J2SDK install problem on Mandrake 9.1


hi-

Quite new to linux, having left the dark side recently.

My problem:

trying to install the file "j2sdk-1_4_2-nb-3_5_1-bin-linux.bin", the java packagfe that includes net beans.

i get an error telling me to use the -concole flag, since for some reason it will not work graphically. fine, whatever. so when i run it using ./j2sdk-1_4_2-nb-3_5_1-bin-linux.bin -console, i get an error saying:

"java.io.IOException: usr/bin/id: cannot execute at...." and a zillion lines following this.


i have downloaded the .bin file into home/me/j2sdk FWIW, and am running the install from there.

i have tried to set my PATH settings appropriately, but i really don't know what i am doung, yet. ugh.

PATH=$PATH:/home/me/j2sdk/bin
JAVA_HOME=/home/me/j2sdk/bin
export PATH
export JAVA_HOME

any suggestions? :-)



thank you,

jxl

All you've to do to get Java running is to... install Java SDK ( a good place is /usr/local/j2sdk1.4 <your_version>)

when done, type java -version at the console. If it returns something like:

bash-2.05b$ java -version
java version "1.4.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_02-b06)
Java HotSpot(TM) Client VM (build 1.4.1_02-b06, mixed mode)

Then you are good . To compile java code, there're two ways of doing it. The first one is using javaSDK. The compiler for it is javac, located somewhere at /usr/local/j2sdk <your_version>/javac. You could instead of setting the PATH, using a symbolic link to it:

ln -s /usr/local/j2sdk <your_version>/javac /usr/bin/javac

Now you can compile programs with javac <YourProg.java>, and run them with java YourProg.

The other way is installing gcj. A gcc extension for java. It is a very good replacement for Sun's kit, if you cannot get it to work . To compile a program, type:

gcj -C <YourProg.java>

A little offtopic, but you might want to give this good java IDE a shot:

http://drjava.sourceforge.net/

As a Java student myself, I'm in love with that little toy

Good luck!

hmmmm... is it the installation failing? Lemme see

hmmmmmm. I've got the package called j2sdk-1_4_2_03-linux-i586.bin. Then I've installed it with:

sh j2sdk-1_4_2_03-linux-i586.bin

The installation on Linux is not graphical as it Windows, but it's just as simple . You've said that you are trying to install "j2sdk-1_4_2-nb-3_5_1-bin-linux.bin". Is that the name of the file or the command you are issuing? Because it was pretty different for me Both command to install and package name (as you see above)

yeah, the filename is different than yours, *i think*it is because this one is the cobundle with net beans...

when i try to install using ./<filename>

i first get:

Installation Wizard

Initializing InstallShield Wizard...

Preparing Java(tm) Virtual Machine...

......................
......................
......................
......................
......................
java.io.IOException: /usr/bin/id:cannot execute
at java.lang.UNIXProcess.<init> (unknown source)
at java.lang.Runtime.execInternal (Native Method)

etc..etc..

any idea why this is hasppening?

thanks for the help so far!

Mandrake 9.1 is more of an RPM based distro, Get the RPM version of java and that will solve your problem. There is also an RPM version of Flash. You can find them both by googleing at
www.google.com/linux hope this helps
