Uncaught exception:java.lang.nullpointer exception

i recently upgraded to os 4.5 on my 8310 it works fine .but when i 1st turn on my phone i get this message .does anyone know what this means ?

Did you installed any application after upgrading the OS? If yes then remove and have a restart to your device. If that too doesn't solve the issue than reinstall the OS again.

Java.Lang.NullPoint.Exception in OWB Mapping

Hello Everybody
We are building Data Warehouse using OWB Repository 9.2.0.2.0. When we are validating or deploying the created map we are getting Java.Lang.NullPoint.Exception. This leads to blank screen. We are unable to recover the map. Sometimes, synchronization works to recover the map, but not all the times.
Is there any solution to it?

Java.lang.NullPointer Exception error in webi

Hi All,
When a opening a webi report a user is getting java.lang.NullPointer Exception error in webi for a single report.
Other reports which were build from same universe are working fine. The issue is only with one user and one report.
Environment:
Business Objects XIR3
Java 6 ,update 3
IE version 7
Web Application Server - Apache Tomcat
Thanks in Advance....

Hi,
Check whether the same user is able to open the report in some other machine?
What happens when the user is trying to open other reports? Does he gets the error again?
If the reports is working with other machine, check the java version of the machines.
If the report is working with other users, it not possible that the universe is damaged.
This issue cannot be a rights issue. It has to be something with the report, java, or the universe.
Please check the above details and let me know.
Regards,
Shreyash.

Hi,
Please find the following setting for configuration .
Goto SPRO then follow following path
Personnel Management - > Employee Self-Service -> Service-Specific Settings -> Working Time -> Leave Request -> Processing Processes
Create Rule Groups
1st you need to create the role group ( following is E.g )
Role group              : 00000001
Name of Role group : SAP Standard
Define Processing Processes for Each Rule Group (following is E.g)
Role group              : 00000001
Name of Role group : SAP Standard
Start Date               : 01.01.1800
End Date               : 31.12.9999
Specify Processing Processes for Types of Leave ( for E.g )
(click up on new entry )
Role group              : 00000001
Name of Role group : SAP Standard
PSG                       : 01
A/AType                 : 0420
Type Text               : Seminar/course/training
Start Date               : 01.01.1800
End Date               : 31.12.9999
then once you make entri here you need to click up on details ( select that row then Ctrl + Shift + F2 )
then it will open change view of Processing Processes for Types of Leave ( here this screen for absene type 0420 )
in this screen
Start date in the Past
Put radio button on "Processing Permited to Rec. limit".
start date is the current date
Put radio button on "Processing is perminted"
Start date in the Future
put radio button "unrecstrikt processs is perminted"
tick mark at Display field next ....
tick makk to request may ..........
system response
tick mark "request has to be aproved'
like this you can make the SPRO setting for other leave othere than 0420 ..in the "Specify Processing Processes for Types of Leave"

Read file gives java.lang.Nullpointer exception

I am reading to read a ".txt" file created by "python code" and stored in my directory.
If i comment the python code and store the file ("statusfile.txt') in the directory, the code is able to read the file. but when i uncomment and run the python code to generate the file ..it gives java.lang.NullPointerException.
the two functions for reading the file and running the python code are separate but in the same class and are also called in one JSP. Does anyone have any suggestions.
Someone did suggest me to use getResourceAsStream.. but i do not understand where to use it .. in the class (where i am doing the readfile function or where in the runpython function which basically generates the file) I did tried using it in JSP and also in the class.. but nothing seems to work. Also as i saw the examples.. getResourceAsStream is used for uploading properties or config files. I just want to simplying read the simpel text file which is already stored in the directory and return a boolean to JSP if reading file was a success.
in short the algo is
ON JSP:
1) call class function to run python code
2) call class function to read the generated in step 1.
CLASS
1) function runpython()
// store generated files in the specified directory
2) function readFile()
//read file from specified directory
//return boolean
Any suggestions
Thanx

The problem is where is "your directory"?
Creating a file by new File("myFile.txt") just puts it in the current working directory.
Sometimes this is something like the bin directory.
Most web applications use ServletContext.getRealPath("/")
This turns a website relative reference into a file reference on the local machine.
So you can say getRealPath("/index.html") and it will return the file (for example) C:\tomcat\webapps\root\index.html
On to suggestions:
Null pointer exception?
Where is it coming from? Catch the exception and print a stack trace, to see if you can determine which line of code is causing it - which variable is null. Is it the actual file, or something you use to create the file?

Java.lang.NullPointer exception and operating systems

Do different operating systems handle the NullPointer exception differently? I have an application that has a screen come up when you click a button. However, the app attempts to process some data before bring up the screen. Sometimes the data is null. The application works fine on linux red hat. However, the screen does not come up on HP Unix. I am not looking to fix the code (even though it may need fixed), but I am looking for an explanation why app works differently in this regard.

Do different operating systems handle the NullPointer
exception differently? Nope.
My guess is that the different OSes have different threading models. In one case X amount of work gets done in the non-GUI thread before the GUI thread tries to do its thing. In the other OS, X+1 amount of work gets done, leading to different states for the GUIs to act on. This is almost certainly a bug in your app.

Hi Sandeep,
I have a solution through which i have resolved in one of my projects.
Just incresase the heap size on Tomcat server and restart it. Say if it is 256 make it double as per your requirment.
This issue occurs when your QaaWS tries to get more data .
Hope this may solve your issue.
Let me know if the problem is not resolved.

Cannot pair Bluetooth with 2008 BMW - 'Uncaught exception: java.lang.Classcast Exception' message

I have been trying to pair my 8100 with my new 2008 model BMW 135i built in car kit using Bluetooth set up. The phone finds the car kit and the two appear to pair (confirmation numbers entered etc) but then the Smartphone screen freezes and the following error message appears 'Uncaught exception: java.lang.Classcast Exception'. The phone cannot then receive or make calls (won't even turn off until battery removed). Have been through the whole process several times. The car will pair with other phones and my 8100 will pair OK with other devices. Can anyone help?
Thanks, Paul.

I have got aorund the problem by disabling address book transfer. I can now receive calls and make outgoing calls by either dialling on the blackberry itself or using the BMW idrive controller. It is better than nothing and my main use anyway is for incoming calls while driving. The whole idea of the integrated system was to be able to scroll through the address book on the steering wheel buttons and view the address book entries on the satnav screen.
I have had similar problems in the past with an integrated system in a Porsche. The Blackberry never establised bluetooth contact with that system at all.

Java.lang.outofmemory exception

Hello,
I have an application, that writes several thousands of records into a file and transfers the same to the server. I am encountering an exception "java.lang.OutOfMemoryError" exception.
I had checked this forum earlier and found a solution that recommended an increase in the memory slot allocated to the JVM. Despite, an increase in this slot from 256MB (eclipse's default) to 1024 MB, my problem still persists. I had updated the eclipse.ini field from "-vmargs -Xms40m -Xmx256m" to "-vmargs -Xms40m -Xmx1024m". Is there anything else that I need to do, to take care of this problem? I am using green threads in the application, does this have anything to do with the above mentioned exception?
Thanks!

I am using
green threads in the application, does this have
anything to do with the above mentioned exception?It wouldn't be hard to find out. Create a new java class where the main method does the same work; writing several thousands of records into a file and transferring it to the server.
Maybe it's all the other variables you have in your application that are cutting into the memory. But can you really reduce them?
Are you loading all thousands of records to memory (I'd imagine in a hashmap or a list) all at once? Like said, do this in smaller chunks, store the records in memory just one at a time and see if that works. It will be slow but it won't run out of memory. Then increase your "batch size" until you find the optimum.

Hi plZ help me to fix the error to my Blackberry 9300 Uncaught exception: java.lang.NullPointerException

; hi good plzz do help me to fix the error to my bb9300 i just update my bb9300 the the i see
error b Uncaught exception: java.lang.NullPointerException anyone here can help me to fix i appreciate

I am guessing that you are not a Java developer, and it is not your application that is causing the Null Pointer Exception.
It sounds like you have updated the OS on your Blackberry device and one of the applications that you have installed is not coping with the upgrade.
If you press on an application icon and then that causes the error, then you know there is a problem with that application and so you need to report this to the developers of that application and get an updated version.
If this is happening when you restart your device, then it appears that one of the installed applications is failing at start up time and so it is not obvious which application. So you need to see which of your applications doesn't appear to be providing all the functions it used to, and it would be a good guess that it is that application that is causing the problem. Again you need to go back to the developer to get an update.
Let us know if that does not help.
Also you have posted in the Java developer forum. If this really is not your program causing the problem, then I suggest a better place to post a question relating to the 9300 is in the appropriate device forum here:

Uncaught exception java.lang.ArrayIndexOutOfBoundsException in J2ME

hi all,
i found a strange error (uncaught exception java.lang.ArrayIndexOutOfBoundsException) every time when i tried to developed a MIDlet and servlet to retrieve data from database. can anyone tell me why this error occur? this is example of MIDlet code:
public void checkResult() {
HttpConnection conn = null;
InputStream is = null;
OutputStream os = null;
byte[] receivedData = null;
String userid = "123";
try {
String url = getAppProperty("Result.URL");
conn = (HttpConnection)Connector.open(url);
     byte postData [] = ("userid=" + userid).getBytes();
conn.setRequestMethod(HttpConnection.POST);
conn.setRequestProperty("User-Agent", "Profile/MIDP-1.0 Configuration/CLDC-1.0");
conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
     conn.setRequestProperty ( "Content-Length", Integer.toString (postData.length));
conn.setRequestProperty("Connection", "close" );
conn.setRequestProperty("Content-length",Integer.toString(postData.length));
     os = conn.openOutputStream();
     os.write(postData);
     os.close();
     is = conn.openInputStream();
     String contentType = conn.getType();
int len = (int)conn.getLength();
if (len > 0)
receivedData = new byte[len];
int nb = is.read(receivedData);
else
receivedData = new byte[1024];
int ch;
len = 0;
while ((ch = is.read()) != -1)
receivedData[len++] = (byte)ch;
response.setText(new String(receivedData,0,len));
display.setCurrent(outputForm);
catch (IOException e) {
System.out.println(e.getMessage());
e.printStackTrace();
finally {
try {
if (is != null) {
is.close();
if (os != null) {
os.close();
if (conn != null) {
conn.close();
catch (IOException e) {
from alice

That would be a point where I miss bounds checking on your part:
receivedData = new byte[1024];
int ch;
len = 0;
while ((ch = is.read()) != -1)
receivedData[len++] = (byte)ch; // what happens if more than 1024 characters come along??
}Otherwise the exact line of error, the stack trace or some context would be helpful.

8350i uncaught exception java.lang.NullPointerException after hard reset

basic info:
8350i
v4.6.1.204 (Platform 3.0.0.73)
Desktop Manager 4.7
everything is good except that i've been using two batteries, one in the phone and one in a charger. when the phone's battery is almost drained i swap it with the charged one which of course causes a hard reset.
this procedure was working well for at least a week or two until last month when i swapped batteries - after the hard reset i got
uncaught exception: java.lang.NullPointerException
i could make calls but all other software seemed corrupted... virtually nothing else worked... icons missing etc.
tried all sorts of solutions but the only thing that fixed it was a full on device software erase/reload, then a data restore from previous backup. at the time i figured it was just a random thing and was glad to learn how to do a complete software reload.
then yesterday it happened again (again, immediately at the end of the security check after hard reset). now i'm afraid to swap batteries because it would appear that every time i hard reset there is a 10% (my guess) chance of software corruption and a complete reload takes a significant amount of time.
has anybody else noticed this? does anybody have a solution?
can i swap batteries without a hard reset; i.e. swap while plugged into power? i haven't tried this yet for fear of causing my BB harm.
any help is appreciated,
john d.
