No view when launching executable jaamsim.jar

[Da Lu]

Hi Harry,

I exported an executable jaamsim.jar. However, when I launched the program, the view window disappeared. It worked fine when debugging and running in eclipse. Any hint?

Thanks

Da

Da,

This sounds like a problem in your build script. The standard one we use is build.xml. You can find it on GitHub in the root directory, just under LICENCE and README.md.

Thanks Harry. Problem solved.

Hi Harry,

Can you elaborate on how to make the .jar point to a new build.xml? I am having the same issue as the original poster. However, I have even tried downloading the fresh .jar from Jaamsim.com and I still cannot get the View window to appear.

Thank you,

Kyle

Kyle,

The build.xml file is used to create the jar file from the Java source code. Once you have the jar file, the build file is irrelevant.

The inability to show a view window could be caused by a graphics driver that needs an update or by running JaamSim on a terminal that is connected to a server. If you are doing the latter, your server would need a graphics processor to be able to support the 3d graphics used by JaamSim's view windows. Most servers installations do not support 3d graphics.

It was the graphics driver! (Not on a server, on my own machine). Thank you.

I currently have NVIDIA T500 with version 31.0.15.2727 which seems to be the latest version and yet face the same problem. Can you please guide me how to proceed ? Thank you

Archana,

Copy the contents of the Log Viewer to your next post. This will provide some information about what failed.

Please find the attached.

That is helpful, but the Log Viewer in JaamSim shows more information. The following image shows its normal contents:

Hi Harry , 

the log viewer is also not present when launching Jaamsim . It looks like along with the view , there is no Log viewer . None of the options in the launched Jaamsim is draggable / clickable aside from expanding the objects in the Model builder

I have clicked on the folder Jaamsim in eclipse and run.

In the Run configurations , 

Project : Jaamsim

Main class : com.jaamsim.ui.GUIFrame 

If I want to run the DemoEntity.java , do I need to make any changes to the com.jaamsim.ui.GUIFrame file ? 

Please find the attached screenshot of how Jaamsim launched looks

Got the Log viewer

Hi,

I get the following message running the jar File:

The 3D graphics system has encountered a fatal error:

Shader failed: MESH_BATCH Program link failure:
error: Too many fragment shader texture samplers

How can I fix the issue on my linux computer?

Thanks for any help.

Archana,

The Log Viewer image you provided looks like it came from a successful launch of JaamSim. Otherwise, it would show the same error traceback that you got from Eclipse. I need to see it for the JaamSim launch that failed.

Hello Harry,

Thanks for the hint with the following code:

export LIBGL_ALWAYS_SOFTWARE=1

Now JaamSim opened. Unfortunately, in a strange way. Please have a look at my video.

Log Viewer:

Operating System: Linux (version: 5.10.147-20158-g0a75306e5639)
Java: BellSoft (version: 1.8.0_352)

Found OpenGL version: 4.5 (Core profile, arb, compat[ES2, ES3, ES31, ES32], FBO, software) - 4.5 (Core Profile) Mesa 20.3.5
Found GLSL: #version 450 core

OpenGL Major: 4 Minor: 5 IsCore:true

View window created: View1

Do you know what else I can do to fix that issue?

I appreciate any help you can provide.

Hi Harry

I have attached the below short video to show you my challenge here. 

Thanks,

Hi Sascha,

I haven't seen this problem before. All the various JaamSim windows are centered in the display instead of being positioned correctly.

This might be an artifact of the BellSoft Java you are using. Try using Adoptium and see if that solves the problem.

Harry

[Harry King]

Archana,

JaamSim does not launch correctly because Eclipse is showing errors in your source code. This is probably because you have not installed the jar files for JOGL correctly.  The Java Build Path window should look something like the following:

Review the section 2.4.3  (Set-Up the JaamSim Project) in the JaamSim Programming Manual.

Incidentally, before trying to run JaamSim from Eclipse you should ensure that JaamSim runs correctly on your system when you launch it from the appropriate .exe or .jar file.

Harry

Hello,

Thanks for recommending installing Adoptium.

Unfortunately, the behavior is the same.

Below you can find the log viewer text:

Operating System: Linux (version: 5.10.147-20158-g0a75306e5639)

Java: Eclipse Adoptium (version: 17.0.5)

Loading Simulation Environment ...

OpenGL Major: 4 Minor: 5 IsCore:true
Renderer initialized
Renderer loop started
View window created: View1
RenderManager loop started
View window displayed: View1

Do you have any other suggestions on how to solve this problem?

Thank you very much

Sascha,

Try using the Java 8 version of Adoptium instead of Java 17. That would make everything as standard as possible.

Harry

[Archana R]

I switched to java 8 and now the view window appears !

I would like to debug the code in Eclipse.. Now that i am able to open Jaamsim via eclipse, does the debug statements appear in the Log viewer as well ? 
Do you suggest i use LogBox ? 

[Harry King]

In Eclipse, use the Console tab which shows everything that is written by the program to standard out and standard error.

Harry
