Line 1
Name of the Theatre
Line 2
Name of the play being performed
Line 3
Name of the author of the play being performed
Line 4
A list of the lengths (number of seats) of each row in the theatre, from front to
back.
The program must start by reading this file, storing all the appropriate parameters and
establishing an object to accept bookings for this performance with all details for the theatre
and performance.
The program should then start a loop in which a menu is presented to the user, eg:
Select from the following:
B - Book seats
T - Display Theatre bookings
Q - Quit from the program
Enter your choice:
And keep performing selected operations until the user�s selects the quit option, when the
program should terminate.
T - Display Theatre bookings
The Display Theatre Bookings option should display a plan of the theatre. Every available
seat should be displayed containing its identification, while reserved seats should contain an
Rows in each theatre are indicated by letters starting from �A� at the front. Seats are
numbered from left to right starting from 1. A typical seat in the theatre might be designated
D12, representing seat 12 in row D.
B - Book seats
The booking of seats is to offer a number of different options.
First the customer must be asked how many adjacent seats are
required. Then start a loop offering a further menu of choices:
Enter one of the following:
The first seat of a selected series, eg D12
A preferred row letter, eg F
A ? to have the first available sequence selected for you
A # to see a display of all available seats
A 0 to cancel your attempt to book seats
Enter your selection:
1. If the user enters a seat indentifier such B6, The program should attempt to
reserve the required seats starting from that seat. For example if 4 seats are
required from B6, seats B6, B7, B8 and B9 should be reserved for the customer,
with a message confirming the reservation and specifying the seats reserved..
Before this booking can take place, some testing is required. Firstly, the row
letter must be a valid row. Then the seat number must be within the seats in the
row and such that the 4 seats would not go beyond the end of the row. The
program must then check that none of the required seats is already reserved.
If the seats are invalid or already reserved, no reservation should be made and the
booking menu should be repeated to give the customer a further chance to book
seats.
If the reservation is successful, return to the main menu.
2. The user can also simply enter a row letter, eg B.IN this case, the program should
first check that the letter is a valid row and then offer the user in turn each
adjacent block of the required size in the specified row and for each ask whether
the customer wants to take them. Using the partly booked theatre layout above, if
the customer wanted 2 seats from row B, the customer should be offered first:
Seats B5 to B6
then if the customer does not want them:
Seats B10 to B11
and finally
Seats B11 to B12
If the customer selects a block of seats, then return to the main menu. If none are
selected, or there is no block of the required size available in the row, then report
that no further blocks of the required size are available in the row and repeat the
booking menu.
3. If the user enters a ? the program should offer the customer every block of seats
of the required size in the whole theatre. This process should start from the first
row and proceed back a row at a time. For example, again using the partially
booked theatre shown above, if the user requested 9 seats, the program should
offer in turn:
Seats A1 to A9
Seats C1 to C9
Seats C2 to C10
Seats E3 to E11
Seats E4 to E12
If the customer selects a block of seats, then return to the main menu. If none are
selected, or there is no block of the required size available in the whole theatre,
then report that no further blocks of the required size are available and repeat the
booking menu.
4. If the user enters a # the program should display the current status of the seating
in the theatre, exactly the same as for the T option from the main menu and then
repeat the booking menu.
5. If the user enters a 0 (zero), the program should exit from the booking menu back
to the main menu. If for example the user wanted 9 seats and no block of 9 was
left in the theatre, he would need to make two separate smaller bookings.
The program should perform limited data validation in the booking process. If a single
character other than 0, ? and # is entered, it should be treated as a row letter and then tested
for falling within the range of valid rows, eg A to H in the example above. Any invalid row
letters should be rejected.
If more than one character is entered, the first character should be tested as a valid row letter,
and the numeric part should be tested for falling within the given row. You are NOT
required to test for valid numeric input as this would require the use of Exception handling.
You are provided with a class file:
Pad.java
containing methods that can be used for neat alignment of the seat identifiers in the theatre
plan.
File Processing
The file to be read must be opened within the program and if the named file does not exist, a
FileNotFoundException will be generated. It is desirable that this Exception be caught and
a corrected file name should be asked for.
This is not required for this assignment, as Exception handling has not been covered in this
Unit. It will be acceptable if the method simply throws IOException in its heading.
The only checking that is required is to make sure that the user does supply a file on the
command line, containing details of the performance. This can be tested for by checking the
length of the parameter array args. The array length should be 1. If not, display an error
message telling the user the correct way to run the program and then terminate the program
System.exit(0);
The file should be closed after reading is completed.
Program Requirements
You are expected to create at least three classes in developing a solution to this problem.
There should be an outer driving class, a class to represent the theatre performance and its
bookings and a class to represent a single row within the theatre.
You will also need to use arrays at two levels. You will need an array of Rows in the Theatre
class.
Each Row object will need an array of seats to keep track of which seats have been reserved.
Your outer driving class should be called BookingOffice and should be submitted in a file named BookingOffice.java
Your second, third and any additional classes, should be submitted in separate files, each
class in a .java file named with the same name as the class
I am also very sorry to give such a long description.but i mainly want to know how to approach for this program.
also how to designate each row about it's column while it is being read from the text file, how to store it, how to denote first row as row A(second row as row B and so on) and WHICH CLASS WILL PERFORM WHICH OPERATIONS.
pls do give a rough guideline about designing each class and it's reponsibilty.
thanking u and looking forward for your help,
sincerely
RK

yes i do know that........but can u ppl pls mention
atleast what classes shud i consider and what will be
the functions of each class?No, sorry. Maybe somebody else will, but in general, this is not a good question for this forum. It's too broad, and the question you're asking is an overall problem solving approach that you should be familiar with at this point.
These forums are best suited to more specific questions. "How do I approach this homework?" is not something that most people are willing or able to answer in a forum like this.

Access the adobe form pdf data in abap or java programs

Hi,
We created an adobe form, with few text boxes, and emailed to user for filing his data into the pdf file.
He filled the text boxes and saved the pdf, and sent back the pdf file by mail.
Now our requirement is:
we need to read the values entered by the user in pdf and update in certain ztables using abap or java.
case 1: using abap
How can abap program read the entries/values in pdf.
is there any doc/blog that shows how to access the adobe form data in abap.
do we need to use/install any software for this.
case 2: using java
Is it possible to read/retrive the adobe form data into java. once the data is into java program, i can utilise the data for several puposes.

using ABAP:
check the program: FP_PDF_TEST_03
This program reads the data from Adobe into XML format.
After this you have to read the data from XML format into ABAP(hope you know how to convert XML to ABAP or simply google it).
Thanks,
Chandra

Java parser for regular expression to java program

Hi All,
I am very new to parser technologies .I am looking for a (java)parser which can read the "regular expression" and can convert it into "java program".Please let me know is there any thing related to this.
Thanks in advance.
Your will be appriciate.
Regards,
Sai.

Hi Jos,
Thank you for your quick response .You're welcome.
If you have any sample code or simple example for how to use those
classes (Pattern,Match) ,will you please send me .It will be helpful for me.Jverd gave you two nice links already in his reply #3
If there is any "open source" for parsering regular expressions.
Please send me I am very new to parser technologies.Note that that Pattern class take care of all the parsing of REs, i.e. there's
nothing 'interesting' left for you to do any parsing whatsoever. Can you
elaborate a bit on what you exactly want to do and learn?
kind regards,
Jos

Convert Oracle Forms into Java (swing & JSP's)

Dear All,
We are currently in the process of evaluating our upgrade of system, which is using forms 4.5. One of the options we are considering at this stage is converting all forms into Java program. I am currently doing some pilot work on this project. I am using FormsWizard, a product of InformatikAtelier Gmbh, along with Forms 6i and Jdeveloper 9i. Has any one done this before in this group? Your assistance is much appreciated.

Grant, Thanks for that mail. It was very useful article. The article has lots of brilliant points consider. I may have to discuss with our System Architect. With my experience in both forms and Java, it is hard to justify the business benefit out of this conversion. We are a strong Oracle house and have no intention of moving towards J2EE at this stage.. Thanks once again.

Importing the Java API into basic programs

How do I import the API that comes with the JDK1.3 into my programs ? Is it a case of simply import java.api.*; ??
Does the new 1.3 version of the compiler include a Javabook which can be imported into programs. I have a text book which has sample programs which import Javabook. When I come to compile them, the compiler reports that Javabook is not known. Is Javabook from an earler version of the java compiler ?

It depends on what you want to do just as an example if you wanted to create a window app with a textfield you would need to import the necessary classes. Here is a sample of a JFrame with a text field:
import javax.swing.*;
import java.awt.*;
public class Frame1 extends JFrame
BorderLayout borderLayout1 = new BorderLayout();
JPanel jPanel1 = new JPanel();
JTextField jTextField1 = new JTextField();
public Frame1()
super();
try
jbInit();
catch (Exception e)
e.printStackTrace();
private void jbInit() throws Exception
this.getContentPane().setLayout(borderLayout1);
this.setSize(new Dimension(400, 300));
jTextField1.setText("jTextField1");
this.getContentPane().add(jPanel1, BorderLayout.CENTER);
jPanel1.add(jTextField1, null);
Note the import statements of java.awt.*; and javax.swing.*; this tells the compiler the to look for all the files needed to create this frame. The compiler already knows what it needs from the API, you just have to tell it where to look.
In short JavaBook should either come with the book on CD ROM or you have to download it from the publisher. Also check and see what files you need to import and use the import statement to point to the file that it needs: for example
import JavaBook.*;
Hope this helps

Unable to see the imported files in ODI after executing my java program

Hi,
I am using the following java code to import the physical topology into ODI11G.
===========================================================================
ImportServiceImpl importService =
new ImportServiceImpl(pOdiInstance);
importService.importTopologyFromFolder(importService.IMPORT_MODE_SYNONYM_INSERT_UPDATE,FolderPath, true);
===========================================================================
The above code went through fine while executing my program.But, i can't able to see the imported topology in ODI.
Can you suggest me how to import the topologies as well as work repository into ODI through Java programming.
Thanks in advance,
Ganesh Kesavarapu

I would do that as a last resort, as it happens to be a client server, I don't think they'd appreciate me needing to reboot a Unix server during the day. Would anyone have any other suggestions?
I just removed the JSPs from the live server, and refreshed the page and Tomcat could not find the JSPs, so I'm sure I have the correct directory. I then made sure the .java and .class files were deleted from the work directory, uploaded my new files (again) and hit refresh... and yet again I was served the same code as always, when I view source it still shows me the old source code even though the JSP file and compiled java files and class show that the new file should be shown, not the old one.
