Re: Java 2
rwk, The java 2 implementation of Blackdown is great; a lot faster than java 1, but there's a little deadlock in GUI's which stops it from use for production systems, for the rest: good stuff.

JDBC useing MySQL and mm.
tpeter,
This sound like some problems I had. I was trying to import
the mm stuff but this wasn't correct. Here's a a module
I finally was able to make work. Hope it helps.

off topic (code problem)
hi all,
I'm having a problem with a piece of code, and I'm going nuts here.
here's the piece, plese help
public STable(Vector fieldsv, Vector rowsv)
{
originalRows = (Vector)rowsv.clone();
rows = (Vector)rowsv.clone();
...
}
now, the problem is that when rows changes originalRows changes too.
the parameter is a vector of vectors, so I'm guessing that's messging
things up, right?
Any help would be appreciated
TIA

How do I create a 1-bit depth graphics in memory?
Hi, I am currently trying to create a 1-bit depth graphics in memory. I do not need color capabilities, just black-and-white. I am using a buffer made up of integers but it is a waste of memory when I can use 1-bit for a pixel instead of 32-bits. What is the best way to do that? I need to switch to the more efficient way since Java complains OutOfMemory exception on large images Eric Chao [EMAIL PROTECTED] Merlin Software Technologies Inc. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Re: How do I create a 1-bit depth graphics in memory?
I've run into this myself, and it seemed like the ColorModel class assumes that you'll use either 1 byte or 1 int for each pixel. So it seemed like the best you could do was switch to 8-bit indexed color, which is at least a 4x improvement. If there is in fact a way to use a 1-bit color model, I'd love to hear it!

You need to clone every element in the Vector also. By default, Vector's
clone() only does a shallow copy, whereas you seem to want a deep copy.
Remember that Java uses a reference data model, so when you clone the
Vector, the second vector "rows" has copies of the references from the
first vector "originalRows", but the references STILL point back to the
original objects in "originalRows". Thus, adding or removing elements
from the cloned vector will work as expected, but changing the actual
elements in the vector will affect the original.
A basic Java mailing list such as those hosted by Sun or the Java
newsgroups will be more helpful here.

Excuse me, but I'm new in this. I'm still configuring the JDK 1.1.7 in a computer with Redhat 6.0. What environment variables should I set and how should I do it? I'm trying to configure AnyJ but when try to execute it I get the error "Class not found java.lang.Thread" Thanks Hector Gibran Ceballos Cancino
Re: Path
First all make sure you have jdk1.1.7_v3 installed (glibc2.1 compliant). If you are trying ot run AnyJ with the 1.1.7 jre, I suggest IBM's JRE, its much MUCH faster running AnyJ, but if you are settings up the JDK to work with projects, I would suggest using blackdown's 1.1.7 or 1.2 jdk, I've had better lcuk. When I use IBM's jdk/jre I get the error you said you are getting compulsively, I never took the time to trouble shoot it. -Riyad P.S.> For all of you AnyJ users out there, a big upgrade is comming up in another few weeks with a lot of bug fixes and features added (not all of them right away though). Woohoo!

Can someone tell me what the differences are between IBMs port and the blackdown port?
