I have installed Java on Mandrake 10.1
The file name I downloaded was something jre-1_5_0_01-i586_rpm.bin
I logged in as root and created a directory java in usr/local/
I extracted the files and I found the directory java/jre-1.5.0_01 under /usr
I set the path using
export JAVA_HOME=/usr/java/jre1.5.0_01
export PATH=$PATH:JAVA_HOME/bin:

When I run the command >javac
It says bashc: javac not found

Then I put
>export CLASSPATH=$CLASSPATH:.

Still I am not able to run javac command.

Where have I gone wrong ?
I added the path /usr/java/jre1.5.0_01/bin to the PATH variable in profile file.

Still I am not able to run java command from any other directory other than /usr/java/jre1.5.0_01/bin direcrtory

Also I see that there is no javac file in the bin directory.

Can somebody please help and tell me exactly what do I do after installing Java ?

hi there

u need to add the path to

/etc/ld.so.conf

and then run

ldconfig

also
please post ur questions in appropriate forum ,not in this forum

regards

Thanks for quick reply.

Sorry, I did not know that there are different forums on various subject. Can you tell me which is the appropriate forum ?

Can you please tell me what is this file ld.so.conf ?

You mean I need to type the following lines

export JAVA_HOME=/usr/java/jre1.5.0_01
export PATH=$PATH:JAVA_HOME/bin:
export CLASSPATH=$CLASSPATH:.

in ld.so.conf and not in .profile file so that all users can run java ?

try adding this

/usr/java/jre1.5.0_01

to /etc/ld.so.conf

and run

ldconfig

and for problems like these u can post them in the linux-newbie,software section

regards

It seems to me that you have downloaded the runtime, only. If you want to use the compiler, you should download a full j2sdk and install that. In my installation (which is 1.4.2), in the jre/bin subfolder of the installed structure, there are no javac command, only the java command which is the runtime, so I guess that your requirement to use the compiler also requires you to install the SDK.

When installed (i guess you just have to gunzip/untar the thing you download), you should set JAVA_HOME to the <sdk_install_folder> and update your path to point to <sdk_install_folder>/bin.

Be sure to place the definition of the bin folder early enough in the path, as some Linx distros comes with a default java runtime.

To review that everything is ok, you should do

$ which java
/usr/local/bin/java (my location)
-and-

$which javac
/usr/local/bin/javac (my location)

The try to run the VM:

$ java -version
java version "1.4.2_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_07-b05)
Java HotSpot(TM) Client VM (build 1.4.2_07-b05, mixed mode)

in order to verify that the version you are running is the same as the one you installed (untarred).
The version of your java installation should read 1.5.0_01
