About deprecated API
hello friends,
A friends of mine gave me the code of his project. After running it in
NetBeans 4.0, I get the following message:
NewStudentEntry.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Reason, that some of the methods have deprecated. How I could find these
deprecated methods?
thanks in advance

There must be a setting for compiler options somewhere in NetBeans.Indeed, there must. ;o)Hey, I don't use NetBeans. We have JBuilder, but it is way too slow (especially with the way our code works). 'vi' and command-line compilation/running on Unix is the way to go, anyway. I even just use jdb on the command line. It does the job.
When we first got Windows on our home computer, I hated it. I was used to the DOS commands for copying and renaming files. File Manager (and now Explorer)? Who needs it?! ;-) I'd rather type than use the mouse, any day. Always felt like I had more control, and knew more what I was doing, with the full DOS commands than with Windows File Manager.

If you don't type "javac", you must be using an IDE.
In your IDE there should be some kind of configuration
tab or option for "compiler options" or compilation options
or compiler arguments... something like that.
put "-deprecation" in that text box and recompile.
Your compiler should tell you all about which methods
are deprecated -- you then go to your trust JavaDocs
and lookup those methods in the API and read WHY they
are deprecated (i.e. OLD, outdated, defunct, no longer used)
and what you should use instead. Then, correct your
code to no longer use the deprecated methods and instead
do things as suggested in the deprecation comments. -
Having problems linking two java classes getting a "deprecated API" error??
Hi,
I am tryin to link one page to another in my program, however i get the followin msg:-
Project\alphaSound.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
Process completed.
this only happens when i add the bold piece of code to the class; even though the italic piece of code does take you to a new page?:-
public class alphaSound extends JPanel implements ActionListener
{static JFrame f = new JFrame("AlphaSound");
public alphaSound() {
public void actionPerformed(ActionEvent event) {
Object source = event.getSource();
else if(source == vowel)
{ Vowelm vm = new Vowelm();
vm.setSize(Toolkit.getDefaultToolkit().getScreenSize());
vm.show();
f.dispose();
else if(source == back)
{ MainPage main = new MainPage();
main.setSize(400,300);
main.show();
f.dispose();}
public static void main(String s[]) {
WindowListener l = new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
//JFrame f = new JFrame("AlphaSound");
f.addWindowListener(l);
f.getContentPane().add(new alphaSound());
f.setSize(Toolkit.getDefaultToolkit().getScreenSize());
f.show();
}here is the class its tryin to call
public class Vowelm extends JPanel implements ActionListener
{static JFrame v = new JFrame("VowelSound");
public Vowelm() {
..etc...
public static void main(String s[]) {
WindowListener l = new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
//JFrame f = new JFrame("VowelSound");
v.addWindowListener(l);
v.getContentPane().add(new VowelmSound());
v.setSize(Toolkit.getDefaultToolkit().getScreenSize());
v.show();
}Im pretty sure ther is some conflict between the two classes due to the way they are called and designed?
Hope you can help!
Kind Regards
RajYou may want to check your show() calls and see if
they can be replaced with setVisible(). Forexample,
in your Vowelm code, you have a static JFrame v.
At
the end of your main function, you use v.show().As
of JDK1.1, this has been deprecated in favour of
setVisible(boolean).hey show() in JFrame is from Window and in windowits
not deprecated ..
show is not decrecated thats for sure ... i dontknow
y you said that ...
you can look in docs as well..
True - but this in turn overrides show() from
java.awt.Component, which has been deprecated. My
guess is that's where the problem comes from.
Thanks for the Dukes!
FlicAnd then again - perhaps not. After looking into this a bit more, I take back my last comment about the Component override. However, as I said in my original reply, compiling with -deprecation should tell you which show() call is flagging the error. There is definitely one somewhere that the JVM doesn't like - without seeing your complete code, it's hard to say exactly where. Based on what you've posted, my guess is that it is within the Vowelm class.
Next time, I'll try to avoid 'shooting from the hip'.
Again, thanks for the Dukes,
Flic -
Where can I find all list for 'deprecated API' in upgrade Oracle 11.2.0.4 to 12c?
Dear all:
Thanks in advance for help! we are upgrading oracle 11.2.0.4 to 12c (most recent release). However, so far we have a diffculty in get & confirm a complete list of 'all deprecated API' for 12c upgrade; because we need to assess this before proceed to kick-off upgrade.
Our application is written in JAVA. The following API/parameters are recommended by others for assessment upgrade 12c impact:
OraclePreparedStatement.setExecuteBatch()
OraclePreparedStatement.getExecuteBatch()
OracleCallableStatement.setExecuteBatch()
getEndToEndMetrics
getEndToEndECIDSequenceNumber
setEndToEndMetrics
setApplicationContext
clearAllApplicationContext
Basically, which area we should look into: JDBC, Universal Connection Pool, webLogic server, or Oracle ODBC driver? to ensure application continuity after upgrade to 12c? I get this note today but it is for 'Java ALL API': https://docs.oracle.com/database/121/JAJDB/deprecated-list.html
Is there any metalinke Note you can refer to check? I'll check with application team about their code writting.
thank you very much!Hi Srini: sorry I wasn't able to get our applicaition full architect yet...-:((, I'm a new hire in the team, it is my 2nd week; so that's why I say 'thanks in advance to everyone' in my post. All I know is 'App is written by Java', and probably use JDBC/ODBC to connect to DB (and by which type of connection pooling mechanism I'm not sure).
We may also have WebLogic, or app interface with OBIEE/SAP tools.
Those parameters of 'OraclePreparedStatement.setExecuteBatch' was taken in URL in my post, I feel someone write as 'to-do' in checklist but may not fully understand it. At this moment to clarify further, we are worried if any changes like PL/SQL stored procedure, oracle library source code, API parameters that are changed in 12c from 11.2.0.4 (or 11gR2 in general) to affect the application? is there any metalink note can help us get more info about this?
Sure I'll consider open an SR for our case, any note is also welcome because nobody here has expertise knowledge for API impacted from upgrade 11.2.0.4 to 12c.
thank you very very much! -
JCo (in UDF) throws: "...uses or overrides a deprecated API."
Hi everybody,
when using JCO in UDF I get the error:
<b>MyMapping_.java uses or overrides a deprecated API. Note: Recompile with -deprecation for details. 1 error</b>
Does anybody know how to solve the problem?
The problem occurs only when I try to access the tableParameters:
<i> codes = function.getTableParameterList().getTable("COMPANYCODE_LIST");</i>
Regards MarioHi Mario,
With every latest Java version its APIs keep changing and some functions are removed or "deprecated", so if you are getting this error which means JRE you are using not have that function available so compile your code with Java -deprecation to suppress that error.
To check JRE version type Java - version on command prompt and then refer to Java API (also available online) to get detail about that particular function, otherwise you can also chose alternate function to achieve your programming objecting. I prefer if you see JCO API for help on this function.
Refer to sample code : http://www.sapdevelopment.co.uk/java/jco/jco_callfunc.htm

Show error overrides a deprecated API ?
hi,
when my java program run, it shows,
Note: D:\javaexample\myJavaPgm.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
what this error message.
Can I ignore this warning ?.
or how can i solve this warning?.hi,
when my java program run, it shows,
Note: D:\javaexample\myJavaPgm.java uses or overrides
a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
what this error message.
Can I ignore this warning ?.
or how can i solve this warning?.Deprecation means a method or class has been identified as obsolete. That means that there is a newer and better alternative to something you are doing. It also means that perhaps one day the deprecated thing will disappear from the API (unlikely probably but could happen).
To solve the warning you will have to find out what it's complaining about.
javac -deprecation myJavaPgm.javaWill tell you what exactly is the problem.
Then you can look in the API for alternatives. -
What's this mean? - "uses or overrides a deprecated API."
Hi, I'm a newbie at Java and I'm getting this error when I try to compile my program:
"Note: C:\MarsLander\NewUser.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details."
I haven't a clue what is going on here, can anybody help?Methods and classes may get deprecated with the threat that they will be removed form the API in a future version. Deprecated things can be but should not be used.
(Deprecated features can be undeprecated in a future version though. There are at least tow examples for this.)
As the message tells, compile it with the -deprecation flag and the compiler will report which method or class it is about. -
when i complied the following program, the complier said "Server3in1.java uses or overrides a deprecated API"
why??thanks!!!
import java.net.*;
public class Server3in1 {
public static byte buffer[]=new byte[1024];
public static void main(String args[]) throws Exception {
DatagramSocket ds=new DatagramSocket(1234);
while(true) {
DatagramPacket p=new DatagramPacket(buffer,buffer.length);
ds.receive(p);
System.out.println(new String(p.getData(),0,0,p.getLength()));
}To be more specific, the way the Original Poster is going about constructing strings will work differently in different countries. Since this is not what you want to happen (typically), the authors of the Java language have marked that way of doing things as "deprecated" - i.e., obsolete. The link has some suggestions about what to do instead.

AIR4 Mac store submission: Deprecated API
I just tried to submit my app to the Mac store (following the known steps).
Got this error back:
Deprecated API Usage - Apple no longer accepts submissions of apps that use QuickTime APIs.
I realize not many devs care about the Mac store, but are there any plans for a workaround?Well thats not good news at all
I really thought the QuickTime API rejection was part of the WebKit.dylib issue as I thought that was the verbage when I first failed to remove it, but Apple removes all Resolution Center messages from past binary submissions so I can't even check that.
Ironically Chris Campbell even recently asked for samples of MAS AIR apps:
http://forums.adobe.com/thread/1386194
What AIR SDK version are you using for this submittal and are you using any ANEs as part of the app?
I know the recent AIR 4 beta on labs is all about meeting Apple's new iOS XCode 5 February 1st requirements, but I wonder if there is anything in this update that also forces any new compatibility with the MAS as well.
Only other place QuickTime API rejections come up on a Google search is for somone using a third party developer framework:
https://forum.xojo.com/7307-submiting-to-mac-app-store-and-getting-quicktime-api-error/100
Otherwise this is a pretty serious problem if the raw Mac AIR runtimes are facing new rejection issues for the MAS, my existing app on the MAS isn't due for a new update just yet so I won't know myself for a little while whether this is a new change for MAS when I go to update it. -
I have tried (unsuccessfully) for hours and hours to correct a deprecated Api problem with an old java program I have been tinkering with. Is there anyone out there who may be able to help me? I would appreciate it very much.
Hello Lovadina,
I do not think my problem is the most difficult problem that has ever been posted but because I am so new to this I am having difficulty in fixing a java program I am working on. It is to do with an old API Mouse event that is currently part of the source code and from what I have read about it, it should not take much to update it as an old version is being used. You can contact me at [email protected] Thanks -

Since I installed the last JDK update, I get the same warning:
MyFrame.show(): Deprecated API, show() in java.awt.Window has been deprecated.
But I try to find in Sun site, and at the method description it's not deprecated yet...
Any idea? What should I use instead of MyFrame.show()?Yeah, that is, I'm a little sleepy yet...
If you want to know, java.awt.Window.show() should be replaced by Component.setVisible(true). -
compiling samp10.java
samp10.java:32: Note: The method java.net.URL createURL(java.lang.String) in class oracle.xml.sql.dml.OracleXMLSave has been deprecated.
URL url = sav.createURL(fileName);
^
Note: samp10.java uses a deprecated API. Please consult the documentation for a
better alternative.
2 warningsIgnore what I said. I misread the message. The createURL needs to be changed to getURL in samp10.
