Collect Java version - Inventory - Extension Attribute

Works! Thanks Sean!

I'm running the below script as an extension attribute, but for machines that don't have java installed, they get that blasted popup in LION asking them to install java. Any ideas on how I can check the version on a client without java and if it's null do not prompt to install.

#!/bin/sh

#Redirecting complete output of java -version to tmp.txt file
java -version >tmp.txt 2>&1

#Getting current version from the tmp.txt file
VERSION=cat tmp.txt | grep "java version" | awk '{ print substr($3, 2, length($3)-2); }'

if [[ -z "$VERSION" ]]
then echo "<result>" "java not installed" "</result>"
else echo "<result>" "java" $VERSION "</result>"
fi

rm tmp.txt

After borrowing your version extraction line, I think I've got a way to bypass the pop-up in lion. I need to do a little more testing, but see if this works for you:

EDIT:

The following seems to be working for us as an extension attribute:

#!/bin/bash

#Check if java_home is defined
javaHome=/usr/libexec/java_home 2> /dev/null;

if [ ! -z $javaHome ]
then vers=java -version 2>&1 | grep "java version" | awk '{print substr($3,2,length($3)-2);}' echo "<result>$vers</result>"
else echo "<result>Not Installed</result>"
fi

@kevindigg, that EA is working great, thanks for the contribution.

i'm using this:

#!/bin/bash
echo "<result>`/usr/bin/java -version 2>&1 > /dev/null | awk '/version/ {gsub(/[""]/,""); print $NF}'`</result>"

Is Kevin's EA still working for folks? I have done a manual test via terminal but wanted to get confirmation before this is deployed to production machines.
Thanks for any feedback!

Our's looks like this, which just pulls the short version string, and not all that other info-

#!/bin/sh

if [[ -e /Library/Java/Home ]]; then
    echo "<result>$(java -version 2>&1 | awk '/version/{print $3}' | sed 's/"//g')</result>"
        else
    echo "<result>Java not installed</result>"
fi

In testing, it does not prompt 10.7 or 10.8 Macs with no Java installed to install it.

Kevin's looks like it works fine as well. Many ways to skin the same cat.

Great solutions!

How do we get the Extension Attribute to report "No" if Java is not installed?

We are testing SEP12.1 and so far so good...except that it requires Java to be installed. Ironic, no? :)

@Don

You thought so too? :-)

@ Don, see the one I posted above. In the if/then conditional I echo back "Java not installed" if the "/Library/Java/Home" directory is not found. You can change the echo to "No" and get the same result.
That's only one example. I'm sure there are several approaches that will all work.

@mm2270 I must have scrolled right past that! :(

Thanks!

nm. :)

not sure I get it: i created a new extension attribute in inventory preferences. selected input type populated by script. when i try to run an inventory report using it, it's asking for to match criteria that i guess I don't know. how is this supposed to work? sorry for noob question. thanks.

If you can post your Extension Attribute you might get some responses. :)

jamfnation user rtrouton has a funky script that I've adapted for use. You can find his original script at http://derflounder.wordpress.com/2012/10/31/casper-extension-attribute-scripts-to-report-java-browser-plug-in-info/

This is another alternate post that gives a very similar solution to what we're using.
https://jamfnation.jamfsoftware.com/discussion.html?id=5641#respond

I run the script that some others have implemented as well that franton is using.
I populate this by Script and the date type is String.

#!/bin/bash # Christoph von Gabler-Sahm (email-redacted) # Version 1.0 # checks installed version of Java Applet Plugin # returns values like "Not installed", "JavaInstallOnDemand: 14.5.0", "JavaJDK16: 14.5.0" or "Java 7 Update 09" PLUGINPATH="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin" # Plugin version S_VERSION=$( /usr/bin/defaults read "${PLUGINPATH}/Contents/Info" CFBundleShortVersionString 2>/dev/null ) # JavaInstallOnDemand or empty S_PROJECT=$( /usr/bin/defaults read "${PLUGINPATH}/Contents/version" ProjectName 2>/dev/null ) if [[ -e "${PLUGINPATH}" ]]; then if [[ "${S_PROJECT}" == "" ]]; then EA_RESULT="${S_VERSION}" else EA_RESULT="${S_PROJECT}: ${S_VERSION}" fi else EA_RESULT="Not installed" fi echo "<result>${EA_RESULT}</result>"

The Java Version is not shown.
But I can retrieve the vendor information with the script from derflounder...

OK. I have scripts running for version checking and vendor info, yet I need help with the results. In my office I have a mix of 10.6, 10.7, and 10.8 machines which are currently in the process of moving all to 10.8.2/3 once I figure out Casper imaging... Anyway, I need help figuring out what the different results mean to easily tell which version is latest for the Mac versions as "JavaInstallOnDemand" doesn't reflect the ASUS versions...
OS | Vendor | Version
1. Mac OS X 10.8.2 | Apple | JavaInstallOnDemand: 14.5.0 (what is this?)
2. Mac OS X 10.6.8 | Apple | JavaInstallOnDemand: 13.9.0 (This is JavaForMacOSX10.6-12.0/Java for Mac OS X 10.6 Update 12)
5. Mac OS X 10.6.8 | Apple | JavaInstallOnDemand: 13.9.2 (This is JavaForMacOSX10.6-13.0/Java for Mac OS X 10.6 Update 13)
Is there a place that lists JavaInstallOnDemand versions as they relate to ASUS list?
Thanks for any assistance.

I don't know of a list, but here's what the following statuses correspond to:

10.7.x - 10.8.x | Apple | JavaInstallOnDemand: 14.5.0 - Corresponds to Java for OS X 2012-006
10.7.x - 10.8.x | Apple | JavaInstallOnDemand: 14.6.0 - Corresponds to Java for OS X 2013-001

So is Apple updating Java again or do I still need to go get Java SE Runtime Environment 7u15 from Oracle or both?
Thanks.

Depends, do you need Java running in a web browser on your 10.7 / 10.8 Macs? Apple's Java for OS X 2012-006 and Java for OS X 2013-001 both remove the Apple Java browser plug-in.

Apple's handing off Java to Oracle, so Oracle's Java 7 Update 15 installs a Java browser plug-in on Macs running 10.7.3 and higher.

I see that now. I RTFM here.

About Java for OS X 2013-001 This release updates the Apple-provided system Java SE 6 to version 1.6.0_41 and is for OS X versions 10.7 or later. This update uninstalls the Apple-provided Java applet plug-in from all web browsers. To use applets on a webpage, click on the region labeled "Missing plug-in" to go download the latest version of the Java applet plug-in from Oracle. This update also removes the Java Preferences application, which is no longer required to configure applet settings.

I don't want to hijack this thread any further so I'll start a new thread. Thanks for your help.

This is the script I use which I grabbed bits and pieces from other scripts and edited

#!/bin/bash

javaPluginPath="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin"
javaVendor=`/usr/bin/defaults read "${javaPluginPath}/Contents/Info" CFBundleIdentifier`

if [[ "$javaVendor" =~ "com.oracle.java." ]]; then
        vers=`/usr/bin/defaults read "${javaPluginPath}/Contents/Info" CFBundleVersion 2>/dev/null`

elif [[ "$javaVendor" =~ "com.apple.java." ]] && [[ -L /Library/Java/Home ]]; then
     vers=`java -version 2>&1 | grep "Runtime Environment" | awk '{print substr($6,1,length($6)-9);}'`        

else
     vers="Not Available"
fi

echo "<result>$vers</result>"

This will return (on OS X 10.8.2):

Java 6
Java Plug-In Version:1.6.0_35-b10-428

Java 7
Java Plug-In Version:1.7.15.03

We use this format so we can easily cross check with XProtect settings.

I use two scripts, one to pull the Java 6 version and another for the Java 7. This allows me to create a smart group and filter what machine needs to be upgraded.

I'm trying to get a report on Apple's Java version on the boxes, and I've used a few of the EAs on JN, but they all seem to report Java7 versions now. Anybody have an EA that will tell me which version of J6 is on a box?
