Re: set path for jdk.3
Hello Liuchao: You need to set /etc/profile in order to run ( javac and java) from anywhere in your filesystem. In order to accomplish this, go to the directory /etc. Then look for the file pprofile. Also, use a text editor such as emacs or vi the edit this file. In this file you are going to see a line that looks like: PATH="$PATH:/usr/X11R6/bin" NOTE: your path might look different from this. Anyway, you should put /usr/java/jdk1.3 in your path. Your new PATH should look like this PATH="$PATH:/usr/X11R6/bin:/usr/java/jdk1.3/bin" save this file and reboot your system. If you need more help you can email me.

Re: ask for path
You can either set the path in the system boot up script or better still if you set it in your profile file. In linux your profile files will be in your home directory for instane if your login userid is liuchao, then your home directory will be /home/liuchao. look for profiles by typing ls -a at command prompt. this will give you a list all files including the hidden ones. edit either one of the files depending on what shell are you in. set the environment variable and path there. This way each time you login all the commands from /usr/java/jdk1.3/bin/ will be available for you automatically. Hope this helps.

Change /etc/profile if you want java available by default for all users of the system. Otherwise, you should change only the personal profile of specific user accounts. The name varies with the user's shell, common locations are .bash_profile and .profile. > Your new PATH should look like this > > PATH="$PATH:/usr/X11R6/bin:/usr/java/jdk1.3/bin" > > save this file and reboot your system. A reboot is not necessary. One need only logout and login, or simply source the profile. -- Joi EllisSoftware Engineer Aravox Technologies [EMAIL PROTECTED], [EMAIL PROTECTED] No matter what we think of Linux versus FreeBSD, etc., the one thing I really like about Linux is that it has Microsoft worried.

Re: ask for path
Since you're using linux, I'll give my examples assuming you're using bash as your primary shell. I've usually had the best luck setting environment variables in my .bashrc file and deleting my .bash_profile and then setting .bash_profile as a symlink to my .bashrc. To see what I'm talking about, check out the contents of your .bashrc and .bash_profile. $ cd $ cat .bashrc $ cat .bash_profile Be sure to copy anything important out of .bash_profile into .bashrc. Of course, if you just append the contents, it will save some time. $ cat .bash_profile >> .bashrc $ rm .bash_profile $ ln -s .bashrc .bash_profile Now, to actually set your environment, add the following lines to your .bashrc in your favorite editor. export JAVA_HOME=/usr/java/jdk1.3 export PATH=$PATH:$JAVA_HOME/bin Don't forget the 'export' in your script or the environment variable will not be set in child processes (such as scripts or programs you launch.)

This is NOT a good idea. .bashrc is run whenever a child shell is launched. IE every time a command you issue happens to be a shell script. .bashrc should be kept to the bare minimum, because the child is going to inherit most, if not all of its settings from the parent shell process anyway. > > $ cat .bash_profile >> .bashrc > $ rm .bash_profile > $ ln -s .bashrc .bash_profile No, no no.

Re: error on calling c function in java
If this is a JNI program you may get more verification that it was inside your own code or from the VM from running with -classic . The new 1.3.1 release will have better hotspot diagnostics than the cryptic message below. If you do 'man ascii' you can read off the file name below, (its in hex) the last 4 digits are the line number. ie os_linux.cpp 1468 There have been some bugs in relation to null arguments with JNI which I would guess can be coded around for now regards calvin Joi Ellis wrote: > > On 9 Apr 2001, Zhihong Pan wrote: > > > When I call c function in my java application, I got the following error message: > > # > > # HotSpot Virtual Machine Error, Unexpected Signal 11 > > # Please report this error at > > # http://java.sun.com/cgi-bin/bugreport.cgi > > # > > # Error ID: 4F533F4C494E55580E43505005BC > > # > > # Problematic Thread: prio=1 tid=0x804e500 nid=0x7062 runnable > > # > > 18Aborted > > Stick that long number into Bug Parade's search engin. > I remember looking for it a few weeks ago.

tempint=obj.StrInIntOut( "Hello");
tempstr=obj.IntInStrOut(34);
System.out.print(tempint);
