Cant get Java to run on Ostro

Question

I have built a Ostro image from the current repo and built this on a 14.04 Ubuntu machine. I have successfully installed this on a target machine with intel i7-64 bit architecture. As per my opinion Java should have come packaged with this however when I type java -version on the command line (Inside the target) I get Java command not found. How to overcome this and what do I miss. Please consider me a novice in this scenario (Flashing an OS for the first time) I am also not sure how to add the Help wanted tag with this question as this is not an issue exactly and am pretty sure I am missing something. Would just need a guide here to get me started.

Also here is my bblayers.conf

# The following layers are available in the combined repository.
# Their recipes are filtered via white-listing in ostro.conf,
# i.e. even if the layer gets added, only explicitly listed recipes
# are enabled. Enable layers here only if they have enabled recipes
# to avoid warnings about empty layers.

# OSTRO_LAYERS += "/home/ubuntu/Desktop/ostro-os/meta-openembedded/meta-efl"

OSTRO_LAYERS += "/home/ubuntu/Desktop/ostro-os/meta-soletta"

BBLAYERS ?= "${OSTRO_LAYERS}"

# toaster uses this hint to decide whether it let's the user
# remove a layer from BBLAYERS. All layers which provide something
# that is required to build ostro-image should be listed here.
# We do not really track that, so add all layers also here.
BBLAYERS_NON_REMOVABLE ?= "${OSTRO_LAYERS}"

After adding the suggested part in the answer below I get:

It seems java is not being installed in your rootfs. You must include following lines in build/conf/local.conf to enable it.

# Possible provider: cacao-initial-native and jamvm-initial-native 
PREFERRED_PROVIDER_virtual/java-initial-native = "cacao-initial-native"

# Possible provider: cacao-native and jamvm-native
PREFERRED_PROVIDER_virtual/java-native = "jamvm-native"

# Optional since there is only one provider for now  
PREFERRED_PROVIDER_virtual/javac-native = "ecj-bootstrap-native"

You also need to add some of these images in build/conf/local.conf as per your requirement. These are optional. you can modify it as per your requirement.

IMAGE_INSTALL_append = " openjdk-7-jre \
openjdk-7-vm-jamvm \
openjdk-7-vm-cacao \
classpath \
classpath-common \
classpath-examples \
classpath-tools \
jamvm \
cacao \
"
