# Using Java Console
 
When ActiveX/Java Uploader is utilized in non-Internet Explorer browsers (Firefox, Safari, and etc.), it uses java applet as a client-side application. Java applets provide a feature which is very useful when it is necessary to get additional information about some problem: special console where the applet can trace various debug information. This topic describes how to get information from the Java console.

### Java Console Usage
 
After you open Java console, use ActiveX/Java Uploader to reproduce the problem. Debug information will be automatically dumped into the console.
 
You can set the *trace level* - the parameter that determines how much debug information should be displayed. This value can be a number from `1` (brief) through `5` (most verbose).
 
To select a trace level, just type a number from `1` through `5` in the console.
 
Other console commands are displayed in the beginning of the console output. Moreover, you can display this list of commands by typing `h` in the console.

## What Information Can Be Found?
 
ActiveX/Java Uploader writes various information into the console. Some information makes sense for developers only, but some information can be useful for you as well, for instance:
 
- version number of the `Uploader8.jar`
- cookies which are recognized by ActiveX/Java Uploader and are about to be sent to the server
- additional POST fields which will be sent to the server
- HTTP response from the server (HTTP code as well as HTML generated by the upload processing page)
- and any other details
