Printing directly from the bean class

i am using a 3 tier layer to implement an event calendar
i have a calendar.jsp that sends form data to eventday.jsp, which extracts the form data and calls mtds from eventBean.java that connects to db. my print statements are in the bean class. my prob is that the required information are not printed.
i have debugged calendar.jsp and eventday.jsp and am quite sure that both are ok. i have placed a simple print statement in the bean class n it does not get printed.
can i know if it's true we can't print directly from the bean class?
should i return the values to be printed in dayevent.jsp instead?

i see, then will it be okay if i store the value retrieved from the bean in a vector n retrieve the vector content in the jsp page? but i remember my tutor sayin that it's poor programing to expose the data structure to other classes or pages? wat other mtd can i use then? thks!

                              InputField ip= (InputField) myContext.getComponentForId("spoofCust");

Lohitha,
Try replacing your two lines of code:
InputField ip= (InputField) myContext.getComponentForId("spoofCust");
String spoofCust=ip.getValue().toString();
with:
InputField ip = (InputField) getComponentByName("spoofCust");
String spoofCust = ip.getValueAsDataType().toString();
Let me know how that works for you.

After a recent update of Photoshop CS6 (via Creative Cloud downloader) I cannot print directly from the program. A print error is shown in the printer document queue. I can print from all other programs including Illustrator. Any solutions to this proble

When I copy the Photoshop file to another computer with an old version of Photoshop (CS2) I can print OK from it

Nobody can help you. You have not provided any proper technical information like system info, what printer, what settings etc.. You need to do a lot better before people can even begin to guess and help you.

Interested in printing from the iPad iPhone with PST?

I'm pretty sure you can but others who use iOS will have to chime in here; I use Android. (And if others who are using Android are wondering: Yes, you can.)

Two sided printing directly from finder?

Hello all
I am having trouble with two-sided printing directly from the Finder on a shared printer over Airport.
I know that I can highlight a file in the finder, then hit CMD-P and it will print the document for me (opening up the program that created it - be it Pages or Word). I can select multiple files and print them this way.
What I *can't* do is get a two-sided document this way.
I have setup a preset for two-sided printing and set it as default. It doesn't matter what program created the document - it just won't duplex print. I have gone into CUPS and set the printer default as two-sided along the long edge.
My printer is a Brother HL-2240D, connected to an iMac running 10.6.8. I am attempting to print files from a Mac Pro (1,1) running 10.7.5, over my Airport network. I can print two-sided by opening the file in the word processor (Word or Pages) and using the Print dialogue, but I can't do it from the Finder.
Can anyone please help?

I forgot to add - I have set up a duplex preset on the iMac (server) as well. I'm not sure if that makes a difference or not...
thanks!

I can using AirPrint from safari and email to my hp printer but do not get print as an option from the pulldown menu from the new york times and other apps. How can I print directly from these apps?

I can't seem to print directly from apps like the new York times. Print is not an option from the pulldown menu. Print to my hp printer works fine from safari and email though and from some other apps. Do some apps not permit printing? That doesn't right.

Thats funny. If go to ny times on safari therebis a print icon and no problem printing. On the app -- and I am a paid subscriber -- no print option ...
You can ask the NY Times why not.
Standard behavior is that Airprint always works with iBooks, Mail, Photos, and Safari. Apps are up to their author.

This is a hint to anyone who cannot find their airprint printer from their ipad: after 10 hours of trying everything imaginable, i can now print directly from my iPad by turning off the bluetooth in settings and waiting for 30 seconds. presto!

after spending a full day and a half trying everything imaginable, i finally found a way to get my ipad to find my new airprint capable printer. I could print from email or the cloud, but not directly from my ipad. After reading a discussion about bluetooth printers, i turned off bluetooth in settings, waited 30 seconds, and voila!! I was able to print directly from my ipad. Try it if you are having troubles

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

How to print directly from Windows7 desktop on Officejet 5745 without emailing the printer

Successfully installed HP 5745 and set up eprint on Dell Ispiron 3847 running Windows 7 Professional. How do you print a document or email on desktop directly from the printer without emailing it to the printer's email?
Prior Windows XP printing by clicking mouse and selecting "print" from options list doesn't seem to work with Wndows 7.

Hi,
Given printer is connected to your wireless network already, you have to install its software and driver on your Windows 7 machine. Please download software and drivers from the following link:

Normally we have to print from an application. Which application does not allow you to print ?

How do I import an image directly from the internet without printing and scanning it in first?

How do I import an image directly from the internet without printing and scanning it in first?

You can also Ctrl click on the image, save the image to your desktop and open it in Photoshop.
1.
2.
3. Open in Photoshop by double-clicking on the saved image on your Desktop or Cmd o in Photoshop.
I don't see any point to copying and pasting from a browser into a new file in Photoshop.
If you want to put an image onto an already open image in Photoshop, use the File > Place... command and select your saved image.

I have problems printing with a HP Officejet 6500 printer directly from my iMac. The printer itself does function well, as I can print from another PC without any problems. Does anyone have a clue?

I have problems printing with a HP Officejet 6500 printer directly from my iMac. The printer itself does function well, as I can print from another PC without any problems. Does anyone have a clue?

Hello:
I must apologize . I should have checked here first:
http://support.apple.com/kb/HT3669#HP
According to the list, there is no driver for your printer included in OS X 10.7.
There are a couple of options:
1. Contact HP to see if they have a workaround.
2. If the model of printer is not listed but your printer is a PostScript printer or PCL Laser printer, try the "Generic PostScript" or "PCL Laser printer" drivers. Generic printer drivers may not let you access all the features of your printer.
I have not tried #2, but some people have had success.

How can I print directly from my iPad to my new Primax 3260 printer when I have no computer. Do I need a portable single unit Router?

How can I print directly from my iPad to my new Primax 3260 printer when I have no computer? Do I need a portable one to one Router for the wiFi connection. My Internet is through Telstra 3G system.

Is your printer a wifi printer or hard wired only? If it's a wifi printer then you might want to look into third party apps like Print n Share or Print Central which allow a version of air printing to non-air print printers.
You may also want to look on the manufacturer's site. Maybe they have a fix for you.
If your printer isn't wifi, then you will need a router to get it on a wifi network to print to it. As far as I know, there is no support for the iPad to do wired printing.
