Java Programming Guidance requested

Hi guys,
Hey could you guide me on getting started to java programming on a fast track.
i have got very familiar with all the concepts and fundamentls of the language but still dont feel confident.Can any one suggest me where i can have sample codes or small sample demonstration projects which uses classes,interfaces,abstract classes and all the other fundamentls of java ie super(), this, static, final etc.In this way i guess i can understand the concepts better.Also at initial level which are the packages that need to be surfed mostly and mostly used.
Can any one guide me in this direction

How to submit a HTTP Request from a Java Program

I am working on an web based application where in I need to submit the HttpRequest through a Java Program and not through browser. Moreover my intent is just to submit the HttpRequest. I donot want to wait for the response to come back. I have used the URL Connection class to do the same and I am trying to post this request. The contents of the methods that I am using are as below:-
public void doPost(URL url, String inputXMLString) throws IOException
          //Create URLConnection based on the passed URL
          URLConnection connection = url.openConnection();
          connection.setDoOutput(true);
          connection.setDoInput(false);
          connection.setUseCaches(false);
          connection.setAllowUserInteraction(false);
          connection.setRequestProperty("Content-type", "application/x-www-form-
urlencoded");
          //Get the Connection's output stream and write the request to it.
          PrintWriter out = new PrintWriter(connection.getOutputStream());
          out.print("&ena-request-input=" + URLEncoder.encode(inputXMLString));
          out.flush();
          out.close();
Call to the above method does not invoke the URL I am intending to submit the request at.
Can anybody give me the clue....................................................?

I agree with the advice to launch a new thread to read and ignore the response. I don't think you should have to do it to make it work, but it's worth trying for two reasons:
1) If it turns out it does make it work, well, then either you can leave it that way, or use that as a clue to help figure out how to make it work the way you want.
2) There may be an error message there that will give you an idea why it's not working.
When you say it's not invoking the servlet, what does that mean, and how do you know? Is it just that the final results aren't being seen? Put a bunch of logging statements in the servlet. It could be that it's getting hit, but you're corrupting the string you're building, or sending some extra junk that it can't handle. Spit out a log statement from the start of doPost, to see if it's even getting there. Then log the parameter. Enclose the output in quotes or braces or something to make sure there's not extra junk. I've had XML docs not parse because there was a blank line at the beginning.
If it works in the browser but not from your standalone app, then you need to have the servlet tell what difference it sees in the two cases. Print out headers, other params, everything you can think of.
Re-read the docs for URL, HttpURL, whatever, to make sure you're doing all the right steps in the right order. Make a servlet that just takes a single, simple param=value via POST and see if you can get that to work.

Requesting an overview of how to call a Java program from EBS.

Hi,
I am an experienced Java developer in the middle of an implementation of EBS 12g. I am very new to EBS and I'm not sure where to start on this. I need to provide users the ability to call a Java program that prints a report from EBS. I would be grateful if somebody would outline the general approach that should be used. Links to documentation/tutorials are appreciated also.
Thanks,
Mike

Hi,
I need to provide users the ability to call a Java program that prints a report from EBS. Are you referring to Java concurrent programs? If yes, please see the documents referenced in this thread.

Java Program Using Threads

Hi there, im really new and have just started programming in Java, i have to create a java program which implement threads. Thread.Wait, thread.start them etc.
Here is the problem, any guidance would be great cheers guys
The manager of a company employs 3 secretaries who are of varying ability, but who all work extremely fast. Secretary A is the most experienced secretary and is capable of typing up a letter once every second. Secretary B is less experienced and is capable of typing up a letter once every 2 seconds. Secretary C is the junior secretary and is capable of typing up a letter once every 4 seconds. When a secretary has typed up a letter he leaves it in the manager?s tray for him to remove and sign. The manager removes and signs a letter from the tray once every 2 seconds. The tray can hold a maximum of 5 letters at a time. The tray?s limited capacity sometimes causes the various workers to be delayed. For example, if the tray is full after a letter has been typed, the secretaries must wait until the manager makes a space available before they can add another letter to the tray. Similarly, the manager must wait for at least one letter to appear in the tray before he can take it out and sign it.
In your program, make use of threads to represent each of the workers (the 3 secretaries and the manager), so that they can work in parallel. You will also need to declare a tray object, and ensure that all communication is properly synchronised to avoid indeterminacy and deadlock. While an office worker is busy typing a letter or signing it, you should send that thread to sleep for the appropriate time period. This can be achieved with a call to:
Thread.sleep(m);
where m is the number of milliseconds for which the thread should suspend.
The output from your program should take the form of a running commentary on the activity taking place in the office. An extract from it might look something like this (though it is up to you how you word this):
Secretary A is ready to type a letter
Secretary A has typed a letter, number now typed = 6
Tray full. Secretary must wait until a letter has been removed before adding another
Secretary C has typed a letter, number now typed = 2
Tray full. Secretary must wait until a letter has been removed before adding another
A letter has been removed from the tray. Tray = 4
The Manager has taken a letter from the tray to sign, number signed = 4
The Manager is ready to sign a letter
etc
Run your simulation until the secretaries have typed and filed 7 letters each, and the manager has removed and signed all 21 letters.
Thanks again

Then you're probably better off enlisting one-on-one, in-person help from your instructor, a classmate, or a private tutor, or joining a study group. Forums like this are not well-suited to tutoring you from the ground up.
If you're doing multithreaded homework and you don't even know where to start, it sounds like ether the instructor is horrible or you're in over your head, or you just haven't been keeping up with the class.
Good luck.

Hello,
Part of the HS_ERR_PID says:
# Java VM: Java HotSpot(TM) Server VM (1.6.0_01-b06 mixed mode)
Does that mean you are running CF8 without updater1 applied? If updater1 was there I would expect JVM 1.6.0_04. Give that is correct you could apply updater1 and once that is done even update the JVM to a more current version. I see Java Dev Kit 1.6.0_23 is current, I have successfully used CF8 with 1.6.0_22.
There might be some interesting detail in the coldfusion-out.log file which likely is in [CF]\runtime\logs or [Jrun]\logs pending server or multiserver.
HTH, Carl.

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.

How to remotly run a Java Program on machine B from machine A.

Hi all,
I would like to start a JVM/java program from machine A onto machine B (windows plateform). Machine B could be running at another location so where in the lan/intranet.
OR
I would like to be able to start the process(GUI application) on machine B using code running on machine A.
Has anybody ever done somthing like this? Any help will be greatly appreciated.
Kind regards,
Suleman.

Machine B would have to be "listening" for program requests from Machine A.
So, on machine B you could have
a) corba server
b) rmi server
c) program listening on a socket for messages
d) servlet running on a web server

Is there any way to close an IE browser on XP through a Java Program

Hi All,
I am working on an application which has a web form with various feilds in it, on selecting the fields and clicking submit, the form will launch a WinRunner application in a remote machine and runs a test. For this I am using Tomcat webserver (V4.0.1). Now the problem I have is, when I submit the form, and WinRunner Launches on the remote machine (which has Operating System XP), should not already have any Browser windows open on it. So, to ensure that no browser windows are open, Initially in my Java Program I want to write a code which cleans up all the OPEN Browser windows on that machine.
Can any one help me out in finding a way of closing the IE browser windows on a XP machine through a Java program. (There is a servlet in the Tomcat webserver which launches the application based on the browser request). Tomcat is installed on the machine where WinRunner will be launched, So my browser request goes to that machine directly.
Thank you very much,
Ramesh Babu M.V.

You can call some program (via Runtime.exec) that kills all IEXPLORE.EXE processes (ugly but could work for you). For instance, there is a program called kill.exe that you can try getting somewhere. My version of KILL.EXE is really old and somewhat buggy (killed all IEXPLORE.EXE processes but one in my Windows 2003 machine), so try checking if there's some newer version anywhere.

Calling servlet from a java program

Hi
I need to call a servlet's doPost() method from a java program. I have a specific situation, where I need to call servlet from a java program. DUring this call I need to pass a file and two string to the servlet. Servelt after receiving the file and string uploads the file to the server at a specified location. I am stuck up as how to call servlet from a java program instead of a HTML or JSP.
Can anyone help me to start with this.
any suggestion is welcome.

You have to establish a URLConnection with servlet from your java program.
URL servletURL = new URL("http://localhost:8080/Myservlet?str1=abc&str2=def");
URLConnection servletConnection = servletURL.openConnection();you can get the objectOutputStream
ObjectOutputStream oos = new ObjectOutputStream (servletConnection.getOutputStream());
oos.writeObject(your file object);-------------------------------------------------
In the servlet u can get the strings using request.getParameter("str1");
In the servlet u can get the strings using request.getParameter("str2");
file = new ObjectInputStream (request.getInputStream()).readObject()a lot of resources are available on this ...
hope this helps :)

Want to access RESTful Services through Java Program

We are trying to access RESTful Services exposed by Oracle database cloud through our Java code, with authentication enabled for a particular user.
Till now, we have completed below steps:
1) We have a working account with Oracle database cloud (Username – xxx.xxx)
2) We log in using the credentials for above account, and navigate to Oracle Apex ? SQL Workshop ? RESTful Services
3) We create a new “RESTful Service Module” by filling out the details as below:
     Name:                                  SampleTest
     URI Prefix:                            test
     URI Template:                       /getallemp
     Pagination Size:                    25 (kept to default)
     Required Privilege:                 TestGroupPrivilege
     Resource Handler Details:
                Method:              GET
                Source Type:      Query
                Format:               JSON
                Source:               select * from emp
After creating the above module and testing it, it works fine and the data is retrieved in JSON successfully.
The resulting URL for above RESTful Service Module is: https://<HOST_URL>/apex/test/getallemp
Note that “TestGroupPrivilege” is a privilege assigned to the user group “RESTful Services” and the user “xxx.xxx” is a member of “RESTful Services” user group.
4) We are unable to call the RESTful services from Java program. We are passing username and password in request header as basic authentication. But, we are getting: Error 500--Internal Server Error
5) If we change the “Required Privilege” to default i.e. no privileges present on the module, we can get the response through Java code and everything works perfectly fine.
Please suggest us in: How to access RESTful Services through Java code by passing user credentials in HTTP header for authentication. Also let us know if we have to do any settings through Apex, in case we are missing any.
Message was edited by: NeerajGirolkar
- When we are logging in to Oracle cloud on browser and execute the Oracle cloud RESTful service in another tab of same browser, we are able to get the result. But when executed the same RESTful service from a different browser or java program we get internal server error.
- After investigation, we found that when user logs in to oracle database cloud, a cookie is set in browser with name s “OAMAuthnCookie_cstest-domo.db.us1.oraclecloudapps.com:443” and value as some random token. This cookie is passed in the subsequent requests to the RESTful Service calls when using same browser and as a result, we are able to get the results
- In the Java program, we copied the same cookie with random token in the HTTP Request header and we got the proper response from REST APIs.
- It seems that this cookie is created by an Oracle Middleware tool/server called as OAM – Oracle Accounts Manager, which sends the authentication token after successful authentication and creates the cookie.
- We found that the cookie that OAM creates on authentication is exactly in the same format i.e. ‘OAMAuthnCookie_cstest-domo.db.us1.oraclecloudapps.com:443’. So, we are guessing that Oracle cloud uses OAM for authentication. Please refer to following link for same : http://docs.oracle.com/cd/E14571_01/doc.1111/e15478/sso.htm
Can anyone please suggest:
1.     How to provide authentication to Oracle Cloud REST APIs from java program?
2.     How to pass the username and password in Java code to OAM (or how to communicate with OAM using Java) so that we can receive the unique token from OAM. We can use the token in the further requests? 3.     Also in Oracle cloud white papers , it is mentioned that they support OAuth2.0. But we didn’t find any URLs for same. Can anyone please confirm?
Thanks
~ Neeraj Girolkar

Hi Nilesh,
We tried to connect to Oracle Cloud Database using the way you suggested above, but unfortunately it is not working as well.
Can you let us know the authentication process with Oracle Cloud Database? We found in documentation that it uses OAM (Oracle Access Manager) for authentication. Can you tell us a bit about that? That will be extremely helpful.
Thanks,
- Neeraj

I use the sdoapi.jar, sdomn.jar and sdoutl.jar stored in the jlib directory of the oracle installation path.
When I performe this query : SELECT BLOB, NUM_INODES, NUM_ENODES, NUM_ILINKS, NUM_ELINKS, NUM_INLINKS, NUM_OUTLINKS, USER_DATA_INCLUDED FROM ROUTING.ITA_SPAZIO_P_BLOBS_TABLE WHERE PARTITION_ID = ? AND LINK_LEVEL = ? [1181,1]
I got the following result
BLOB NUM_INODES NUM_ENODES NUM_ILINKS NUM_ELINKS NUM_INLINKS NUM_OUTLINKS USER_DATA_INCLUDED
(BLOB) 3408 116 3733 136 130 128 N

At first I create a two link level network with this command
exec sdo_net.spatial_partition('ITALIA_SPAZIO', 'ITA_SPAZIO_P_TABLE', 5000, 'LOAD_DIR', 'sdlod_part.log', 'w', 1);
exec sdo_net.spatial_partition('ITALIA_SPAZIO', 'ITA_SPAZIO_P_TABLE', 60000, 'LOAD_DIR', 'sdlod_part.log', 'w', 2);
exec sdo_net.generate_partition_blobs('ITALIA_SPAZIO', 1, 'ITA_SPAZIO_P_BLOBS_TABLE', true, true, 'LOAD_DIR', 'sdlod_part_blob.log', 'w', false, true);
exec sdo_net.generate_partition_blobs('ITALIA_SPAZIO', 2, 'ITA_SPAZIO_P_BLOBS_TABLE', true, true, 'LOAD_DIR', 'sdlod_part_blob.log', 'w', false, true);
Then I try with a single level network but I got the same error.
Please can samebody help me?

I find the solution to this problem.
In the LODConfig.xml file I have:
<readPartitionFromBlob>true</readPartitionFromBlob>
               <partitionBlobTranslator>oracle.spatial.network.lod.PartitionBlobTranslator11g</partitionBlobTranslator>
but when I change it to
<readPartitionFromBlob>true</readPartitionFromBlob>
               <partitionBlobTranslator>oracle.spatial.network.lod.PartitionBlobTranslator11gR2</partitionBlobTranslator>
The application starts without the obove mentioned error.
