I am reading sun's JTA Spec now. But I cannot
understand the table of Transaction Association in
P17 of the spec.

I know there may be serveral interleave transactions associating the same XAResource at the different
time. And the table just wants to show me how it is
done. but I am failed to understand the table.

I donot know what it means.

Could anybody do me a favor to explain that?

thanks.
