there are only two "implemented" for Java.

These are:

the problem could be in this file beginning at line 34

opencv / modules / java / generator / gen_java.py

there is written TODO ...

I tried taking the constants of the ignore list in the gen_java.py file and it worked ... at least for CV_CAP_PROP_FRAME_COUNT (after recompiled the whole thing).
I do not know the reason why they are on these list, but I would want to use them ... so please recheck.

I'm using 2.4.8 on Ubuntu Studio 12.04 32bit and here is what I get for propid from an Axis camera at the very beginning of a stream;

Property Id 1 value =0.0 0.0
Property Id 2 value =0.0 0.0
Property Id 3 value =8.333333333333333E-7 8.333333333333333E-7
Property Id 4 value =640.0 640.0
Property Id 5 value =480.0 480.0
Property Id 6 value =25.0 25.0
Property Id 7 value =0.0 0.0
Property Id 8 value =-1.92153584101141E14 -1.92153584101141E14
Property Id 9 value =0.0 0.0
Property Id 10 value =0.0 0.0
Property Id 11 value =0.0 0.0
Property Id 12 value =0.0 0.0
Property Id 13 value =0.0 0.0
Property Id 14 value =0.0 0.0
Property Id 15 value =0.0 0.0
Property Id 16 value =0.0 0.0
Property Id 17 value =0.0 0.0
Property Id 18 value =0.0 0.0

Prop_Pos_Msec and Prop_Pos_Frames update in value as the stream progresses.
