It is possible to detect on the server-side something about the user's Java environment by inspecting the request headers that Java sends. There are differences when a connection is made from the Java program using URLConnection, or when a Java Web Start application is being downloaded.
Java Web Start
| Vendor | HTTP Header | |
|---|---|---|
| User-Agent | UA-Java-Version | |
| Sun | JNLP/1.5 javaws/1.5.0_19 (b02) J2SE/1.5.0_19 | 1.5.0_19 |
| Sun | JNLP/6.0 javaws/1.6.0_17 (b04) Java/1.6.0_17 | 1.6.0_17 |
| OpenJDK | Java/1.6.0_0 | (not supplied) |
URLConnection
| Vendor | HTTP header User-Agent |
