Error: boolean cannot be derefrenced. Help!
Error boolean cannot be derefrenced on the toString methods for:
public void firePropertyChange(String propertyName, boolean oldValue, boolean newValue) {
if ((changeSupport != null) && (oldValue != newValue)) {
String oValue = (oldValue.toString());
String nValue = newValue.toString();
changeSupport.firePropertyChange(propertyName, Boolean.valueOf(oValue), Boolean.valueOf(nValue));
Any Ideas?
byte, char, short, int, long, float, double and boolean are primitives.
They don't have any members (fields or methods) that you can access by dereferencing a reference variable using the dot notation.
If you want the String value of a boolean, there's probably a static method in Boolean, or you can use String.valueOf(bool).

If your wondering why i try to do it his way; For some strange reason the Boolean.valueOf(java.lang.boolean); method has been removed from Java.;ang.boolean in PP, so only Boolean.valueOf(java.lang.String) can be used.

Browser on 8310 SmartPhone Edge comes up with Critical Error and cannot be used, help please?
Hi, my name is Sater and I'm the lone I.T. guy for a small medical device company (about 40 ppl) based in Fremont, CA. So...
All of a sudden my vp of marketing comes in and says that he can't use the Browser function on his BB (8310 SmartPhone Edge) anymore. Naturally I'm intrigued, but this is a very strange error that pops up. It doesn't matter how many settings I go in and change, there's no budging it. Here is what it's telling me...
"Unable to connect to the selected Mobile Data Service, please try again later. If the problem persists please contact your administrator."
So I decide after about an hour of messing with settings and getting nowhere to call AT&T support. They said when that error comes up with "please contact your administrator", it's because it can't connect to the BES server anymore and that we would have to consult that with whomever runs that server. To give you a little background, we went through an outsourced Exchange provider called TheMessageCenter.com. They were alright, but my VP of R&D was pretty bent by some of the lack of customer service skills they presented to him when he was in an email crisis. Needless to say one of the very first missions I ever had at this place was to find a new email solution and integrate the migration.
So basically AT&T said they couldn't do anything and that I would have to contact our outsourced providor (TheMessageCenter.com, since we ran both Exchange and BES through them before we switched) back to get the settings cleared off the BES server hosting his phone Pin and info. I called them up, (mind you we had been away from TheMessageCenter.com for a good couple weeks now) and they claimed they had no other active processes running for our company anywhere on their BES servers or frankly, ANYWHERE lol. So naturally he's looking at me to fix this, and I am seriously stumped! Should I do some kind of Factory reset? If so, how can I load all his contacts/settings back the way he had it? Any help on this matter, (especially if treated as urgent... I know you hate to hear that, but I said it for all you I.T. guys haha) would be GREATLY appreciated!! Thanks

Fremont, CA 94539Hi,
The browser icon uses the BES service, unless you have signed up for the BIS ONLY servcie, wherein you get access to the internet through RIM's servers.
Since your servcie is a BES servcie the access to the internet is through the BES.
The MDS is a service running on the BES to authenticate you. (and thus the error)
So, No BES = No Internet access using the Browser icon!
So, I need a little clarificatuioin.
Did you move from one BES to another? Or did the user simply switch carriers?
It sounds as if you moved from one third company BES to another third company BES... Is that right?
If so then contact your New BES and ensure that they allow ppl to use the MDS servcie for internet access (Most companies charge extra for that feature! - Because they can!).
If your hosting the BES (Now), and it was Themessagingcentre.com before, then you need to Reactivate the Handset for the new BES. I have a feeling that he is now getting the emails through the BIS service and the handset wasnt wiped and so it is stil trying to access the old BES....
So can you please give details such as:
BES - where was it hosted:
BES - where is it now hosted:
NEW BES: Is the MDS service enabled and can people currently use it to browse?
Have you tested with other BB handsets to ensure you/user are clicking the same icons on both handsets (most ppl do different things to access in their own way, so simply asking them if it works doesnt help!)
The alternative is to use the expensive WAP browser. It will work but will rack up huge charges.
Let us know how it goes...

Iphoto rebuilding error. Cannot update please help!!!!!!!
my iphoto is updating and it says that it has to rebuild. But rebuilding is taking longer than an hour and pretty much shuts down my whole computer! I tried rebuilding again and it froze my computer which then turned black
HELP!!!Old Toad -
Again, I thank you for helping find my 8,000 photos - that was quite a scare.
Since you seem so knowlegable about iPhoto Library Manager let me ask this follow-up question.
It APPEARS my albums are gone (I can live with this) and in the space on the left where my albums would normally appear there is a list of events. These event folders are all empty. Should I delete these empty folders? I have not tried to do so.
I am simply curious as to whether there are additional tools or steps I can do to further recover things as they previously were?
BIG Thanks Again,

Hi,
To configure your ODBC DataSource, go to Control Panel ---> DataSources(ODBC) (If you are in a Windows environment).
Select the tab System DSN. If you have not added your data source, then do so by clicking on the Add button. If you have added the datasource, click on the Configure button to configure it.
Give the datasource name, then the database name.
You have to give the hostname, service name and server name. I guess, in most cases, the datasource name and host name will be the same, service name and server name will be the same. If you are using TCP/IP, the protocol will be onsoctcp.
There will be a file named Services under C:\WINNT\system32\drivers\etc where you have to give the port number for accessing this server.
It will be like this <service name> <portnumber>/tcp
Hope this helps...
best wishes,

I keep getting the error 306 cannot connect to the iTunes Network when downloading songs on iTunes. I've tried all the troubleshooting steps from the forums and my technical issues are still unresolved. I have Windows 7. Please help!!

Proxies, parental control settings and software, security or filtering software, or a bad iTunes Store cache can cause this.

To reset iTunes Store cache:
In iTunes, choose iTunes > Preferences (Mac) or Edit > Preferences (PC).
Click the Advanced tab.
Click the "Reset cache" button.
Click OK and see if the issue is resolved.
Adjust Parental Controls in iTunes:
Open iTunes.
Access iTunes preferences:
On a Mac: From the iTunes menu, choose Preferences.
On a Windows PC: From the Edit menu, choose Preferences.
Click the Parental Controls tab.
Remove restrictions on Parental Controls.
