When installing JDK in my machines (Windows 7), I do the following.
Then I synchronise that folder in all my machines so I keep it updated (with unlimited cryptography stuff, jssecacerts, java.policy
, endorsed libraries, etc).
BUT this has one big caveat, when Chrome needs to use load a page that uses Java, it thinks Java is not installed and wants to install it. I don't want to install it as it would mess with my 'hand-installed' JDK.
So is there a way to configure Chrome so it uses the JDK in my disk? I have both JDK 32-bit and JDK 64-bit, so that is not a problem (I guess I would need to use the 32-bit one with Chrome).
I found a question in the Chrome project, How do I have the Chrome Java plugin reference an existing JDK without reinstalling Java?, but no replies so far...
UPDATE: for Ubuntu, see Kalyan's answer
UPDATE: I still continue to use this approach successfully, last time with 1.7.0_21 on win7
UPDATE for 1.7.45: the path in the windows registry now is [HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins]
This question is related to
java
google-chrome
plugins
Starting with Version 42, released April 14, 2015, Chrome blocks all NPAPI plugins, including Java. Until September 2015 there will be a way around this, by going to chrome://flags/#enable-npapi
and clicking on Enable
. After that, you will have to use the IE tab extension to run the Direct-X version of the Java plugin.
On Windows 7 64-bit, I added the registry entry using the following script:
@echo off
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin"
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin" /v "Description" /t REG_SZ /d "Oracle Next Generation Java Plug-In"
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin" /v "GeckoVersion" /t REG_SZ /d "1.9"
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin" /v "Path" /t REG_SZ /d "C:\Oracle\jdev11123\jdk160_24\jre\bin\new_plugin\npjp2.dll"
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin" /v "ProductName" /t REG_SZ /d "Oracle Java Plug-In"
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin" /v "Vendor" /t REG_SZ /d "Oracle Corp."
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin" /v "Version" /t REG_SZ /d "10.3.1"
Note that you will have to change the Path
.
I came across a similar issue but instead of changing the regedit I decided to change the Chrome settings
Try the following steps
chrome://plugins/
+ Details
(top right corner) to expand all the plugin details.Java
and click on Disable
for the path(s) that you don't want to be used.You might have to restart the browser to see the changes. This also assumes that the Java that you have enabled is the latest Java.
Hope this helps
I use Windows 7 Professional 64-bit and have both the 32-bit and 64-bit Java 7u9 jre's installed. Chrome refused to work until I deleted the following registry key.
HKEY_LOCAL_MACHINE/Software/MozillaPlugins/@java.com/DTPlugin,version=10.9.2
Then I refreshed Chrome and the Applet loaded with a Warning that the plugin was out of date. I seleted "Run this time" and everything worked as expected.
I looked around for a solution to this for a while. It appears that the JDK doesn't have the Mozilla plugins (which is what Chrome uses) in it's installation. It is only in the JRE installation. There are a couple of DLLs that make up the plugin and they all start with np*
I'm on Windows 7 64 bit and couldn't understand if I can manually enable JRE8 64 bit for Chrome. Turned out that my problem was that Java plugin DLL is 64 bit which wouldn't work in 32 bit Chrome. Therefore you need to install x86 version of JRE. Below are Windows registry settings you need to create

On Ubuntu, You can follow these steps to resolve the issue:
$HOME/.mozilla
, if it doesn't exist alreadyCreate a symlink to libnpjp2.so inside this directory using this command:
ln -s $JAVA_HOME/jre/lib/i386/libnpjp2.so $MOZILLA_HOME/plugins
-or-
ln -s $JAVA_HOME/jre/lib/amd64/libnpjp2.so $MOZILLA_HOME/plugins
depending on whether you're using a 32 or 64 bit JVM installation. Moreover, $JAVA_HOME is the location of your JVM installation.
