How to Print Receipts to Miniprinter from Apex Application

I have an APEX Application to control orders in a restaurant. I need to automatically print orders to an Epson miniprinter in the kitchen as they are generated in multiple workstations within the place.
There is no way of doing this in APEX. Is there a way to do it using PL/SQL? The server is not inside the place. The connection may be made through SQL*Plus or SQL Developer.
I can see hundreds of places where the receipts are printed automatically (convenience stores, department stores, etc). I am sure most of them are using Oracle. How do they do that?
I have been stuck with this for weeks. I can't find information about it in the forums, nor in the user manuals.
Please help.
Francisco.

Hi Sven,
Thanks for the reply.
I have an order_detail table where every dish and beverage is recorded. Where the category is dish, there should be a process running concurrently that sends that line (or the lines accumulated in a time interval of 30 or 60 seconds) to the printer and then mark them as printed to avoid selecting them in the following run. No button and no human intervention.
I have an APEX screen that does the job nicely, displaying the pending items and with a checkbox to mark them as delivered. But my customers want the printed thing.
For the check I have a BI Publisher report that is opened with a button, then the PDF opens and then the cashier must send that PDF to the printer. Two or three clicks needed and it works. But that is not practical for the cook in the kitchen.
The other issue is that the server is not within the place. Currently I am working with a server in the UK, and my business is in Mexico. So there is no way to have a printer physically connected to the server. Everything should be done at the client side.
So do you think there could be a solution in this scenario? Is there some way to spool from SQL Developer or SQL*Plus to a txt file concurrently? That might be the answer.
Option 2: Assuming the customer might want to buy its own server. Could you tell me more about that apex_job that may help?
Regards,
Francisco

How can i remove JUNK TEXT from APEX

Hi ,
In our project Apex has integrated with oracle apps,every time we will open apex front end from oracle application(EBS).so we have two kinds of instances 1) development and other is production
every time we export the apex application from developement instance and import in production instance . after imported into production * we got JUNK TEXT like "TEXT:TEXT" in apex front end* so how can i remove JUNK TEXT from APEX
Apex 4.0.0.00.46 version
please somebody help on this issue
Help would be appreciated
Regards
Narender B

Hi,
It is not clear what you are seeing here. Also we don't know how you have integrated Apex with EBS. My guess is you have linked an Apex page to the EBS menu and when you click on the menu link you see the additional text on the Apex page.
You need to give details of how you have integrated Apex with EBS and where and when this additional text is being displayed for me to give you any help on this issue.

How to print out multilingual reports from the main report using Xliff temp

Hi all,
How to print out multilingual reports from the main report using Xliff temp?
When I want main report call subtemplate and finish xliff tranlation
<?for-each@section:INVOICE?><?end for-each?>
<?import:xdo://XXIH.XXNR_XXINVPRINT_SUB.en.FI/?>
<?start:body?><?call:Header?><?call:Line?><?call:Weights?><?call:Banks?><?end body?><?call:Footer?>
Prints out fine with Finnish translation
But if I want in main program to check what language is used e.g.
if trx_number = 142 call Finnish translation and if trx_number =144,
call English translation.
<?for-each@section:INVOICE?><?end for-each?>
<?if:TRX_NUMBER=’142’?>
<?import:xdo://XXIH.XXNR_XXINVPRINT_SUB.en.FI/?>
<?start:body?><?call:Header?><?call:Line?><?call:Weights?><?call:Banks?><?end body?><?call:Footer?>
<?end if?>
<?if: TRX_NUMBER=’144’?>

<?start:body?><?call:Header?><?call:Line?><?call:Weights?><?call:Banks?><?end body?><?call:Footer?>
<?end if?>
Prints out always in English and never the Finnish translation.
Program goes fine to if branch but does not print out Finnish
Does anybody know what could be wrong?

Calling shell script from apex application

Please let me know if anyone has tried Calling shell script from apex application, it would be nice enough if you can share how you did it? Thanks

Hi,
Requirements
* CREATE JOB (10g Rel.1)
* CREATE EXTERNAL JOB (10g Rel.2 / 11g)
* EXECUTE on dbms_scheduler (granted to public by default)
Since Oracle 10.2.0.2 the commands are executed as user nobody.
Code:
--Create a Program for dbms_scheduler
exec DBMS_SCHEDULER.create_program('RDS2008','EXECUTABLE','c:\ WINDOWS\system32\cmd.exe /c echo 0wned >> c:\rds3.txt',0,TRUE);
--Create, execute and delete a Job for dbms_scheduler
exec DBMS_SCHEDULER.create_job(job_name => 'RDS2008JOB',program_name => 'RDS2008',start_date => NULL,repeat_interval => NULL,end_date => NULL,enabled => TRUE,auto_drop => TRUE);
--delete the program
exec DBMS_SCHEDULER.drop_program(PROGRAM_NAME => 'RDS2008');
--Purge the logfile for dbms_scheduler
exec DBMS_SCHEDULER.PURGE_LOG;
This is one way as suggested by Trent.
We can also achieve as follows.

How to connect to Oracle database from webdynprojava application

Hi
How to connect to Oracle database from webdynprojava application. where can we provide the code to connect to database.?
Thank You.

Hi,
You need to create Java Bean model. The bean is a typical java bean with default constructor, getter and setter. You can have additional methods for query etc. The attributes in the class will be your model node and attributes.
However you need to configure the connection and create JNDI using visual administrator before writing the code.
You can also consider writing Session EJB with oracle and using them in WD.

Sys_context not working from APEX application / environment

I am struggling to retrieve a user-defined context value using sys_context(...) from APEX application / environment
I have created a global context to be used as a storage mechanism for log severity to be recorded.
CREATE OR REPLACE CONTEXT PA_LOGGER_CTX USING PA_LOGGER ACCESSED GLOBALLY;It is seeded through a function pa_logger.set_severity(1) within the package pa_logger through (excerpt):
dbms_session.set_context(c_ctx_context_label, c_ctx_severity_label, TO_CHAR(p_severity_in));
with:
c_ctx_context_label     CONSTANT NVARCHAR2(16) := 'PA_LOGGER_CTX';
c_ctx_severity_label    CONSTANT NVARCHAR2(8) := 'SEVERITY';
p_severity_in   IN PLS_INTEGERusing the following from sqlplus, other DB-tools, works as expected:
-- setting it
BEGIN
pa_logger.set_severity(2);
END;
-- displaying it
SELECT sys_context('PA_LOGGER_CTX', 'SEVERITY') FROM DUAL;returns 2
This works from different sessions, different users ... no problem.
Using it from within an APEX (accessed via embedded gateway/XE11.2 or OHS/11.2.0.2.0 ) application or even from the "SQL Commands" from the APEX Workspace returns a NULL value for :
SELECT sys_context('PA_LOGGER_CTX', 'SEVERITY') FROM DUAL;And
   SELECT value FROM GLOBAL_CONTEXT WHERE NAMESPACE='PA_LOGGER_CTX' and ATTRIBUTE = 'SEVERITY';returns the right value, which obviously defies the purpose of using the CONTEXT.
It is as well possible to set the CONTEXT to a different value, which is picked up outside APEX, but even so using sys_context does not work, always returning NULL
As a note aside: using sys_context with a standard CONTEXT, e.g. SELECT sys_context('USERENV', 'NLS_DATE_FORMAT') from DUAL works without any problems.
I guess I have a conceptual break somewhere. Does this have to do with the APEX user used, wrapping within the APEX environment, the way the context is defined ....
Any help is appreciated.
Many thanks,
- Thomas

Hi Rod,
Thanks for the time to answer. Meanwhile I found some more hints on the subject (Retrieve values from my own global context in Apex and I do now understand the concept.
I understand that I can even clear the specific CLIENT_IDENTIFIER by issuing a "dbms_session.clear_identifier()", which then subsequently works
Looking at the CLIENT_IDENTIFIER as set by APEX it is "<apex_login_user><apex_session>";
I understand it is set for every DISPLAY-SUBMIT it is reset by the APEX framework.
Hence it is not sufficient to set it for a user session; it needs to be changed for every display-submit. I can achieve this through application processes, but I am really reluctant to do so, because I do not know, if APEX relies on the CLIENT_IDENTIFIER to be set the way it is done. I suspect a purpose behind this, causing me problems elsewhere. I post this as a seprate question as this question has been answered.
On to your point about: Using a table variable. This is the way it works currently, but allegedly using the CONTEXT would give us for the logging configuration a performance gain of about 1 dimension..... but unfortunately other problems..
Thanks!

Hello. I just upgraded to Lion OS X 10.7.3. I was previously running 10.5.7 which included the ENTOURAGE application. how do I retrieve needed information from this application that no longer runs on this new system?

Hello. I just upgraded to Lion OS X 10.7.3. I was previously running 10.5.7 which included the ENTOURAGE application. how do I retrieve needed information from this application that no longer runs on this new system?

The file you'll be looking for that has most of what you're looking for - messages, address book, etc. is the Entourage Database. The verison of Microsoft Office I run (on Lion) is Office 2008. By default the Entourage Database for this verison is at user/Documents/Microsoft User Data/Office 2008 Identities/Main Identity/Database. That folder (Main Identitty) also has your rules, signatures, and such. You'll have to recover this file from whatever backup you have. If you have a different version of Entourage, the file location will be a little diffferent.
Good luck

The best place to ask your question is at the JSMS website, forum or mailing list since this is no error that directly comes from a class belonging to the core Java classes.

How to open file system file from Apex?

Hi,
Can someone help me to find how to open a pdf file e.g. test.pdf from apex when someone click on a button ABC?
The file is located in /C/
Thanks in advance
Dip

You can use the Onclick event and window.location to show the file when the user clicks a button.
<input type=button onClick="window.location= 'file:///C:/Documents%20and%20Settings/rchamarthi/Desktop/test.pdf' + document.form1.cmuds.value;" value="Open File">The actual location of the file is "C:/Documents and Settings/rchamarthi/Desktop/test.pdf"
Since the location is treated as a URL, remember that it should be URL encoded.
Hence all spaces should be replaced by '%20' (32 being the ASCII for space and 20 in hex -> 32).

Does anyone know how to print a text message from a bill?

Does anyone know how to print text messages from a phone bill or view them?

There might third party apps or iTunes or iCloud options to backup the text messages from the Apple phone itself. Then you can print the contents of the messages from the backup.
There are similar applications for Android devices as well.

How to access a url only from APEX

Hi all.
We have a system that is accesible from internet, We are trying to secure the access to this system via login from APEX in order to deny the access to the URL if the request is not from our APEX app.
We configured the corresponding hostname in our APEX server and some firewall rules, but when a client clicks the link the hostname is looked in the client's computer, so is never found.
Is there any way to make this hostname resolution in the server's side?
Thanks in advance, regards.

sKC,
You may need to explain yourself in more detail
"How do I access a URL only from APEX?"
If you are trying to limit access to "mynormal.server.com" by seeing if the end user clicked on a link from "myapex.server.com", the answer is:
You don't.
Trying to limit access to a web page based on how you got there is a really really bad form of security due to the false sense of security it implies.
It is so bad that it is better to not even try.
reason:
All URL requests can be easily manipulated by the client computer that is making the request. (ie the request is easily faked.)
The Unix utility wget can be used to fake the 'referrer' information.

How to print out a date from the past

I am trying to print out a date from the past but I cant seem to get It,
Lets use for example Independece Day,
How would you write the code in order to print out that exact date?

Look at the
[url=http://java.sun.com/javase/6/docs/api/index.html?
java/util/Date.html]Date APIActually the Calendar class would be better to use, since you can set all the different fields from year to second, plus things like day of week, day of month, week of year, etc.
too slow
