#4392 — Jruby -v failing with possible Java version issue

[Note:  parts of this message were removed to make it a legal post.]

Hello team,

I installed jruby 1.6.1, as fully described below.
When I run the *jruby -v* command, it fails. Please see output at the end of
this post.

Downloaded file:
 *jruby-bin-1.6.1.tar*

When I verify Java on the Oracle site, I get the following:

        Your Java is Working
        Java update available

        Your Java configuration is as follows:

I dug into this a few months ago.  It looks like the IBM implementation of 
Java doesn't support the "-client" command line switch.  I wound up 
switching to a different version of Java.

It's not what I know that counts.
It's what I can remember in time to use.

I'm not sure if the IBM Java supports all the flags which Sun/Oracle java 
supports.

Your path looks really weird here.

Also, I think that jruby requires the jdk, not the jre.

try a

which java

and a

java -version

But I do believe there's an issue with IBM's java version.

Hi,

This is the output of the commands suggested:

1.4.2 won't work.  You need java 1.6.  FWiW, Java 1.4 was sunsetted a 
number of years ago.  1.5 was sunset in 2009, I believe.

And IBM Java won't work.

But I have 1.6, I installed it.
If I go to the Oracle site and run their applet to verify the java version,
I get the following:

When I verify Java on the Oracle site, I get the following:

        Your Java is Working

Perhaps, like you said, I have to switch from IBM to Oracle version.
I don't want to remove the IBM version since it might be used by some
application on the server, but I am wondering if I can have multiple Java
versions from different vendors.

Thank you

Yes, you can. Just make sure to install OpenJRE/OpenJDK to its own
directory, and specify this version whenever you want to use JRuby.

Then, you can test if the Oracle version makes any of your other apps
fail, before migrating over (if you want to).

You should also post JRuby specific questions one mailinglist over on
JRuby-user. There's the experts who can help you with both Java and
JRuby issues. :)

That may be the case, however, when you ran java -version, it says 1.4.2

So that's the one which is first in your path.

How are you verifying this????  Via a browser or an applet?  That does not 
necessarily count.

Yes, you can.  It is controlled by your path.  Just make sure that the 
version you want to use comes first in the path.

OK gents, I installed Java 1.6 and pointed to it via the JAVA_HOME
environmental variable. It looks like it worked.

jruby -v
jruby 1.6.1 (ruby-1.8.7-p330) (2011-04-12 85838f6) (Java HotSpot(TM) 64-Bit
Server VM 1.6.0_25) [linux-amd64-java]

Just saw this thread today...

If you (or anyone else) need to use IBM JDK and get that "-client"
error, you can pass "--noclient" to JRuby to disable that flag.
Normally we pass -client to the JVM because on Hotspot/OpenJDK (by far
the most widely used) it helps startup time a lot. Unfortunately it's
not a standard flag.

Charlie,

Thank you for the info. I am sure it will become useful.

Thanks again,
