Click the orange launch button to start the Replicator and download the complete mindprod.com website, or update your local downloaded copy. To learn in detail how the Replicator
works, read the manual.
On 2012-05-13 I released a new version 11.3 of the Replicator.
You may need to manually delete the old version
from your javaws.exe control panel before the new
one will work.

Install or Repair JWS
- Often problems can be fixed simply by clicking the reload button on your browser.
- This signed Java Web Start application needs 32-bit (not 64-bit) Java 1.6 or later.
For best results use the older 1.7.0_17 not the latest buggy 1.7.0_21.
In the Java Control Panel, configure medium security to allow vanilla unsigned applets to run.
- You also need a recent browser.
- It works under any operating system that supports Java e.g. W2K/XP/W2003/Vista/W2008/W7-32/W7-64/W8-32/W8-64/Linux/LinuxARM/LinuxX86/LinuxX64/Ubuntu/Solaris/SolarisSPARC/SolarisSPARC64/SolarisX86/SolarisX64/OSX
- You should see the Java Web Start above looking much like this screenshot. If you don’t, the following hints should help you get it working:
- For this Java Web Start to work, you must click grant/accept to give it permission to write the downloaded files to your hard disk.
If you refuse to grant permission, the program may crash with an inscrutable stack dump on the console complaining about AccessController.checkPermission.
- Optionally, you may permanently install the Canadian Mind Products code-signing certificate so you don’t have to grant each time.
- If the above Java Web Start appears to freeze-up, click Alt-Esc repeatedly to check for any buried permission dialog box.
- If you have certificate troubles, check the installed certificates and remove or update any obsolete or suspected defective certificates. The only certificate used by this program is mindprodcert2013dsa.cer.
- Even if JWS (Java Web Start) complains that the certificate used to sign this application is “invalid”, please click grant/accept anyway.
- If the above Java Web Start does not work, or if it fails to automatically install the latest versions, try running:
on the command line, then click show applications and delete any of the unworking or obsolete applications. Then click show resources and delete any of the unworking or obsolete resources. Then try launching the application again.
- If the above Java Web Start does not work, or if it fails to automatically install the latest versions, try uninstalling the JWS application in the control panel or uninstall it with:
on the command line, and try launching the application again.
- If reinstalling does not work, especially if JWS appears to be using an obsolete *.jnlp file stuck in cache, try bulk uninstalling all JWS apps with:
on the command line, and try launching the application again.
- If the error message says “program not found” the problem is likely a damaged association between *.jnlp files and the javaws.exe program. To learn how to repair the association, click the Repair button below.
- For Firefox, select open with: Java(TM) web start launcher.
- To ensure your Java is up to date, check with Wassup. First, download it and run it as an application independent of your browser, then run it online as an Applet to add the complication of your browser.
- If the above Java Web Start does not work, check the Java console for error messages.
- If the above Java Web Start does not work, you might have better luck with the downloadable version available below.
- If you are using Mac OS X and would like an improved Look and Feel, download the QuaQua look & feel from randelshofer.ch/quaqua. UnZip the contained quaqua.jar and install it in ~/Library/Java/Extensions or one of the other ext dirs.
- If you are using Microsoft Internet Explorer 7, 8 or 9, try another browser. Seriously. Microsoft has taken great pains, over and over, to screw up Java and every other multi-platform standardisation.
- If you are using Microsoft Internet Explorer 7, 8 or 9, you must click to allow blocked content permission for Active X to run. This also gives permission to Java to run. Click the Information bar, and then click Allow blocked content. Unfortunately, this also allows dangerous ActiveX code to run. However, you must do this in order to get access to perfectly-safe Java Applets running in a sandbox. This is part of Microsoft’s war on Java. Don’t put up with it! Use a different browser.
- If you are using Microsoft Internet Explorer 9, makes sure the Java Plug-In SSV helper add-in is installed and enabled.
If it is not, try reinstalling the Java JRE.
- If you have Windows 7 64-bit
and Internet Explorer 64-bit,
in theory you can use 64-bit Java,
but I never been able to get it to work.
- Try upgrading to a more recent version of your browser, or try a different browser e.g. Firefox, SeaMonkey, Safari or Avant.
- If you still can’t get the program working click HELP for more detail.
- If you can’t get the above Java Web Start working after trying the advice above and from the HELP button below, have bugs to report or ideas to improve the program or its documentation, please send me an email at.
You can safely abort at any time. The Replicator will pick up where you left off the next time you download. If
the Replicator fails, try again in half an hour or so. There may have been a glitch in uploading the files.
To read more about how the Replicator works, read the Replicator Manual.
The download covers definitions of Java terminology, essays on various Java related topics and pointers to where
you can get more information about Java related problems. It also covers the entire mindprod.com website which discusses political, environmental and religious issues. It includes the
gay glossary, the Computer Hardware Buyers’ Glossary, all the sound and image files.
I update the website many times a day and post the changes to the Replicator. You can stay as up to date as you
want. You can run the Replicator to update your local mirror copy as frequently or as infrequently as you like.
Whenever you run the Replicator, you will get just the net changes since your last visit.
You must run the Replicator every time you want to get the recent updates. It will not automatically schedule
itself. After the first time, it will be very quick unless there has been a massive update to all the headers and
Google Desktop will then let you find anything in the
local mirror with indexes that are only seconds out of date.
The Replicator downloads the website is in ~1 MB zipped chunks, and automatically unpacks and decompresses them.
On subsequent visits, The Replicator automatically downloads just new zips containing files that have net changed
since your last visit.
If you have trouble with the download button, try starting Java Web Start manually with:
If the Replicator just sits there and does nothing, and you are using version 1.5.0
(build 1.5.0_07-b03). Fedora Core 5 Linux, if you upgrade to Java version 1.6 it will work.
If you have trouble, email me at
or arrange a phone call and I will talk you through the setup. This software has been working fine
It will take a long time (still under 10 minutes for ADSL (Asymmetric Digital Subscriber Line technology)) for your first download (~85 MB broken into 1 MB
pieces) but subsequent ones should be rapid.
You can safely abort at any time. The Replicator will automatically pick up where you left off the next time you
Why download with the Replicator instead of browse online?
- If mindprod.com goes down temporarily or permanently, you will still have a
- You can browse your local copy more quickly than the web copy. You will find the Google AdSense ads will drive
you nuts offline trying to fetch an ad from the unreachable Google server. I have not yet figured out how to
suppress the ads automatically when you are viewing offline. However, you can suppress them by turning off
- You can use your local search tools to find things.
- You are providing yet another level of backup to foil those who would destroy the mindprod.com site. Because the material is constantly changing, and won’t stay up to date,
please don’t repost pages from my website unless my site disappears completely. The web is littered with
out-of-date copies of my material that people stumble on. If you want to host a complete mirror site that I will
keep up to the minute, please send me an email at
so we can work out the details.
- With the Replicator, your local copy can now be just as up-to-date at the uncompressed website HTML (Hypertext Markup Language) with very
See the manual to learn how the Replicator works and how you might use it for
your own websites or bulk file distribution problems.
To get best performance from the Replicator, you should tweak/tune/configure/adjust your
TCP/IP downloading. This will speed up all your internet
connections and downloads, not just the Replicator, perhaps by as much as 100 times.
Try any or all of these tuning tools to see which works best for you: TCP Optimizer, TweakMaster
Beware. The Google web accelerator proxy drastically slows down Java Web start unless you
configure jawaws.exe to use a direct network connection.
Because of a limit inherited from MSDOS, and the PKZIP format that the Replicator uses to distribute files, the
reconstituted files will have timestamps accurate only to within 2 seconds of the original. The timestamps reflect
local time on the source, not UTC (Coordinated Universal Time/Temps Universel Coordonné) time. This will cause no problems with the mindprod.com files since the timestamps
are only used to give you an idea of when a file was last changed.
