There is some problem with your Java runtime.

Thankx. i re ]installed the Java and everything is okay. i have some few questions;

1:how to stop user from registering by them selfs
2:how to customize the logo.
3:why can you get to choose a car icon when adding a device.

I run a VPS Centos. let me know more about these even if there some

Thank you.

1. Disable registration in server settings
2. Replace image files in the web folder
3. You cannot

whats the different between yours and http://traccar.litvak.su/features/
that looks very packed and feature rich

It does have more features than default UI at this point.

Openjdk works fine to me
$ java -version
java version "1.7.0_45"
OpenJDK Runtime Environment (fedora-2.4.3.0.fc18-x86_64 u45-b15)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

The problem is the libgconf-2.so.4 file (not exists) You should try to install it!

yum install GConf2

$ rpm -ql GConf2 | grep libgconf-2.so.4
/usr/lib64/libgconf-2.so.4

@charlymanja, you are a bit late with your comment. Java problem is already solved.

@Anton you are correct, it seems I don't read all messages, sorry!

So can you work on your version to be feature rich like his? or i can go ahead and install his Traccar-web. i need a solution asap and donation is for sure.

you are doing a good job.

I am working on adding more features. In the meanwhile I can install alternative UI if you are interested. Send me an email with details.

whats your email address.

You can find it on the Support page:

How do i upgrade to Traccar-web http://traccar.litvak.su/features/
