not able to build java

[junyanggu]

I'm trying to build java libs on Ubuntu LTS 12. I unzipped the master zip file and issued "make java" under the directory VITA49Libraries-master/vrt_src, and got the following error:

Auto-Generate Packet Documentation

mkdir -p pkt_doc

java -classpath :java_lib/vrt.jar -Dvrt.packet_factory="" nxm.vrt.libg.PacketGen --package nxm.vrt.libm --namespace vrt --HTML pkt_doc/ pkt_src/AppendixA.xml

Build Scripts

mkdir -p bin
java -classpath :java_lib/vrt.jar -DVRTHOME=/mnt/disk2/home/jgu/tmp/VITA49Libraries-master/vrt_src -DFLAGS=" -Djava.net.preferIPv4Stack=true" nxm.vrt.libg.PacketGen --dumpcshscript >& bin/packetgen
