Can I use ' ', ' ', '= ' and ' =' with java.sql.Timestamp objects in EJB-QL

ie. Is this valid?
<query>
<description>Find data between dates</description>
<query-method>
<method-name>findMetricsByDate</method-name>
<method-params>
<method-param>java.sql.Timestamp</method-param>
</method-params>
<method-params>
<method-param>java.sql.Timestamp</method-param>
</method-params>
</query-method>
<result-type-mapping>Local</result-type-mapping>
<ejb-ql>
SELECT OBJECT (o) FROM MetricResults AS o WHERE MetricResults.date > ?1 AND MetricResults.date < ?2
</ejb-ql>
</query>

No. Not with current EJB 2.0 CMP specs at least. Later revisions are supposed to fix this, but for now, this seriously limits the usefulness of EJB-QL.

Ejb-ql and java.sql.Timestamp object

Hi, I have a mySql database table that has a column containing a Timestamp object. I need a finder method for my ejb's that will allow me to query the table for rows between certain dates.
In other words, I need to query for entries that have a Timestamp object between 2 specified dates.
One solution is to change the column type from Timestamp to long (date in milliseconds). That way I can use the BETWEEN clause to search between 2 longs. I would rather not do that. Does anyone know of a way that I can search between 2 Timestamp objects?

You can use the SQL BETWEEN clause with dates, just use it like this:
WHERE OrderDate BETWEEN '1998/5/1' AND '1998/5/31'

Can not create WebService with java.util.Locale object why?

I am unable to create a WebService which contains a Locale Object in the request. I assume its because the java.util.Locale object is not Serializable. Can anyone tell me if there is a work around for this?

Hi,
Make sure your strings for Locale follow these rules...
The language string should be lower-case, two-letter codes as defined by ISO-639.
http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt
The country string should be upper-case, two-letter codes as defined by ISO-3166.
http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html
Or try with some constant Locales like
Locale.CANADA
Locale.US

Usage of java.sql.Timestamp with classes12.zip and ojdbc14.jar ?

Hi all,
If i'm using java.sql.Timestamp with classes12 it is functioning perfectly,
if i'm using ojdbc14 and java.sql.Timestamp it is functioning in different way and failing to do the action..
Example : update set xxx=yy where time = my Timestamp object set in Prepared statement
Hope to see the answer

http://forum.java.sun.com/thread.jspa?threadID=460615&messageID=2116517
Timestamp insert problem
Using the "classes12.zip" file that comes with the distribution for Oracle versions 8.1.6.x and 8.1.7.x, Oracle's DATE datatype is mapped to the "java.sql.Timestamp" class. However, the "ojdbc14.jar" driver maps DATE to "java.sql.Date", and "java.sql.Date" only holds a date (without a time), whereas "java.sql.Timestamp" holds both a date and a time.

Java.sql.Timestamp creation with value -4712.01.01 (oracle min timestamp)

How can I create ajava.sql.Timestamp with the value -4712.01.01?
Trying Timestamp timestamp = new Timestamp( -210863523208000l );leads to the date 4713-02-08 00:06:32.0.
Or what is the minimal java.sql.timestamp value in Java?

Yes it is 1st January 4712 BC.
Timestamp timestamp = new Timestamp( -4712, 1, 1, 0, 0, 0, 000 );//deprecated Method
System.out.println( timestamp ); // returns 2813-02-01 00:00:00.0
System.out.println( timestamp.getTime() );// returns -150904688400000Thats not what I want.You have lost me then. Unless of course you want to use SimpleDateFormat with an appropriate TZ to parse the date to a java.util.Date and then construct a java.sql.Timestamp from the java.util.Date using the java.util.Date#getTime() method to construct the java.sql.Timestamp .

A silly question about oracle.sql.timestamp and java.sql.timestamp

Hi,
I'm looking at a method that takes objects of type Object and does stuff if the object is really a java.sql.timestamp. If it is not then an error is flagged. In my case it flags an error when an object of type oracle.sql.timestamp is passed to it. Not really entirely comfortable with java (i'm still learning it), here's my stupid question :- why isn't oracle.sql.timestamp a subclass of java.sql.timestamp? Also in various books it indicates that java.sql.timestamp maps to oracle.sql.timestamp. Does that mean you have to physically do the mapping:
i.e.
java.sql.Timestamp t = new Timestamp( new oracle.sql.Timestamp( CURRENTTIMESTAMP ).timestampValue() );
or is there something else to it.
Thanks.
Harold.

The best forum for this is probably Forum Home » Java » SQLJ/JDBC
Presumably you are refering to oracle.sql.TIMESTAMP. While this is intended to (and does) correspond to java.sql.Timestamp it can't be a subclass because it needs to be a subclass of oracle.sql.Datum.

EJBQL, MIN and java.sql.Timestamp

I am trying to create a new finder method for a cmp bean which returns me the date of the oldest bean available.
the ejbql query looks like this:
select MIN (a.receiveDate) from AssetSchema as a
receiveDate is defined as a java.sql.Timestamp field in the bean. I am getting the following error:
Bean: Asset
Method: clover.AssetLocal findOldestDeleted()
EJBQL: select MIN (a.receiveDate) from AssetSchema as a
Error: JDO75334: Invalid type 'java.sql.Timestamp' of select clause expression for finder method.
anything wrong with the query or .....

Instead of using a finder, use an ejbSelect method. You can then use the aggregate function MIN. Wrap the ejbSelect in a home method.
In remote Home interface, define home method:
public java.lang.String selectMinSingle() throws RemoteException;
define the ejbSelect method in EJB class:
public abstract java.lang.String ejbSelectMinSingle() throws FinderException;
The ejbSelect is wrapped in a ejbHome method:
public java.lang.String ejbHomeSelectMinSingle()
try {
String s = ejbSelectMinSingle();
return s;
} catch(Exception e) {
throw new EJBException("ejbHomeSelectMinSingle: " + e);
Call home method from client:
String s1 = beanHome.selectMinSingle();
Not sure if this is what you're looking to do.
There is also the ORDER BY clause; i.e.,
<ejb-ql>Select p.quantity from ProductBean p ORDER BY p.quantity</ejb-ql>
use the ASC or DESC keyword:
<ejb-ql>Select p.quantity from ProductBean p ORDER BY p.quantity ASC</ejb-ql>
For finder:
query>
<description></description>
<query-method>
<method-name>findProductsByHighestQuantity</method-name>
<method-params />
</query-method>
<ejb-ql>Select DISTINCT OBJECT(p) From ProductBean p ORDER BY p.quantity DESC</ejb-ql>

RQL Error - JQuery Datepicker and java.sql.Timestamp

Hello everyone,
I am using JQuery Datepicker to select start and end date range.
Both start date and end date are successfully passed as like this. 10/01/2013 and 10/31/2013
It has java.sql.Timestamp mapping in both startDate and endDate.
Property name in component browser is transactionTimestamp.
It gives me following error when i passed both parameters.

    <dsp:param name="itemDescriptor" value="inStorePaymentStatus" />

can anyone suggest me a solution.
Thanks

Hi all,
Found the solution. We have to use parameter converter tools as well. that is the additional parameter called "date" where we passed date format.
<dsp:param name="startDate" param="10/12/2012" date="MM/dd/yyyy"/>
<dsp:param name="endDate" param="10/12/2015" date="MM/dd/yyyy"/>

How can I use LCCS with ActionScript 3 and Flash CS4?

Hi,
Using Stratus I was able to create an an application using Action Script 3 and Flash CS4. The sample code on the Adobe site was quite straight forward and easy to understand. I now want to switch over to LCCS but can't find anything any where on how to use Action Script 3 and Flash CS4 with LCCS. Do I need to know Flex to be able to use LCCS? Everything was quite simple and easy to understand with Stratus and makes complete sense. But LCCS is really confusing. Is there any sample code on how to establish a connection in Action Script 3 and then stream from a webcam to a client. There is nothing in the LCCS SDK that covers Flash and Action Script 3. Please help! I found the link below on some forum but it takes me nowhere.

Subject: How can I use LCCS with ActionScript 3 and Flash CS4?
Hi,
Welcome to the LCCS world.
Please refer to the SDK's sampleApps folder. There would be an app called FlashUserList. The app demonstrates how LCCS can be used with Flash CS4. Its a pretty basic app, but should help you moving.
We are trying to improve our efforts to help developers in understanding our samples. Please do let us know if we can add something that would help others.
Thanks

Call Apple's online store's telesales agents: 1-800-MY-APPLE (1-800-692-7753) or Customer Service and Sales Support at 1-800-676-2775. For Lion you'll get a redemptions code via e-mail and need to DL from the Mac Apple Store (requires SL 10.6.6+).

Java.sql.Timestamp and the Epoch

Hello all
according to the JavaDoc for Timestamp, the long parameter of the constructor represents "milliseconds since January 1, 1970, 00:00:00 GMT". However, running
class Main
public static void main (String [] args)
System.out.println (new java.sql.Timestamp (0l));
} produces 1970-01-01 01:00:00.0, which is 3.6 million ms since the time stated in the doc.
My box is set to GMT. Does anyone know of an explanation for this?
Cheers

I'd say that extra hour is the daylight savings hour.
The GMT timezone uses it, but UTC ( Universal time coordinates ) doesn't.

Owen

Hello Khayalh,
You should be able to link your phone number by following the steps in the article below. From your iPhone, sign out of FaceTime and iMessage and then sign back in and it should link. Check in the Start Conversation With and I Can Be Reached at section in iMessage and FaceTime respectively.

No you won't necessarily lose your photos when upgrading but it's very very unwise not to back up first. Backing up is like using a seat belt in a car. You can drive without one for years and have no issues, but if you do have a problem the outcome will be a lot worse. So, too, with back ups. And upgrading is one of those times when the risks of a problem are higher.
Most Simple Back Up:
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex: Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically.
Example of such apps: Chronosync - but there are many others. Search on MacUpdate or the App Store
