[OSM-dev] Question running osmosis (node-key-value and way-key-value at the same time)

there's a global Java 1.5 installation, and a local 1.6 installation in ~/bin/
I adjusted the osmosis shell script to use the latter one and yeah, it's up 
and running! Thanks a bunch for the help.

Of course it immediately triggers the next question :) . I try to extract some 
data from an osm file which shall only contain the base net of roads, 
railways and cities. E.g. I do:
./osmosis-0.31/bin/osmosis
--read-xml file="planet.bz2"
--node-key-value keyValueList="place.city"
--way-key-value 
keyValueList="highway.motorway,highway.motorway_link,highway.motorway_junction,highway.trunk,highway.trunk_link"
--write-xml file="basemap.osm"

This only writes nodes, no ways at all. Removing the nodes, it will write 
ways:

./osmosis-0.31/bin/osmosis
--read-xml file="planet.bz2"
--way-key-value 
keyValueList="highway.motorway,highway.motorway_link,highway.motorway_junction,highway.trunk,highway.trunk_link"
--write-xml file="basemap.osm"

So I thought I need to use the pipes as found in the documentation. So I 
tried:

./osmosis-0.31/bin/osmosis
--read-xml file="planet.bz2"
outPipe.0="readpipe"
--node-key-value keyValueList="place.city"
inPipe.0="readpipe" outPipe.0="outpipe"
--way-key-value 
keyValueList="highway.motorway,highway.motorway_link,highway.motorway_junction" 
inPipe.0="readpipe" outPipe.0="outpipe"
--write-xml file="basemap.osm"
inPipe.0="outpipe"

However, osmosis does not like my syntax. I'm obviously using the pipes in a 
wrong or at least unsupported :) manner. Any hint is much appreciated. Do I 
need the pipes in this case? If so, what should I change? Or an alternative 
syntax?

Thanks & best regards,
