First, please put your code inside code tags. There's a nice little button. All you have to do is paste your code, highlight it and press the little code button. Thanks.
I had to make some adjustments to your original post. Either you had some closing braces in the wrong place, or you hve no idea what you're doing. I'm going to assume that Class1 is in a file named p1/p2/Class1.java and Class2 is in p1/p2/Class2.java.

As far as trying to power up your device, make sure it has a good charge and then hold the button on the top of the phone and the home button on the faceplate together until the apple appears on the screen.

Hi, when ever I'm using 3G, on my Iphone4 sim stops working and network is lost, this started after I updated my phone with 6.0.1(10A523)version. Please help how to solve this problem. Thanks.
Photos/videos in the Camera Roll are not synced. Photos/videos in the Camera Roll are not touched with the iTunes sync process. Photos/videos in the Camera Roll can be imported by your computer which is not handled by iTunes. Most importing software includes an option to delete the photos/videos from the Camera Roll after the import process is complete. If is my understanding that some Windows import software supports importing photos from the Camera Roll, but not videos. Regardless, the import software should not delete the photos/videos from the Camera Roll unless you set the app to do so.
Photos/videos in the Camera Roll are included with your iPhone's backup. If you synced your iPhone with iTunes before the videos on the Camera Roll went missing and you haven't synced your iPhone with iTunes since they went missing, you can try restoring the iPhone with iTunes from the iPhone's backup. Don't sync the iPhone with iTunes again and decline the prompt to update the iPhone's backup after selecting Restore. -

Shivendra.Hi,
The following should be verified:
(1) check what DB instances the listener currently is aware of. This can be done with the command 'lsnrctl services'.
(in case you listener does not have the default name LISTENER, then use 'lsnrctl services <listener name>' )
(2) Perhaps there is an issue with the dynamic instance registration, even though the error code is different, you should nevertheless check the points from note #563574.
(3) Verfiy the value of the parameter local_listener (see mentioned note). Since you have changed the listener, the parameter might still be wrong.
In case local_listener is correcly set you should give the command
ALTER SYSTEM REGISTER;
a try.
Best Regards,

Please help me to solve this problem.
Hi , can someone help me to solve the following problem:
1) I wrote two different client and server program, (Using UDP)
2) In the server side for testig I wrote some code like when a client sending message to server
a) server find on the database only senders IP address then server return the message to sender
b) Again if server find out other IP address too then it returns to them too
3) but it working for (a) , but not for (b)
4) Actually, its sending message but client not getting it
So, can some tell me, how to modify server or client side
Server wont reply the msg to the same IP address/ Sender who sent the message.
Server will reply the message to other person..
For example, Alace, Bob and Carrry are three clients. Alace, Bob, and Carry are online now. When they get online server save there IP address.
Now, Bob sends a message to server , then server will send the message to Alace and Carry. Not to the sender Bob.
Thanks]
I am giveing a pice of coding of server side
else
IPAddressObject addressObjectt;
onlineUserList.reset();
for(int i=0; i<onlineUserList.lengthIs(); i++)
addressObjectt=(IPAddressObject)onlineUserList.getNextItem();
IPAddress=addressObjectt.getAddress();
System.out.println("\n this is not same : "+IPAddress);
if(addressObject.compareTo(addressObjectt)!=0)
System.out.println("\n this is not same : "+sentence);
String cSentence=sentence.toUpperCase();
sendData=cSentence.getBytes();
DatagramPacket sendPacket= new DatagramPacket(sendData, sendData.length, IPAddress,port);
System.out.println("\n aaaaaaa : "+IPAddress);
client.send(sendPacket);
else
System.out.println("\n this is same : "+sentence);
String cSentence= sentence.toUpperCase();
sendData=cSentence.getBytes();
DatagramPacket sendPacket= new DatagramPacket(sendData, sendData.length, IPAddress,port);
client.send(sendPacket);
System.out.println("\n this is same : "+cSentence);

Not sure why are you getting this kind of error (which is pointing to a URL with Jpg file) while creating a journal.
Could you please bounce your server once and try..
Please let us know if the error/warning stopping you to enter a journal in GL??
We don't think profile option is a show stopper here.... We assume that you have assigned Sets of Books, MO: Operating unit & HR USer Profile option at Responsibility level correctly....
