my perl script looks like this:

@list = $osm->getNodes($maxlat,$minlon,$minlat,$maxlon);

foreach my $node (@list)
{
    $node->print();
    my @list1 = $osm->getLines(($node->{"nodeid"}));
    foreach my $line (@list1)
    {
        $line->print();
    }
}

(i know .. i shold send a list of nodeids to getLines ..
but this is for a limited test area)

some values i get :

# looks like expected:

Line:
    lineid = "113697"
    point1 = "155124"
    point2 = "155125"


# here i assumed it's the streetid,
# but i always get a 14
Line:
    lineid = "148349"
    point1 = "191970"
    point2 = "191971"
    streetid = "14"


the getLines method calls the XMLRPC Method
public java.util.Vector getLines(java.lang.String sToken,
                               java.util.Vector vNodes)


this is handled by getLines() in osmServerHandler.java
which just returns getLines() from osmServerSQLHandler.java

this first gets the segment.uid, segment.node_a, segment.node_b as
expected from the database
then there is this second sql block that should add the street name

when i just had a look at this code, i noticed some problems there
(SVN Revision: 544)
- the name string is allways added, even if it's empty
- what happens if a segment belongs to more than one street
  (there is no problem to create that with
  newStreet()/addSegmentToStreet() and i also think we need that
