Having trouble to call my EJB object

Hi All:
I used JDeveloper 2 to deploy the helloworld EJB sample. The
deployment wnet well and I am able to see test/Hello object under
Published JServer Objects. However, I am having trouble to call
Hello thru the Client application and got the following error:

Thank for the quick reply!
There were 2 things I did wrong and both of them you pointed out.
I left off sid in the url and did not include the jar in my
project. Now it works!
Thanks again!

I'm having trouble making calls with my Iphone 4. When I try to, the person on the other side can't hear me, and all I can hear are noises. But when I use apps like Viber or Facetime, I can make calls just fine! What may be the problem?

Did you fix the problem? I have the same problem and it has been pain in the neck.

I hope this helps.

3-way call trouble - "merge calls" grayed out

I'm having trouble merging calls when I try to do a 3-way call. I can make the two separate calls but the "merge" button is always grayed out. I have the service through my provider and an iPhone 4s. Thanks for any help!

Thanks, diesel vdub...I actually did contact the carrier and everything was a-ok on their end. Any other suggestions?

I'm having trouble with something that redirects Google search results when I use Firefox on my PC. It's called the 'going on earth' virus. Do you have a fix that could rectify the vulnerability in your software?

I'm having trouble with a virus or something which affects Google search results when I use Firefox on my PC ...
When I search a topic gives me pages of links as normal, but when I click on a link, the page is hijacked to a site called 'www.goingonearth.com' ...
I've done a separate search and found that other users are affected, but there doesn't seem to be a clear-cut solution ... (Norton, McAfee and Kaspersky don't seem to be able to detect/fix it).
I'd like to continue using the Firefox/Google combination (nb: the hijack virus also affects IE but not Safari) - do you have a patch/fix that could rectify the vulnerability in your software?
thanks

''' "... vulnerability in your software?" ''' 
And it affects IE, too? Ya probably picked up some malware and you blame it on Firefox.
Install, update, and run these programs in this order. They are listed in order of efficacy.

These programs are all free for personal use, but some have limited functionality in the "free mode" - but those are features you really don't need to find and remove the problem that you have. 
''Note: If your Malware infection is bad enough and you are mis-directed to URL's other than what is posted, you may have to use a different PC to download these programs and use a USB stick to transfer them to the afflicted PC.''

I'm having trouble facetiming. I live in mexico and I don't know if that is the problem. Everything seems to be in order, it rings on my end when I call someone but it doesn't get through to them. Same is true when someone calls/facetimes me.

I having trouble with my i phone 4 ...when i make a call the other person cant hear me

im having trouble with my i phone 4 ...when i make a call the other person can not hear me

Kayla, check the grill that covers the microphone (bottom left next to charging port) and make certain there isn't any dirt, makeup, spilled soda clogging the grill causing it to fail. My sister had a similar issue with her earphone and while I was in the process of replacing it for the third time I decided to check the grill under a very bright light and it was totally clogged up causing her not to be able to hear her phone calls. Use a Q-Tip dipped in hot water and gently wipe the grill. Just barely moisten it, no need to go crazy with the water. Might as well clean the earphone and speaker on the bottom right too. Anyhow, that could be what your issue is and if so it's a really simple fix. If that doesn't help just replace the microphone. It'd cost maybe $5 and ten minutes of your time to do. Good luck, John

Having trouble calling my work voicemail from the iphone - it doesnt recognize the dtmf tones

i am having trouble calling my work voicemail frome the iphone - it does not recognize the DTMF tones from the dialpad. we have justgone to a new IP voice system at work

we use a remote dialling code to divert our office landlines to mobiles, we have had awful trouble with the iphones in doing this with the number stored as a contact, We also have trouble dialling the number direct from the keypad it still comes up with error and says the number has not been recognised.
I have managed to sort out how to remedy this for us on this end and i will give an example below, the 'p' represents a pause
(numbers changed for security)
original phonebook contact stored, please notice the pauses 'p' only the first single pause
01223495684p*65*4530*01223456456*07555456456#
the new number now stored in the phonebook with the extra pauses 'p'
01223495684pp*65p*4530p*01223456456p*07555456456# as you can see we dial a landline number and then give a pause for the next tone to cut in, then we enter the overall divert code, after this we enter the pin code followed by the landline number to divert and finally the mobile number that will be taking the calls and finishing off with hash.
all our other phones except the iphone will dial this number and work correctly with one pause at the beginning, I have now tried thios with two pauses at the beginning and one pause between each section and it now works fine,
This has cured our problem using the io5 iphones 4s. we could not dial these numbers with the iphones for nothing, all other phones work fine. When you have a bluetooth headset connected the problem is even worse.
this has cured our problem and hope this helps you all also

I have a new Mac, I am having trouble accessing Bill Pay on my banking site. After 2 unsuccessful calls to my bank, I thought I would ask here....is there something I need to do?

I have a new Mac. I am having trouble accessing the Bill Pay on my bank site. After 2 unsuccessful calls to my bank I thought I would try here. Is there anything I need to change in my settings?

We can't really say without more information. It could just be that your bank site stinks and only works in Internet Explorer, which means you can't use it without Windows. It could be that it relies on Flash or Java and you don't have either installed. Your bank should be able to tell you if it requires either of those, and we can tell you where to get those things. Or it could be something else entirely.

HT1338 HAVING TROUBLE INSTALLING A GAME CALLED WORLD OF WAR CRAFT 3

HAVING TROUBLE INSTALLING A GAME CALLED WORLD OF WAR CRAFT 3

If you're talking about WoW, it's already playable in Lion, just download the latest version. If Warcraft 3, as I said, it's probably never going to be updated by Blizzard at this point. It's a very old game and would probably not earn them enough to be worth the expense.

I am also having trouble with my cursor freezing after installing Mavericks. Never did it before. I called tech support at Apple and they had me restart computer and mouse together from a complete shut down. So far has seemed to work.

I am having trouble with my cursor freezing between applications after installing Mavericks. Called Apple on my 3 year warranty and opened a case. They suggested a complete shut down of computer and turning off mouse. Then a reboot and turn on mouse. So far iit has seemed to work. Hope this continues??
Hope it helps others.

I think you can solve your problems by removing your AppleID email address from BOTH the Messages setting on your iPhone and the iMessages settings on your Mac.
On iPhone:
Settings > Messages > iMessage > Dissabled
Settings > Messages > Send & Receive > touch the "(i)" < touch "Remove This Email"
On Mac:
Open "Messages" application
Click "Messages menu > Preferences
Click "Accounts"
Select your AppleID account
Under the "You can be reached for messages at" settings, uncheck your AppleID email address and your phone number
Then uncheck the "Enable this account" setting
And lastly, ask all of your friends with iPhones to delete all iMessage conversations (blue bubbles) in their entirety.
To test, send a friend a new text using their phone number (not their email address) and watch the color of the bubble. If it's green then you are using SMS.
