but throws ClassCastException on the cast oracleSet......
i try withthis code:
ResultSet rs = ****query****
Blob b = rs.getBlob(1);
OutputStream out = b.setBinaryStream(1);
but throws java.sql.SQLException: Funzione non supportata
Why?????
what's can i do?

What is the diffrence between package javax.sql and java.sql

Is javax designed for J2EE?
And when to use package javax?

Hi,
What is the diffrence between package javax.sql and java.sql?The JDBC 2.0 & above API is comprised of two packages:
1.The java.sql package and
2.The javax.sql package.
java.sql provides features mostly related to client
side database functionalities where as the javax.sql
package, which adds server-side capabilities.
You automatically get both packages when you download the JavaTM 2 Platform, Standard Edition, Version 1.4 (J2SETM) or the JavaTM 2, Platform Enterprise Edition, Version 1.3 (J2EETM).
For further information on this please visit our website at http://java.sun.com/j2se/1.3/docs/guide/jdbc/index.html
Hope this helps.
Good Luck.

How to save image into blob:java.sql.SQLException: ORA-01465:nvalid hex

hi all,
I am trying to save an image (blob) into oracle. When i try this i am getting following error.

                      st.executeUpdate(sqlText);
                      con.commit();In the above Insert statement i tried with "blob" insted of "outstream" still same but when i try with the string "3s34se"
it is inserting into database..
I am new to blob can any one explain me why is like that.
Thanq in adv.

JBO-27122: SQL error & java.sql.SQLException: ORA-01843: not a valid month

Hi,
We developed OA page for Employee's Payslip and it is working fine for all the employees but it is not working for only one employee...Getting the error as
oracle.apps.fnd.framework.OAException: oracle.jbo.SQLStmtException: JBO-27122: SQL error during statement

## Detail 0 ##
java.sql.SQLException: ORA-01843: not a valid month
Real Scenario is:
The user "DANISH.LOTFY" is login into application and when he click on Payslip to the month then he is always getting the above error.
For testing purpose we have removed his employee assignment from user screen(fnd_user) and assigned some other employee name (say MOHAMED.ELBAHY)... After this when DANISH.LOTFY logins into the application and payslip page is working fine...(He can able to see MOHAMED.ELBAHY payslip.....
Realy we don't know this strange behaviour of OA ...

I'm using Netbean 6.7.1, Tomcat 6.0.18, JDK 5.0. And I already tried to put the sqljdbc.jar to the lib folder of Tomcat or the JAVA_HOME\jre\lib\ext but no luck.
Please give advice.

The issue is with your usage of the sql:setDataSource tag. You should either specify a driver and url attributes, or* a datasource attribute.
The datasource attribute follows the syntax: url[,[driver][,[user][,password]]] (ref Section 10.1.1 of the JSTL1.1 spec)
You were using the datasource attribute, but not including the driver within it.
So one of the following should work:
<sql:setDataSource driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" url="jdbc:microsoft:sqlserver://localhost:1433;databaseName=AdventureWorks;" user="sa" password="sa" var="dSource"/>or
<sql:setDataSource dataSource="jdbc:microsoft:sqlserver://localhost:1433;databaseName=AdventureWorks;,com.microsoft.sqlserver.jdbc.SQLServerDriver,sa,sa" var="dSource"/>----------
As an aside your code example doesn't seem to match with the error message:
In your code:
<sql:setDataSource driver="jdbc:sqlserver://localhost:1433;databaseName=AdventureWorks;user=sa;password=sa" var="dSource"/>From the error message:
<sql:setDataSource driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" dataSource="jdbc:microsoft:sqlserver://localhost:1433;databaseName=AdventureWorks;" user="sa" password="sa" var="dSource"/>These two are not the same. Not sure if that is caused by a forum bug, or you trying various things. But the fact they don't match doesn't help :-).

Importing oracle.sql.BLOB through SQL Loader

Hello,
Currently the system we have creates .sql files and executes them. This takes a long time, so we're attempting to change to using SQL Loader. The one problem I'm having that I can't seem to fix is finding out how to imitate the behavior of this SQL statement through SQL Loader:
INSERT INTO KRSB_QRTZ_BLOB_TRIGGERS (BLOB_DATA,TRIGGER_GROUP,TRIGGER_NAME)
VALUES (oracle.sql.BLOB@515263,'KCB-Delivery','PeriodicMessageProcessingTrigger')
I tried creating a lobfile and placing the text oracle.sql.BLOB@515263 within it this way
INTO TABLE KRSB_QRTZ_BLOB_TRIGGERS
WHEN tablename = 'KRSB_QRTZ_BLOB_TRIGGERS'
FIELDS TERMINATED BY ',' ENCLOSED BY '##'
TRAILING NULLCOLS
tablename FILLER POSITION(1),
TRIGGER_NAME CHAR(80),
TRIGGER_GROUP CHAR(80),
ext_fname FILLER,
BLOB_DATA LOBFILE(ext_fname) TERMINATED BY EOF
However, as expected, it merely loaded the text "oracle.sql.BLOB@515263" into the database. So does anyone have any ideas of how to imitate that insert statement through SQL Loader? The only information I have available is the string "oracle.sql.BLOB@515263", no other files or anything to aid with actually getting the binary data.
When the .sql file is run with that insert statement in it, a 1.2kb BLOB is inserted into the database versus a 22 byte BLOB that contains nothing useful when done through SQL Loader.
Alex

My preference is DBMS_LOB.LOADFROMFILE
http://www.morganslibrary.org/reference/dbms_lob.html
did you try it?

Java.sql.SQLException: Fail to convert between UTF8 and UCS2: failUTF8Conv

Hi all,
I am writing a servlet that connects to Oracle 8.0.6 through jdbc for jdk1.2 on NT 4.0
English version and it works fine.
But when the servlet is deployed to a solaris with Oracle 8.0.5 (not a typo, the oracle on
NT is 8.0.6 and oracle on solaris is 8.0.5) and jdbc for jdk1.2 (of course, for Solaris),
the servlet failed with the Exception:
java.sql.SQLException: Fail to convert between UTF8 and UCS2: failUTF8Conv
(I am using JRun 3.0 as the application and web server for both NT and Solaris)
(The database in both the NT and solaris platform are using UTF8 charset)
My servlet looks like this: (dbConn is a Connection object proved to be connected to Oracle
in previous segment of the same method):
String strSQL = "SELECT * FROM test";
try { Statement stmt = dbConn.createStatement();
ResultSet rs = stmt.execute(strSQL);
while (rs.next()) {
out.println("id = " + rs.getInt("id"));
System.out.println("id written");
out.println("name = " + rs.getString("name")); // <-- this is the line the
exception is thrown
System.out.println("name written");
} catch (java.sql.SQLException e) {
System.out.println("SQL Exception");
System.out.println(e);
The definition of the "test" table is:
create table test(
id number(10,0),
name varchar2(30));
There are about 10 rows exists in the table "test", in which all rows contains ONLY chinese
characters in the "name" field.
And when I view the System log, the string "id written" is shown EXACTLY ONCE and then there
is:
SQL Exception
java.sql.SQLException: Fail to convert between UTF8 and UCS2: failUTF8Conv
That means the resultset is fetch back from the database correctly. The problem arise only
during the getString("name") method.
Again, this problem only happens when the servlet is run on the solaris platform.
At first I would expect there are some strange code shown on the web page rather than having
an exception. I know that I should use getBytes to convert between different encodings, but
that's another story.
One more piece of information: When all the rows contains ascii characters in their "name"
field, the servlet works perfectly even in solaris.
If anyone knows why and how to tackle the problem please let me know. You can feel free to
send email to me at [email protected]
Many thanks,
Ben

Hi all,
For the problem I previously posted, I found that Oracle had had such bug filed before in Oracle 7.3.2 (something like that) and is classified to be NOT A BUG.
A further research leads me to the document of Oracle that the error message:
"java.sql.SQLException: Fail to convert between UTF8 and UCS2: failUTF8Conv"
is a JDBC driver error message of error number ORA-17037.
I'm still wondering why this behaviour will happen only in Solaris platform. The servlet on an NT machine I am using (which has an Oracle 8.0.6 and jdbc for jdk 1.2 running) is working just fine. I also suspect that this may be some sort of mistakes from jdbc driver.
Nevertheless, I have found a way to work around the problem that I cannot get non-English string from Oracle in Solaris and I would like to share it with you all here.
Before I go on, I found that there are many people out there on the web that encounter the same problem. (Some of which said s/he has been working on this problem for a month). As a result, if you find this way of working around the problem does help you, please tell those who have the same problem but don't know how to tackle. Thanks very much.
Here's the way I work it out. It's kinda simple, but it does work:
Instead of using:
String abc = rs.getString("SomeColumnContainsNonEnglishCharacters");
I used this:
String abc = new String(rs.getBytes("SomeColumnContainsNonEnglishCharacters"));
This will give you a string WITH YOUR DEFAULT CHARSET (or ENCODING) from your system.
If you want to convert the string read to some other encoding type, say Big5, you can do it like this:
String abc = new String(rs.getBytes("SomeColumneContainsNonEnglishCharacters"), "BIG5");
Again, it's simple, but it works.
Finally, if anyone knows why the fail to convert problem happens, please kindly let me know by leaving a word in [email protected]
Again, thanks to those of you who had tried to help me out.

Java.sql.SQLException: Error accessing jdbc driver

Hi,
We are using WebLogic Server 7.0 as Application Server.
We now create a connection pool named regPool and
a Tx datasource named regDS.
When we get the connection from the datasource, exception occurred.
java.sql.SQLException: Error accessing jdbc driver: driverURL =
jdbc:weblogic:pool:regPool, props = {enableTwoPhaseCommit=false,
jdbcTxDataSource=true, connectionPoolID=regPool}
at
weblogic.jdbc.jts.Driver.wrapAndThrowSQLException(Driver.java:323)
at weblogic.jdbc.jts.Driver.getNonTxConnection(Driver.java:377)
at weblogic.jdbc.jts.Driver.connect(Driver.java:129)
at
weblogic.jdbc.common.internal.RmiDataSource.getConnection(RmiDataSource.java
:265)
So I guess that why we can't use CMP for finding data. Here is the error when we call the finder.
javax.ejb.FinderException: Exception in findAllEmr while preparing or
executing statement: 'null'
java.sql.SQLException: Cannot obtain connection after 30 seconds. ,
Exception = Access not allowed
java.sql.SQLException: Cannot obtain connection after 30 seconds. ,
Exception = Access not allowed
at
weblogic.jdbc.jts.Connection.wrapAndThrowSQLException(Connection.java:694)
According to the exception message, it looks
like the connection fail between WLS and Oracle 9.2.
Here is a scenario I think you should need to know.
I change the table-name in the weblogic-cmp-rdbms-jar.xml
to a name that doesn't exist in the database.
Then, re-package the EJB, copy it to server and restart the server.
A exception occurred that says the table doesn't exist.
So, in this case, it looks like the datasource works and
connection is fine.
Any recommendation will be appreciated.

Datasource, POJO and java.sql.Blob

Hello,
is "java.sql.Blob" a valid type for a POJO datasource ?
I declared one but I just dit not succeed in rendering its jpg picture.
My java code is quite simple :
ReportClientDocument reportClientDocument = new ReportClientDocument ();
reportClientDocument.setReportAppServer(ReportClientDocument.inprocConnectionString);
reportClientDocument.open (REPORT_NAME, OpenReportOptions._openAsReadOnly);
// lBlob is a class which implements java.sql.Blob interface
LPOJOData [] dataP = {new LPOJOData(new lBlob("Picture.jpg"))};
POJOResultSetFactory factory = new POJOResultSetFactory(LPOJOData.class);
POJOResultSet resultSet = factory.createResultSet(dataP);
reportClientDocument.getDatabaseController().setDataSource(resultSet, "", "");
and my POJO class :
public class LPOJOData {
          private java.sql.Blob zimage;
          public LPOJOData(java.sql.Blob zp){
               this.zimage = zp;
          public java.sql.Blob getzimage(){
               return zimage;
The field "zimage" on the report is designed through a "field definition only" database, zimage is defined as a Blob field.
Any clues ?
Regards,
Serge

I have just found a list of the data types supported by a POJO Class :
# boolean
# byte
# char
# double
# float
# int
# short
# java.lang.Boolean
# java.lang.Byte
# java.lang.Double
# java.lang.Float
# java.lang.Integer
# java.lang.Short
# java.lang.String
# java.SQL.Date
# java.SQL.Time
Well, java.SQL.Blob is not one of them.
Is java.SQL_Blob will be a valid POJO type in the future ?
Is there another way than POJO to feed a report from an in-memory datasource ?

Java.sql.SQLException: [Microsoft][ODBC SQL Server Driver]Opti onal feature

in my project i wanted insert a date object to the database for that i am using PreparedStatement.setDate(fieldNum,dateObject), i tried out the code segmets and used the java.sql.date onject only but i am gettig the exception"java.sql.SQLException: [Microsoft][ODBC SQL Server Driver]Optional feature not implemented".see the code below which i used
String sql = "insert into debug (filing_date) values (?)";
PreparedStatement insertPS = dbConn.prepareStatement(sql);
String dateS = "2001-00-01"; //That's jan 1, 2001
java.sql.Date date = java.sql.Date.valueOf(dateS);
insertPS.setDate(1,date);
insertPS.executeUpdate();
@@@@@@@@@@@@ i tried using this way also to get into the real format "MMM d, yyy"but got the exceptoin this time also, the code is
MMM d, yyy format, which java.sql.Date doesn't accept: String dateIn = "January 1, 2001"; String formatIn = "MMM d, yyyy"; // format of incoming string
//parse the date using java.util.Date classes
ParsePosition pp = new ParsePosition(0);
SimpleDateFormat sdfi = new SimpleDateFormat(formatIn);
java.util.Date date = sdfi.parse(dateIn,pp);
if( date == null ) (throw new RuntimeException"Unparsable date: "+dateIn);
//convert a java.util.Date to a java.sql.Date
java.sql.Date sqlFromLong = new java.sql.Date(date.getTime());
//output is: 2001-01-01 System.out.println("sqlFromLong (java.sql.Date): "+sqlFromLong);
pls help me regardig this thanks in advance susanth

Java.sql.Date vs java.util.Date vs. java.util.Calendar

All I want to do is create a java.sql.Date subclass which has the Date(String) constructor, some checks for values and a few other additional methods and that avoids deprecation warnings/errors.
I am trying to write a wrapper for the java.sql.Date class that would allow a user to create a Date object using the methods:
Date date1 = new Date(2003, 10, 7);ORDate date2 = new Date("2003-10-07");I am creating classes that mimic MySQL (and eventually other databases) column types in order to allow for data checking since MySQL does not force checks or throw errors as, say, Oracle can be set up to do. All the types EXCEPT the Date, Datetime, Timestamp and Time types for MySQL map nicely to and from java.sql.* objects through wrappers of one sort or another.
Unfortunately, java.sql.Date, java.sql.Timestamp, java.sql.Time are not so friendly and very confusing.
One of my problems is that new java.sql.Date(int,int,int); and new java.util.Date(int,int,int); are both deprecated, so if I use them, I get deprecation warnings (errors) on compile.
Example:
public class Date extends java.sql.Date implements RangedColumn {
public static final String RANGE = "FROM '1000-01-01' to '8099-12-31'";
public static final String TYPE = "DATE";
   * Minimum date allowed by <strong>MySQL</strong>. NOTE: This is a MySQL
   * limitation. Java allows dates from '0000-01-01' while MySQL only supports
   * dates from '1000-01-01'.
public static final Date MIN_DATE = new Date(1000 + 1900,1,1);
   * Maximum date allowed by <strong>Java</strong>. NOTE: This is a Java limitation, not a MySQL
   * limitation. MySQL allows dates up to '9999-12-31' while Java only supports
   * dates to '8099-12-31'.
public static final Date MAX_DATE = new Date(8099 + 1900,12,31);
protected int _precision = 0;
private java.sql.Date _date = null;
public Date(int year, int month, int date) {
    // Deprecated, so I get deprecation warnings from the next line:
    super(year,month,date);
    if(! isWithinRange(this))
      throw new ValueOutOfRangeException((RangedColumn)this, "" + this);
public Date(String s) {
    super(0l);
    // Start Cut-and-paste from java.sql.Date.valueOf(String s)
    int year;
    int month;
    int day;
    int firstDash;
    int secondDash;
    if (s == null) throw new java.lang.IllegalArgumentException();
    firstDash = s.indexOf('-');
    secondDash = s.indexOf('-', firstDash+1);
    if ((firstDash > 0) & (secondDash > 0) & (secondDash < s.length()-1)) {
      year = Integer.parseInt(s.substring(0, firstDash)) - 1900;
      month = Integer.parseInt(s.substring(firstDash+1, secondDash)) - 1;
      day = Integer.parseInt(s.substring(secondDash+1));
    } else {
      throw new java.lang.IllegalArgumentException();
    // End Cut-and-paste from java.sql.Date.valueOf(String s)
    // Next three lines are deprecated, causing warnings.
    this.setYear(year);
    this.setMonth(month);
    this.setDate(day);
    if(! isWithinRange(this))
      throw new ValueOutOfRangeException((RangedColumn)this, "" + this);
public static boolean isWithinRange(Date date) {
    if(date.before(MIN_DATE))
      return false;
    if(date.after(MAX_DATE))
      return false;
    return true;
public String getRange() { return RANGE; }
public int getPrecision() { return _precision; }
public String getType() { return TYPE; }
}This works well, but it's deprecated. I don't see how I can use a java.util.Calendar object in stead without either essentially re-writing java.sql.Date almost entirely or losing the ability to be able to use java.sql.PreparedStatement.get[set]Date(int pos, java.sql.Date date);
So at this point, I am at a loss.
The deprecation documentation for constructor new Date(int,int,int)says "instead use the constructor Date(long date)", which I can't do unless I do a bunch of expensive String -> [Calendar/Date] -> Milliseconds conversions, and then I can't use "super()", so I'm back to re-writing the class again.
I can't use setters like java.sql.Date.setYear(int) or java.util.setMonth(int) because they are deprecated too: "replaced by Calendar.set(Calendar.DAY_OF_MONTH, int date)". Well GREAT, I can't go from a Date object to a Calendar object, so how am I supposed to use the "Calendar.set(...)" method!?!? From where I'm sitting, this whole Date deprecation thing seems like a step backward not forward, especially in the java.sql.* realm.
To prove my point, the non-deprecated method java.sql.Date.valueOf(String) USES the DEPRECATED constructor java.util.Date(int,int,int).
So, how do I create a java.sql.Date subclass which has the Date(String) constructor that avoids deprecation warnings/errors?
That's all I really want.
HELP!

I appreciate your help, but what I was hoping to accomplish was to have two constructors for my java.sql.Date subclass, one that took (int,int,int) and one that took ("yyyy-MM-dd"). From what I gather from your answers, you don't think it's possible. I would have to have a static instantiator method like:public static java.sql.Date createDate (int year, int month, int date) { ... } OR public static java.sql.Date createDate (String dateString) { ... }Is that correct?
If it is, I have to go back to the drawing board since it breaks my constructor paradigm for all of my 20 or so other MySQL column objects and, well, that's not acceptable, so I might just keep my deprecations for now.

Oracle.sql.BLOB array

Hi,
I have a database table(say MY_BLOB_TABLE.) having one blob column
I want to send each blob column as an attachment to a single email i.e. I for a particular case if I have 10 qualifying rows in MY_BLOB_TABLE,I want to send all these 10 blobs as different attachments with a SINGLE email.
I have the working code (from asktom) that allows me to send one attchment per email ..so I changed the code so that it takes array types to the things..
here is my code:
Database Type:
create or replace type xx_blobdata is varray(50) of blob;
create or replace type xx_attachedfile is varray(50) of varchar2(1000);
create or replace type xx_attachedfiletype is varray(50) of varchar2(1000);
Java Code
public class xx_attachments_mail
static String dftMime = "application/octet-stream";
static String dftName = "filename.dat";
public static oracle.sql.NUMBER
send(String from,
String to,
String cc,
String bcc,
String subject,
String body,
String SMTPHost,
oracle.sql.BLOB[] attachmentData,
String[] attachmentType,
String[] attachmentFileName);
PLSQL Wrapper
create or replace function xx_attachments_mail_send(
p_from in varchar2,
p_to in varchar2,
p_cc in varchar2,

java.lang.String,
java.lang.String,
java.lang.String,
oracle.sql.BLOB[],
java.lang.String[],
java.lang.String[]
) return oracle.sql.NUMBER';
Actual Call:
attachment_data :=xx_blobdata();
attachment_type :=xx_attachedfiletype();
attachment_name :=xx_attachedfile();
ret_code := xx_attachments_mail_send(
p_from => '[email protected]',
p_to => '[email protected]',

p_body => 'testing..',
p_smtp_host => 'myserver.com',
p_attachment_data => attachment_data,
p_attachment_type => attachment_type,
p_attachment_file_name => attachment_name);
Everything compiles. All objects are valid in database.But when I call I get the following error:
ORA-29531: no method send in class xx_attachments_mail
ORA-06512: at "XX_ATTACHMENTS_MAIL_SEND", line 1
Can anybody point out what is wrong that I am doing.
Thanks.

Its already there...
public static oracle.sql.NUMBER send();
The code works well if I remove arrays (i.e. []) ... my problem is the mapping or VARRAY to Java datatype...
I just read something on oracle.sql.array ....that is the solution for mapping Oracle VARRAY to Java data type... but still I dont have a working code...
Any help is highly appreciated...

Duplicate post:
Re: oracle.sql.BLOB array
Devang,
You asked:
Can anybody point out what is wrong that I am doing?Yes, I can.
VARRAY maps to "java.sql.Array" or "oracle.sql.ARRAY".
You can find more details in the JDBC Developer's Guide and Reference which is part of the Oracle documentation, as well as the JDBC sample code which can be accessed from here:

Good Luck,

Oracle.sql.BLOB ClassCastException

Hi everyone,
I'm trying to put a serialized Java object into Oracle. I am following the example here: http://www.oracle.com/oramag/oracle/01-may/o31asktom.html
Here is my code:
String sql = "begin " +
      "insert into rdm_logs (datetime, id, machine, ip_addr, action_code, tablename, comments, " +
     "row_before, row_after)" +
      "values (sysdate, ?, ?, ?, ?, ?, ?, empty_blob(), empty_blob()) " +
      "return row_before into ?; " +
"end;";
CallableStatement stmt = connection.prepareCall(sql);
stmt.setString(1, username);
stmt.setString(2, machine);
stmt.setString(3, ip);
stmt.setString(4, action_code);
stmt.setString(5, table);
stmt.setString(6, comment);
stmt.registerOutParameter(7, java.sql.Types.BLOB);
stmt.executeUpdate();
Object o = stmt.getBlob(7);
// output class name here
System.out.println(o.getClass().toString());
// cast to oracle.sql.BLOB
oracle.sql.BLOB blob = (BLOB) o;The system output is:
class oracle.sql.BLOB
java.lang.ClassCastException: oracle.sql.BLOB
As you can see, the System.out gives oracle.sql.BLOB as the object class type, so why does it throw an exception when I cast it to be the same?
Any help would be appreciated.

As you can see, the System.out gives oracle.sql.BLOB as the object
class type, so why does it throw an exception when I cast it to be the same?This can happen if the two BLOB classes have been loaded with two different unrelated class loaders. Even though the names of the classes are the same there are two separate classes.
How to fix this depends... Somehow arrange the JDBC driver to be loaded by the system class loader before any other class loader has a chance to load it?

(Again) java.util.Date vs java.sql.Date

Hi there,
(Again) Im trying to understand the EXACT difference between
java.util.Date vs java.sql.Date.
Googling, I can see that this is a very "popular" subject, but I still
cannot figure out it exactly.
Many writers claim that java.sql.Date only stores the DATE part (yyyy-
mm-dd) but not the TIME part (hh:MM:ss) of a Date/Time value, but that
I can easily disprove:
java.util.Date ud = new java.util.Date(); java.sql.Date sd = new java.sql.Date(ud.getTime()); System.out.println(DateFormatUtils. format(ud, "yyyy-MM-dd HH:mm:ss.SSS")); System.out.println(DateFormatUtils. format(sd, "yyyy-MM-dd HH:mm:ss.SSS"));
Output:
2009-09-18 15:17:36.635 2009-09-18 15:17:36.635
So, apparently, java.sql.Date and java.util.Date have THE SAME
precision (at least down to the millisecs...).
And the official API documentation, really looks more confusing than
helpful to me::
*"java.sql.Date:*
*A thin wrapper around a millisecond value that allows JDBC to identify*
*this as an SQL DATE value. A milliseconds value represents the*
*number of milliseconds that have passed since January 1, 1970*
*00:00:00.000 GMT.*
*To conform with the definition of SQL DATE, the millisecond values*
*wrapped by a java.sql.Date instance must be 'normalized' by setting*
*the hours, minutes, seconds, and milliseconds to zero in the*
*particular time zone with which the instance is associated. "*
Exactly what means "an SQL DATE value" ? How EXACTLY does it differ
from a java.util.Date value?
Most importantly: WHY does JDBC need to distinguish between them?
And, here again: *"a java.sql.Date instance must be 'normalized' by*
*setting the hours, minutes, seconds, and milliseconds to zero in the*
*particular time zone..."*
What does that mean exactly? Apparently, the constructor doesnt
enforce this restriction, per the example above. So what's the REAL
point with this type, java.sql.Date?
Very greatful, if you can help me clarify this, once and for all.
TIA,

And the official API documentation, really looks more confusing than helpful to me:The problem is that you need to understand SQL as well as Java for this to make sense. It's not the Java API's job to tell you how your SQL database works - there's a myriad of subtle differences even when the DB is compliant with the SQL spec.
Most compliant databases support DATE, TIME, and TIMESTAMP values. DATE represents only a date. TIME represents only a time. TIMESTAMP represents both. There are further complicating factors, but that's roughly how it stands.
In Java the normal type for representing time is (or was when the API was created) the java.util.Date but this is a close approximation only to the TIMESTAMP value. In order to bring the two together the java.sql.Date, java.sql.Time and java.sql.Timestamp classes were created. Making them derive from java.util.Date was probably not a good idea.
java.util.Date suffers from a number of deficiencies. java.util.Calendar was supposed to address them but didn't really succeed. The JodaTime library is rather better, but it's all a lot more complicated than you might expect - partly because time management really is a much harder problem than it appears at first glance - there are timezones, leap years, leap seconds, the difference between astronomical and atomic time, and so on and so forth.
