Java in PATH but not found by applications?

Mark_667 · 02-01-2011, 11:24 AM

I'm setting up a RHEL 4 VM and have installed Oracle Java 1.6 from a bin file to /opt. I've added it into the PATH but when I try to run a installer that needs Java to run it says that it can't find a Java installation in my PATH but when I execute a which java I get the following:

Quote:

# which java
/usr/bin/which: no java in (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/opt/jre1.6.0_23/bin/java:/root/bin:$/opt/jre1.6.0_23/bin/:$)
#

Can anyone tell me what's going on here?

informing us as to what this " installer " is would help
rhel4 .? .0.1.2.3.4.5.6.7.8 or the CURRENT 4.9 ???
point what ???

rhel4 might not be supported by this program ( is is locked into 5 year old code after all)

also will the current java 1.6 even run on rhel4.0 ???

I would say show us with an ls -al exactly where java is please - also I may have just never seen it but whats with the "$" in your path? All you should need (if java is in /opt/jre1.6.0_23/bin) is /opt/jre1.6.0_23/bin in your path....

with Java, sometimes you have to set the "Java_Home" variable instead.

/root/.bash_profile

Quote:

export JAVA_HOME=/usr/java

#uname -ar
Linux <hostname> 2.6.9-42.ELsmp #1 SMP <date> i686 i686 i386 GNU/Linux
#

The installer is InstallAnywhere.

According to this:
http://www.java.com/en/download/help/6000011000.xml
Java 6 is supported.

# ls /opt/jre1.6.0_23/
bin javaws man README Welcome.html
COPYRIGHT lib plugin THIRDPARTYLICENSEREADME.txt
#
Don't know what you want this for, but there you go.

Also, I tried setting JAVA_HOME to /opt/jre1.6.0_23 where I instyalled it and logged off and on again but it made no difference.

What I really wanted was an ls of /opt/jre1.6.0_23/bin but thats cool - I just want to actually see the java executable in case it is a link that is not working as many times "java" is just a link to the current version - can you run /opt/jre1.6.0_23/bin/java? Is it even there? This is at least the starting point of finding the problem - I mean at this point we need to figure out if it is a problem with the way java was installed or if it is a path issue or something else entirely.

You need to remove the '/opt/jre1.6.0_23/bin/java' entry and remove the '$' from the last entry for starters.

John VV · 02-02-2011, 03:48 PM

what is this " installer " that can not find the different install of java .
Different than the base default .

that program might be the problem.

The program is the problem, it's Oracle installer.
szboardstretcher is correct

with Java, sometimes you have to set the "Java_Home" variable instead.

/root/.bash_profile

Yes, just executing that command gives me a usage page for it.

Done, I also set JAVA_HOME while I was in there, I logged out and in again for the PATH changes to take affect but it didn't make any difference.
