Running web jnlp on Ubuntu 18.04 LTS 64 - Can't load library:ibglassgtk3.so

Post by miku »

Hi all,

I need your help. Im struggling with running a jnlp web url on Ubuntu 18.04.4 LTS 64-bit

Used javac:
/usr/lib/jvm/java-1.8.0-amazon-corretto/bin/javac

Used java:
/usr/lib/jvm/java-1.8.0-amazon-corretto/jre/bin/java

Used openwebstart:
OpenWebStart 1.3.2

Everything is running completely fine on windows and mac, but when im trying to run it on ubuntu im getting following error msg:

Code: Select all

Hi

javac is irrelevant. For running an app specified in a jnlp file you need to specify in the jnlp which JRE you want to use run the app. OWS then looks for that JRE on your machine or tries to download it. You can specify using the itw-settings tool how OWS manages the JVM used to run the app. Please see

https://openwebstart.com/docs/OWSGuide.html

Also when you enable log to file there are always 2 log files created. "stage1" and "stage2".
In the stage1 log file you can find the command which is used to launch stage2. This command includes the path to the JVM for stage 2 so you can make sure that expected/required JVM is used.

Thx @Janak Mulani and @Stephan Classen.

I just see I put java and javac just to be sure, but forgot about the most important thing. :roll: That's my settings coming from the itw-settings.

I just enabled logs as @Janak Mulani suggested. The last part of the stage1 is

So it looks like its using the correct JVM. :(

Can you start the application locally (without webstart) using the exact same JVM (/usr/lib/jvm/java-1.8.0-amazon-corretto/bin/java)
JavaFX and JVM 1.8.0 with a bugfix version greater than 200 (in your case this is 282) are known to have problems

Thanks for your fast reply.

Yes, I can start the application locally (without webstart) using exact the same JVM.

Should I downgrade my version to less 200? I just quickly check corretto repository and I think they dont provide any version less than 200.

I don't think downgrading is the solution. But I am kind of running out of ideas.

Just to state the obvious:
Can you check that the file /usr/lib/jvm/java-1.8.0-amazon-corretto/jre/lib/amd64/libglassgtk3.so exists and is readable by the user which is starting the JNLP

wow, i checked it before and was pretty sure the file is there.

But I propbaly mistaken the numbers there is only libglass.so and libglassgtk2.so. libglassgtk3.so is missing. :shock:

I just tried to test to copy this file from:

1) Oracle Java - It's working (definitely not the right solution)
2) OpenFX 'https://gluonhq.com/download/javafx-11-0-2-sdk-linux/' - It's not working Im getting

Can you share the JNLP with us.

The error suggests that either a the native lib is not found or the method which the java code is trying to invoke cannot be found.
There are two likely causes.
JavaFX is not referenced correctly in the JNLP (hence we want to take a look at that file)
Or you have an incompatible version of the native lib on you computer and thus the method is not in the lib
