I have a program that I call repeatedly with Java.
The program will analyse data and write a line of results to a text file.
I would like to keep writing to the same file.
How can this be done?

I want to use assertions in my Java 5 code. The javac manpage says I
have to compile with `-source 1.4` to enable assert as a keyword, but
this also leads to java 5 features like enums not working anymore.

I am developing a simple Java Stand Alone App that shall be deployed on a CD
and executed via  AutoRun when the CD is inserted.
The App will have a few menu selections that shall launch System Apps like
the Default Internet Browser OR the default Quick Time Movie Player. I also

my old slickedit has gradually gone south trying to deal with new Java
1p5 syntax, so I decided to bite the bullet and try to do a project in
Eclipse.
The process was remarkably easy.

Just wondering if anyone can give me any pointers as to why my dialog is
taking too long to display, its a very basic dialog, a dozen textboxes
and labels and thats it. I'm displaying it modally with this code...
 private void btnAddActionPerformed(java.awt.event.ActionEvent evt) ...

I have a method which via Runtime.exec creates a new, potentially very
large, MySQL DB via its shell client:
public void loadData(String _dbname, String _host, String _dbuser,
String _dbpassword, String _scriptpath)  throws MySQLImporterException

I have this code:
---------------------
ResourceBundle bundle = ResourceBundle.getBundle( "EUWConfig" );
_loggerFileTemp    = bundle.getString("LoggerFile");

I have a object (myObject) with a value (ID) that is the "int" type. I have
to display this value in a jTextField (an extends of JTextField). As the
function setText in jTextField requires a String value, I have to add a
string "" into function setText as the following:

I read that the primitive datatype "long" has the following range:
long, 64-bit, from -2^63 to +2^63-1
i.e from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
Why am I getting then a range error in the following code:

I want to write a small program, which reads out training information from

Can someone suggest how to programmatically find out if midlet runs in
emulator vs. on the phone?
I don't want to start GPS thread if I'm testing midlet in the emulator.
Flipping static boolean bDebug flag all the time is lame. :)

Is there a JRE for PocketPCs (Samsung CPU)? And if so would it be J2ME or
J2SE?

Does anyone know of a free (i.e. free to download and no license fee)
J2ME JVM for Linux?
Thanks,

    I want to implement a disk cache for arrays, i.e., read/write
    byte[], short[], int[], etc.  Writing byte[] is no problem, but
    all other integer arrays can't (AFAIK) be read/written as a
    single chunk.  ByteBuffer only allows one short/int to be
