I'm having the same issue trying to install the Java agent on a RedHat Linux machine.

wsadmin@box1 dynatrace]$ java -jar /opt/dynatrace/dynatrace-agent-6.1.0.7880-unix.jar

GNU java is not supported! Aborting installer...

[wsadmin@box1 dynatrace]$ /usr/bin/java -version

java version "1.4.2"

gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-55)

Any help?

Can you try zipping up the jre directory from the DT server, extract it into a subdirectory under /tmp on the agent server and then run the java command from that location instead?

Hi Nathan,

I think the easy way is to just use the java embedded with the dynatrace server.

You can simply extract the jre from the jar file for the server and use it on any server where you need a "bootstrap" of java to extract an install of an agent or other dynatrace component.

cp dynatrace-6.0.0.6738-linux-x64.jar /tmp
cd /tmp
mkdir java
cd java
jar xfv ../dynatrace-6.0.0.6738-linux-x64.jar jre

/tmp/java/jre/bin/java -version

java version "1.7.0_65"
OpenJDK Runtime Environment (IcedTea 2.5.2) (7u65-2.5.2-3~14.04)
OpenJDK Client VM (build 24.65-b04, mixed mode, sharing)

HTH,

dave

We are trying to extract a java .jar file on our server, but we keep getting the error:

GNU Java is not supported.

Which type of Java is supported for this?
