Desperate, help please Servlet.service() for servlet jsp threw exception
Hi,
I have completed 99.99% of project development, when I am about to deploy JSC throws "Servlet.service() for servlet jsp threw exception javax.faces.el.EvaluationException: java.lang.NullPointerException" I can't understand why.
My application was working absolutely fine, I can't understand why its throwing exception now.
I tried debuging, but i can't understand where exactly its throwing exception and whats the error.
I would really appreciate your help, I have spent almost a day trying to figure out but din't get anywhere.
here is my server.log

hi,
I just found that this exception is thrown from function
public UIViewRoot createView(FacesContext context, String viewId) {
UIViewRoot viewRoot = handler.createView(context, viewId);
context.getExternalContext().getRequestMap().put(CREATED_VIEW, viewId);
setupPageBean(context, viewRoot);

in viewHandlerImpl.java.
Has anyone got ideas about this???
Any help will be greatly appreciated.

HELP -- please --- Temp Files for Microsoft Word
Please HELP -
I believe I overwrote separate file with that of an older working document. Is there a way I could find different versions of this document either in a TEMP file or some other way. I am at the brink of crying. Need to go see my boss soon and have to tell her the bad news.Don't reboot... Here is what I found for a PC...
Re: retrieving previous versions of word files?
yes you can, IF you haven't rebooted etc. Did exactly that for my son the other day. Had accidentally wiped out all his homework. Found the .tmp hidden files in the same folder, renamed them to .doc, and was able to open and retrieve most of his work. I assume your hidden files are viewable? -
HELP PLEASE, NOKIA TUNE FOR 3310
Hi. I have a Nokia 3310, and i want to compose the ringtone from movie Crank, that special Nokia Tune. can someone help me please ?
Sorry, I can't. I have tried to google it for quite a while but not found it. I don't think I will spend my sunday evening trying to figure out how to make that song.
From the youtube video, it sounds like the start out note is somwhere around a C#, but I don't think we are talking the standard A 440 mhz... tuning.. Though that's not the most important part. The intervals will define the tune. It sounds like some of the notes are in between. So if your 3310 can only make "clear" notes with a half step movement, I don't think it's possible make it sound good.
Then you might just start out with a random note and try out notes below from that point.
Good luck! -
Help Please Download links for flash lite wont work.
For Some reason the download links on on the adobe site dont
seem to be working. If possible can someone please email me the
install for windows mobile 5. Im going to be using it on a Motorola
Q.
Thanks allot guys, appreciate it.
[email protected]This is super weird, particularly because the ActiveX (for Internet Explorer), NPAPI (for Firefox) and PPAPI (for Chrome) browsers are all pretty different. This is definitely not the normal pattern.
Does *any* Flash content work? Maybe something old like http://www.homestarrunner.com? My guess is that it doesn't.
I definitely need some more clues:
- Operating System and Version
- Browsers and Versions
- Any anti-virus/anti-malware/firewall/save-flash-video-to-disk kind of stuff installed?
- Any JavaScript blockers or privacy plug-ins that might block JavaScript from executing?
My gut feel says reboot, Uninstall Flash Player | Windows, then download a fresh copy of Flash Player for Firefox and Internet Explorer by using each browser to go to http://get.adobe.com/flashplayer.
Hopefully that helps. -
Help please with exporting for print
Hi All,
Hopefully someone here can help. I have the opportunity to get some 24x30 inch lustre prints printed out for free but the printer has some specific file requirements which I am not 100% sure how to meet.
Here they are:
1. Colour space : Adobe RGB(1998)
2. File size must be 24x30"
3. Resolution : 300ppi
4. File : Level 12 (or lower) Photoshop JPEG
Questions:
1. I have calibrated my monitor with a ColorVision Spyder so I use that profile on my MBP monitor. I then usually export from Aperture using colorsync profile sRGB IEC61966-2.1. To meet the requirement above do I just need to change the colorsync profile on export to Adobe RGB(1998) or should I be doing something while editing?
2. I use a Nikon D70 so my files are 3024 x 1998, how do this translate to inches? Do I need to up size the files and if so how do I do this in Aperture?
3. I take it all I have to do here is change the DPI setting on export to 300 (is DPI the same as PPI?)
4. I think this just means the image quality will be set to 12 on export.
Sorry for all the questions but getting prints done at a lab is something new to me and I would like to try and get the best results.
Thanks in advance,
AndrewHi Ian,
Thanks heaps for your quick reply. In regards to your answer for the 2nd question:
"2. You definitely need to upsize the files, 24x30" at 300ppi is 7200x9000px. You can use the 'fit within' option and give a size in inches and it will upsize as needed on export. Note that 24x30 is a drastically different aspect ratio than your 3:2 dSLR shots, so you may also want to crop the images to the 5:4 aspect."
Can you please advise what size, in pixels, I would need to crop to plus will this make the image less sharp, therefore I should sharpen more? Sorry I have never up sized and printed an image before so not sure if there is a correct way of doing it (I think I read somewhere you should up size in increments of 10% or something?)
Cheers. -
Help Please, Battling Problem For Months
This is the first time I've posted on SunJava's forum, and hope I'm doing this right ^^; Please do correct me if I'm wrong.
For months, I haven't been able to compose mail on web-based email, view sites programmed in Java, or use Angelfire or Geocities or other similar programs. I've installed the Windows XP Service Pack 2 and attempted to Reinstall IE6, but was unsuccessful and go an error message. I've installed SunJava and enabled it under Internet Options' Advanced Tab. I've searched the web, Google and Forums pertaining to the topic, but haven't found anything that has worked. Any advice? Thanks! Greatly, GREATLY appreciated.I'm not really sure if any of the sites you mention actually use Java. Hotmail, for example, does not use Java. Most do use JavaScript though, which is something entirely different and is not a Sun product.
This isn't really the right place for questions like this. Although most people probably won't mind posts such as this, the forum is intended for use by people developing software using Java.
You might want to check out http://www.java.com/ instead. That's the official resource for 'consumers' (i.e. people NOT interested in writing programs using java, but only in using the programs themselves). There will probably be some facility there for reporting bugs or answering questions.
As a last resort, you might want to try using another browser. For example, take a look at the products at http://www.mozilla.org/ A lot of people actually prefer those browsers to IE for numerous reasons, including better security -

Need Help Please - PSD InDesign (for print)?
Hello Everyone,
I'm a graphic designer for a company that has decided to run some print ads in a magazine. At the time, I only had Photoshop to create their advertisement with. Now they have purchased CS4, which will make my life easier in the future, however, for now I have the problem of creating my advertisement made with Photoshop and creating a print ready PDF.
Here is my problem:
- I created a PSD at 8.5" x 11" at 300ppi
- I did not take in to account for the 0.125" bleeds and 1/8" trim
- It needs to be SWOP compliant (I figured out I can export a PDF that adheres to SWOP)
- Fonts should be Type 1 Postscript, no TTF (I'm using Helvetica and Arial, when I export the PDF, it says the embedded fonts are TTF)
- I'm totally lost with regards for designing work for print!
Here the specs they gave me, AFTER I created the design in Photoshop
====
Full page, full bleed 8.0" 10-3/4" (**I created my PSD as a 8.5" x 11" - without regard to bleeds**)
Include 1/8 bleed over all to ensure full page bleed
and keep live copy 1/4 from trim and crop marks.
CMYK, 4-color process printing only.
Do not add bleed to partial page ads.
All requirements are based on Specifications for Web Offset
Publications (SWOP). Any deviation from these specifications may
result in less-desirable printed results.
We support PDF files generated by Adobe Acrobat using
the X-1A Job Option Settings for Distiller. In order for
prepress to generate printable PDF s, it is important that
the native file is prepared accordingly.
Preparing native files for printable PDF s:
All images/scans must be in CMYK mode,
300 dpi resolution
Use Postscript (Type 1) fonts only. No True
Type, Windows/PC or custom fonts accepted
Embed all fonts
Do not nest EPS files in other EPS files
Four-color solids should not exceed SWOP
density of 280%
Provide two digital color proofs at 100% size, created
from the supplied digital file, on a contract-quality,
digital halftone proofing system in accordance with
SWOP web coated standards (AGFAPressmatch,
Kodak Approval, DuPont Waterproof, etc.). Laser or
inkjet proofs are not considered accurate in color and
are supplied for content confirmation only.
If supplied, the publisher is not responsible for color variances
between the digital file and final color reproduction.
NOTE: If proofs are not supplied, make-goods due to
reproduction quality will not be honored.
====
I've never done print work before, as I'm mainly a graphic designer for the web.
Any help on this matter would be greatly appreciated! Unfortunately for me, they bought the advertisement space with the magazine for the running of the next issue before speaking with me. So I'm under extreme pressure to get this underway. I'll be most grateful for any help or guidance, Thanks guys!
- DYou can Place a PSD in Indesign, but unless the bleed is a single color,
it's going to be easier to add bleed in Photoshop. Bleed is whatever
gets cut off when they trim the paper. Trim is close, but not exact, so
whatever picture or color goes to the edge of the paper must extend
beyond the edge to avoid trim including some white when the trim is not
quite perfect. If it's a picture that goes to the edge, you need to
figure out a way to extend the picture beyond the edge. If it's white
that goes to the edge, then you don't need bleed. If it's a non-tone
color field (a single color) then you could Place the PSD in Indesign
and add bleed color behind it and extending beyond the edge of the page.
The magazine should not concern themselves with TT or T1 fonts, either
one should work. That said, Helvetica and Arial are very close. If your
Helvetica is Type 1, just use Helvetica for the whole thing. If you
embed it in the PDF, it should show there as a Type 1 subset.

Servlet.service() Error. java.lang.OutOfMemoryError: Java heap space
Hi All,
I would be very grateful if you would draw some light for this error I got from running a online database connected image viewer (applet).
The application is quite simple, applet connect to servlet, servlet send 3 SQL statements to MySQL and retrieve image info (Strings) and 50 Files (- JPEG image) from a online database, and then pass all of data to applet from servlet. The size of total of images is around 3.5 MB, and I've increased JVM memory to 128 MB by using code "-xmx128m".
? Do I need send images from servlet to applet individually rather than push them in one go
? Is there memory leak in my codes
