How hard would it be to support Java?
Quite a few apps use embedded JVM's. Case in point: SPSS, one of the apps requested by Munich. So I played around a bit with Sun's latest 1.5 JRE. It can run trivial apps, so I closed http://bugs.winehq.org/show_bug.cgi?id=2953 (ok, maybe that was premature, since the bug was for Sun's 1.4 JRE). But it can't run applets; first, it runs into a nasty glx error, http://bugs.winehq.org/show_bug.cgi?id=4143 Once you patch your way past that, it complains about not finding a native method, see http://bugs.winehq.org/show_bug.cgi?id=4873 And it doesn't show up in Firefox's about:plugins by default, see http://bugs.winehq.org/show_bug.cgi?id=4860 Can anyone shed some light on these, especially bug 4143?

WTF? There is a JVM for Linux available. To my mind contact the manufacture of your software and explain to them that Java is platform independent ...

Having it available for linux is not enough, at least wine would need to offer a wrapper dll that forwards java calls to the java engine (as executables try to hook into a java dll, and just fail if it isn't available) - the better option would ofcourse be... getting java working; I have no idea how hard that wrapper dll would be though HTH, Joris

As Joris pointed out, many apps are not pure java. Instead, they are Windows apps that load the JVM somewhere in the middle, perhaps using the JNI interface. Untangling that mess to let the Windows app part talk to a Linux JVM would be a can of worms. Sadly, the only realistic way to get apps like the SPSS client running on Linux in the next year or two may be Wine. And that means getting Sun's JVM running on Wine. When you think about it, supporting Sun's JVM on Wine is a good idea. That would let us use Java's regression test suite as an additional Wine regression test. This goes for OpenOffice, too. - Dan

As a work-around you can try to force it to use gdi. Turn off ddraw. I think their is a jvm parameter for this, can't quite recall. Another option is to set the dll override for ddraw to "". /Ulrich

Good call. -Dsun.java2d.noddraw=true does the trick, and lets you get to the more serious error. - Dan -- Wine for Windows ISVs: http://kegel.com/wine/isv
