Openshift DIY java

Question

In my DIY Java I have this in my action_hooks start shell

cd $OPENSHIFT_DATA_DIR

export JAVA_HOME=/etc/alternatives/java_sdk_1.8.0
export PATH=$JAVA_HOME/bin:$PATH

libs="libs"

export LIB=$OPENSHIFT_REPO_DIR$libs

src="src"

export JAVA_FILES=$OPENSHIFT_REPO_DIR$src

export MATCHFACES=$OPENSHIFT_REPO_DIR$src/matchfaces


cd $OPENSHIFT_REPO_DIR

if [[ -z "$OPENSHIFT_INTERNAL_IP" ]]; then export     OPENSHIFT_INTERNAL_IP="$OPENSHIFT_DIY_IP"; fi
if [[ -z "$OPENSHIFT_INTERNAL_PORT" ]]; then export OPENSHIFT_INTERNAL_PORT="$OPENSHIFT_DIY_PORT"; fi

nohup dir $LIB > ${OPENSHIFT_DIY_LOG_DIR}/output1.log 2>&1 &

nohup javac -classpath .;$LIB/JavaBridge.jar;$LIB/FaceSDK.jar;$LIB/jna.jar $MATCHFACES/*.java > ${OPENSHIFT_DIY_LOG_DIR}/compile.log 2>&1 &

nohup java -classpath  .;$LIB/JavaBridge.jar;$LIB/FaceSDK.jar;$LIB/jna.jar $MATCHFACES/Listener > ${OPENSHIFT_DIY_LOG_DIR}/Listener.log 2>&1 &

but the code above gives me pemission denied error. from the shell above, I am trying to access a libs folder I uploaded to my repository that conatins the external dependencies my java application needs. Can anyone explain why and how to get rid of that error.

The error s below

remote: /var/lib/openshift/586b985a89f5cfe9fa0000bc/app-root/runtime/repo//.openshift/action_hooks/start: line 32: /var/lib/openshift/586b985a89f5cfe9fa0000bc/app-root/runtime/repo/libs/JavaBridge.jar: Permission denied remote: /var/lib/openshift/586b985a89f5cfe9fa0000bc/app-root/runtime/repo//.openshift/action_hooks/start: line 32: /var/lib/openshift/586b985a89f5cfe9fa0000bc/app-root/runtime/repo/libs/FaceSDK.jar: Permission denied

Automatically it seems like custom files in custom folder are not given excute permissions in runtime during execution. I realized this by running ls -l on y libs folder.

so I fixed this error by add this code to by start shell script.

#!/bin/bash
# The logic to start up your application should be put in this
# script. The application will work only if it binds to
# $OPENSHIFT_DIY_IP:8080
# nohup $OPENSHIFT_REPO_DIR/diy/testrubyserver.rb $OPENSHIFT_DIY_IP $OPENSHIFT_REPO_DIR/diy |& /usr/bin/logshifter -tag diy &
