OK, there was a lot of discusion about jikes on this thread, and rather
than post a bunch of little comments on each of the off shoot threads I'll
bundle it all up here
Riyad didn't miss anything, jikes can do a hell of a lot of files in the
blink of an eye. The bigest reason is that it is wr
Hello,
I am using Postgresql-6.4.3-2. I want to use JDBC. so as a first point
i need postgres.jar file.
when i execute the commands as follows it gives the error as follows:
#cd /usr/src/pgsql/src/interfaces/jdbc
#make all
javac postgresql/CallableStatement.java
postgresql/CallableStatement.jav
Actually, I'm pretty sure Jikes has built in automatic
dependency checking.
Try comparing the compile time for a "make clean" to a "make" (after
changing a few non-critical source files)
Admittedly, I haven't pored over the source code or anything, but I
thought I read somewhere that it does it

Jikes is really, really fast. Being on all local disk (NFS) makes a
huge difference. And I'm on fast machines - a 500 MHz Pentium III now,
I think.

Granted I don't know much about Jikes but 280 files in 5 seconds
amI missing someething?
Are you sure that jikes isn't just skipping over files that don't need to be
recompiled?

Simply use jikes (alphaworks.ibm.com), it's 100 times faster th
I have to agree. Use jikes and just recompile everything. I tried lots
of other hacks with makefiles a dep systems but the best way to make
sure it will work is to just recompile with jikes. I compile a project
with around 300 .java files and jikes rips through tham in a couple of
seconds.

Looks like you are using a glibc2.0 version on a glibc2.1 system. Try the
glibc2.1 version of Blackdown Java.

In Debian you can set the timezone with tzconfig. I don't know about the
other distributions. When I call TimeZone.getDefault().toString() it returns
the following:

Justin:
That should work, but I would have to do it in every program. I thought Java
was supposed to read that information from the computer. As far as I know
the JDK should get the default timezone from the computer it is running in.
What if I run the program in London, or California? Would I ha

How do I change from Eastern Daylight Time to Eastern Standard time. As far
as I know Calendar.getInstance() returns the default calendar information
for the machine. Right now my Linux machine is EST but Java returns EDT. I
though that by changing in in Linux it would change the JDK too. Is there
Yes .. we had the same experience too on Solaris. Native threads performed
much
better than green on a uni processor... Could be that the VM (which has to do
all the
work when using green threads) had some bugs while the OS stuff was much more
time tested and robust.
I also would like to
Hello,
so far I worked using the good old xemacs + Makefile combo.

I don't believe this is completely true. When using Java on Solaris, we were
set up to use green threads because it required a bunch of OS patches to use
java native threads. We ran into performance issues with green threads when
we would spin off threads to do background work. We finally decided

Native threads use the operating system to do the task switching.
Native threads are thus a benefit in multi-processor (SMP)
Are you setting a background color by doing a fillRect()?

Like my compadres before me said, native threads run at the OS level, and
therefore can access multiple cpus. However, it is my understanding that
this is the only time native threads should be used. On single processor
systems, green threads are faster, and you aren't limited by any process

Native threads are executed by the OS's native
libraries. Green threads are executed within the
Java Virtual Machine. Native threads are more
efficient, but green threads are *currently*
much more stable.

Native threads are O/S level purely. This would allow for parallel processing
and the like.
Green threads are "faked". The thread management is actually handled
by the VM, thus it cannot access things like multiple CPUs...
