with reference to the SPI component figure on jackrabbit site,
i guess that, for example, a jsr170 call (implemented in jcr2spi box)
is mapped to a spi call (implemented in spi2jcr box), then this spi call is
re-mapped again in a jsr170 call in the same jackrabbit instance,
and finally this call is sent to the same jackrabbit instance core, or not?

i can't understand the mean of the two red lines.

hi alessandro

does anyone give me a complete explanation of figure [...]

maybe not a complete explanation but a rough overview.
hope that helps.

what do you not understand exactly?

for example, the spi2jcr maybe means that spi calls are re-mapped to jcr calls
and are sent to a jsr170 implementation?

yes. spi2jcr is a SPI implementation that maps the SPI calls
to JCR calls again... this can be any compliant implementation.
the tests are obviously run with jackrabbit-core.

what exactly is the JSR170 box ?

interfaces and classes defined by http://jcp.org/en/jsr/detail?id=170

to which package of the jackrabbit implementation corresponds?

the JCR interfaces/classes are not owned by apache jackrabbit.
jackrabbit is the reference implementation for JSR 170.
