Never mind, found it, it is specified in the
jdp tag, under field
type (in the
build.xml file). E.g.:
PHP Code:
<rapc jdehome="${jdehome}" jdkhome="${javahome}" output="${output}" >
<jdp title="${title}" vendor="${vendor}"
version="${version}" description="${description}"
runonstartup="false" type="cldc" />
</rapc>
