rectangle below this paragraph with one line of text that says something like "Java Version 1.5.0_12 from Sun Microsystems Inc.":
problem: the Java Run-time Environment ("JRE") is installed on your computer, but it is disabled in your web browse, or you don't have a java plugin installed in your browser
1. To enable Java in your browser, click one of these links:
2. To install a java plugin in your browser
Fedora: yum install java-*-openjdk java-*-openjdk-plugin
You might also need to Clear your Web Browser Cache to get Java to work in your browser.

Firefox works with VoxForge Java applet on Linux
(see: How To Install Java on Ubuntu with Apt-Get)
install OpenJDK (Java on Ubuntu) and Icedtea (browser plugin)
$ sudo apt-get install default-jre
$ sudo apt-get install icedtea-7-plugin
(see: Java FAQ)
install OpenJDK (Java on Fedora) and Icedtea (browser plugin)
$ su -c "dnf install java-1.?.0-openjdk"
$ su -c "dnf install icedtea-web"
You need to follow the instructions on this page: Use the Java plugin to view interactive content on websites, which then point you to Oracle's Manual Installation and Registration of Java Plugin for Linux article for help installing or updating Java on your Linux system.
Basically, you need to install Oracle version of Java. Then create a link to the Java plugin file is included as part of that install in Mozill'a plugin directory, as follows:
1. go to firefox plugin directory:
$ cd ~/.mozilla/plugins
2. create link to the Java browser plugin:
for Intel-based computers:
$ ln -s /usr/java/latest/jre/lib/i386/libnpjp2.so .
or for AMD-based computers:
$ ln -s /usr/java/latest/jre/lib/amd64/libnpjp2.so .
3. restart firefox
The Java plug-in for web browsers used by the VoxForge applet relies on the NPAPI (Netscape Plug-in API) cross platform plugin architecture.
Starting with Windows Chrome Version
42, Google has added an additional step to configuring NPAPI based
plugins like Java to run:
(Note: Chrome NPAPI support was removed from the Linux platform starting with Chrome version 35)
You can still use: Firefox, Internet Explorer or Safari.
Update - Sept 15, 2015, from Google website:
Plugin-based content doesn't work on Chrome
To make browsing with Chrome safer, faster, and more stable, we stopped allowing NPAPI plugins on September 1, 2015.
Plugins that use NPAPI, including Silverlight, Java, and Unity, won’t work.
from the Oracle Java faq:
Starting with Chrome
version 35, NPAPI (Netscape Plug-in API) support was removed for the
Linux platform. For more information, see Chrome and NPAPI (blog.chromium.org).
Firefox is the recommended browser for Java on Linux.
From Slav' post: What does the removal of NPAPI plugin support mean to an end user?
If your browser is behind a proxy server, please set up your Java JRE as follows:
can julius be interfaced with visual studio?
The speechsubmission applet does not seem to work with newer versions of the OpenJDK (see this bug report [Bug 540962] [abrt] crash detected in java-1.6.0-openjdk-1:188.8.131.52-33.b16.fc12 ).
As a workaround, you will need to install Sun's Java:
The Java applet generated a security error for me: 'access denied (javax.sound.sampled.AudioPermission record)'.
Unfortunately I lacked more than five minutes to try and fix the issue, so gave up trying.
The message: "Browser has Java disabled" may be the result of Java and your browser plugin not being installed:
The java applet seems to behave just fine (recording and playback work) but when I upload the result, the "Uploading..." message is displayed and it never completes. I waited about 20 minutes. Suggest that you add a progress meter or some way to confirm that the upload is happening. Also suggest you add the capability to save the zip file locally so that the recordings are not lost and can be sent it manually.
I'm getting the error:
Line matching interface TargetDataLine supporting format PCM_SIGNED, 48000.0 Hz, 16 bit, mono, little-endian not supported.in the area where the waveform should appear, on "Java Version: 1.5.0_13 from Apple Computer, Inc."
This is almost the same error as this trac ticket: http://www.dev.voxforge.org/projects/Main/ticket/193
I have got
a studio quality USB microphone "Snowball" but when I try
to record my voice using the applet it records silence. I tested the
microphone in Audacity - it works (though I need to adjust the sample
rate) and my java seems to be good: java version "1.6.0_03".
might be wrong?
I am using Russian version of the aplet
my computer is Ubuntu 7.10, kernel 184.108.40.206-generic, GNOME 2.20.1,
Memory 2GB, CPU AMD X2 Dual Core BE-2400
According to every java testing site I have Java 1.7 properly installed, still I see only an empty grey box on the Troubleshooting page. (And can't find the applet in general.)
