HelloManager seems to be an example code written for the tutorial. Did you write and compile this into your jar file? However, there is no module named igniotionphone, unless you wrote it?

> Ah, in order for client/designer scoped jars to get loaded you have to run the pack200 tool on the jar first. You'll notice those directories are full of jar.pack.gz files - these are packed jars.

Hi Kevin, i have same problem , write un jar and i need using in designer for ejecute in button, i have compile it and run de pack200 to generare of jar.pack.gz . place file in core/lib/commom also core/lib/designer but no work.

</div>

If you’ve used the pack200 utility and placed both the \*.jar and \*.jar.pack.gz files in  
`core/common/`

you still need to restart the gateway and the designer (I believe) before they show up in  
`user/yourusername/.ignition/cache/resources/platform/`

for use by the platform at runtime.

Does anyone know where the equivalent location for the above path is for linux OS’s?

(i.e. the `user/yourusername/.ignition/cache/resources/platform/` path)

`~/.ignition` or `/home/<username>/.ignition`  
Note that the `.` prefix signifies a file as hidden in Unix OSes, so you usually need to go through some extra step to list hidden files (eg, `ls -a` or Ctrl + H in Ubuntu’s GUI file explorer).

Wow, lightning fast and very cogent. Much appreciated Paul. I skimmed around in all the obvious places for a while. That . notation is so key!! My Linuxfoo is much more tight now.

> I have been trying to add the Apache POI jar to my gateway using this method, but when I run a button with the following code under it

I am in the same situation right now but with a different third party jar. I have dropped the jar in ignition/lib/core/common, gateway and client folders but my script is unable to see these libraries giving same results that you mentioned. Should I have to restart Ignition server ? I am using windows 10. How did you solve the problem?

I had to bundle the version of POI (3.14) in my module to match what is being used by the reporting module.  
If you know what the version is in the Client/Designer scope you should be able to do the same thing.

My module is new and its not used in Ignition gateway or server scope. So the question of matching the versions doesn't exist for me I guess.

Hello,  
I need pdfbox-app-2.0.27.jar to provide silent pdf printing from client scope (generate few pdfs by system.report.executeReport and print it at once with print job.

I add jar file to folders Ignition\lib\core\Clinet , Ignition\lib\core\Designer, Ignition\lib\core\Common  
I`m able to add module for designer scope. It automatically download module at designer startup, and I can execute script in designer.

What I have to makes library available in client scope ?  
Probably I need to provoke Ignition to add this library to lunch manifest system/launchmf/C?os=windwos&arch=x64

</div>

I don't know what pdfbox is actually getting you, if you're just using reports from `system.report.executeReport`, but putting it in _either_ `lib/core/common` or `lib/core/client` should be sufficient. If you're on 7.9, you'll have to `pack200` the .jar file, I believe, but that requirement is nixed in 8.0+

Have you restarted the gateway since installing the jar? It should be delivered in client scope 🤷‍♂️

This whole approach is not supported, as mentioned above. The way to ensure this works is to use a custom module.

Yes, I do restart after placing the files into lib/core/\* folders.

So challenge accepted, I going to create custom module 😉

I have added the pdfbox.jar in client, common and gateway folder. But getting error as "No module named pdfbox". Will it work if we add only the jar file? What do you mean by create custom module?

It not working. You have to build module using API and IntelliJ IDEA.  
I do it like that, and it works.
