How do I resolve this I have reinstalled iTunes but it still doesn't recognise my ipod

I reinstalled Itunes a couple of times. I unistalled all programs that I never use, I updated all of my drivers, Windows swept my computer and found no problems. I have a yellow causion lite when I look at the USB-port with the phone connected. All other devices work without a problem.

In the middle of my last update it stopped updating in the because of an unknown source, and now my screen on my iphone is frozen with the apple logo and a loading bar. Help??

Unknown "source"? Do you mean unknown "error" followed by a number?
http://support.apple.com/kb/TS3221
Follow the instructions in the article. When you connect your phone again, you may have to press both the home and sleep/wake buttons until the Apple logo reappears, then continue pressing the home button until iTunes detects the phone in recovery mode.

RMI: Unknown source problem with connection & security

When I try to run the RMI server code, after I have granted all permissions in my policy, after compiling through RMIC generating my stub and skeleton classes, and finally after running the RMI registry, I receive an error. The error that I have been getting is pasted below. I have searched through several java forums trying to find an answer and have not found one. If you recognized this error, please let me know if you have suggestions. Thanks.

Replace Unknown Source in EcmaError (JSR223) with actual file name

Hopefully someone here knows how to do this:
In my code, all of the scripts are contained in .js files. Whenever one of the scripts contains an error, I get this:
javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: ReferenceError: "nonexistant" is not defined. (<Unknown source>#5) in <Unknown source> at line number 5
What bugs me is the <Unknown Source>. Multiple files are in one ScriptContext, and it can be hard to track down an error. It also looks horrible.
Is there a way to replace <Unknown Source> with the actual file name? None of the methods I see support passing a File object, so I'm really confused here.
Cross posted (and unanswered) at:

You may need to set compile debug option set to true.
I am not sure if my tip is useful for you, anyway good luck.

NullPointerException (Unknown Source) in Serializable class

Hi, I have a Serializable class, and I just added a new class variable to it, with its get and set methods. When I try to call either the get or the set method from outside the class, I get a NullPointerException, which refers to the method in the following format:
java.lang.NullPointerException
at setMethod (Unknown Source)
or at getMethod (Unknown Source)I'm very confused about why this is happening, and I can't seem to come up with any solutions as to why it happens only for this variable and not for the other ones.
I wrote the two following files, trying to reproduce this problem outside work, but I wasn't successful. Please help out!
import java.io.Serializable;
public class Profile implements Serializable {
     private static final long serialVersionUID = 1835312781905234523L;
    private String name;
    private String phone;
    private String city;
    private int age;
    public Profile() {}
    public Profile(String name, String phone, String city, int age)
         this.name = name;
         this.phone = phone;
         this.city = city;
         this.age = age;
    public String getName()
         return name;
    public void setName(String name)
         this.name = name;
    public String getPhone()
         return phone;
    public void setPhone(String phone)
         this.phone = phone;
    public String getCity()
         return city;
    public void setCity(String city)
         this.city = city;
    public int getAge()
         return age;
    public void setAge(int age)
         this.age = age;
public class ProfileTester {
    Profile profile;
     public ProfileTester()
         profile = new Profile();
         profile.setName("Nazli");
         profile.setPhone("650-234-1234");
         profile.setCity("Menlo Park, CA");
         profile.setAge(30);
         System.out.println("Name: "+profile.getName());
         System.out.println("Phone: "+profile.getPhone());
         System.out.println("City: "+profile.getCity());
         System.out.println("Age: "+profile.getAge());
     public static void main (String [] args)
          ProfileTester tester = new ProfileTester();
}

My guess is that your get or set method is a little more complex than a simple retrieval or assignment.
Make sure there are no null references in the body of those methods.

I'm sure it has something to do with the PropertyLayout (Layout Manager) that I'm using but I don't know what. It works fine on one system but does not work or another.

Hi Amit,
For starters, you are using an old version (1.0.2.2.1) of OC4J.
You can download newer versions from this web page:
http://technet.oracle.com/tech/java/oc4j/content.html
That page also has links to documentation, "how-to" documents and
sample code. Note that you also need to use compatible versions
of java.
Personally, I am using OC4J version 9.0.2.0.0 on SUN Solaris 7
with JDK 1.3.1 (also from SUN).
Also, (and if you don't already know about them) the following web
sites may also be useful to you:
http://www.orionserver.com
http://www.orionsupport.com
http://www.atlassian.com
http://www.elephantwalker.com
Good Luck,
Avi.

Sorry Amit,
I have absolutely no idea. However, have you tried these other two
forums:

http://forums.oracle.com/forums/forum.jsp?id=399160
Technologies > Other > Sample Code

The ODBC datasource must be configured as a System datasource. The database was configured as a User datasource so it was only visible on the local computer. That's why Business Views Manager could access the database.

Unknown source in stack trace

I've deployed my app onto iWS 6.0, when an Exception is thrown, the stack trace is displayed but it doesnt supply the line numbers where the exception occurred. Instead it says Unknown Source. how can I fix this, or get round this problem?

Check if your IDE is adding -g:none to the javac command line. If so, tell it to stop.

I'm not getting any errors during the compilation and my CLASSPATH is ok pointing to the ojdbc14.jar file, i'm running j2sdk1.2.4_12 and the error
when I'm trying to load applet is:
java.lang.IllegalAccessException: Class com.opera.PluginPanel can not access a member of class JDBCVersion with modifiers ""
     at sun.reflect.Reflection.ensureMemberAccess(Unknown Source)
     at java.lang.Class.newInstance0(Unknown Source)
     at java.lang.Class.newInstance(Unknown Source)
     at com.opera.PluginPanel.run(PluginPanel.java:406)
     at java.lang.Thread.run(Unknown Source)
What is wrong???
Any help would be very appreciable...
Thanx.

thank you for your valuable reply, but could you add
some more additional information?Since I don't write applets and don't know anything additional, no.
You might try posting your question in a forum that deals with applets and/or the Java security model. Or maybe if you wait long enough, someone who knows both JDBC and applet security will happen along and decide to answer your question.

Threading - Iterator.nextEntry(Unknown Source) - ValueIterator.next(Unknown

Hi,
I have a swing application, in which I am using two threads. One thread, is the "main", and the other, takes care of every update to the UI. My program works fine for a few seconds, but then I get a weird error which breaks my UI update thread. The error itself is:
Exception in thread "Thread-2" java.util.ConcurrentModificationException
     at java.util.HashMap$HashIterator.nextEntry(Unknown Source)
     at java.util.HashMap$ValueIterator.next(Unknown Source)
     at DrawFrame$allthread.run(DrawFrame.java:400)
     at java.lang.Thread.run(Unknown Source)
Which leads me to believe that the two threads are messing each other up. Lets take a look at some code.
This is the class which is created about 3 times a second, based upon when the user wants it to be.
class shooting { // this class is inside of the "allthread" class which implements Runnable
          private Point p;
          private Dimension size;
          private int deltaY;
          private int wtr;
          private boolean destroy = false;
          Rectangle recs = new Rectangle(); // This may have a factor
          private shooting(Point p, Dimension size, Color color, int deltaY) {
               this.wtr = 0 - size.height;
               this.p = p;
               this.size = size;
               this.deltaY = deltaY;
               recs.x = p.x;
               recs.y = p.y;
               recs.width = size.width;
               recs.height = size.height;
               rectangles.put(shotnumber, recs); // This may have a big factor as well (this goes into a hashmap)
               shotnumber++;
          public void paint(Graphics g) { // this part has a factor I believe
               if (g.getColor() != Color.red){
               g.setColor(Color.red);
               g.fillRect(recs.x, recs.y, recs.width, recs.height);
          So how I display this class on the UI, is like this:
          public void painters(Graphics g){
          for (allthread.shooting shot : shots) {
               shot.paint(g);
          }The painters method is called from my "public void paintComponent(Graphics g) {}", which I think updates when the computer thinks it needs to.
So I'm not exactly sure why its breaking, perhaps someone can tell from the error which I have listed at the top. I think one thread is trying to do something, which another thread is trying to do something at the same time to the same part of the code. That might not be it, but thats the best I have come up with in a week of confused droning about over this crazy madness.
Thanks for reading,
Nate
P.S. Thanks for the help, all questions will be answered in under 3 minutes - I'm right here watching this post until it is answered. Please ask any questions that you might have in order for me to provide you with information that I may have left out.

I don't know if you'd consider throwing an exception as breaking... but check this out too.

Hey I_ws,
glad I could be some help!
Other poster is right, you need some particular outputstream to output to, say you're outputting to a text file, (I can't remember your original post, but other outputs are similar)
you'd do something like:
DataOutputStream out;
//initialise with constructor...
         try{
              out = new DataOutputStream(
                  new FileOutputStream("log.txt"));
         }catch (FileNotFoundException e) {}
// creating a new data output stream to
//write data to the specified underlying FileOutputStream...
//output part:
inputStream.read(readBuffer, 0, i);
buffer.write(readBuffer, 0, i);
buffer.writeTo(out);
buffer.reset();
[\code]
hope that helps (and hope it runs!) I'm reading over my pathetic resume to counteract the ego boost of seeing my handle as a thread subject!
take care :)
