sh: java: not found

[Roslyn Faicol]

Could someone help me on this.

I am trying to check what version of java is installed in our box.

I tried to check it first using the ff command.
# swlist -l product | grep -i java

and got this.
ISEE-Java A.01.31.12 RST Java Runtime13-13109
Java-PlugIn1-2 1.2.2.15.00 Plug-In for Java 2
Java2RTE_base 1.2.2.15.00 Java 2 RTE (700/800), PA1.1 Portable

Jre13 1.3.1.13.01 Java2 1.3 RTE 1.3
Jre14 1.4.2.04.00 Java2 1.4 RTE

However, when i tried accessing the command : #opt/java1.3/bin/java -version
sh: java: not found

Is there something wrong with my command?

run ll -d /opt/java* and find where is your java installed.

Hi Roslyn,
you may be missing a "/" before opt ?
/opt/java1.3/bin/java -version

You could also try to verify the path with:
which java

[Roslyn Faicol]

I run the command :
# ll -d /opt/java*
here's the result.

dr-xr-xr-x 4 bin bin 96 Jun 3 2005 /opt/java1.2
dr-xr-xr-x 7 bin bin 8192 Jun 3 2005 /opt/java1.3
dr-xr-xr-x 8 bin bin 8192 Jun 3 2005 /opt/java1.4

Hi Peter,

Thanks, you are correct I did miss the /. However, there are two java installed in the system,how would I know which is currently being used?

java version "1.3.1.13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1.13-040210-15:41)
Java HotSpot(TM) Server VM (build 1.3.1 1.3.1.13-_10_feb_2004_17_15 PA2.0, mixed
mode)
svprfaic@unphod54:/>/opt/java1.4/bin/java -version
java version "1.4.2.04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2.04-040628-18:09)
Java HotSpot(TM) Server VM (build 1.4.2 1.4.2.04-040628-20:03-PA_RISC2.0 PA2.0 (
aCC_AP), mixed mode)

Thanks

Hi,
most systems create a link from whichever version they want to use to /opt/java/bin, as most installs use this location.

However, if you prefer you can include your chosen java location in $PATH:
First check existsing path value:
echo $PATH | grep -i java
If not set, you can add with:
export PATH=$PATH:/opt/java1.3/bin

The export command could also be added to your .profile script in your home directory.

If your "which java" command did not return the location of a java directory, you environment does not include a valid java location.
See "man which"

Thanks for your patience... I understand everything clearly.
