This means that you try to call a method of an object which was declared but not instatiated.
Example:
Object example;
example.toString();
this will return an error since the object example was not instantiated.
In order to let this code work. You have to do the following.
Object example;
example = new Object();
example.toString();
This will work.
Exception occurred during event dispatching:
the rest of the line represent the error stack which shows where the error occurs.
As I can see from those lines.
You will have forgotten to instatiated some awt object somewhere in your application.

We are using the Azure server for our web services. Server is generating an error "Unable to connect to the remote server". What is this error means

Hello,
Did you means that you use the Windows Azure Virtual Machine DNS name as the server name in the Reporting Server Web Services URL?
For example:
Report server:http://uebi.cloudapp.net/reportserver
Report manager:http://uebi.cloudapp.net/reports
If you want to connect to Report Manager on the virtual machine from a remote computer, you should create a virtual machine TCP Endpoint and open the port in the virtual machine’s firewall. By default, the report server listens for HTTP requests
on port 80.

What does this error message mean and how do I solve it? "Sorry, one or more of the following command-line tools was not found: /usr/bin/lsbom, /bin/pax, /bin/mkdir, /bin/chmod, or /usr/bin/update_prebinding."

When I try to open up this program, Pacifist, I receive this error message. Here's a screenshot. http://i.imgur.com/v717w.jpg What does this error message mean and how do I solve it?

It sounds like some of the Unix Executable commands were removed (or the permissions to those were modified) out of the /usr/bin/ folder. You can try opening disk utility and repairing permissions on Macintosh HD or you can reboot your computer and holding down option-r when it comes back up to reinstall Lion again. This will not delete your personal information or applications you have installed but it would be best to back it up to Time Machine before you do. The article on how to do this is here. (http://www.apple.com/macosx/recovery/) I have had to do this before and it works like a charm. It should fix your issue but grab a cup of coffee because its going to take about 35 - 40 minutes depending on how fast your computer is.

Often it suggests issues with device filters in your registry. But it's probably best to check the situation more closely.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

I am connecting to an Oracle8 DB, but it seems tat i have problem connecting to it and retrieving record from the database. Can anyone help me how to establish a connection to my Oracle DB??
Need help urgently. thanx.!

have you tried simple jdbc connection?
Driver drv = Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection(oracle:jdbc:thin:@myhost:1521:instance, "usrname", "password");
If this works you're able to connect! so check that your oracel datasource is well specified in your deploiement descriptor and that your bean references this datasource.
hope it helps

E61 - Latest Firmware - What does this error mean ...

What does this error mean?
Profiles in same realm must have same user name
I am trying to setup a PBXes.com account and since I upgraded firmware I get this message now, when trying to save a profile.
There were no other profiles in the same prior, is this somethign stuck from an old configuration.
Rae

Actually I just fixed it by deleting the profile and entering it as new. I saved it after each step of the profile creation process and was able to reproduce the problem when I entered a password on the proxy settings but not yet on the registry settings. Once I entered the same user name and password on both proxy and registry, I was able to save the profile again. So I guess I must have mistyped the password in one of the settings before.

It's a different method of backing up your iPhone 4s. This article covers the differences between the two and may actually be able to help you choose between them:
