My application is not even in the stack trace, so I have no idea what is going on. I am trying to connect to a service when it happens. How can I fix this problem? Thanks, Isaac Waller ...
I have a project in Eclipse. When I run it from inside Eclipse, everything works just fine. However, when I run the Ant build script and execute the JAR either from the command line or using a batch script, I get a NullPointerException. The NullPointerException in question is being thrown from a third-party JAR that I compiled from sour...
I'm trying to do something to track down the problem, but there's not much I can do until paintContents, and everything there looks good through my debugger, but I'll double check to make sure I didn't miss anything. At the very least, I would like to know how to silently handle these (such as catching them and being able to output a mea...
I've always wondered why the JVM doesn't tell you which pointer (or more precisely, which variable) is null when a NullPointerException is thrown. A line number isn't specific enough because the offending line can often contain numerous variables that could have caused the error. Is there any compiler or JVM flag that would make these ...
I have inherited a large c++ code base and I have a task to avoid any null pointer exceptions that can happen in the code base. Are there are static analysis tools available, I am thinking lint, that you have used successfully. What other things do you look out for? ...

I initialize a String variable to null.I may or may not update it with a value.Now I want to check whether this variable is not equal to null and whatever I try I get a null pointer exception.I can't afford to throw nullpointer exception as it is costly.Is there any workaround t...
I am experiencing a crash in my app when I quit (via the back button) out of my Activity. So far as I can tell this is happening in the Android codebase and not mine, but I'm not completely convinced of that. Here's the stacktrace from adb: AndroidRuntime E Uncaught handler: thread main exiting due to uncaught exception AndroidRuntim...
Hi, all. One of my applications runs on a Windows Service instance of Tomcat 5.5, running Java 1.6. We've got an issue in the code where the application creates a NullPointerException if a SOAP request times out. We had an issue, this morning, where the component on the other side of the SOAP request was unavailable. The result was a...

I'm running the following line in an Activity, which is within the same application, but in a different package: AppObject appObj = (AppObject)this.getApplication(); // FYI: AppObject is my extension class of Application. It returns only a null pointer, while when I move it to the "main" package and run it from there it returns the ap...
Hi all, I've been struggling with this issue for a little while now. Found several posts about it but none solved my problem. It will probably have something to do with the fact that a SecurityContext is boud to a specific Thread but even then I do not know how to solve it: Consider following code to retrieve the user that was logged i...
I'm writing two classes to handle simple auctions. I have a class ready and working, which handles the operations for a single auction, and now I'm writing another class like an auction house, to keep track of all the auctions available. When testing the following part of the class: import java.util.ArrayList; public class AuctionHouse...
I'm writing an app for Java ME, and I need a class for holding some data(PhoneBook). When I'm trying to launch this app, I'm always getting a nullPointerException. I'm calling the constructor of a class, and it allocates memory for 10 elements, so it shouldn't be null. What am I doing wrong? import javax.microedition.lcdui.*; import ja...
