Re: Singal use in Native Threads jdk
Interesting post. I've not read much about SIGSTOP/SIGCONT. Should native libraries be catching SIGSTOP to yield to the garbage truck then? How are you handling this inside the black box? Trent Jarvi [EMAIL PROTECTED] rxtx maintainer http://jarvi.ezlink.com/rxtx/
RE: serial port program
One problem we are encountering with rxtx is libc5 versions of the jdk native include files are not compiling clean with rxtx. If anyone able to dig around has the libc5 version installed we are interested in knowing if this is a problem with the libc5 jdk jni or rxtx. The only think on the rxtx side I can think of is maybe the flags -ansi -D_POSIX_SOURCE -D_BSD_SOURCE could be causing problems with the jdk jni. It works fine on the glibc version. This was not a problem with previous releases of the libc5 jdk/rxtx when I had libc5 systems around. There have been proposed changes to typedefs_md.h but I'm not convinced they are right.

JDK1.3 on Linux with SMP
Hi all, We're running Red Hat Linux 6.1, kernel 2.2.12 and glibc 2.1.2 on Pentium SMP machines. After several hours of running, sometimes one node will crash, giving: Exception in thread "main" java.lang.OutOfMemoryError <> In fact, it's unlikely that there should be any memory problems and this error does not occur when running on a single node. It's also disturbing that each java process takes only about 40 percent of the processing capacity on each node, even though it could go up to 7 percent or more. So, Sun's JDK 1.3 doesn't seem to be working on SMP machines under linux. Any advice? Thanks. __ Do You Yahoo!? Yahoo!

Could it be that the classpath gets truncated at 256 chars or something
like that? Try moving the "." to the front and see if that fixes/changes
the problem.

I've seen something like this before. It was immediately after I had updated my JDK from 1.1.3 to 1.1.6 and I discovered that there were still some hooks into the 1.1.3 code.

Re: slightly off-topic
You're right, you are missing something pretty basic.
If you have a method that must return type Object or any less specific
class than the class you KNOW it to be, you use an explicit cast when
referring to the returned reference. The Java runtime will issue a
run-time error if you make an illegal cast. Here is an example (I didn't
compile this so I apologize for any lazy syntax errors).
class StringArray extends Object
{
Vector arrayOfStrings;
StringArray( String [] args )
{
int i;
for ( i = 0; i < args.length; i++ )
arrayOfStrings.addElement(args[i]);
}
String getElement( int i )
{
// LOOK HERE * the next line casts a generic Object to a String
return (String) arrayOfStrings.elementAt(i);
}
};

The JIT is not the Java compiler. It is the "just in time" compiler which is also platform-specific and actually processes your classes at runtime to improve the efficiency of execution. The JIT on OS/2 does an excellent job. Java code executes very quickly (once its loaded). There is a hit in load time and the line numbers are lost in exception reports but things like compression/decompression utilities get a great boost. >I was looking for a linux ( VM ) and I thought clarify Java classes >need ( VM ) to run. >VM is platform specific.

Speaking strictly for myself, I believe people have two options; 1) take their own time to read the documentation and ask questions if they still don't understand, 2) pay an expert for the answers that they have invested the time to acquire. IMHO, those are you only choices. I understand time is valuable but no one owes anyone answers they aren't willing to work for or pay for. What John is responding to (and rightly so, as far as I am concerned) is the frustration that comes from answering the same questions over and over when he and others like him have taken the time to record the answers to the most commonly asked questions in the documentation that is shipped with the, need I mention FREE, product. Ask if you like, but, if you aren't paying for the answer, then accept what you get. Over time, I'm sure the documentation will get better.

Re: SIGSEGV 11* segmentation violation
Andrew, I'd like to say, in the nicest way possible, your java installation isn't using the correct libraries. Either you have a mixed set of libraries or some mixed java code. I would suggest removing previous versions of java that may use the old libc5 libraries, making sure you have a clean glibc installation, and re-installing the JDK or JRE (for glibc).

There is a known bug in the java_wrapper script that is very easy to correct.
There is a space missing in a call to a subroutine.
This is quoted from the revised script. Note the space after the

If you aren't using shadow passwords, you can just locate the password in the password file, call crypt() with the clear-text password to get the cyphertext and compare the cyphertext to what you got from /etc/passwd. The passwd utility was designed to be used by users and to be as secure as possible. Therefore, many tricks with redirecting i/o don't work. i.e. it won't let you! A note about crypt()... it needs a seed. The seed is stored in the first [2] characters of the cyphertext in the password file. I'm sure there is a similar approach that would support shadow passwords, I just haven't had a chance to look it up, yet. If you need a complete reference implementation, find the source code for "passwd". That is the great part about being in open-software systems! Douglas Toltzman

To all the good people who are working hard to grow java on linux; I, for one, appreciate your efforts. In my opinion, you are underpaid!

It is a sweeping description of any external executable content that allows further interaction and manipulation of embedded hypermedia content.

I am a little miffed that Sun knew about this before they led us down the Java road.

The >database and JDBC drivers are free. The database is faster than anything >else I've seen, including the big ones like Oracle, MS SQL, Informix, etc. This discussion really belongs on a database forum but here goes... Regarding performance of mySQL vs. Oracle or Informix; I hate to throw water on your fire but the real database engines (MS SQL is *not* one of them) use raw disk space and run on *real* unix systems with I/O subsystems capable of 80+ MB/s sustained transfer rates. We've worked with Informix engines supporting 250 simultaneous users on databases exceeding 100GB. I don't think its fair to even talk about comparing mySQL to a mature, commercial database engine. When trying to determine how a database engine might perform under a heavy load, one of the first questions you might ask is "does it use raw or cooked disk space?". If it uses cooked disk space (i.e. files in the filesytem), it will be significantly slower than a similarly well designed system that uses raw disk space. By eliminating the unnecessary file-access calls through the O/S, the overhead of I/O is reduced. Also, nothing can replace a *fast* SCSI subsystem. Don't even bother with IDE. Regardless of what they say about throughput, the IDE interface requires constant management by your CPU and doesn't allow overlapping I/O (most SCSI controllers allow 255+ concurrent I/O operations). In my experience, a slow SCSI subsystem on a heavily loaded system will outperform the best IDE. I am working intensively with postgreSQL. It has a rather rich set of features but it isn't ANSI compliant (yet). The documentation needs some work. After writing some complex triggers and external functions, I think I am going to write some HOWTO's and submit them to the postgres project team. Douglas Toltzman http://www.oakstrsft.com/

Is your CLASSPATH *really* set? Remember that, if you classpath is set in a .bashrc or .bashprofile then it only gets set in a bash shell. If you are invoking the JVM without a shell, you may want to take care that the environment is really correctly set for the process that will be exec'ing the JVM. I'm not sure what you setup is like or how your program gets invoked. However, your error sounds like the JVM cannot find classes.zip. I would begin by verifying that the environment is setup correctly and is getting passed along to the JVM. Douglas Toltzman
Re: Problem on mSQL.
This sounds like your DNS is returning a different name for your machine (when the IP is used to do a reverse lookup) than your machine claims to be. Otherwise, mSQL may be setup to use identd to verify the user (I haven't setup mSQL so I am not sure of its authentication scheme), in this case, you would need to configure it to "trust" the win98 client. You should ask this question on a mSQL forum. It is NOT a Java or JDBC problem.

Obviously you have limited knowledge/experience with the internals of object-oriented environments. I wouldn't be too quick to call the object construction/initialization sequence "dumb" without a detailed analysis. I would be inclined to say that calling an abstract/virtual method that must be defined in a subclass from within a constructor is a bad/dangerous programming practice that will yield unpredictable results, at best.

Re: jdk1.1.6 (sparc) dumping core
You may have had Kaffe installed which resulted in the library complaint. Do a "which java" to see if you are running Kaffe (it will be /usr/bin/java rather than /usr/local/jdk...).

The first time that I use the setVisible method of a dialog it comes up fine. After I hide it with setVisible(false), calls to setVisible(true) make the JDialog visible but only as a closed icon, and I must click on the icon to actually see the JDialog. This wasn't a problem on earlier versions of Blackdown, and I don't have the problem using Sun's JRE on Windows or Solaris or using the latest Apple MRJ for Mac OS X. What's up? Thanks, Dick --- End Message ---
building a JDK bootstrap on Linux
Steve: Building a JDK on Linux involves bootstrapping against an older JDK on Linux. What if I want to build that bootstrap itself from scratch (C/C++ code only)? Any ideas/pointers?
