Hi,
I’m using Wowza 4.5.0 on an AWS Linux machine. I’ve correctly installed Java 1.8.0_91 on the machine.
Here is what I see when I type “java -version”
openjdk version “1.8.0_91”
OpenJDK Runtime Environment (build 1.8.0_91-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)
However, Wowza keeps seeing my Java as 1.7.0_55. I’ve followed the instructions at Wowza documentation on how to update Java, but still problem persists, even after I reboot the service.
Any ideas on how to solve this?
Thanks in advance!

I’ve tried if i could reproduce it. I cant update somehow. Can you tell the steps you did? Which OS are you running.
Ive tried this on a ubuntu 16.04 64bit server. Wowza version: 4.5.0
/usr/local/WowzaStreamingEngine/java/bin/java -version
result:
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
Next commands:
/usr/local/WowzaStreamingEngine/WowzaStreamingEngine/java/bin/java -version
cat /usr/local/WowzaStreamingEngine/bin/setenv.sh
result:
#!/bin/bash
if [ -d /usr/local/WowzaStreamingEngine/java ]; then
WMSJAVA_HOME=/usr/local/WowzaStreamingEngine/java
_EXECJAVA=$WMSJAVA_HOME/bin/java
else
_EXECJAVA=java
fi
# Setting of JAVA_OPTS has moved to conf/Tune.xml
WMSAPP_HOME=/usr/local/WowzaStreamingEngine
WMSCONFIG_HOME=/usr/local/WowzaStreamingEngine
WMSCONFIG_URL=
export WMSAPP_HOME WMSCONFIG_HOME JAVA_OPTS _EXECJAVA WMSJAVA_HOME
cd /usr/local/WowzaStreamingEngine/bin
sudo ./startup.sh
will result in an error at binding. I cant fix this either:
result:
root@vps287055:/usr/local/WowzaStreamingEngine/bin# sudo ./startup.sh

Hi Andrew,
thx. i can confirm this works.
rm -rf /usr/local/WowzaStreamingEngine/java
ln -sf /usr/lib/jvm/java-8-oracle/ /usr/local/WowzaStreamingEngine/java
That worked for me.
Restarted the StreamingEngine and Manager after that and now in the dashboard the java version is updated to 1.8.0_91
From what i see you already updated the documentation page?
Hello,
We are currently looking at updating the article that documents the Java upgrade. Please try the following steps instead using your jdk or jre version info:
rm -rf /usr/local/WowzaStreamingEngine/java
ln -sf /usr/lib/jvm/jdk[version]/ /usr/local/WowzaStreamingEngine/java
Best regards,
Andrew
Hello all,
Thanks for posting in our forum. We do have an article now explaining how to instruct Wowza Streaming Engine to use a specific version of Java: https://www.wowza.com/docs/manually-install-and-troubleshoot-java-on-wowza-streaming-engine#instruct-wowza-streaming-engine-to-use-a-specific-version-of-java
Kind regards,
