Re: Read Huge File using Java - thanks
The finalize() method of any object is called by the JVM during a GC cycle. This gives the developer the chance to do any clean up before the object is removed from object heap. A good example of cleanup might be closing JDBC connection to a database or cleanly closing socket connection, Cheers Chris Quanyu Zhu wrote: > Hi,there: > Thanks for the comments on reading huge file using java . > Following some of your comments, right now I got a solution, which > tested for one 150M file just using 1 minutes and then draw the image. > That sounds a good result I can get. > Actually, I just used the bufferIO, and use only 1M tempery array to > store them and then compute the 1M info into the image array which is > more less than the whole file.

Re: has anyone got the native threads jdk1.1.7a1 running?
I am using 1.1.7 native threads on with smp(2) and it is kicks butt ! Although it was not stable until I went to version 2.1.131 of the kernel !!!

Re: How to invoke ?
Use java.lang.Runtime.exec() . The method comes in three flavors 1.) public Process exec(String command) throws IOException. 2.) public Process exec(String command, String[] envp) throws IOException. 3.) public Process exec(String[] cmdarray) throws IOException. Check the javadocs for the complete explanation of the api.

Hitting walls with JDK1.1.7v1a native threads
The Java app I'm developing on Linux is failing when I try to run with native threads. Before I spend a lot of time scratching my head over my own code, I need to ask: The failure is a SIGSEGV (segmentation fault). Should this ever happen as a result of my app's behavior? My inclination is to suspect the JVM. The app runs beautifully with green threads. Nathan Meyers [EMAIL PROTECTED]

The place where I heard about this list is http://www.blackdown.org/java-linux.html And that's where they also tell you how to get off the list ... By the way, by entering the keywords +"java-linux" +mailinglist +unsubscribe in www.yahoo.com I found the following URL http://summer.snu.ac.kr/~djshin/linux/mail-list/ which contains of mailinglists for linux. And it has buttons that one can click subscribe or unsubscribe from those mailinglists. Easy to find the site ...
