marlin renderer geoserver compatibility

Hi Marlin,

I'm currently trying to run Geoserver 2.16.2 while enabling marlin renderer.

I'm running it on Tomcat 9 and using openjdk 11.

I've followed the instruction in the How-to-use section here

https://github.com/bourgesl/marlin-renderer/wiki/How-to-use#jdk-6--8

And I'm running java with the following options for the JVM

JAVA_OPTS="$JAVA_OPTS --patch-module java.desktop=/usr/local/tomcat/marlin-0.9.4.2-Unsafe-OpenJDK9.jar"

As a result I have a running Geoserver, but I'm not able to understand if marlin renderer is correctly configured, since there are no logs saying:

INFO: ===============================================================================
INFO: Marlin software rasterizer           = ENABLED
INFO: Version                              = [marlin-X.Y.Z-Unsafe]
INFO: sun.java2d.renderer                  = org.marlin.pisces.MarlinRenderingEngine
...

I've done the same test by using openjdk 8 and setting my JAVA_OPTS as follows:

$JAVA_OPTS -Xbootclasspath/a:/usr/local/tomcat/marlin-0.9.4.3-Unsafe-sun-java2d.jar -Dsun.java2d.renderer=org.marlin.pisces.MarlinRenderingEngine"

With the same result.

Is Geoserver 2.16.2 incompatible with marlin renderer? How can I know if it is configured correctly?

Thank you,

Massimo Basile

Hi Basile,

I think logs are disabled by default:

Just add this jvm arg:

-Dsun.java2d.renderer.log=true

I recommend using -Dsun.java2d.renderer=org.marlin.pisces.DMarlinRenderingEngine

D for Double precision: better quality / same perf.

I will update the doc, it is not up to date. V0.7.5 was released in 2016 !

I can assure it rocks.

See my docker file for jdk8:

https://github.com/bourgesl/geoserver_docker/blob/master/Dockerfile

Bye,

Laurent

Hi Marlin,

Thank you very much for the quick and kind answer.

Just some points I didn’t get:

- In the wiki you wrote that for Java 9+ I should use patch module instead of -Xbootclasspath/a:/usr/local/tomcat/marlin-0.9.4.3-Unsafe-sun-java2d.jar -Dsun.java2d.renderer=org.marlin.pisces.MarlinRenderingEngine". Isn’t that correct?

- In case I use Java 11, should I add to the patch-module option also the one you mentioned in your answer (-Dsun.java2d.renderer=org.marlin.pisces.MarlinRenderingEngine) together with the one for the logs ?

- I saw your Docker image, any reason for not using Java 11?

Thanks again,

Massimo

Hi Laurent,

Unfortunately I was not able to enable the marlin rasterizer, even with your precious suggestions.

After trying to replicate as close as possible what you've done with the docker image you posted, I decided to make a test by pulling that image.

What I've came up with is something I didn't expect, that image has my same problem, logs don't appear and as you can see in the screenshot the MarlinRendered is not enabled.

I've simply run this command:

docker run -p 8081:8080 ianturton/geoserver-2.16-jdk-8-zoomstack:latest

So, don't know how to proceed :(

Thank you,

Massimo

Hi,

Just follow instructions:

Hi Laurent,

thanks again, actually it was my fault. I run your image and is working correctly.

Going back to my problem, here is my Dockerfile:

FROM tomcat:jre8

ARG TOMCAT_APPS_PATH=${CATALINA_HOME}/webapps

WORKDIR ${TOMCAT_APPS_PATH}

COPY geoserver2.15.war geoserver.war

COPY marlin-0.9.4.3-Unsafe-sun-java2d.jar $CATALINA_HOME

COPY marlin-0.9.4.3-Unsafe.jar $CATALINA_HOME

ENV MARLIN_JAR_PREFIX=$CATALINA_HOME/usr/local/tomcat/marlin-0.9.4.3-Unsafe

ENV JAVA_OPTS="-Xbootclasspath/a:$MARLIN_JAR_PREFIX.jar -Xbootclasspath/p:$MARLIN_JAR_PREFIX-sun-java2d.jar -Dsun.java2d.renderer=org.marlin.pisces.DMarlinRenderingEngine -Dsun.java2d.renderer.log=true"

It's a very simple one, using tomcat 8 and moving the geoserver war under webapps.

No way to see the renderer enabled.

Do you see any problem in this Dockerfile?

Thank you,

Massimo

The problem seems to be here? The MARLIN_JAR_PREFIX should probably be just "$CATALINA_HOME//marlin-0.9.4.3-Unsafe" (or something like that)

Hi Andrea,

yes in the meanwhile I saw it and fixed, I just forgot to remove that path when I used that environment variable.

Not it is working.

Thank you,

Hi Laurent,

Now it works simply fine thanks to your advises. I was able to run it in java 11 too.

I have just one last doubt:

.- Version 0.9.4.3 includes two jars, and uses -Xbootclasspath/a and -Xbootclasspath/c for setting the render on the JVM. This seems to be compatible only for java 8-

- Version 0.9.4.2 supports java 9+ but have just one jar (marlin-0.9.4.2-Unsafe-OpenJDK9.jar)

What's the difference between them?

What is more convenient to use?

Best regards,

Massimo

Just check your paths !

ENV MARLIN_JAR_PREFIX=$CATALINA_HOME/usr/local/tomcat/marlin-0.9.4.3-Unsafe

=>

ENV MARLIN_JAR_PREFIX=$CATALINA_HOME/marlin-0.9.4.3-Unsafe

That's your turn to make it work.

Yes: the extra jar contains fixes (png, aa shape tile...) that are specific to jdk8. Jdk11 has these fixes as I pushed them myself.

- Version 0.9.4.2 supports java 9+ but have just one jar (marlin-0.9.4.2-Unsafe-OpenJDK9.jar)

That patch upgrades the marlin renderer 0.9.1.3 to latest release for jdk11+: that's the only jar to have.
