Make sure you have the latest Java installed on your computer for your web browser.  The official download location is:  Please read the prompts, so you are not installing extra stuff you don't really need (like toolbars).

JRE stands for Java Runtime Environment which is Java.

If you are having issues, try each of these ideas individually in the order listed

1.  Add '' to your Compatibility View Settings (slide 19 of this guide)

also shown on


2.  Use the Internet Explorer executable located at: "C:\Program Files\Internet Explorer\iexplore.exe" right-click it & select Run as administrator.  You may still get the same "Java Plug-ins incompatible message" warning, but it will allow you to enable the plug-in and access DTS.


3. If you are still having issues, you can uncheck "Enable Enhanced Protected Mode"

by clicking Tools, Internet Options, Advanced (tab)

4.  Some users have had to reduce the security level of Java

NOTE:  This option is only available with Java versions 7-71 and earlier.  You cannot make this change with newer versions of Java.

Video from DBSign on how to set up DTS on Mavericks OS X 10.9.x (same instructions will work for Yosemite 10.10.x & El Capitan 10.11.x)

Information below borrowed from:

If you have Safari 6.1 or above on your Mac, there are a few additional steps to configuring Safari for DBsign.  The new security features in Safari prevent DBsign from reading and writing to its configuration files without explicit permissions.

In order to grant the necessary permissions to web sites running DBsign, you must edit Safari's security preferences.

El Capitan 10.11.x- From the "Safari" menu, choose "Preferences" and then go to the "Security" (tab).  Here, you will see a section titled "Internet plug-ins" with a button that says "Plug-in Settings..." .  When you click on the button, you will see an image similar to the one below:

Yosemite 10.10.x- From the "Safari" menu, choose "Preferences" and then go to the "Security" (tab).  Here, you will see a section titled "Internet plug-ins" with a button that says "Website settings..." .  When you click on the button, you will see an image similar to the one below:

Mavericks 10.9.x- From the "Safari" menu, choose "Preferences" and then go to the "Security" (tab).  Here, you will see a button that says "Manage website settings...".  When you click on the button, you will see an image similar to the one below:

Select Java

Safari Prefs image

Locate each web site that uses DBsign in the list (DBsign's site, the Defense Travel System site, etc). In the drop down box to the right of the web site address, choose "Run in Unsafe mode".  This gives DBsign all the permissions it needs to run properly.  DO NOT change this setting for web sites you do not explicitly trust.

Run in UnSafe Mode

Once you've selected Run in Unsafe Mode, select Trust

Prefs Messae

If you do not see the proper web site in the list, you need to visit that site and attempt to use DBsign.  You will most likely receive a DBsign error, but the web site should now be included in this list. You should be able to change the settings now.

How to I test DBsign?

DBsign has a test page located here:

If Java is working, and DBsign is able to load, you will see a page that looks like this:

dbsign_test image

If the page just "sits" there with a "Loading DBsign..." message, then Java is probably not working properly.  See the section above for information regarding checking your Java version.

If you get an error message when loading this page, please contact DBsign for help.

If the page loads properly, you should be able to click on the "sign" button in the middle of the page. This will tell DBsign to generate a digital signature using one of the certificates on your computer or smart card.  If no error occurs, your page will look like this (with signature information filled out):

dbsign_test_signed image

If you get an error message when attempting to sign, please contact DBsign for help.


NOTE:  If you are having problems logging onto all CAC websites (including DTS) [and you can see your name entry between the words: keychain and login in Keychain access] there is a good chance you have blocked your CAC.  Unfortunately there is no way to verify a blocked CAC on a Mac.  It can be checked via ActivClient on a Windows computer (or virtual machine).  If your CAC is in fact blocked, your only option is to visit an ID card office to get the card unblocked.

Mac 10.7.x and 10.8.x Users

Read information from DBSign regarding using DTS with your Mac.

Apple removed Java from the OS, so, using DTS now requires additional steps

Every time Apple updates to a new version of their OS, you'll need to update your Java again from:

Run DBSign Test Utility

You can verify which version of Java you currently have installed by visiting:

If you have have the correct Java installed, please test it by following this link:  If problems still exist with DTS, follow these instructions from DBSign


If you encounter the following error....  Read below

DBSign Error message

You must disable OCSP checking for Java applets first

HERE'S HOW:  Open the Java Control Panel (this is the "Java" icon in OS X System Preferences). Open the Advanced (tab). Find the section labeled Security and uncheck the box labeled Enable online certificate validation. See below.

According to the bug reports this issue has been fixed in an upcoming Java patch release, but we do not know when that will be publicly available.


Question 1:  I'm seeing a blank page after logging into DTS and trying to navigate to my authorizations or vouchers.  How do I fix this?

Answer 1-1 Click the word Safari, Select Security, uncheck the box for Block pop-up windows. 


NOTE:  For 64 bit Macs You "may" need to run Safari in 32 bit mode vs. 64 bit.  Here's how:  Go to Applications in Finder, right click get info on Safari.  Check the box Open in 32bit mode, then launch Safari.

When will I be able to use DTS on an iPad or iPhone?

On 7 July 2014, Thursby Software released PKard for iOS version 2.1.4.  This version allows access to Defense Travel System (DTS) on iPad ONLY

 fogflagbar image

Mac 10.6.x and below

Run DBSign Test Utility

1) Verify Java is installed in the Installed Software tab of the Software Update pane of System Preferences (or Apple menu > System Preferences).

2) In 10.6.8, Java preferences are not in System Preferences pane but are instead a separate app (Applications > Utilities > Java Preferences), and DTS won't download the DBsign applet until you check the "Enable applet plug-in and Web Start applications" checkbox at the top of the General tab in the Java Preferences app.

3) In Safari, enable pop-up menus by *unchecking* the "Safari > Block Pop-Up Windows" menu item.
