Chromium and java

How do a make java applications run in chromium? They work fine in Firefox.
I’m using opensuse 13.1 and chromium 38.0.2125.104 (290379) (64-bit)

Short answer: you can’t. (AFAIK)

Chromium doesn’t support netscape plugins (NPAPI) any more since version 34. It only supports its own pepper plugins.
Java is only available as netscape plugin though, at least it was the last time I checked.
