Implementing database records through Trees

I am having a problem regarding trees.. Can anyone send me the code ,how to implement records from the Database through trees.. i m using JDBC. Please let me know soon .. and send me the syntax aswell..
Bye.. Thankssss

Since I am using CMP Entity Beans, I would like to use CMP/BMP facilities to delete
the Entity EJB instances (perhaps database rows) instead of taking a different
approach just for deletion.
Thanks anyway for your response.

Perhaps a stateless session bean that does some jdbc to remove the records?
You could
call it from anywhere, servlet, client side, entity bean....
With some sql something like:
"delete from table where column = criteria"

How to remove database records?
I know one solution which is to find the records by EJB finder methodand call
remove() in each entity bean instace.
Is there any other way to remove the records, for example I want toremove a bunch
of records based on a criteria in one shot.
Thanks in advance for your suggestion.

IPhone: Database records that reference a variable

Hello All,
Firstly let me say that I am a total newbie to the iPhone and mac programming in general so please be gentle on me.
An application I am working on pulls a bunch of dialogue text out of a database and I would like to have a person's name (whenever its used in the database records) reference a variable so i can change it easily everywhere its said.
For instance consider the database record: "Hello there BOB, how are you doing?" (just one of many such statements involving bob). I'd like to easily change this (and all other dialogues) to: "Hello there JAMES, how are you doing?
is there a way to put some special string in the database records so that they reference a global variable or some such? In keeping with the above; something like "Hello there @testName, how are you doing?
Thanks.

Thanks for the speedy reply. I think I understand the basics of string formating:
for instance NSString *greeting = [[NSString alloc] initWithFormat:@"Hi there, %@!",
nameString];
means (if i'm correct) a variable called greeting is of the type NSStrin and is assigned the value of "hello [whatever is in the value of some other string called namestring]".
My question is can we have code like this right in a database record...or is that problematic?
Again I am very new to this all so please forgive my ignorance. I don't even know how to setup/access a sql database on the iPhone. I'm reading through the docs...but its quite a lot of stuff to take in. Thanks.

Paging database records

Hi all
Can anyone send a complete code for implementing paging database records in jsp file
Thx

I agree, you shouldn't expect anyone to write your code for you.
If you want to see a sample of paging database records, see http://www.dotjonline.com/taglib/grid.jsp
Good luck.

OSB: Implementing database locks

Hi
Tools: OSB11g, Oracle DB 11g, IntalioBPM
I have a BS_BankProcessing business service which has "InsertBalance", "RetrieveBalance" and "UpdateBalance" operations. This BS is based on Account_Table in database.
I created a proxy service - PS_BankProcessing which forwards requests to BS_BankProcessing.
Then I invoked BPM process set for execution who are exposed to PS_BankProcessing. Around 100 process instances created and all accessed PS_BankProcessing for the same account number. As a result in database I could find several inconsistencies owed to simultaneous updation of DB by more than one BPM instance at the same time.
That means simultaneous BPM instance requests were processed by OSB.
How can I implement database locks in OSB or make PS_BankProcessing as a single instance proxy service so that there will be no conflicts in databasae updation?
T&R
Swapnil Kharwadkar

well what I did was a real quick fix. Its not elegant but this is the way I did it.
1. I created a workmanager in weblogic. Then I set its Max Threads Constraint=1. The same reference I gave in PS_BankProcessing. I am halfway through tests but this should make my PS_BankProcessing as singleton.
2. Then I created DVM for JNDI name and my sql queries. These I extract at runtime in message flow and execute through xquery. It makes solution somewhat loose-coupled. At later stage I could change queries without changing code.
But as Mr. Pierluigi said, it would be ideal to implement locks formally. I will try out that subsequently.

6Controling recording through "What you hear",

Dear community, Breif question, Is there any way to control what i record through "what you hear"?
Im using "Creative MediaSource 5" to record. I'm recording a radio show through Internet Explorer 8, and its two hours long. I've turned off windows sounds, but if i play a game, or video it will record that sound aswell through "what you hear", obviously which i do not want. I feel restricted on my computer while recording and don't think i should be with a product from top developer like creative. I found small fix by using windows 7's sound mixer and turning down volume on all other open apps but it would be ncie to implenet this into a seperate "what you hear" mixer recording. If you know of any third party apps i would be much obliged if not don't you think this would be something to implement in the future?
Thanks for taking the time to read my issue and hope you can solve my answer and look forward to your comments.
Regards
Revs

Problem resolved. Follow Creatives FAQ advice on uninstalling the Soundblaster device drivers...it's on this web site. Follow all the steps, but include deleting "Creative" out of the registry. This worked for me. I can not guarantee this on any other users machines. I'm assuming that the drivers get's damaged.
Good luck.

Update database record from email link or attachment ?

Hello,
Is there any way to send email from application with a link to update database record (like oracle workflow in selfservice).
This is applied for approval process.
Rather than the approval will log onto the application, he will click on the attachment or link then the update statement will fire.
Is it possible?

You didn't add a forms version, so this is hard to guess. If you are on 10g and higher then you are using Oracle Application Server; in the installation there is the mod_plsql apache module included as well:
http://docs.oracle.com/cd/B14099_19/web.1012/b14010/concept.htm
so you could simply call a stored procedure via a HTTP request which updates your record. If you are on a lower version of forms you could make use of the free mod_owa module which you could configure with a plain apache installation on e.g. your database server: https://oss.oracle.com/projects/mod_owa/dist/documentation/modowa.htm
you should implement some sort of authentication as well; both mod_owa and mod_plsql also have the facility to do so via +owa_custom+
OWA_CUSTOM
(see the OwaAuth directive in mod_owa for example).
Of course you could do the very same via a custom Java Servlet; however you'd have to implement the database connection pool, the call of your stored procedure, the authentication e.g. as well which you would get for free with the apache modules.

Saving database records in a flat file

I am trying to save data from relational database into a flat file and then read back records based on the certain criteria.
What will be a good approach for me? Should I use random access files or sequential files for storing and
retrieving data or is there some other technique that is more efficient that I can use.
Thanks

I don't think that reading database records from a flat file based on certain criteria is a good approach, no matter how you produce the flat file. Using a second database table makes more sense to me, especially since you already have database software available and ready for use.
(You asked about a "good approach" and then you wanted a technique that was "more efficient". Those two aren't the same thing at all.)

I can record midi data from my Mason & Hamlin Piano Disc Pro Record through my MOTU Traveller into Logic but Logic won't send midi data out to the MOTU Traveller to the Piano Disc player

Hello All,
I can record midi data from my Mason & Hamlin Piano Disc Pro Record through my MOTU Traveller into Logic Pro 9.1.8 but Logic won't send the midi data back out to the MOTU Traveller and thus to the Piano Disc player. I got it to playback one time but have no idea how and when it did it was looping or something because the velocity was way high coming back in and the damper pedal was slamming down. When I play a key on the piano the midi "in" light on the Traveller lights up. When I play the track back on my computer no lights blink on the Traveller and when I did the apple midi studio test in utilities when I play a key I get the confirmation signal noise and the Traveller blinks when I click on the down arrow of the Traveller in the Apple midi studio test the midi out light on the traveller never lights and the signal light on the piano does not blink either. No outbound signal at all...
I have messed with every possible parameter I can find and and have had help from one of Piano Disc's premier editors but no luck. The piano was prepped for me on Logic so it would work with my studio. I'm positive it's my fault and I'm overlooking something really simple and stupid but what!??!
Somebody please help. Thank you all in advance for ANY ideas you might have!

Blues Piano,
I'm not sure if this will be a help or not. I'm so Logic Pro wet behind the ears that I make newbies look experienced. However, I'm not expecting many on the Apple support forums have a PianoDisc system, much less one with the new optical record strip. While I don't have any record strip on my PianoDisc, I do have a PianoDisc iQ that's only a month old. I've been playing converted paper scrolls from hundred year old player pianos through it via the MIDI in port of the PianoDisc CPU. I've found I have to open the MIDI file in Logic Pro (10.0.4) then go to <Track><New External MIDI Track> then copy the existing track to that new external track. Only then can I see in the Track inspector (defaults left side of screen with the Icon for the instrument) the "Port" parameter. Then I can select my external MIDI device in that Port selector.
I've also encountered problems with the PianoDisc not using enough force on the notes or using too much force. To get around this problem, until I understand Logic better, I've been setting minimum and maximum volicities. To do that I right click on the track and select "Select All." Then I right click again and select "MIDI" then "MIDI Transform" then "Velocity Limiter." In the resulting pop up window in the center is a drop down and you can play with the velocity from "MIN" to "MAX" along with "ADD" "SUBTRACT" etc.
I hope this helps. I envy you your Mason & Hamlin. If you need more help on this just email me at pfleischmann at mac dot com.

Let me be sure I understand what you need. You want to connect an audio device to the Audio In port of your MBP and record its output with the MBP.
If that's correct, what you need is audio editing software. You can use GarageBand, which probably came bundled with your MBP, but it's a bit heavy for that purpose alone. A better tool is the free audio editor Audacity. It's powerful and cross-platform, which means that it's a little rougher around the edges than is usually the case with Mac software, but you can't beat the price. There are others (Sound Studio, Amadeus Pro, TwistedWave, Wave Editor, and more), but you can get going with Audacity.

Some fields are missing while recording through shdb

Dear Abapers,
I am doing bdc for F-27 t.code.Some fields,cobl-gsber(business area),cobl-kostl(Cost center) are missing while recording through SHDB.But when do it manualy the fields are displaying.Also i have ddded those fields manualy in the program,stll the fields are not getting captured.May anyone pls help me,why this problem is happening?What is the solution for this.
Thanks in Advance.

hi
i can tell u that few transactions wont suffice us with BDC,so for such transactions we do bdc with similar kind of transactions.
ie., The transactions FB60 and f-63 both are meant for Parking.
But we cant do bdc for FB60 Parking. So we do bdc for f-63.
similarly when we do bdc for vendor few fields wont appear...in that case, we use bapi for it....
So try to find an appropriate bapi or similar tcode which will suffice ur need
hope its clear.

Convert the Database records to a standard XML file format?

Hai,
i want to convert the Database records to a standard XML file
format which includes the schema name, table name, field name
and field value. i am using Oracle 8.1.7. Is there any option
please help me
Thanks in advance.

You could put the files somewhere and I can export them as QuickTime. Or you could find anyone you know who has Director. Or do the 30 day trial download
Another approach would be to play the DCR in a browser window, and do a screen recording. But that’s unlikely to give the perfect frame rate that you would get by exporting from Director.

Using Java Bean in JSP to show database record

I have links in my Tomcat container that if someone clicks on a specific link it should go to a Record page (Show.jsp) with all the values associated with a record from a database.
For example if someone clicks on a specific link like this:
LinkExample
it would take you to a jsp with database info for someone named Jones and show you his info:
Lastname = Jones
Firstname = Mike
City = San Diego
I would like to do this using a Java helper class and bean so I dont have any database connection or Java code in my JSP.
I created Java class file that has Database connection that works with a Java bean. I just dont know how to get the Show.jsp to work with the Java Bean and Java helper class file.
Here is what I have for Show.jsp and this is the part I have been working on the longest but cant get it to work because it doesnt seem to work with the database:<jsp:useBean id="user" class="num.UserDB"/>
//do I call getUser(lastname) here and if so how?
<jsp:setProperty name="user" property="*"/>
Last Name: <jsp:getProperty name="user" property="lastname"/><BR>
First Name: <jsp:getProperty name="user" property="firstname"/><BR>
City: <jsp:getProperty name="user" property="city"/><BR>My Java Helper class that compiles and connects to database:
package num;
import java.io.*;
import java.sql.*;
import java.util.*;
import num.User;
public class UserDB
public User getUser(String lastname)
User user = new User();
        try
     Class.forName...//database connection stuff here
    ResultSet results = stmt.executeQuery("SELECT * from user where lastname = '" + lastname + "'");
     if(results.next() == true)
     results.next();
     user.setLastname(results.getString("lastname"));
     user.setFirstname(results.getString("firstname"));
        user.setFirstname(results.getString("city"));
     catch(Exception e)
               System.out.println("Exception...");
   return user;
}My Java Bean that compiles here:
package num;
public class User
private String firstname;
private String lastname;
private String city;
public User()
     //no arg constructor
public User(String firstname, String lastname, String city)
       this.lastname = lastname;
          this.firstname = firstname;
          this.city = city;
public String getLastname()
          return lastname;
public void setLastname(String lastname)
     this.lastname = lastname;
//more bean methods for all fields here

Sorry if I wasnt specific enough. I have a link that passes a value (field that is passed is called lastname) to a JSP where I want to show record info for that value that is passed.
My question is how do I show the database record info on Show.jsp for the lastname field value of Jones where I want to use a Java Bean and Database helper class in Show.jsp
Here is the message I get when I hit the link (LinkExample) and it goes to Show.jsp:
org.apache.jasper.JasperException: Cannot find any information on property 'lastname' in a bean of type 'num.UserDB'

     if(results.next() == true)
     results.next();

     user.setFirstname(results.getString("firstname"));
                     user.city(results.getString("city"));
