Ubuntu 14.04 loading JWS or accessing JSP exceptions workaround

A while ago, in Ubuntu 14.04, using Chrome to sign in to WebEx to prepare for an interview, I found that I couldn't get into an online interview. It was funny that the day before trying to get into WebEx was all right, but WebEx's online interview did not begin. Wait until the real interview starts, try to enter the interview room, only to find that unable to load normally.

The page always shows "Java not Found"

The same error occurred two days later when you were ready to log in to TopCoder.

Then enter java-version and Javac-version in the local terminal to display the version normally (JDK 1.7)

There is a page on the web that verifies that the Java Web App is working correctly http://www.java.com/en/download/installed.jsp

Using chrome under open JDK is inaccessible.

Search on the internet for some time after the discovery. The solution is: under Ubuntu, if you want to run Java Web apps normally. It is not possible to install the Oracle Jdk,open JDK.

For an introduction to these two versions, see Https://help.ubuntu.com/community/Java

The simple way to install an Oracle JDK is to add the PPA to the apt-get and then use the Apt-get install.

sudo add-apt-repository ppa:webupd8team/javasudo apt-get updatesudo apt-get install oracle-java8-installer

See http://www.webupd8.org/2012/09/install-oracle-java-8-in-ubuntu-via-ppa.html for details

Finally, do not use chrome, be sure to use Firefox,webex temporarily does not support Linux under the chrome.

But it's not all about him. After installing the oracal JDK, accessing http://www.java.com/en/download/installed.jsp under Chrome is still not working. It is expected that chrome itself is a problem.

In the Oracle JDK environment, using Firefox to access http://www.java.com/en/download/installed.jsp, you should see the following pages.

If you still can't get to WebEx at this point, it could be a security issue.

Control Panel opens the Oracle JDK installation path (typically/usr/lib/jvm/java-8-oracle/bin, with a slightly different version number). Add the Web site you want to visit to the exception list.
