I've been working on a lesson in logging in Java, formatting in XML. I'm trying to add an appender to e-mail the error log, but can't seem to get it to work. Is there a piece I'm missing? The rest of my appenders are working fine. The error I get is that it cannot create an appender of this type. The console also seems to think that I defined the appender after I call for it, but it is above. Here is what I put together:

I have the following code that comes directly from the book Core Java vol 1. The last two statements are mine but when I change the last statement's String the message being logged doesn't change. For that manner when I change the level of the last statement the file doesn't update to the correct log level. What am I doing wrong?
Java Code:
public class LogTester { public static void main(String[] args) { if (System.getProperty("java.util.logging.config.class") == null && System.getProperty("java.util.config.file") == null)
[code]....
Forgot to say the file also only logs the old message and level from a previous recompilation
The last line seems half cut. Does that indicate that there is memory leak in my application? I have not seen the app throwing the out of memory error.
1) I don't know what regular expression can i use. 2) I want a line to check that preceding line should have //StorageVersion . 3) n then i will check any string between := K[' and '];. From above log file "'706146.0.22106932'" is the value that i am looking for.

I see the file "myApache.log" got created but there's no info in it when i re-test the error, I have other existing appenders and categories in this same file which do give output so I know it has nothing to do with the file or the path itself.
For my jsp file, the code editor shows no error, but the projects window shows an error. I built my project again, cleaned the project, restart eclipse twice and summoned cthulhu. But my project still shows an error. How do I find the cause.

So I am working on a school project and I have 2 classes, class FakeGravity contains all the properites and class BouncyBall is my driver class. For some reason when I try writing
FakeGravity gravity = new FakeGravity( );
I get an error. I am attaching an image of the error, and also attaching the program just in case you need more information. Also I was using blueJ to write the program

I have written the below program and while compiling i am getting error. The program and error details goes as follows,
//compute distance of light travels using Java long variable. class Light { public static void main(String args[]) { int lightspeed; long days; long seconds; long distance;
[code]....
I have given the Java file name as 'Light.java'. I have also verified the availability of the java file and compilation path. both are matching. Also, Java file name and class name defined are also same.
So I am finishing up a GUI that randomly rolls a dice and shows you the dice face from a file that I have on my computer. It compiles fine, but when I open the GUI and press the button "Roll" it gives me errors and does not display the images.
I'm very new to java code I'm currently learning about loops I've tried to write this for a statement in the program I'm making but its not working. I keep getting this message
LoanQualifier.java:26: error: illegal start of expression if (salary >0||<=250000) ^ LoanQualifier.java:28: error: illegal start of type if (yearsOnJob >0||<50)
I am pretty new to Java and I am working on a sample Search code from my textbook. I can't figure out why I am getting the following error because I copied the sample exactly as it is in the book. The error is illegal start of expression on the second to last line.
public class Search { public static final int NOT_FOUND = -1; public static int binarySearch( int [] a, int x ) { int low = 0; int high = a.length - 1; int mid;
Here is the code I am trying to execute its giving me the error with TextReader..

[Code] .....
The error is:
C: eha>javac WordCount.java WordCount.java:20: cannot find symbol symbol : class TextReader location: class WordCount static TextReader in; // An input stream for reading the input file.
